What makes black holes "black" and white holes "white" ?
Not quite, it means that light speed is slower than the escape velocity caused by gravity. Gravity is also radiating at the speed of light.Hello
"Black holes" so called because the light that goes through it has a lower speed than the gravitational force of black holes that's why light can't get out of it, and we can't see it, so these holes called "black."
About the "white hole", as I know, the scientists they have not yet found, but according to the law of conservation of energy, this energy that enters a black hole should get out of the white hole, and if the light is in a black hole can not escape, the white hole It acts with a repulsive force, and we see a bright light that's why "white holes" so called.
I hope I could help you.
Yes, I had that in mind but incorrectly expressedNot quite, it means that light speed is slower than the escape velocity caused by gravity. Gravity is also radiating at the speed of light
Some footnotes from WikipediaBlack holes and white holes are not related. Energy going into a black hole simply gets stuck there and then radiated away as Hawking radiation. Black holes are not wormholes to white holes, they are simply inescapable gravity pits.
What makes you think it "keeps" drawing it deeper? It draws it to the center and that's it. Black holes are finite.If a black hole draws in everything within it's event horizon, and keeps drawing it deeper, does that mean the black hole is infinite?
I know that.I am asking that without knowing the end how we can conclude blackhole is finite???The singularity is simply where the math breaks down and produces nonsense results.
It is NOT a description of a physical object.
We DON'T KNOW what physically is going on at the center of a back hole.
We do know that the infalling stuff is by this time no longer in the form of atoms, because atoms disintegrate before that point.
Neutron stars, (very massive objects which are not quite massive enough to be black holes), are known to exist by observation, and what we observe IS consistent with GR math.
The star has become mainly a soup of neutrons with other subatomic fragments mixed in.
Well strictly speaking we can't make any conclusions at all since we can't observe anything, we can't reproduce the conditions, and the best theory we so far have; GR, doesn't make sensible predictions.... without knowing the end how we can conclude blackhole is finite???
This is an illogical statement. Complete and infinite do not mean the same thing. For example: a set of all positive integers is an infinite set, but does not contain all numbers.We do know that stuff (like us) exists externally to the black hole though, so in that sense it can't be infinite.
That's mostly the theories I've read about, Praveena. I wonder why no one has ever tried to send a camera of some sort inside a black hole to actually see what happens before (or if) it's destroyed? Until we actually know what's inside, everything we say is nothing more than conjecture or speculation at this point.How you are saying that blackhole is finite?Is that singularity is the end??
