At dinner party tonight.
We where debating the Big Bang theory of the universe and what was before the big bang.
Was the Big Bang a singularity?Infinite density and temperature.Followed by inflation of mostly dark matter. Causing the Big Bang.
Contraction of universe gravity energy stored higs particle and released?
Was it closer to cylic model of 11 dimensions. Collision with our 4 dimension concept with other dimensions?
Other point hard to grasp with universe is where does it start and end.The concept of time is ours.Time is non existent; it is all at once.Time is tenseless; past , present , future are equally real.
As to begining and end of universe it is a moot point.
