No Stupid Questions

I suppose it depends on what shape you already have in the 4th dimension.

If you or the current 3d space don't already occupy any length in the 4th dimension, then you'd simply disappear from the world, or from your point of view, the world around you would disappear. Just like a cutout stick figure on a piece of paper.

Now, you can obviously move a flat piece of paper upwards without destroying the drawing, so if your friend is kind enough to include your surroundings in the dimensional shifting, then you'd be fine. Fly around the 4th dimension in your bedroom or whatever.

Hate to break it to you. But you are moving through time. Every second.

Without time, if you weren’t moving through time, nothing could change, and the rate time flows is different for each of us… it’s complicated and I’m far from the best person to explain it, but time is not like a fourth axis that everything gets placed on, even if that’s kinda sorta how we model it.

I think you’d immediately collapse into a shrivelled-up ball of super-dense matter.

The Pauli exclusion principle keeps particles like electrons from occupying the same physical space, which is what makes them take up volume and gives atoms and molecules their size. If they were free to move in an extra spatial dimension, they could pack much closer together, and their volume would collapse.

we are talking a 4th spacial dimension and not time yeah?

Would moving/shifting in the 4th (spacial) dimension be fatal?

You would disappear immediately. That's all. Noone of us would have a way of knowing if you're still alive or not, so it makes no difference :)

(Usually we call time the 4th dimension, but you want to use a 4th spatial dimension, which isn't even defined in physics, only in math)

the question is, is the spacetime over "there" compatible with your form of experiencing life? who the fuck knows, tell us if you make the journey and come back, we'll wait and cheer you on :3

Well, that would depend on what's in the other 3D "layers" of the 4D world. Like how 3D worlds can be thought of as layers of 2D ones. If you moved to another 3D "layer" that had no oxygen, food, water, etc., you would quickly die. If you moved quick enough you would also probably die, but the same could be said about the three spatial dimensions we're used to. Also, if there was a fourth spatial dimension, it must be "compact" enough that we can't detect it with our current technology, and I have a hunch (!!! no evidence for this, please search for some if you want good facts!!!) it would be bad for us to move through it.

I move through the fourth dimension constantly? It tends to be a continuous thing though, just like the other three.

Now adjusting the fifth and higher via the Higgs field could get a bit trickier, as you’d have to be VERY precise about what went where to avoid annihilation. Each dimension you add increases by a power of magnitude what the coherence calculations would be.

Depends on if existence in this level of 4D is dependent on being at this level. Using your 2D in 3D example (aka Flatland) what if the 2D plane is at sea level pressure, but changing the Z axis there is a different pressure (as we understand, but the shapes would not), to the point where Mr. Square dies if we lift him too far up.

Now imagine a 4D version, where it's not air pressure, but something more fundamental about physics changes if we're moved from our current 4D state. The idea being that space as we understand it is 3D, but perhaps exists as part of higher dimensions along with other universes. But they could be completely different, and movement from ours to theirs by just sliding in 4D would change the "space" we're in, in a bad way.

Or we could just wink out of this 3D space, but be in just a different state and be fine, seeing a weird cross section of what we're used to.

this isn't really a useful question, it's wholly hypothetical so we can't know.

It's like all those paradoxes: They're paradoxes because they're not realistic situations, so there is no answer.

If you like ideas like this I highly recommend flatland by Edwin A. Abbott.

Part one is a lot of social and religious critiques of the time it was written (1884 for second edition). Part two covers a lot more of the questions you brought up.

Warning: it is a work of fiction. Don't expect hard science but my understanding is a lot of the ideas expressed here match modern math ideas.

It depends on what is along the 4th dimension.

Assuming you mean moving in a different way than we already are, it probably just depends how. Same as with the other 3.

If you move forward 100 metres at 100,000 mph, you arrive in a paste. If you take a vortex approach to movement, paste again.

So how were you planning on moving along the 4th dimension?
