It will just get sucked in and pulled to another part of the
Universe. It will supposedly take you to another place of the
universe in FAST time.
You would explode from the lack of atmosphere, then your remains
would be crushed into a microscopic size.
the super gravitational pressures would compress you.
unsure of a good way to answer this, but as the nuclear fuel is expended, the star gets denser, until it "implodes" further yet.
the gravitational pull is so strong that the light cannot escape, and is pulled back inside. Since no light emits, there is "nothing " to see.
