To oversimplify, "information" is a very specific thing in quantum physics. Classical physics has the rule that energy can change form but cannot either be created or destroyed.

Information works the same way in quantum physics, which makes black holes seem like a problem since their event horizons are inescapable and anything that falls inside is lost.

Thanks, your explanation is interesting and makes sense at my level of abstraction.

Eventually i would like it, if some physicist could come up with a cosmology where energy could be created and entropy of a close system could decrease ... in specific conditions and in our present day universe.

Also, in my naive understanding, chaotic pendulums creates information.

My buddy is a PhD candidate and he's heavily involved in black hole research, I'm not even going to try to summarize it because when he talks to me it's like me watching a finger puppet play.

One of the things he talks about is how The jury is still out on if energy is even real.

(...) if energy is even real.
