The Hypothesis is that the Graviton could be the force carrier for gravity. But with the knowledge of Einsteins theory of relativity which states that Gravity is NOT a Force, wouldn’t the Graviton disprove Relativity or at least some aspects of it?
In: 111
No one is pointing out that Einstein himself considered gravity a force. The geometric nature of the math does necessarily mean gravity is not a force.
This Quora answer conveys problem of this line of thinking must better than me.
Answer to Why do physicists consider gravity as one of the 4 fundamental forces, but according to the best theory of gravity (GR), it is not a force at all? Is that why unification is not possible with QM? by Viktor T. Toth

Gravity is not a force in general relativity.
It can be considered a force in quantum mechanics.
There is no particular reason that we should assume that it’s General Relativity that’s the more correct version.
Most likely, both are actually slightly wrong and we need a new theory that encompasses both of them. Something that looks like quantum mechanics on small scales and looks like general relativity on large scales, and then also works on a scale where both are relevant.
I don’t know why answers to this on reddit tend to assume that Quantum mechanics at fault at that the idea that gravity isn’t really a force must be the correct one.
The truth is, we can’t currently reconcile this apparent contradiction between QM and GR. Anyone telling you they perfectly understand gravity is either an idiot or a liar.
In string theory, for example, there is a graviton. But string theory would also reproduce the results of general relativity. If that were true, then both general relativity and quantum mechanics would turn out to be slightly inaccurate models for the real truth.
What does Einstein mean by gravity not being a force?
For over 100 years now there have been two fundamentally different theories of physics, quantum and GR. No one likes this, it would just be nicer if there was one. THERE CAN ONLY BE ONE!
The problem is not that they are different, but that they are *fundamentally* different. Like so utterly different that it’s hard to imagine how they could be put together.
Instead, people have been trying to use one model to build a theory that explains the other.
There have been any number of attempts to “dimensionize quantum”, that is, try to explain quantum like physics using a GR like theory. This generally failed to progress as QM got more complex with things like isospin and color charges and such. You ended up needing a whole lot of dimensions and the theories invariably collapse under the weight.
There have been even more attempts to quantize gravity. In QM force-like things happen when bosons are exchanged between particles. So gravity is force like, so we have to have some sort of boson, so let’s call it the graviton. No one has been able to make these theories work either. It’s not the only way to quantize gravity but it is one of the most direct and so it saw lots of attention.
There’s lots of others that aren’t one or the other or even a blend of them, but they tend to do even worse.
