If gravity is not as a force, but a consequence of masses moving along geodesic lines in a curved spacetime then what is a Graviton?
In: 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.
