@Sea Breeze: that is indeed the current understanding of physics. Time is a construct of the current laws of physics as a result of the interaction of gravity and space, it has not always existed.
Although a lot of these things don’t make intuitive sense (we didn’t evolve to live in a place without time so it can be hard to understand) but the math is rather simple and easy to understand.
Simple things can have complex results, for example the Mandelbrot set is easy to compute and define (z^2+c) but infinitely large, complex and “beautiful” to look at.
Basically you have two proponents: infinite regression of more complex creators or the regression to zero of less complex things that create more complex things through simple processes. We have evidence to the latter, from zero you get virtual particles that eventually interact and create a Big Bang (which wasn’t really a bang but more of an inflationary period). For the former there isn’t much evidence, if any, nobody even amongst its believers agrees on the evidence. Arguing for more complexity as the cause of less complexity (turtles all the way down) is possible, just less understandable and not mathematically sound.
