This document discusses black holes, including their properties, structure, formation, observational evidence, and role in the universe. It defines a black hole as a region of space where gravity is so strong that not even light can escape. Black holes are formed when a massive star collapses at the end of its life. They distort both space and time and can grow by absorbing matter or merging with other black holes. Observational evidence of black holes includes analyzing the motion of stars around black holes, detecting x-ray emissions from accretion disks, and observing gravitational lensing. Black holes play an important role as energy recyclers in the universe and act as seeds for the formation of galaxies.

Black holes
This document discusses black holes. It begins with a brief history of ideas about black holes from the 18th century to modern times. It then describes how black holes form from massive stars undergoing gravitational collapse at the end of their life cycles. It outlines the key characteristics of black holes, including their structures consisting of singularities surrounded by event horizons. The document also notes that black holes can continue growing by absorbing matter and merging with other objects. In conclusion, it states that while there is no limit to the size of black holes, the largest are likely in the centers of galaxies and contain billions of solar masses.
Black holes final presentation
Einstein's theory of general relativity first predicted the possibility of black holes in 1915, but they were not widely accepted to exist until 1970 when Hawking provided evidence. Today, NASA telescopes have found evidence of black holes throughout the universe. Black holes are extremely dense objects that have such strong gravity that not even light can escape. If one were to fall into a black hole, an outside observer would not be able to see them as the gravitational pull would bend and distort all light.
Mike Micallef Black Holes
Black holes are formed when massive stars collapse in on themselves after exhausting their nuclear fuel. The collapsed star's immense gravity causes even light to be unable to escape, creating an event horizon around the black hole. There is strong evidence that supermassive black holes exist at the centers of galaxies, helping to shape their structure and hold stars in orbit. Black holes can continue growing by absorbing nearby matter and other objects that come too close and cross the event horizon.
Black holes (2)
Black holes are formed when giant stars collapse under their own gravity. If the star's mass is large enough, its gravitational pull becomes so strong that not even light can escape, forming an event horizon around the black hole. Anything that crosses this boundary, including light, cannot escape the black hole. Black holes can also rotate, forming an ergosphere outside the event horizon where the rotation of the black hole drags spacetime itself along. While black holes themselves are invisible, astronomers can detect them through their interaction with nearby matter and the strong gravitational lensing they produce.
Black holes presentation
Black holes are objects with extremely strong gravitational fields that do not allow anything, including light, to escape once it passes the event horizon. They are formed when very massive stars collapse at the end of their life cycles. Black holes are small but incredibly dense, with all their mass concentrated at a central singularity. If material such as gas from a nearby star falls into a black hole, it becomes heated and glows, making the black hole visible with telescopes.
Black holes
Black holes are regions of spacetime where gravity is so strong that nothing, not even light, can escape. They form when massive stars collapse at the end of their life cycles. There are two main types - stellar black holes, which are relatively small and formed by collapsing stars, and supermassive black holes, which are much larger and found at the center of galaxies. Black holes are invisible but can be detected through their interaction with nearby stars and gas.
BLACK HOLE-THE OTHER DIMENSION
"Black holes are where God divided by zero" - Albert Einstein
Black hole – A region in the space where the gravitational pull is so strong that neither substance nor light can leave this area.
Black Holes and its Effects
1. Black holes are regions of space where gravity is so strong that nothing, not even light, can escape. They form when massive stars collapse at the end of their life cycles.
2. There are two main types of black holes - static and rotating. The rotating type, known as Kerr black holes, form when collapsed stars have angular momentum.
3. As a star collapses, it passes through stages as a red giant, white dwarf, and neutron star until its mass exceeds around 3 solar masses, causing it to collapse entirely into a black hole with a singularity at its center.

Pulsars and black hole
Pulsars are rapidly rotating neutron stars that emit beams of electromagnetic radiation. They were discovered in 1967 and form during supernova explosions when massive stars collapse. Pulsars appear to pulse because they rotate and emit beams of radiation that sweep across space like a lighthouse, appearing brighter when facing Earth. They are very dense and spin very quickly due to their compressed gravity. Black holes form when massive stars collapse at the end of their life and have such strong gravity that not even light can escape. They come in different sizes from stellar to supermassive and are detected by their effects on nearby stars. The event horizon marks the boundary where light cannot escape from a black hole's strong gravity.
Black hole
A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying.
Because no light can get out, people can't see black holes. They are invisible. Space telescopes with special tools can help find black holes. The special tools can see how stars that are very close to black holes act differently than other stars.

