qqp question1: Is quantized gravity 'empty' space being a sea of massive particles which are displaced by matter and push back and exert pressure toward the matter? question2: If Einstein's theory of general relativity says that gravity is the result of curved spacetime and that matter, such as a planet, has no force whatsoever that pulls other matter towards it, how are we able to walk on the Earth without falling off? Is there a force pushing on us?
