Trying to wrap some sort of understanding around this.....
We have a bang, an explosion of some great magnitude of unimaginable power.
It is so humongous it disrupts whatever was there.
Does it blow outward, radiating from its original center?
What replaces it, and why?
Where did it come from?
Does the theory of every action has a reaction apply?
If yes, does that mean back to its original formation of what blew apart?

I believe,  (do not study, Just  Explosions)
so my explanation, is from what I have learned.

All things, are made of ‘atoms/quarks’.
Those  ultra little things, which can’t even be remotely seen  with the Human eye,
(Without  Great  Aid, of some device)
Are  Still Their. Just a different form.

I Take 100 pounds of wood, burn it, and have 2 pounds of ashes.
That, engery, is still their, it is just now, in many other forms.

Harder to see.  A  Firecracker.
It has, paper, and a compound.
It explodes, it, disappears.
(To our human eye)
But the  Energy, is just in many other forms.

Does the theory of every action has a reaction apply?

I would say yes.  Just that some, reactions, we cannot see.
Unlike, Newton’s cradle.

If the, ‘Big Bang’,  is  referencing, Trumps win.
Don’t think things will go, ‘back’.
What happens next, is the result of, what we do.
