Black holes provide theoreticians with an important theoretical laboratory to test ideas. Conditions within a black hole are so extreme, that by analyzing aspects of black holes we see space and time in an exotic environment, one that has shed important, and sometimes perplexing, new light on their fundamental nature.
Black holes are pretty scary when you ponder them. They seem nihilistic, infinitely destructive on an inconceivable scale, notwithstanding the ideas of Hawking radiation.
It's hard to know which stars in the sky will turn into black holes. And which ones will open up worm holes into entire new universes.
Black holes can bang against space-time as mallets on a drum and have a very characteristic song.
I like science fiction and physics, things like that. Planets being sucked into black holes, and the various vortexes that create possibility, and what happens on the other side of the black hole. To me it's the microcosmic study of the macrocosmic universe in man, and that's why I'm attracted to it.
General relativity predicts that time ends inside black holes because the gravitational collapse squeezes matter to infinite density.
Evolutionary cosmology formulates theories in which a universe is capable of giving rise to and generating future universes out of itself, within black holes or whatever.
The black holes of nature are the most perfect macroscopic objects there are in the universe: the only elements in their construction are our concepts of space and time.
It is no good getting furious if you get stuck. What I do is keep thinking about the problem but work on something else. Sometimes it is years before I see the way forward. In the case of information loss and black holes, it was 29 years.
Black holes, we all know, are these regions where if an object falls in, it can't get out, but the puzzle that many struggled with over the decades is, what happens to the information that an object contains when it falls into a black hole. Is it simply lost?
