Under current assumptions of the universe,
__..
q=RR/.R2=(4*pi*kappa*d)/3H2
where H is Hubble's constant, d is the density of the universe, and W is the amount of energy in the universe, we have 3 possible outcomes:
k, W = 0, q=1/2... rate of expansion -> 0 | t->:inf:
k=-1, W<0, q<1/2... rate > 0 forever.
k=1, W>0, q>1/2... big crunch
What I wish to discuss is possible ways to measure H, either through observation or equating terms with other equations. Also, I'm not sure why we can get the possible value somewhere within 25 of 75 but not closer, anyone care to enlighten me?
