Astrophysicist here. Yes, space is crazy, but interesting things to keep in mind:

  1. The size of a star is determined by something called the photosphere. With those extremely massive stars, you can be hundreds of millions of kilometres "inside" and not yet know it.
  2. Similar story with supermassive black holes, from the perspective of an astronaut falling in, they wouldn't really be able to tell when they cross the horizon because the tidal forces there are very small (they will inevitably fall towards the centre and get spaghettified at some point)

:0 how can you be inside a star and not know it? I thought they all had a surface like our Sun

second question, would you even feel the spaghettification? Would the signals from nerves be able to travell up to the brain?

Right? How can you not know it?

Hmm, am I in the star yet? I mean my body is now made of million degree hot plasma, but I'm still not sure....
