> Honestly what confuses me is what special distinction does time get to make it not considered a dimension like the others?

My less-than-a-layman understanding is that it really is just a physical point/plane - but as 3-dimensional creatures it will appear to us as time.

Sagan's flatland video shows the 3-d apple moving through 2-dimensional as transitory slices; the 2-d creatures don't see the entire apple because they are fine tuned for 2-d existence.

Interesting, but this seems to contradict(?) the fact that there are 4+ spatial dimensions.

This reminds me of passage in a book or movie (can't remember which one) which talked about the idea of human beings in 4D as worms, with the tail of the worm being the baby, and the face being our current state. As we go through life we keep elongating the work and overlap ourselves in space.

There’s a Heinlein short story with a similar passage. It’s in a compendium of stories called The Man Who Sold The Moon.
