What would happen if only gravitons existed?

[QUOTE="ohwilleke, post: 5466293, member: 19562"] Gravitons couple to every other kind of particle and to each other, if they exist. (In contrast, photons don't couple to each other dramatically reducing the possibility of clumping and essentially ruling out collisions). So there is no fundamental reason that a graviton only universe couldn't produce ordinary fermions and bosons. On the other hand, this may be a fundamentally counterfactual scenario because in a graviton based quantum gravity theory gravitons come into being in the first instance because they are emitted by other fermions and bosons and there is no scenario in which you can generate of huge number of gravitons in a universe with no other form of matter or energy in it.
