Who is the top physicist skeptical of gravitons?

[Quantum Bum]

Who would you say is the leading physicist, if any, who does not believe in gravitons?

 

[Varon]

We don't have a real theory of quantum gravity yet, so people are not sure. But it's an interesting question. Share it with us if you found the answer.

I would say he/she is leading in something that has not much to do with gravitons.

Newton.

There are other physicists who don't believe in gravitons but he is probably the leading one.

I don't think any of the popular approaches to quantum gravity specifically say the energy of gravitational waves is not quantized (the basic definition of a "graviton", see the last section here), though some may not be developed to the point where they can model gravitational waves. Anyone know of any non-crankish approaches to quantum gravity which actually rule out gravitons?

I am certain that quantum mechanics appeared recently (compared to Newtons time) i.e wave /particle duality. So it's a little far fetched to mention Newton.Also I assume that by 'leading' OP means of the current ,modern age.I apologize if I am mistaken. Regards,

We do have a very good theory of quantum gravity, it's called effective field theory. And it has gravitons.

Whatever happens at high energy makes no difference to low energy physics. This is why can describe the world very well without knowing the real fundamental degrees of freedom.

Pion QCD for example is the same. It is not renormalizable, but we can use it as an effective field theory to make accurate predictions about QCD.
