Has anyone here ever actually tried to prove (analytically) that space is three dimensional? I've never seen a good proof. Here is my basic idea behind a proof:(adsbygoogle = window.adsbygoogle || []).push({});

Let us proceed as if we know what an infinite straight line is.

Consider two infinite straight lines that have one point in common, point X. There will be four vertical angles formed. If they are all equal, each of them is a right angle, and the two lines are perpendicular.

Now, consider the following question.

How many more infinite straight lines can pass through point X, such that all vertical angles formed are right angles.

Let us define thedimensionality of spaceto be the maximum number of infinite straight lines that can meet at a point, such that all the lines are mutually perpendicular.

I put this in the SR thread, because I didn't really know where else to put it, so change the location if you want.
