Earnest question.
Jan. 9th, 2004 09:01 pmColdplay - [Clocks]--- I'm asking, here, because i think a number of you could explain it better than i could read it. How do we know how many atoms, molecules, etc, there are in the universe? Are we approximating, and assuming, or what? How do we know any true rate of universal expansion, for that matter? Are we assuming it's still the speed of light? Could it Not be? Could it have slowed?

It may catch the particle and destroy everything in a grand cosmic "phoop!"
oooooooooo... scary!
