This probably sounds frivolous, but I think the question of infinity is a difficult one and needs to be considered.

In my model, there is an infinite number of pulsations before 'the present one' and an infinite number of pulsations after this.


Cantor would be proud of you; you have two infinities. The trouble is, one has an end, and the other has a beginning. Possibly that is acceptable in maths, but as a real thing it has flaws.

There never was nothing.
