well, lets put it this way....either the universe is finite or it isn't.....in the post I replied to you proposed a universe that always was and needed no creator......
however, science tells us the physical universe we live in did in fact have a beginning....so, whether you fall on string theory or some other method of traversing from some other universe to ours, it will in fact be a metaphysical explanation......
now if you argue instead that the universe is finite it needs to have a beginning and a cause.....can you postulate a beginning or a transition that resulted in our current universe that does NOT require a metaphysical explanation?......
Sure. That is an easy request.
First let me say that there was no "first". What you insist is the beginning I insist is just a point in time along the way for the stuff which after the big bang expanded into what we call our universe.
As far as I can tell the "big bang" scientists believe that in what YOU call the beginning all of the material needed was in the space of roughly a basketball. Some condition had arrived that the supercondensed material release it's hold on itself and voila a huge explosion that as far as science can tell is still expanding outwardly.
But let's go back before the bang. There WAS this basketball sized stuff. Who knows how long this form had been in existance?
I have a very difficult time postulating a metaphysical force or being standing apart or infused within this supercondensed universe.
"science tells us the physical universe we live in did in fact have a beginning"
I do not believe that statement is true in the sense that there was NOTHING that became SOMETHING at the moment of the big bang and I don't believe science says that at all.
Religion/s say there is a beginning in the sense you seem to imply. I don't think there was anyone around near the time of Jesus qualified to explain the earliest form of the universe.
The invention of the first telescope, an extremely crude device, wasn't thought up for approximately 1500 years from the time of Jesus.
The printing press was invented in 1439. Knowledge of ANYTHING was extremely rare and difficult to obtain before that. Almost EVERYTHING in existance was explained by various metaphysical forces before that.
"now if you argue instead that the universe is finite it needs to have a beginning and a cause"
But I do not argue any such thing. I ONLY argue that the universe has existed in this expanding form for a very long time, possibly much longer than is accepted by science. How long it existed in the condensed form?? I have no idea.. Before that? a huge black hole that had swallowed up a previous universe?? and so on and so forth back into time infinitely.
The possibility that the universe needs to represent "a cause" is laughable.
Have YOU ever contemplated just how small we are? Pardon me assuming that this "cause" is in relation to "us" and provided by "god" on our behalf.
THAT is a silly concept. I will leave it to others of a much higher degree of hubris and humor than I to expound on this "cause"...
