Does Loop Quantum Gravity support the existence of graviton?
I can't imagine how is it possible that graviton can exist if it is to agree with GR, since GR says that gravity is merely a curvature of spacetime and is isn't a force.

GR => SR => time dilation & length contraction =>> how does graviton be able to explain time dilation and stuff like that? Am I missing something here?

Do you understand how you can have time dilation and length contraction in classical linearized gravity?

No, I don't. Can you explain?

Thread 'Quantum behaviour of an electron around a positively charged sphere'

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