Black holes
Black holes are regions of space where gravity is so strong that nothing, not even light, can escape. They form when large stars collapse at the end of their life cycles, compressing their mass into a tiny space. There are several types of black holes including stellar black holes formed by collapsed stars and supermassive black holes found at the center of galaxies containing billions of solar masses. If matter enters a black hole's event horizon, it becomes "spaghettified" as tidal forces stretch and compress it due to the extreme warping of spacetime.
Sarita chauhan seminar presentation
The document summarizes the layers of the Sun and what they are composed of. It discusses that the core of the Sun undergoes nuclear fusion, combining hydrogen into helium. This reaction powers the Sun and releases energy. The energy moves outward through the radiative zone by radiation and then the convective zone carries the energy to the surface by convection currents. The visible surface is the photosphere, which has a temperature of around 6000 Kelvin and emits light.
An Introduction about The Black Hole and its types
Black holes are regions of space where gravity is so strong that nothing, not even light, can escape. They form when massive stars over 8 times the sun's mass die in supernova explosions. Billions of black holes exist between galaxies and millions exist within our own Milky Way galaxy. Black holes can be detected by their gravitational effects on nearby stars and the intense light produced from material falling into supermassive black holes at galaxy cores. Orbiting black holes is possible only at precise speeds - too slow will lead to spiraling in, too fast will escape, and intermediate speeds result in complex rosetta orbits.
Black Hole By Pranita & Priyanka
Black holes are objects with such strong gravity that not even light can escape. They form when massive stars collapse at the end of their life cycles. Black holes come in different sizes, from stellar-mass black holes formed by collapsed stars to supermassive black holes millions of times the sun's mass found at the centers of galaxies. Though we cannot see a black hole directly, astronomers can detect them through their effects on nearby objects like gases and stars.
Black Holes
Black holes are areas of extremely dense mass that have such strong gravitational pull that not even light can escape. They are formed when giant stars collapse at the end of their life cycles. Black holes can range significantly in size, from around 6 miles across to larger than our entire solar system. Scientists identify black holes by observing the orbits and emissions of objects near them, like stars and gas, using instruments that detect x-rays, radio waves, and other forms of light.

Black holes are regions of spacetime where gravity is so strong that nothing, not even light, can escape. They form when massive stars collapse at the end of their life cycle. Black holes absorb surrounding matter and other objects, growing increasingly massive over time. Scientists have discovered that black holes may affect the passage of time and have links to accretion disks and plasma jets. Different types of black holes are defined based on their rotation and electric charge.

There are three main types - miniature, stellar, and supermassive black holes. Stellar black holes form from collapsed stars, while supermassive black holes exist at the center of most galaxies including the Milky Way. Black holes have strong gravitational pulls that distort spacetime and prevent anything from escaping, making them act like ideal blackbodies.
15 Mind-Boggling Facts About Black Holes- The Cosmic Enigmas.pdf
In this presentation, we unravel 15 captivating data approximately black holes, shedding mild on their ordinary nature and the profound impact they have on the material of the universe. In the widespread expanse of our universe, black holes stand as enigmatic cosmic wonders, fascinating both astronomers and space fanatics alike. These mysterious entities, born from the gravitational fall apart of huge stars, have the energy to warp space and time in methods that challenge our knowledge of the cosmos.
1. Invisible Entities: Black holes are areas in area in which gravity is so extreme that nothing, not even light, can escape from them. They are basically invisible, making their detection tough. Scientists regularly rely upon indirect proof, inclusive of looking at the outcomes of a black hollow’s gravity on nearby stars.
2. Formation from Collapsed Stars: Most black holes are fashioned while massive stars exhaust their nuclear gas and disintegrate under their very own gravity. This fall apart can arise after a supernova explosion, leaving in the back of a dense center with gravitational forces so strong that now not even light can break out.
3. Three Types of Black Holes: There are 3 essential forms of black holes: stellar black holes, intermediate black holes, and supermassive black holes. Stellar black holes are shaped from collapsing stars, intermediate black holes have loads among one hundred and 100,000 instances that of the solar, and supermassive black holes, found at the centers of galaxies, may have hundreds equal to millions or even billions of suns.
4. Size Doesn’t Matter, Mass Does: The length of a black hole is defined with the aid of its occasion horizon, the boundary past which not anything can break out its gravitational pull. Contrary to popular perception, the size of the occasion horizon does now not rely on the mass of the item that fashioned the black hollow. A black hole with the mass of our sun would have an occasion horizon of only a few kilometers.
5. Time Dilation: Near a black hole, time behaves differently due to the intense gravitational forces. This phenomenon, called time dilation, method that time passes more slowly for an observer close to a black hole in comparison to a person farther away. This impact has been confirmed through numerous experiments and observations.
6. Hawking Radiation: Theoretical physicist Stephen Hawking proposed that black holes aren’t completely black; they emit a faint radiation now referred to as Hawking radiation. This happens due to quantum outcomes near the occasion horizon, inflicting pairs of debris to be created and one falling into the black hollow whilst the opposite escapes as radiation.
7. Spaghettification: As an item gets towards a black hollow, the gravitational forces grow to be an increasing number of stronger on one facet as compared to the opposite. This tidal force stretches the item into an extended, skinny shape, a manner humorously called “spaghettification.”

