Touch the untouchable, break the unbreakable

Here’s a bit of a sciencey post!

So we all know we live in three-dimensional space. We can go up and down, left and right, forwards and backwards. Pretty easy, right? But then what four-dimensional space? What extra direction is there to add? Let’s take a step back and look at two-dimensional space first.

In two-dimensional space, you can only move in two directions. Up, down, left and right. There is no such thing as depths, and the flatlanders (inhabitants of such a dimension) are as puzzled about a third dimension as we are about a fourth. Take the old Mario games for example. You can tell the ol’ plumber to go left or right, jump up or fall down. He has no problem with that, that’s just his day-to-day business. However, ask him to move “forward” or “backward”, and he’ll think you’ve gone mad. It’s impossible for Mario to imagine a third dimension of movement, since he’s been living in two dimensions all his life.

The problem scientists are having with the fourth dimension is almost identical. We have no idea of knowing what the fourth dimension could be like, for we can not perceive it, or it may not even be in our space. Sure we can theorize the everliving snot out of it, but it’s very unlikely we’ll ever find a definitive answer. It is pretty cool to think about it though… If two-dimensional space has squares, and three-dimensional space has cubes, what does four-dimensional space have? (Hint: it’s hypercubes.)

And boy we haven’t even touched the other dimensions yet! If you’re interested in learning more, check out Imagining the Tenth Dimension, parts one and two. It’s still all pretty vague to me, but very interesting nonetheless!

Physics can be so cool sometimes!

    I was under the impression the fourth dimension is time. This is possibly the shittiest comment I’ve ever left.

    Carl Sagan had a series of videos explaining stuff like this. I have a better understanding of the 4th dimension now. :P
