Human comprehension seems to be painfully limited most of the time.

I've been thinking now, you know how we divide time? This seems rather arbitrary. Time does not come bundled up into little packets, so the only thing we have to compare time to is our units of time.
Mathematicians think of time as a fourth dimension, one that we always move along, but not always at the same speed. If you move in a space ship at near the speed of light, then you fly to a star and back in 20 years, you may have only aged 2 years compared to your friend on Earth whom aged 20.
How do you really define time?
We cannot comprehend it.

I've been wondering also, about our system of math.
We have numbers, and variables, and shapes, and all that good stuff.
But, what if there was a different system of math, just beyond our comprehension? One that didn't use numbers? One where it was possible to divide a circle into 7 parts? To rationalize pi?
If asked why our math is the way it is, I would just say that that's the way math just is.
If aliens evolved on another planet, would they come up with math that DOESN'T use numbers and shapes?

And, have you ever heard of string theory? That says that all matter is made of tiny vibrating strings of energy, that these tiny strings move in 11 dimensions, and that all these strings are attatched to membranes that hold our entire universe.
And apparently there might be parallel universes literally INCHES away. But they're on a different membrane, and all of OUR strings are connected to our membrane.
Such science as this, along with dark energy, (the supposed explanation for why the universe is still expanding and supposedly over 70% the mass of the universe) sometimes makes me think scientists get their new science directly out of their assholes.
And if that's where they get it, I suggest they just shove it right back in there.
