As the Big Bang started, all the mass of the universe was concentrated into one infinitely small point. This means that the mass density was infinitely large. Which has the same effect on the stuff there as travelling at light speed: no time passes for the traveller/amassed one. Therefore, at least for whatever was at the place where the Big Bang happened, no time passed and the question of what was before lacks a reference. Before and after are a matter of time, and where no time passes, before has no meaning
Einstein realized that same fact and had a very hard time agreeing with it...I read somewhere that the mass density was as big as several hundreds of thousands of tons per cubic inch :eek: amazing
