Einstein’s theory says gravity is not a force but the bending of space-time. However, in quantum mechanics, everything’s about particles and forces. Gravitons come in here, thought of as the ‘force carrier’ for gravity. The big problem? These two theories, Einstein’s relativity and quantum mechanics, don’t play nice. So, scientists are still figuring this stuff out. It’s like trying to merge chess and checkers into a single game. We ain’t there yet.
