Could a human enter a black hole to study it?

Matthew McConaughey already did

Yes.

But they won't be able to report their findings.

What kind of black hole are we dealing with?

This sounds like a good Keeping up with Kardashian’s episode.

Sure you could enter it. Could you exit it is the question

If the Kardashians let black science guy write an episode where they explain astrophysics to people it might actually be a decent episode and would probably be the most educational thing anyone who’s ever watched it has experienced. They could use the mass of Kim’s arse to explain the relationship between mass and gravity, her brain to describe the vacuum of space, and her mom as an example of a black hole.

Take a mechanical clock with rotating hands (hours, minutes, seconds) and gradually move it closer to a black hole.

1. At a sufficient distance, the hands rotate around the clock at more or less “normal” rates.

2. As you move it closer and closer to a black hole, the rotation of the hands seem to slow down to an observer standing at the original position.

3. As the clock approaches the event horizon, the rate of the clock slowing down approaches infinity.

4. Finally, at the event horizon, the clock appears to stop working completely to an observer standing at the original position. It will now take an infinite amount of time for the second hand to move one second.

It’s called gravitational time dilation.

Edit:

Now, here’s the kicker. Spaghettification occurs due to different tidal forces exerted on your body (if you were to dive into the black hole feet first). Your feet will be pulled at a greater rate than your head, stretching you out. But as your feet are also closer to the singularity, from your head’s perspective, this stretching is taking an eternity to progress.

Isn’t that what Prince Harry is doing?
