Wobbles in time could solve gravity’s greatest mystery The question of how gravity interacts with the quantum world has long perplexed physicists, but wobbles in time could help us find an answer, finds Leah Crane THE most vexing problem in physics right now is how general relativity – the laws that govern gravity and space-time on large scales – meshes with quantum mechanics, the laws that govern very small scales. There are many potential solutions, none proven, and so far very few of them have been conclusively ruled out either – or even rigorously investigated. Now, though, the day is approaching when one of those ideas could be put to the test. …
