Thanks for the responses . From your responses I think I am starting to understand that the issue might be more in the way I am thinking about the problem. I guess classical mechanics is not a good way to visualise any type of quantum theory. I need to expand my classical mind Although we have no full quantum theory of gravity we accept the experimental results of the attraction of particles that give us an insight to the different world on a quantum scale (Charges and spin causing attraction). Does this mean QM and GR or both are compatible theories in explaining forces including gravity? I was under the impression that they both are unable to be correct. GR breaks down at the big bang and QM violates some of the fundamental principles of GR such as quantum entanglement information transferring faster than the speed of light. Cheers, Mozilla

Hi, I have a question. Apologies as I have no background in science/physics and have just started so my language may be a bit elementary. I only know what i have read. Now to the question ... I understand general relativity specifies that gravity is the curvature of space which causes the earth to orbit the sun. That makes sense in explaining the attraction of the planets. However quantum mechanics specifies that gravity is due to the exchange of virtual particles known as gravitons. So how can two sub atomic particles exchange energy that causes them to be attracted to each other? One particle releases a graviton that another absorbs. How can that cause attraction? If anything would the second particle be disturbed from the energy absorption? I guess the same question applies to the attraction of the electromagnetic force . Thanks in advance!
