Now, a new theoretical study presents a unique and surprising scenario that may provide some of the missing pieces of the puzzle. Some of the dark matter … Read more
One of the biggest unsolved problems in physics has to do with combining quantum mechanics and general relativity – two theories that are equally successful. And the latest attempt to close the bridge brings into the equation the explosion that started everything: the Big Bang. In a recent paper in Physical Review Letters, physicists at … Read more
A Theory of Gravity That Could Rewrite the Universe’s First Minutes The first fraction of a second after the Big Bang has always posed a problem. Physics can explain a lot about the universe once it’s stable and expanding, but in the beginning, when heat and energy were extremes, it was still hard to pin … Read more
