UNIVERSE BEFORE TIME.

Canadian physicists have put forward a new theory suggesting that our universe may be part of a larger universe that existed before the Big Bang. This theory offers potential explanations for mysteries such as dark matter and the dominance of matter over antimatter. The researchers propose that in the mirror-image universe on the other side of the Big Bang, directions are flipped, time runs backwards, and antimatter particles are dominant. The theory also suggests the existence of right-handed neutrinos, which could provide a simpler explanation for dark matter. While still in its early stages, this theory offers a simple explanation for certain aspects of the universe without requiring additional dimensions or particles. [Extracted from the article]