What is a black hole
Black holes are regions of space where gravity is so strong that not even light can escape. They form when very massive stars collapse at the end of their life cycles. While black holes cannot be seen directly, astronomers can detect them by observing their effects on nearby objects like stars and gas, and through detection of x-rays emitted during accretion. Black holes come in different sizes, from stellar-mass black holes up to supermassive black holes that may exist at the centers of galaxies.

What is a black hole
Black holes are regions of space where gravity is so strong that not even light can escape. They form when very massive stars collapse at the end of their life cycles. While black holes cannot be seen directly, astronomers can detect them by observing their effects on nearby objects like stars and gas, and through detection of x-rays emitted during accretion. Black holes come in different sizes, from stellar-mass black holes up to supermassive black holes that may exist at the centers of galaxies.
Black hole
A black hole is a region of space where gravity is so strong that nothing, not even light, can escape. They form when massive stars collapse at the end of their life cycles. There are several types of black holes including stellar black holes formed by collapsed stars and supermassive black holes millions to billions times the mass of our sun. As objects fall into a black hole's event horizon, they become "spaghettified" as the black hole's immense gravity stretches and pulls them apart.
Question 6 group 13
A black hole is a region of space where gravity is so strong that not even light can escape. It forms during the collapse of a massive star and contains a singularity, where all laws of physics break down, within an event horizon boundary that allows matter to enter but not exit the black hole. Black holes can continue growing by absorbing surrounding matter and merging with other black holes.
Black holes
1) Black holes are formed when massive stars over 10 times the mass of the Sun collapse in on themselves due to nuclear fusion and strong gravitational forces.
2) We can detect the presence of black holes through the X-rays emitted when matter around the black hole is heated and through gravitational lensing effects on light passing by.
3) If you fell into a black hole, you would experience immense tidal forces that would spaghettify your body as you approached the singularity at the center, where gravitational forces become infinite and space and time become distorted.

Black hole is a region of space having a gravitational field so intense that no matter or radiation can escape.
Black hole
1) A black hole is a region of spacetime where the gravitational pull is so strong that nothing, not even light, can escape.
2) The boundary of this region is called the event horizon. Although nothing can escape the event horizon, it appears to have no detectable features from within.
3) Black holes form when very massive stars collapse at the end of their life cycle. They can continue growing by absorbing mass and merging with other black holes, potentially forming supermassive black holes containing millions of solar masses.

