 P: 45 According to Hubble's law, Velocity of recession of galaxies is directily proportinal to distance between them ie v=H0.r But, according to theory of relativity Time diliation t=t0.(underoot 1-v^2/c^2) as v->c t=0 That means the universe will expand upto a certain distance ( if the law hold correct) i.e 2.10^10 l.y After that the galaxies will slow down to the observer as
P: 372

Here i dont think its possible that $$v>c$$.Also if it were to be so you would get $$\gamma$$ as a complex number!
 P: 45 I meant as v is almost equal to speed of light, will the recession of galaxies slow down? because t~0
