Matter curves space-time. Universe is expanding with anti-particles bringing a rebound. The universe does not withdraw into itself or escape too quickly.

In 1998, the BOOMERANG program was rolled out. Then came MAXIMA and DASI. We are in a flat universe.

If the universe is flat, the big bang’s outbreak was precise at one on 1050. This is a prodigious accuracy. The slightest distinction should have made the universe fold or expand indefinitely. So with that, there should have got no chance creating our universe.
