4th dimension

Ideas about how a world with more than three spatial dimensions would work - what laws of physics would be needed, how things would be built, how people would do things and so on.

4th dimension

is there really a fourth dimension? and if there was, how could a 3 dimensional being get there?

is there really a fourth dimension

This is the most commonly asked question on this forum, and also the dumbest. If people knew whether or not there was, don't you think it would be a big deal? Wouldn't it be one of those types of things that you learn in kindergarten or something, along with E=mc^2, or that we are part of a solar system?

and if there was, how could a 3 dimensional being get there?


Force would need to be applied perpendicular to the 3d being, sufficient enough to break the boundaries of the Universe as we know it.

But if the forces were applied perpendicular to a 3d thing or person, then wouldn't it do nothing to the person because it would just miss the 3d object/thing/person.

I'm not sure what your saying here. Imagine a piece of paper, and you draw a triangle on it. If you push against it, it will fall out into 3d. You have to make sure not to touch his insides, however, those can be mushy ;)

You would have to score the shape, not just draw it... :|

But then how could you push the triangle? Wouldn't your hand just go over it because your hand is 3d but the triangle is 2d?

Well, try it yourself, score out a triangle on a piece of paper. If you push it hard enough, it'll remove itself from the rest of the paper.

The person is just as real as you or I; it's just flattened 3 dimensionally.

This is kinda idiot, no offence. The paper and the drawn triangle are 3D and your comment irrevelant.
