I’m no scientist, but there is some debate about whether it’s a fundamental force. Some think it might be like centrifugal force which isn’t “real” but shows up in a certain reference frame. Gravity might actually be a result of thermodynamics and entropy.
Comment on we are but a gravy train in outer space
quicksand@lemm.ee 7 months agoYes it is. We just don’t know what makes it work

There are many things than we experience as forces but may not be actually if you change the reference (ex: centrifugal force is inertia) or if you go deeper into unification (ex: electrostatic force and magnetic force can be unified into electromagnetic force). But physics is about modeling reality in a convenient way for you current reference, we will never be certain to have the “real” final force model.

In our current understanding of physics, it’s an effect from the curvature of space and not a force. Quantizing gravity results in unphysical divergences. Whether there will be a way to model gravity as an exchange of particles, we can’t know for sure. So according to our current knowledge, it’s not a force.
