I don't think anyone truly understood what this person was saying.
He is asking several things.
Is the big bang done or is it still exploding; the universe is expanding after all?
How do we know the expanding universe isn't the effect of an on-going explosion?
Finally, for some reason, I suspect myself and many others have imagined something similar to the following mind-bender. For some reason, I seem to think that the matter within the billions of galaxies that exist today and that stretch through nearly the beginning of time that this represents a fraction of existing matter from the beginning of time or a fraction of the existing energy/particles convertible into matter from the beginning of time. Let try to refine that mind-bender.
I know the visible matter in the universe is 4.6%, is that percentage growing as time goes by?
In other words is the universe as a whole done converting non-visible matter into visible matter?
Or is the percentage of visible matter expected to grow not due to universe processes but due to ongoing big bang processes?
If you think I am confused, then please tell me everything I need to know so that this matter never confuses me again.
