OT: No black holes? One scientist thinks so...

Greetings,

A hole does not exists by itself. It is what is around the hole that exists...

Thank you

Black holes aren't really holes...

I've also heard them called "Frozen Stars" because the intense gravity changes time inside, to the extent that - from an outsider's perspective - they never fully collapse, just slow down and stop. They're still in the process of implosion, so the end result of a collapsing star is irrelevant to the known universe, since such a thing cannot occur in a finite (external) timeframe.

If you flew into a black hole, you might see the end result of the collapse, but then the information would never get back out The end result is that there are no singularities in the universe, and the mass component of black holes ends up having finite size as far as outsiders are concerned.

Another result is that you can't kill people by throwing them into black holes, unless you also die (assuming the BH is big enough so that tidal forces at the event horizon are weak). You can throw someone in, visit them 10 years later, and they'll still be alive as though no time has passed. Of course, you won't be able to leave once you visit them, and then you'll both die.
