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. There are two main types - stellar black holes, which are relatively small and form from collapsed stars, and supermassive black holes, which are millions to billions of times the mass of our sun and reside at the center of most galaxies. Although black holes themselves are invisible, astronomers can detect them through their effects on nearby stars and gas.

There are several theories about what black holes are and what may happen when something falls into one. Some theories are that black holes destroy all matter and suck it into "oblivion", while others believe black holes could be "wormholes" or portals that transfer matter to other locations or dimensions. When large stars collapse, they can form either neutron stars or black holes, where the gravitational pull is so strong that it destroys the star from within forming an infinite density. What happens when something falls into a black hole is unknown, but theories include the object being "spaghettified" and stretched into thin strands or snapped apart by tidal forces before being fully dismantled.
Black holes are regions of space with immense gravitational pull that not even light can escape. They have a boundary called an event horizon inside of which matter becomes infinitely dense. Stephen Hawking theorized that black holes transform what enters them and eject it when they evaporate, while a 2012 doomsday theory claimed a black hole would destroy Earth. Scientists search for black holes by looking for areas with large concentrated mass that emit no light.
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.
This document provides a history and overview of black holes. It discusses that the idea of black holes was first proposed by John Mitchell in the 18th century. Key developments include Einstein's theory of relativity in 1915 and the work of Israel, Carter and Robinson establishing the no-hair theorem in the 1970s. The term "black hole" was first publicly used by John Wheeler and first recorded in an article by Ann Ewing. The document then covers the classification, features and examples of different types of black holes such as their event horizons, singularities, photon spheres, and ergospheres. Black holes can be supermassive, stellar-mass or hypothetical micro black holes. They are also classified based on their properties as
1. The document discusses the history and formation of black holes. It explains that black holes were first conceptualized by scientists like Michell, Laplace, Einstein, and Schwarzschild and can form when massive stars collapse at the end of their life.
2. It provides classifications of black holes based on mass and describes their characteristics like intense gravity and density that causes even light to be trapped. Accretion disks and plasma jets are also summarized.
3. Detection methods are summarized, noting that black holes cannot be seen directly but their effects like gravitational lensing and orbits of nearby stars can provide evidence of their existence.
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.

This document provides information about black holes from an engineering physics course. It contains the following key points:
1) A black hole is a region of space where the gravitational field is so strong that nothing, not even light, can escape. It is formed when a massive star collapses under its own gravity.
2) Around a black hole is an event horizon, which marks the point of no return. Beyond this, not even light can escape the black hole's gravitational pull.
3) There are several theories about how black holes form, but most commonly it is believed they are formed when a massive star over 3 times the sun's mass reaches the end of its life and collapses.

A black hole is formed when a massive star collapses under its own gravity at the end of its life. It creates a region of space where the gravitational pull is so strong that nothing, not even light, can escape. Black holes were first theorized in the 18th century and their existence was predicted by Einstein's theory of general relativity. They have been observed through their effects on nearby stars and gas and the emission of x-rays. Black holes come in different sizes from stellar black holes formed by collapsed stars to supermassive black holes millions of times the sun's mass at the center of galaxies.
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.

A black hole is an object with such strong gravity that not even light can escape, and as material is pulled in it is accelerated, heated, and emits x-rays. The existence of black holes was first proposed in the 18th century based on known laws of gravity. John Wheeler introduced the term "black hole" in 1967, and while they were once science fiction, astronomers have now identified billions of black holes in the universe by observing material falling into them.
A REVIEW ARTICLE ON BLACK HOLE A MYSTERY IN THE UNIVERSEKelly Taylor
This article reviews black holes, mysterious celestial objects with gravitational pulls so strong that not even light can escape. It discusses the historical background of black hole theory, defines what a black hole is, describes different types including stellar, supermassive, and microscopic black holes. The formation of black holes from collapsing stars is explained. While black holes pose no threat to life on Earth, objects close to a black hole's event horizon would be stretched out in a process called spaghettification. Though black holes themselves are invisible, astronomers can detect them through gravitational effects on nearby objects and energetic x-ray emissions from accretion disks.
The universe: why does it exist? Why is there something rather than nothing? Where and why did structure arise: galaxies, and clusters of galaxies. This slide show is a full history of enquiry into how structure arises in the universe. It goes from Plato and Aristotle to the Nobel Prize in Physics 2011.

An Introduction about The Black Hole and its typesSenthil Kumar
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.
The document provides information about black holes from a physics group at Jahangirnagar University. It discusses the history of black hole theory, what a black hole is, how they form from massive stars, their properties including singularities and event horizons, evidence of their existence, Stephen Hawking's contributions, and some facts about black holes. The document contains sections on the history, formation, properties, detection, Hawking's work, and interesting facts about black holes. It aims to explain black holes and solve the mystery of these astronomical objects.
The document discusses black holes, including their definition, structure, properties, classifications, and how astronomers detect them. Black holes are very dense objects with gravity so strong that not even light can escape. They are categorized into stellar, supermassive, and primordial black holes. Astronomers find evidence for black holes' existence by observing their effects on nearby matter like heating dust that emits x-rays, or by measuring the mass of an unseen object that is gravitationally influencing a companion star. Black holes are theorized to exist at the centers of most galaxies.
This document discusses black holes and some of the key contributors to the field of black hole research. It provides information on what a black hole is, defines key terms like the event horizon, and discusses the goal of understanding the term "black hole" and learning about important contributors and discoveries. Three contributors are highlighted: John Michell who first proposed the idea of a body so massive that light could not escape in 1783; Albert Einstein whose theory of general relativity helped establish the modern concept of black holes; and Stephen Hawking who showed in 1974 that black holes emit thermal radiation known as Hawking radiation.
The document summarizes what is known about black holes, including:
- Einstein's theory of general relativity predicted black holes could exist, though they were not believed to be real until convincing evidence in the 1970s.
- Black holes are extremely dense regions with gravity so strong that not even light can escape, where the escape velocity exceeds the speed of light.
- Observational evidence like hot material falling into black holes and jets of glowing gas have shown that while invisible, black holes' effects can be observed and they are widespread throughout the universe.

Black holes are regions of space where gravity is so strong that nothing, not even light, can escape. They have an event horizon surrounding a singularity of infinite density. There are three main types - stellar black holes formed by collapsed stars, supermassive black holes millions of times the sun's mass at galaxy centers, and miniature black holes theorized to have formed in the early universe. Scientists can observe black holes indirectly by their effects on nearby stars and gas. In 1915, Einstein's theory of general relativity predicted black holes, and breakthroughs by scientists like Hawking and Chandrasekhar helped establish our modern understanding of these mysterious cosmic objects.
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 are predicted by Einstein's theory of general relativity and are formed when massive stars collapse at the end of their life cycle. They have immense gravitational pull such that not even light can escape, creating a region of space-time known as the event horizon. Beyond this point, time stops and space ceases to exist, forming a gravitational singularity. Though small, black holes have such intense gravity that they can affect objects orbiting much larger stars and galaxies.

THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...indexPub
The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.
