Paul Dirac proposed that gravity was stronger in the past because G, the gravitational constant, is getting smaller as time passes.People who object to this idea say that the Sun would have burned up far more fuel by now if gravity had been a lot stronger millions of years ago.But what if the coulomb constant,k,was also stronger in the past - would Dirac be right then? Why would these constants be larger a long time ago?