Black holes are the most mysterious objects in the Universe. Black holes are huge hungry monsters which even devours light. Yes, even light cannot escape the black hole.
Black Holes
This document provides information about black holes, including their structure, theories about their formation and properties, and how they are detected. It discusses that a black hole has a singularity at its center with infinite density, is surrounded by an event horizon beyond which nothing can escape, and may be accompanied by an accretion disk and jets. It also describes Sagittarius A*, the supermassive black hole at the center of the Milky Way, and Cygnus X-1, the first identified black hole.
Mike Micallef Black Holes
Black holes are formed when massive stars collapse in on themselves after exhausting their nuclear fuel. The collapsed star becomes incredibly dense, with such strong gravity that not even light can escape. There are two main types - galactic black holes, which are relatively smaller and formed from collapsed stars, and supermassive black holes, which are millions to billions times the mass of our sun and reside at the center of most galaxies. The event horizon marks the point at which a black hole's gravity becomes so intense that nothing, not even light, can escape.

1) A black hole is a region of spacetime where gravity is so strong that nothing, not even light, can escape. It has an event horizon boundary that marks the point of no return.
2) Black holes form when very massive stars collapse at the end of their life cycle. Supermassive black holes millions of times the mass of our sun may form at the centers of galaxies through mergers with other black holes and stars.
3) While black holes themselves are invisible, their presence can be inferred through their interaction with nearby matter like gas and stars. This surrounding material often forms an accretion disk and bright radiation that astronomers can observe.

Black holes are regions of space where the gravitational pull is so strong that nothing, not even light, can escape. Surrounding the black hole is an event horizon, which marks the point of no return beyond which the gravitational forces are inescapable. Albert Einstein's theory of general relativity first theorized black holes by explaining how gravity can bend space and time. Black holes have immense gravitational forces that can feed on and destroy stars that come too close, collapsing them into the black hole. The largest known black holes are supermassive black holes that can be millions of times the size of our sun.
Black holes definitivo
Black holes form from dying massive stars and are regions of space where gravity is so strong that nothing, not even light, can escape. They have an event horizon boundary and extreme density at the singularity at the center. Small stellar black holes form from supernovae, while supermassive black holes with masses of billions of suns are found at the centers of galaxies. Matter falling into a black hole's intense gravity is stretched or "spaghettified" as it crosses the event horizon.

This document provides an overview of black holes, including what they are, how they form, different classifications, and some key facts:
- Black holes are areas in space where gravity is so strong that not even light can escape. They form when massive stars collapse in on themselves at the end of their life cycles.
- There are three main classifications of black holes: primordial, stellar, and supermassive. Supermassive black holes exist at the center of galaxies and are millions of times the mass of our sun.
- Although powerful, black holes far away like the one at the center of our Milky Way galaxy do not pose a threat to Earth. A black hole would need to be very close to
The black hole
Black holes are regions of space where gravity is so strong that nothing, not even light, can escape. They form when large stars collapse at the end of their life cycles, squeezing matter into an infinitely small space where density and gravity become infinite. Albert Einstein first predicted black holes in 1916, and the term was coined by John Wheeler in 1967. At the center of a black hole is a gravitational singularity, and its powerful gravity is why black holes were long thought to be completely dark, though Hawking radiation shows they may emit some light.
Dark matter
Dark matter is invisible matter that makes up about 21% of the universe. It cannot be seen directly but its existence and properties are known through its gravitational effects on visible matter. There are two main types of dark matter: ordinary matter made up of normal particles and extraordinary dark matter like black holes. Dark matter was first proposed in 1933 by Fritz Zwicky to explain discrepancies in galaxy motions but its exact nature remains mysterious. Current experiments aim to detect dark matter particles but have had conflicting results so far.
Black Holes
This document provides information about black holes, including their structure, formation theories, detection methods, and two specific black holes - Sagittarius A* and Cygnus X-1. It describes the key components of black holes as the singularity at the center with infinite density, the event horizon boundary, and accretion disks of spiraling material. It also discusses theories such as black holes forming from collapsed stars and acting as tunnels to other universes. Sagittarius A* is identified as the supermassive black hole at the center of the Milky Way, while Cygnus X-1 was the first galactic black hole candidate discovered.

EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.

