Is a three-dimensional object possible? Not really. A three dimensional cube would have width, depth, and height, but no duration. It wouldn't exist for any lenght of time. All objects need to have a measurable extension along the fourth dimension in order to exist for more than zero time.

That's how I think of it, anyway. Just because humans don't have the ability to freely move along the fourth dimension doesn't mean that nothing does. I once read an article that explained how tachyons have been observed to move in a non-linear fashion along the fourth dimension.

It's just a skill that we don't have.

Honestly, I'm not sure that I can. I'm not a physicist, or even close. I didn't entirely understand the article that I read, and everything else I wrote in that post could easily be a missaprehension.

How ya doing, buddy?

According to my understanding, Einstein disagrees. However, I'll not press the point, since I am by no means sure of my grounds.

This thing is sticky, and I don't like it. I don't appreciate it.
