Comments by "Delibro" (@Delibro) on "Falling Into a Black Hole (Simulation)" video.
Yea but if you are near the black hole, time dilation gets exorbitant strong, thus you see the outside universes time elapsing quicker and quicker, until millions of years are a fraction of a second. Then, Hawking Radiation happens so quickly that the black hole vaporizes before you reach it. So, you never reach a black hole.

@wulfheort8021 No one said that. Time slows down at you but keeps moving normally on earth - thus you see all speeding up on earth.

Yes you would see that. But as you get nearer to the black hole you would see it quicker and quicker in a matter of seconds. The sun would become a red giant, engulfing the earth, then fading ... all stars fading ... the universe ends ...

@wulfheort8021 Simon and me are talking about photons from the earth being received at a quicker rate, not slower. There are three things we need to consider: time dilation from speed approaching a black hole, time dilation from gravity near a black hole and the direction of your speed relative to the earth. Time dilation from speed and gravity means your time ticks slow, but of cause you always perceive it as normal. Photons from the earth reach you clinched, so you see things as if they are sped up on the earth. Third thing is your trajectory relative to the earth while approaching a black hole, if you depart the earth you will see things on the earth like slowed down, if you approach, like sped up, but I think this is minor compared to the first two things.

@wulfheort8021 As I've said, no one claimed that the earths time would sped up, Simon and me had always said "one would see...". As its true below the event horizon that you see only certain things, above the event horizon you would see landmasses collide. You don't try to understand, you nicpic on little pieces and you depart from the topic.

@DakumunDahBat Yea, but time dilation gets stronger the closer you get to the event horizon - exponentially stronger. Ultimately, from your perspective, also a septillion years will pass in the outside universe, causing every black hole to Hawking evaporate. To phrase it another way: The closer you get to the event horizon, the more time dilation, the quicker Hawking radiation happens, the more the event horizon pulls back from you.