Unlocking the mysteries of reproduction: Exploring fecundity and gonadosomati...
The pygmy halfbeak Dermogenys colletei, is known for its viviparous nature, this presents an intriguing case of relatively low fecundity, raising questions about potential compensatory reproductive strategies employed by this species. Our study delves into the examination of fecundity and the Gonadosomatic Index (GSI) in the Pygmy Halfbeak, D. colletei (Meisner, 2001), an intriguing viviparous fish indigenous to Sarawak, Borneo. We hypothesize that the Pygmy halfbeak, D. colletei, may exhibit unique reproductive adaptations to offset its low fecundity, thus enhancing its survival and fitness. To address this, we conducted a comprehensive study utilizing 28 mature female specimens of D. colletei, carefully measuring fecundity and GSI to shed light on the reproductive adaptations of this species. Our findings reveal that D. colletei indeed exhibits low fecundity, with a mean of 16.76 ± 2.01, and a mean GSI of 12.83 ± 1.27, providing crucial insights into the reproductive mechanisms at play in this species. These results underscore the existence of unique reproductive strategies in D. colletei, enabling its adaptation and persistence in Borneo's diverse aquatic ecosystems, and call for further ecological research to elucidate these mechanisms. This study lends to a better understanding of viviparous fish in Borneo and contributes to the broader field of aquatic ecology, enhancing our knowledge of species adaptations to unique ecological challenges.

ESR spectroscopy in liquid food and beverages.pptx
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.
Immersive Learning That Works: Research Grounding and Paths Forward
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.
Applied Science: Thermodynamics, Laws & Methodology.pdf
When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.
Deep Software Variability and Frictionless Reproducibility
Deep Software Variability and Frictionless ReproducibilityUniversity of Rennes, INSA Rennes, Inria/IRISA, CNRS
The ability to recreate computational results with minimal effort and actionable metrics provides a solid foundation for scientific research and software development. When people can replicate an analysis at the touch of a button using open-source software, open data, and methods to assess and compare proposals, it significantly eases verification of results, engagement with a diverse range of contributors, and progress. However, we have yet to fully achieve this; there are still many sociotechnical frictions.
Inspired by David Donoho's vision, this talk aims to revisit the three crucial pillars of frictionless reproducibility (data sharing, code sharing, and competitive challenges) with the perspective of deep software variability.
Our observation is that multiple layers — hardware, operating systems, third-party libraries, software versions, input data, compile-time options, and parameters — are subject to variability that exacerbates frictions but is also essential for achieving robust, generalizable results and fostering innovation. I will first review the literature, providing evidence of how the complex variability interactions across these layers affect qualitative and quantitative software properties, thereby complicating the reproduction and replication of scientific studies in various fields.
I will then present some software engineering and AI techniques that can support the strategic exploration of variability spaces. These include the use of abstractions and models (e.g., feature models), sampling strategies (e.g., uniform, random), cost-effective measurements (e.g., incremental build of software configurations), and dimensionality reduction methods (e.g., transfer learning, feature selection, software debloating).
I will finally argue that deep variability is both the problem and solution of frictionless reproducibility, calling the software science community to develop new methods and tools to manage variability and foster reproducibility in software systems.

The debris of the ‘last major merger’ is dynamically young
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.

Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.

- 3. Introduction A black hole is a region of space in which gravity is so strong that even light cannot escape it. This region is formed due to huge amount of matter in an infinitely small point. Data Source: NASA Image Source: geekspace.com
- 4. What would happen if our sun is replaced with a black hole of same mass???
- 5. Contrary to popular belief, the solar system wouldn’t be sucked in; a solar mass black hole would exert no more gravitational pull than our sun.
- 6. Properties of Black Holes ● It is not mass, but their size which matters. ● They distort space as well as time. ● Gravitational Lensing ● Black Holes can grow in size by sucking matter or merging with other black holes. ● Black Holes eventually evaporate over time.
- 7. Structure of Black Holes ● In layman's terms, Event Horizon is defined as "the point of no return". ● Singularity is a one-dimensional point which has infinite mass in a point space and where the laws of physics as we know cease to operate.
- 8. Formation of Black Holes: Supernova When a star, generally 5 or more times massive than our sun, has its hydrogen given out, it switches to helium, then carbon, then ultimately to iron. Now, fusion of iron doesn’t release energy, and in a fraction of second, due to its own weight, the star compresses into a black hole.
- 10. Death of Black Holes: Hawking Radiation ● A black hole too dies with time, if it doesn’t absorb any matter for a sufficiently long time ● Hawking showed that quantum effects allow black holes to emit exact black body radiation. The electromagnetic radiation is produced as if emitted by a black body with a temperature inversely proportional to the mass of the black hole.
