That’s the entire reason quantum physics and general relativity don’t get along.

If quantum physics is right, gravity is a force that must be mediated by a particle…we call that particle a graviton. We’ve never been able to isolate one but the Standard Model has a very good track record of predicting particles that we later find, so this isn’t necessarily an issue.

If general relativity is right, it’s not a force but warped spacetime.

One (or both) is wrong. They can’t both be right in their current formulation.

A graviton makes no sense under general relativity, but we don’t have a theory of quantum gravity that “looks like” general relativity at large scales (where we can do very successful experiments) but still plays nice with quantum physics.

Gravitons are hypothetical bosons that would connect fundamentally matter with space-time. So you got the electromagnetic field, how do charged particles like protons and electrons know about each other? There is a concept called locality, it means that the universe has no magic, if you want to influence something you have to go there or send something there. But electrons and protons magically interact with each other from a distance. Well you got the EM field that connects them but they dont interact with the field directly either. The field interacts with them through its boson particle the photon. The strong force does the same with the gluons. So these bosons are transmitting information between fields and particles because locality. But gravity is still magic so we have predicted the graviton. The thing is we haven’t found gravitons but they are said to be even less observable than neutrinos. The predicted garviton is out of our measuring range so they can exist.
