My question is the title itself. ..... Why does a spin O graviton predict that a gas will be less gravitational when it is hot than when it is cold?

I know this contradicts observation, and that a quantum theory of gravity based on General Relativity will have a spin 2 graviton.

My question is about a spin O graviton that you would get by quantizing a scalar theory of gravity, such as Newton's or Nordstrom's.

  • $\begingroup$ @Qmechanic I googled for this 0 spin graviton, there is a Horava-Lifshitz qft and it is not simple. to come to find predictions needs a specific link ( let alone to answer why, which will have to do with the mathematical formulae) see this arxiv.org/abs/1408.0268 $\endgroup$

  • $\begingroup$ My reference for this question is: I read it in the introduction to " The Feynman Lectures On Gravitation" book, but it didn't explain it in a non-mathematical way. $\endgroup$
