You need to read some theoretical physics before you start asking those questions, colonel. Our current technology detects nowhere near the Planck distance. That length is a result from quantum physics, and I believe it is related to the uncertainty principle but it's been a while since I've looked over that stuff. As for where it came from, when the Big Bang occurred certain physical constants were 'frozen' into the spacetime continuum. The most famous is probably c = speed of light. I won't even try to provide details since there are at least a dozen theories as to how it all worked. So far none of them handles every detail.

As for eternal subdivision, as far as I can tell you've contradicted yourself. First you say it is possible to subdivide the Planck distance, then you say it is not.

And we all understand what you just said.

And here I thought I was keeping it simple.

"time only exists collectively but things can only exist collectively if there are singular units together"

You haven't been introduced to orders of infinity, have you?

"As for where it came from, when the Big Bang occurred certain physical constants were 'frozen' into the spacetime continuum. The most famous is probably c = speed of light."

But the speed of light isn't constant.

Fine, if you want me to be more specific: The speed of light in a vacuum is constant.

I was going to try and explain further, but I found the info here: http://curious.astro.cornell.edu/question.php?number=630

According to my last roommate, it's not necessarily constant in a vacuum.

*does some web searching*

It looks like some physicists think it might change over time, but if it does, then Planck's constant changes with it, so that the speed of light times Planck's constant is always the same.

Hmmm... That's new. Looks like the change is pretty gradual, so far as they can tell. Interesting. *decides maybe it's time to start paying more attention to these things again*

actually I just read a article in new science about something similar and from what I got out of it that due to negative refaction the stars and galaxies may not even be in the postions that we see them thru telescopes. IF that is true then all of our measurements of the universe including light speed would be way off unless someone manages to come up with a mathamatical formula that takes the amount of neg refraction caused by black holes into effect.
