If a particle and an antiparticle "pop" into existence, and immediately annihilate each other, doesn't that still violate conservation of energy? Shouldn't they release a burst of pure energy? That's how regular particles work, right?

What is the definition of a graviton? Why do we not see any signs of gravitons yet, if they are supposed to be the force carriers for gravity? Shouldn't they exist in huge amounts everywhere and all the time?

In the Stern-Gerlach experiment, the ion beam was split in two. How come we can't just explain that through the action of charges? Why do we need to invoke spin?

Could the graviton field not work by exchanging gravitons between particles like the fields of bosons Y, Z and W, but with it forming a "web" that is deformed by objects and that affects spacetime directly?
