Comment on well?
atomicbocks@sh.itjust.works 7 hours agoOn the contrary; while I have heard the explanation that the commenter you replied to has said I have also heard a slightly different theory:
Our universe is the 3 dimensional event horizon of a 4th dimensional black hole. By extension we may find that black holes in our universe have similar funky 2 dimensional areas at their even horizons.
I am sure clickbait articles are part of it but there also seems to be several actual theories surrounding the idea of the nature of our universe relating to black holes.

Our universe is 4 d not 3 d

Nah, this universe is 3d.
I’m assuming you are thinking that time is the 4th dimension and we have time here so we are 4d?
Time may be the 4th dimension, but in our universe, time doesn’t actually behave like a proper dimension. For one thing, dimensions should be spatially perpendicular to each other and time is not. We also seem to only be able to move one way through time whereas we can move back and forth through the other 3 dimensions.
Dimensions get weird and complicated. For the intents and purposes of this conversation it’s correct to say that the universe were experiencing now is 3 dimensional.

3+1, not 4D (we cannot move freely in time). They’re referencing the holographic universe theory, or holographic principle. PBS Spacetime has a good episode on the holographic universe theory.

YOU can’t move freely in time. Don’t speak for me.
Ok, I can’t either. But still…

I think I can move freely in time, just not voluntarily…
Sometimes I go through a whole day in like a minute, sometimes I blink and it’s Monday already.
Or maybe it’s working nights has that effect?

Yes, but if you’re beyond the event horizon time becomes basically* irrelevant. You could literally turn around, look back out towards the rest of he universe, and watch all of time play out in the blink of an eye.
You know that scene in Interstellar where they land on the planet for 5 minutes, but 20 years passes for everyone else due to the planet’s mass? It’s the same thing, but a billion-billion-billion times more severe.

Do you have any idea how little that narrows things down?
