Is there any further explanation with arguments or experiments that you can give to back up that proposal? Well, also it depends with what you are talking about. If you mean the universe just after the Big Bang, then I think that the entropy was lower than it is now, and in fact the universe is still accelerating in it's growth, therefore the disorder must be growing now and thus be lower at the universe just after the Big Bang. But if we are talking about the universe before the Big Bang, that is a very different thing. We cannot really now yet if the entropy was big or small. Maybe it seems that it had to be small for it was all so concentrated, but think that all the mass was concentrated and thus all gravity, and all forces were mixed in their origin, so it might have been really the higher level for entropy than any other time.
