A new recipe for gravity could help solve some of the universe's greatest mysteries. It suggests that the concept of "quantum gravity" could arise from entropy, possibly solving puzzles put forth by the elusive dark universe — and, if true, this novel theory could also finally unite Albert Einstein's general relativity with the quantum realm.
Since the beginning of the 20th century, Einstein's theory of general relativity has been the best description we have of how gravity works. However, right around when Einstein came up with general relativity, scientists also developed the foundations of quantum mechanics.
Since then, both theories have been tested, revised and improved, standing the test of time and winning over skeptics in the scientific community. There's a problem, though — a big one. They can't work together.
