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.

Do We Live in a Black Hole? Modern Conceptions of the MultiverseLuke Conlin
Modern physics grapples with some of humankind’s biggest questions: ‘Why is the universe the way it is? And why are we here, able to ask the question?’ In their search for answers, leading physicists have been considering some wild ideas, including the existence of multiple universes (the ‘multiverse’) and the possibility that we may actually be living in a black hole. I will explain the physics behind these wild ideas, describe how they might answer our biggest questions, and lay out the prospects for finding observational evidence to support or refute them.
It is said that fact is sometimes stranger than fiction, and nowhere is this more true than in the case of black holes. Black holes are stranger than anything dreamt up by science fiction writers, but they are firmly matters of science ~fact.

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.

this ppt is made by shantanu milkhe, it contain everthing about black hole, its my full i can share, so please watch it. and follow me at my intagram https://www.instagram.com/shantanu_stark/?hl=en
Hey I'm DIVYA SHREE NANDINI. I'm here with my new presentation on Black Hole. I'm sure you'll find it interesting. well first thing what is black hole- "Black hole, cosmic body of extremely intense gravity from which nothing, not even light, can escape. A black hole can be formed by the death of a massive star. When such a star has exhausted the internal thermonuclear fuels in its core at the end of its life, the core becomes unstable and gravitationally collapses inward upon itself, and the star’s outer layers are blown away. The crushing weight of constituent matter falling in from all sides compresses the dying star to a point of zero volume and infinite density called the singularity." wanna know more about it then come with me. :)

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

3. BLACK HOLES: WHAT ARE
THEY?
Black holes are the evolutionary
endpoints of stars at least 10 to
15 times as massive as the Sun.
4. Facts and figures
Black holes are objects so dense that not even
light can escape their gravity , and since nothing
can travel faster than light, nothing can escape
from inside a black hole.
For example, if our Sun is magically crushed until
it becomes about 1 mile in size, it would become
a black hole, but the Earth would remain in its
same orbit.
Even back in Isaac Newton's time, scientists
speculated that such objects could exist.
5. FORMATION OF BLACK
HOLE
There are two main process constantly
going on in massive in stars: nuclear
fusion and gravitation. These two
dominates, the stars to collapse.
Once the star starts to collapse, it does not
stop, and the star will come inward upon
itself, resulting in the formation of a black
hole.
Only those stars greater than 3 times the
mass of sun that become Black Hole upon
collapse.
6. IF WE CAN’T SEE THEM, THEN HOW DO WE
KNOW THEY ARE THERE?
The X-rays are sent off into space and when they
strike the matter around the black hole , it can be
detected.
Binary X-ray sources are placed to find strong black
hole .
Another sign of the presence of a black hole is random
variation of emitted X-rays. And gravitational
lensing ,accretion disks n gas jets .
9. continue……………
Black hole weigh about as much as a star . It
would be aprox 10 times mass of sun .
More massive , more space it would require .
The size and mass have a simple relationship,
which is independent of rotation. According to
this mass/size criterion then, black holes are
commonly classified as :
Supermassive black hole
Inter-mediate mass black hole
Stellar-mass black hole
Micro black hole
10. HOW BIG IS A BLACK
HOLE?
Black holes weigh about as much as a massive
star. A typical mass for such a black hole would
be about 10 times the mass of the sun.
The more massive a black hole is, the more
space it takes up. A typical 10-solar-mass black
hole would have a radius of 30 kilometers, and
a million-solar-mass black hole at the center of
a galaxy would have a radius of 3 million
kilometers.
12. FALLING INTO A BLACK
HOLE
A black hole is a place where the force of gravity is so
powerful that you would need to be travel at a speed faster
than the speed of light to escape its pull. Since nothing in
the universe is faster than the speed of light, nothing that
falls into a black hole can ever escape.
The pulling force would increase as you moved toward the
center, creating what's called a "tidal force" on your body.
If you fell into a large enough black hole, no one outside
would be able to see you, but you'd have a view of them.
Meanwhile, the gravitational pull would bend the light
weirdly and distort your last moments of vision.
13. IF A BLACK HOLE EXISTED, WOULD
IT SUCK UP ALL THE MATTER IN THE
UNIVERSE?
A black hole has a horizon," which means a
region from which you can't escape. As long
asyou stay outside of the horizon, you can
avoid getting sucked in .
15. SUN AS A BLACK HOLE
Only stars that weigh considerably more
than the Sun end their lives as black holes.
The Sun is going to stay roughly the way it
is for another five billion years or so.
If the Sun *did* become a black hole for
some reason? The main effect is that it
would get very dark and very cold around
here. The Earth and the other planets would
not get sucked into the black hole; they
would keep on orbiting in exactly the same
paths they follow right now.
17. HUBBLE BLACK HOLE PHOTO
The strikingly geometric disk --
which contains enough mass to
make 100,000 stars like our Sun --
was first identified in Hubble
observations made in 1992.
18. BLACK HOLE SEEN IN CLOSEST
LOOK EVER
September 4, 2008—A super massive
black hole at the center of the Milky Way
has wound up in the crosshairs of a
virtual telescope spanning 2,800 miles
(4,506 kilometers).
Though unproven, there is strong
evidence for the existence of black holes.
20. NASA create a
three-dimensional
simulation of
merging black
holes. This was the
largest
astrophysical
calculation ever
performed on a
NASA
supercomputer.
