I see that you keep getting threads closed because you REFUSE to accept the answer you've been told several times. WE DON'T KNOW.

It's even worse. We cannot know. We cannot even pose the question! @curious222's "before" means $T<0$, but $T$ is only defined in the range $T>0$. There was no time prior to time!

Nobody knows, as we've said to you before.

Question is answered and this thread is closed.
