For all scientific reasons, no astronaut had went inside a black hole. It would take many earth years to visit the black hole, so reaching a black hole is impossible.
no one knows
No one has ever visited a black hole.
Most astronauts are a lot more careful than that. Nevertheless, if that were to happen, the gravitational pull of the black hole would either suck them in, never to be seen again, or else rip them apart.
no
No, no astronauts have disappeared into a black hole. Black holes are objects in space with such strong gravitational pull that not even light can escape from them. Human space exploration has not led to any incidents involving black holes.
No
The black hole nearest to our Earth is (fortunately) several thousand light years away. No human has been farther from our Earth than our Moon. Thus, we are technologically quite a ways away from being able to travel to a black hole.
Astronauts didn't discover black holes....
A Schwarzschild black hole is a non-rotating black hole. The Kerr black hole is a rotating black hole. Since the latter is more complicated to describe, it was developed much later.A Schwarzschild black hole is a non-rotating black hole. The Kerr black hole is a rotating black hole.

The space needle is used for making a hole in the fabric of the space-time continuum, therefore creating a black hole and destroying us all.
Yes, astronauts can visit the moon at any phase of the lunar cycle. The visibility of the moon's surface features may vary depending on the phase, but this does not prevent astronauts from landing or exploring the moon.
