Is a black hole smaller than an atom?
Despite having roughly the mass of a thousand sedans, a mini black hole would be smaller than an atom. At that size the black hole wouldn’t swallow much matter and would instead mostly trap atoms and some larger molecules into circling orbits—in much the same way that protons in atoms capture and bind electrons.
Can an atom survive a black hole?
It is possible that this Universe is the inside of black holes in a container Universe. If that is more-or-less correct, what we see at our own beginning, is that no structures larger than hydrogen atoms survived the infall. So, there is no atoms not only in black hole but even near.
How does time stop in a black hole?
Near a black hole, the slowing of time is extreme. From the viewpoint of an observer outside the black hole, time stops. Inside the black hole, the flow of time itself draws falling objects into the center of the black hole. No force in the universe can stop this fall, any more than we can stop the flow of time.
Can a singularity explode?
The Quantum Bounce Rovelli and his collaborators speculate that these quantum gravity effects not only prevent the singularity from forming, but may in fact cause the black hole to explode. But this will only happen when quantum gravity dominates–i.e., when the matter is so compact that it’s almost a singularity.
What happens inside a singularity?
In the center of a black hole is a gravitational singularity, a one-dimensional point which contains a huge mass in an infinitely small space, where density and gravity become infinite and space-time curves infinitely, and where the laws of physics as we know them cease to operate.
Why would a singularity explode?
The initial singularity was the gravitational singularity of infinite density thought to have contained all of the mass and space-time of the Universe before quantum fluctuations caused it to rapidly explode in the Big Bang and subsequent inflation, creating the present-day Universe.
