## Main Question or Discussion Point

Is there a generally accepted Physics explanation of the apparent "small entropy" of the big bang vs the apparent "large entropy" of theoretical the big crunch?

I remember that it is linked to the theory as to why we have no observed white holes in the universe though (and why it's predicted that there will be none).

Then it seems logical that at the time of the big bang when the number of particle types and fundamental forces was at its lowest(or so they say) and energy was distributed most evenly in space entropy was also small. And take today(going towards the big crunch can only make it worse) - we probably have as many particles as there are physicists :P

Anyway, I have my own answer, and wouldn't mind feedback. It is clear that the order of a point in dimensionless space is infinite, so entropy = zero at the big bang. I have seen some describe the big bang as not only an expansion of mass and energy, but also of spacial dimensions themselves - this would make it meaningless to ask what was "there" before the big bang occurred. However, if these dimensions persisted during a big crunch then it seems to me that entropy would approach infinity because the backdrop is now continuous and possibly infinite (i.e. the point has many/infinite locales).

In other words, entropy of a point in dimensionless space = zero, while entropy of a point in dimensioned space = infinity (or approaches infinity as the dimension grows, if one wants to reject the continuous nature of space)...
