You don't think space and time, or spacetime, don't exist?
What cave have you been holing up?
Are you saying that the physics and cosmology of the BB has changed and not space and time are thought to have existed always? What makes that more right than the previous ideas that space time started with the BB?
Is that like the idea that time had to have had a beginning or we could not be here yet is wrong because Mathematicians have theorised the B model of space time which I hear says that everything, including time has always existed? and we can go forwards or backwards in space time even if cause effect shows time as a one direction thing. I hear this model is accepted by most physicists these days.
It gets over the need for a beginning and a beginner(even though it seems that the B Model has a beginning point somewhere in it) but still it's even weirder than hypothesising a God, and when you think about it, it does not get over the idea that we could not be here yet if time was linear because it says that space time has always been,,,,,,,,,,,,,,,,,,,,, sort of like the linear model is still there except once removed,,,,,,,,,,,,,,,,,,,,, like saying that God must have had a cause, and so first cause has not been eliminated just moved back a bit,,,,,, once removed.
But really who am I to say anything about any of this, I'm not a scientist of mathematician.
