Looking at this photo, I mean it is beautiful, but we can’t wrap our head around the maddening violence of space. It’s so hostile to life, and earth has us biased towards a peaceful outlook, but space is maddeningly violent and inhospitable. Imagine approaching a black hole and being spaghettified a great distance across where you have to endure many years of physical & mental torture before being destroyed at the event horizon?!

This actually just gave me a super dark thought, I do wonder if any "life" has experienced being pulled into a black hole over the last few billion years.

  Yeah I mean time breaks down and you experience everything in slow motion and are stuck circling a black hole for what seems like an eternity. It’s unlikely to happen to anyone here on Earth, but you are right, there’s the likelihood of other life getting stuck in these things.

  Depends on your solution to the Drake equation. But unless you think life is universally unique to earth, I’d say it’s quite likely. The universe is big, if there’s any more life, there’s a lot of it, and models predict there are lots of black holes out there in every galaxy.

  Is there any evidence for time dilation though? My 1000 years number is a rough guess, and it could be shorter or even longer than that. I was thinking since physics breaks down that you would have to endure being spaghettified whilst still being able to feel and have nerves intact and thinking capacity.

    Relativity means time slows down for an observer, not for the observed. You would see the universe around you rapidly speed up and eventually die.

For an outside observer it might seem like a long time, but not for you.

  Even if your brain is perceiving time normally, even if you’re not experiencing enough acceleration to be crushed yet, I really don’t want to think about the effects of a severe time-dilation gradient on the rest of the body.

    You would have been cooked by x-rays before that happened.

According to this video, the spaghettification doesn't happen until the last few seconds/minutes, when you're close to the singularity. https://www.youtube.com/watch?v=4rTv9wvvat8 https://www.youtube.com/watch?v=4rTv9wvvat8
