“In a black hole” ... maybe you mean you’ve already crossed the point of no return but not yet hit the singularity...

Eh, forgive me but also, an outside observer would say it takes an infinite amount of time for you to hit the event horizon, (and get smeared and red-shifted to nothing on it), but the in-falling frame of reference passes through the horizon as quick as any other point.

Now is the entire universe a black hole in some sense? Perhaps, but in pondering such a case I find it is no more terrifying, majestic, mysterious, and awe inspiring when contemplated that way than any other.

Why would that be frightening? Everything we care about and can observe is obviously inside the black hole with us. Being inside a black hole wouldn't change the price of bread.

You should be able to observe the outside of the event horizon from the inside.

How could we not know? Our own light would hurdle towards the singularity, let alone our mass.

I had the same thought a few weeks ago. Super unsettling.

It also made me wonder, if the center of a black hole is blindingly white, what if that’s where our souls are pulled to when we die?

How is it white, no light is able to go in direction from the center even after crossing event horizon (if that even possible to do mantaining ability to observe anything)

If you're in a space ship and you pass the event horizon- well, what passing the event horizon means is that your light cone has tilted such that the centre of the black hole is in your future, not some distance away in space. So from your point of view, it isn't that there's a direction in space light can't come from- you can potentially see things in all directions- it's just that your definition of space and time have changed such that the singularity isn't 1 kilometer away, it's 20 minutes away. But otherwise (ignoring your destruction due to growing tidal forces) things on your spaceships work normally-ish.

isn’t it equally as likely our souls float up a dog’s butt or something
