General relativity and quantum dynamics don’t get along too well.
If you had to compare the two it would be like evaluating the differences between a Mac and a PC; both are well-honed examples of modern computing, but both are hopelessly incompatible. In computing, this isn’t too much of a problem, you either use a PC or a Mac, or you buy both for their individual strengths. But in physics, when you’re trying to find a unified theory, the fact that gravity has been outcast from the Standard Model club, tough questions need to be asked. Although there is some hope being generated by superstring theory, quantum gravity has a long way to go before it can be proven (although high energy particle accelerators such as the LHC might be able to help out in that department).
As pointed out by KFC at the Physics ArXiv Blog, “physicists have spent little time bothering to find out” how quantum mechanics operates in a curved space-time as predicted by Einstein’s general relativity. But now, a physicist has done the legwork and imagined what a quantum particle would do when faced with one of the most famous loopholes in space-time; the mouth ...
