Very unlikely. Though it is possible that Earth will fall into a black hole in the very distant future. There's a theory that it will be kicked out of the solar system eventually, which might lead to Earth falling into the black hole at the center of our universe.
You can't see the light because it's not passing through the black hole at all - the singularity of a black hole is so dense that no matter, not even light, can escape. It's (probably) all crushed into the singularity.
The singularity of a black hole is an infinitely dense point where gravity is infinite and spacetime warps, and the laws of physics as we know it cease to operate.
The power of the singularity comes from its infinite gravity, warping space and time. There are still mysteries surrounding aspects of black holes, such as the jets that are sometimes shot out from them, probably originating in the accretion disk. There have been theories that we could somehow harness black holes to produce large amounts of energy, somehow.
Singularities are infinitely small, no matter what you compare them to. The masses of black holes vary, and the radius of a black hole's event horizon changes depending on the mass of the black hole.
What are the chances of Earth falling into a blackhole?

ReplyDeleteWhy can't you see the light that passes through a black hole?
ReplyDeleteYou can't see the light because it's not passing through the black hole at all - the singularity of a black hole is so dense that no matter, not even light, can escape. It's (probably) all crushed into the singularity.
DeleteWhat do you mean by "space and time have no meaning" when referencing the singularity of a black hole?
ReplyDeleteThe singularity of a black hole is an infinitely dense point where gravity is infinite and spacetime warps, and the laws of physics as we know it cease to operate.
Deleteis there an estimated number of supermassive black holes in our universe?
ReplyDeleteThe universe is infinite, so that would be impossible to answer. There's an estimated 100 million black holes in our own galaxy, however.
DeleteWhere does a black hole's energy and power come from?

DeleteIn comparison to the event horizon how large is the singularity ?
ReplyDeleteSingularities are infinitely small, no matter what you compare them to. The masses of black holes vary, and the radius of a black hole's event horizon changes depending on the mass of the black hole.

ReplyDeleteWho first discovered black holes?
ReplyDeleteAlbert Einstein was the first to predict black holes, in 1916, but Charles Thomas Bolton was the first to physically discover one, in 1971.
DeleteWhat do you mean by what a black hole "would like to be"?
ReplyDeleteI actually said "what they like to eat" - referring to gas, stars, light, and anything else that reaches the event horizon.
