If you were to throw a person into a black hole, would you actually see him cross the event horizon? Explain.?

Answer 1

The event horizon is place at which you can see light (people?) entering but you cannot see anything beyond that. Maybe it's 1cm wide. Maybe it's much less. Maybe it's variable. In any case, you cannot see *ANYTHING* that happens beyond the event horizon.

Therefore, if you tossed someone toward a black hole, that person would hit the event horizon on the way in. If you had a fast enough camera you could take pictures of the person traveling through the thing.

You'd be taking pictures and taking pictures and--suddenly--you'd take a picture which showed everything from their shoes up to half their head. The other half would have crossed over the event horizon. It would be gone.

Another picture might show the person from shoes to shoulders but everything further on would be gone as if it never existed. No blood. No gore. Just part of the person, the part still on your side of the event horizon.

Another might show them from shoes to waist, then to their knees, then just the soles of their shoes.

In the next photo, that person would be gone.

Gone. As if they never existed. Gone into a black hole, a singularity where gravity is so massive that not even light can escape.

If you think all that means being able to actually see the person cross the event horizon, then yes, you can see it happen.

We need more and better science to test the theory, though.

Answer 2

No. You'd see him enter, but light from beyond the event horizon can't get back out.

Answer 3

Yes. I can't explain it but it happened to Homer Simpson.
