Roger Penrose really is the most advanced thinker in all of this and addresses OPs points.
Universes, born from a lack of mass/time, repeated forever. The big bang wasn't a single event, just a single event for 'us':

Why can't it be there ?
To counter your argument though, the 1st law applies to this universe, if the universe didn't exist until the expansion began, then technically there was no 1st law prior to expansion
The First Law of Thermodynamics states that it can’t just be there. It literally says it?
Sure it can be, but then you have to ignore the law of thermodynamics?
which was my point in the OP.

There is a theory which states that if ever anyone discovers exactly what the Universe is for and why it is here, it will instantly disappear and be replaced by something even more bizarre and inexplicable.
There is another theory which states that this has already happened.

they're also freaking scary.
remember the brian cox explanation of the term "event horizon" being the point where without breaking the speed of light all of your possible future scenarios are "be sucked into a black hole"
even worse is the assurance that spaghettification would likely see you dead long before this point.
but yeah, terrifying to think of an entity of such power that getting too close has literally no possible outcome other than oblivion.
the laws of thermodynamics (along with all the other universal laws) are only valid within the confines of our universe as we understand it, the events preceding the big bang are not within our universe so we can't be certain the same laws apply.

The laws of thermodynamics didn't apply at the Big Bang, it was all a bit weird back then.
Asking Stephen Hawking today would be even harder then proving the Big Bang and what there was before the Big Bang.

Don't even try and grasp it. It's an absolute mindblower and will only lead to true insanity or actual terror if you do.
I've had many a sleepless night when I've had breakthroughs in my understanding of it.

She was shacking up with Leonard in real life, big bang right there.

I thought the latest theory was that there was energy before the big bang. Can't remember the name of it now......
If only you'd managed to make that post 42 instead of 66.
The Laws of thermodynamics only work when you have a fourth dimension. If there was no fourth dimension before the Big band there is no law of thermodynamics until the fourth dimension is created at the point of the big bang. If it is correct that there was no 1st, 2nd, 3rd or 4th dimension before the big bang you don't have to worry about the law of thermodynamics until the point each dimension is created.
Ha yes. Good documentaries seem to be lacking these days, its a truly fascinating subject. I got my first telescope young and have been hooked ever since.

I can't stand the show

You know the bit where Lister jump starts the second big bang, with jump leads from Starbug?

There's only one way energy could be delivered to a singularity in such a manner as to cause the largest explosion ever known......yodel
It depends whether time is the consequence of causality or the cause of it. We know that the speed of time can speed up or slow down. Assuming that time is just causality (with a cause having an effect) then the speed of time is really just cause and effect occurring at a different pace. If time can slow down then it could stop. No cause and effect is taking place. This may be what the universe was like before the big bang; there was no cause and effect taking place. If everything was in stasis with nothing moving, nothing changing, nothing happening, then there is no energy.If there was no time then nothing would have happened at all right?
But that doesn't answer the question about why we went from no energy and no causality to enormous amounts of energy and causality (time).
