I have a theory on the way things may look from a 4 dimensional perspective.
It is vague & may be totally off, but i feel it is a good representation.

We are not able to percieve things from a 4-dimensional perspective, take a look at a hypercube & you'll see what i mean. It's like a drawing trying to percieve things in 3-d.

The thought just occured to me while looking at a barcode.
If you were to be able to see things from a 4-dimensional point of view, our world may look somewhat like a barcode (the ones with all the little dots not just plain bars).
To us, it means something & is one single whole unit.
But to something which can percieve a 4th dimension, i believe our world would look just like the aforementioned barcode.
Lots of empty space with little segments floating freely at different depths. I guess similar to the way we see things when we look at a 3-d model of outerspace.
