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?

So, I can freely move through time if I consider alcohol as my time machine.

Freely means both directions, not just different speeds in one direction.

You move through time every second…
Donjamos@lemmy.world 2 months ago
Walk in the other direction then, let’s see how that goes.

That not how you do it. Watch a documentary called edge of all we know. Someone much smarter then you has that opinion.
