I was curious, please explain to me in an easy way of understanding because I am not the best at picking things up. Thank you.

Yes, but then he was refuted sometime in the early decade of 2000. I want to know how he was refuted.

I do not think information is conserved in a black hole. They do radiate, but this radiation is random.zeromodz said:I was curious, please explain to me in an easy way of understanding because I am not the best at picking things up. Thank you.
Passionflower said:Chronos, do you understand the difference between information and random radiation?
For instance assume an astronaut falls into a fully formed black hole. All the information about him, his length, the color of his eyes, the number of atoms in his body etc will be destroyed in finite time after he passes the event horizon. All that will ever be returned about him is random radiation.

Chronos said:Hopefully I do, passionflower. Black holes eventually [very eventually] evaporate via Hawking radiation. Hence, any 'missing' information is ultimately returned to the universe [albeit mangled] via the combination of Hawking radiation and the final 'poof' when the black hole finally evaporates. It all hinges on how you define 'information'. Many scientists would characterize information loss as a form of entropy. I'm ok with that.
The idea of information conservation in black holes is known as the "black hole information paradox." It refers to the question of what happens to the information of matter that falls into a black hole. According to the laws of physics, information cannot be destroyed, so it must be conserved in some way.
The conservation of information is essential because it is a fundamental principle in physics. It also has implications for our understanding of the universe and how it works. If information is not conserved in black holes, it could lead to a contradiction in our current understanding of physics.
Hawking radiation is a phenomenon proposed by physicist Stephen Hawking, which suggests that black holes emit particles over time and eventually evaporate completely. This process is thought to conserve information, as the particles that are emitted contain some information about the matter that fell into the black hole.
This is still a subject of debate and ongoing research in the scientific community. Some theories, such as the holographic principle, propose that information is not actually lost in black holes but is stored in a different form. However, the exact mechanism of how information is conserved in black holes is still not fully understood.
As of now, there is no known way to retrieve information from a black hole. The intense gravitational pull and the event horizon make it challenging for any information to escape. However, with further advancements in technology and theoretical understanding, it may be possible to retrieve information from black holes in the future.
