It’s possible that the Big Bang produced a “mirror universe” where time moves backwards
In November 2018, three physicists from the prestigious Perimeter Institute for Theoretical Physics, in Waterloo, Canada, proposed an extraordinary idea: from the Big Bang not only the Universe we know but also another one that is ‘its image in the mirror’ arose. A Universe in which everything happens backward and expands backward in time. From our point of view, in effect, that Universe ‘on the other side of the Big Bang’ advances… into the past. In an article then published in ‘ Physical Review Letters ‘, the physicists Latham Boyle, Keran Finn, and Neil Turok thus argued that the Universe we live in is only a part of the real Universe and that if so two of the largest problems facing physicists (namely, dark matter and inflation) would cease to make sense. In fact, dark matter, the mysterious substance that accounts for almost a third of the mass of the Universe and that scientists are unable to observe, would be nothing more than ...
