In fifty years we might discover smaller particles than quarks
Ok, but the corollary to my previous question is, is there a limit to to how much smaller particles "might be"? And if so, that would place a limit on how short a time interval there could be. I suspect it's longer than 1/googolplex of a second.
This has been theorized as 10-43 (that's 10 to the neg 43) sec,
That doesn't even come close to a "googolth" of a second, much less a "googolplexth" of a second! A googolth of a second is 10^-100, and a googolplexth is 10^-(10^100).
I bet there isn't even a googol number of anything in the universe (isn't there only about 10^50 subatomic particles in the entire universe?). In order for there to be a googol number of as yet undiscovered sub-sub-...-atomic particles, you would need an average of 10^50 of them in every subatomic particle in order to wind up with a googol number of them in the universe. It's not likely.
A googol written out is 10,000,000,000,000,000,000,000,000,000,000,000,000 ,000,000,000,000,000,000,000,000,000,000,000,000,0 00,000,000,000,000,000,000,000,000. The number of particles in the entire universe is about half as many digits (if my 10^50 figure is anywhere near close!)
It's impossible to write out a googolplex, it would be 1 followed by a googol zeros.

If any distance is divisible, then we should never get where we are going. If you are going to walk a mile, first you have to walk 1/2 mile. Then you would need to walk 1/2 of the next 1/2 mile, or 1/4 mile. Then, 1/2 of that 1/4 mile, or 1/8 mile, etc. etc. etc.
But it also takes only half the time to traverse each succeeding fraction. And we know that the infinite series 1/2 + 1/4 + 1/8....converges to 1.
So you do reach your destination after all.
If it's infinite, how can you ever reach the end.
For the same reason that an infinite number of rectangles fitted to a curve (as in calculus) adds up to a finite area.
An infinite number of things can add up to a finite quantity.
Kevin: Nice post. I've met way too many people who think that since we have 10^50 particles in the universe, then we're half way to reaching a googol.
Half a googol is 5 * 10^99, or 5 followed by 99 zeros. Quite a bit more than 10^50 (1 followed by 50 zeros). Those zeros count for a lot!
Dang, I sound like a geek! Must be because I are one!
