I think this has been asked before, but...

The metric of space-time is expanding, right? So, shouldn't time be expanding along with space? If time were to expand, would we notice at all, or would it take us longer think thoughts and to perceive everything, perfectly balancing out the effect from our perspective so that we didn't notice?

Prove/extend or disprove/salvage

(x) denotes subscript
Statement:
F(0)= 1 F(1)= 1 F(2) = 2 F(3) =3 .... denotes the fibonaccia numbers. Then for n > 1, (F(n)F(n+2))^1/2 is irrational.

And does a similar result hold for the number (F(n))^1/2
