Hi,
Why have the hypothetical gauge boson of gravitation, the so-called graviton, a spin of 2 ?
What about his chirality ? (projection of spin on his propagation direction)
I mean, does it mean that the graviton can have a polarisation like a photon, but that this polarisation is two times faster ? What is the difference and why a spin of 2 ? If it's a boson, a spin of 1 could be 'enough'
Thanks
