Hi all,
I am not very good in quantum mechanics but i suppose everything is quantized in QM. Then does gravity have some basic quantum (like photons for light)?
 
Physics news on Phys.org
At the present time, there is no generally-accepted quantum theory of gravity, so it is not possible to answer this question for sure. It is an active field of theoretical research, but so far there is no definitive conclusion.
 
However, you might want to try looking up the word "graviton".
 
My understanding is that the graviton is a rather speculative object.. if there were a quantum theory of gravity, it would probably have an object that people call (in advance) a graviton.

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!
