Universe without He and with 100% of He

  1. May 17, 2010 #1
    What if during few few minutes the % of neutrons was different and there is absolutely no neutrons (and He) or the number of n = number of p (so all gas is He4)?

    My guess:

    1. Universe without He would be no very different from what we have now, stars will be able to form, even there characteristics will be slightly different. After 1-2 star generations there would be almost no difference with what we have now,

    2. Universe with 100% He would be very different, but there will be massive stars. These stars would use triple-aplha reaction from the very beginning.
