Question 2

Suppose that the Hubble constant had the value 35.0 km/s per million light-years.
 
  (1 y = 3.156  107 s, mH  mproton = 1.67  10-27 kg, c = 3.00  108 m/s, 1 light-year = 9.461  1015 m, G = 6.67  10-11 N  m2/kg2)
  (a) What would be the maximum density the universe could have that would still allow it to expand forever?
  (b) Under the conditions of part (a), how many hydrogen atoms would we expect to find, on the average, in a volume of space measuring 3.00 m by 8.00 m by 8.00 m?
