Out on the cusp of human knowledge, particle physics can seem very esoteric indeed.
Some theories in particle physics speculate that it might, although these dimensions would be curled up in loops so small, they could probably be probed only in high-energy particle collisions.
The theories of particle physics predict the strength of dark energy to be about 120 orders of magnitude larger than what is observed, and general relativity cannot explain this enormous discrepancy.
But they could cause a proton to decay — a very big deal, if it turns out to be correct, since proton decay isn't allowed under the current Standard Model of particle physics.
