What would happen if an astronaut went into a black hole?
Of course, no matter what type of black hole you fall into, you’re ultimately going to get torn apart by the extreme gravity. No material, especially fleshy human bodies, could survive intact. So once you pass beyond the edge of the event horizon, you’re done. There’s no getting out.
What goes on inside a black hole?
A black hole is a tremendous amount of matter crammed into a very small — in fact, zero — amount of space. The result is a powerful gravitational pull, from which not even light can escape — and, therefore, we have no information or insight as to what life is like inside.
Have we sent anything into a black hole?
Fortunately, this has never happened to anyone — black holes are too far away to pull in any matter from our solar system. But scientists have observed black holes ripping stars apart, a process that releases a tremendous amount of energy.
Are black holes scary?
These black holes are dark most of the time, but when their gravity pulls in nearby stars and gas, they flare into intense activity and pump out a huge amount of radiation. Massive black holes are dangerous in two ways. If you get too close, the enormous gravity will suck you in.
How long until the Milky Way dies?
New simulations reveal their ultimate fate. The galaxies will coalesce into one giant elliptical galaxy — dubbed “Milkomeda” — in about 10 billion years.
What will happen when all the stars die?
100 billion years from now: All sun-like stars are dead At that point it’ll become a fading and dying white dwarf, incapable of nuclear fusion and hosting life on planets around it. That is when we’ll have to move to another sun-like star if we want to survive.
What Year Will life end?
With the extinction of life, 2.8 billion years from now it is also expected that Earth biosignatures will disappear, to be replaced by signatures caused by non-biological processes.
How long will the universe live?
200 billion years
