Let’s take the argument you proposed a long time ago, Kamui.
I objected that that thing you defined as uncaused could be the initial singularity. You objected that that is “physical” and thus cannot be the uncaused thing.
My questions are, what does it mean to be physical, and why does the initial singularity necessarily satisfy this definition? And, why can that which is physical not be the uncaused conclusion of the argument?[/quote]
Forget about its physicality.The application of the notions of matter, space and time become a bit tricky at scale smaller than Planck length and “before” Planck time.
But there is no need to wander there :
we have determined that every contingent thing is caused by something else.
So we can affirm that the uncaused cause is non-contingent.
In other words, our uncaused cause necessarily exists, in the same way 2+2=4 is necessarily true.
The singularity doesn’t exist anymore, so it fails to satisfy this criterium.

If the initial singularity is “the gravitational singularity of infinite density thought to have contained all of the mass and spacetime of the Universe,” it doesn’t seem to me like it doesn’t exist anymore. It’s changed–into the horsehead, into the solar system, into you and me. But it isn’t gone.
Edit: In other words, if the singularity is just a state of the universe, then it cannot be said with certainty that the universe does not necessarily exist.[/quote]
This is what I was getting at earlier. Everything that makes up the universe was at some point caused, or itself was uncaused. Then it changed form until you see the end result today. This does not involve some infinite or really long causal chain in either direction.

Agreed, so what are you getting at?[/quote]
No infinite causal chain, that seemed to be a problem a few pages back…[/quote]
The question often comes up, but you are right causal chains cannot be infinite because regressions cannot be infinite.
