What is cause of gravity?
What exactly causes gravity?
How does gravity work, and is gravity a matter or something else? How is the gravity work? In what way mass affects gravity? What is a gravity well? Does gravity affect energy? Why is gravity constant? Does mass have an affect on gravity? Why does gravity exist? How does gravity attract materials? How can gravity affect energy? Why do we take gravity as a constant? How is gravity made? What are some of the applications of specific gravity? Is gravity and forces energy or caused/created by it? Is gravity constant? Why or why not? Is there gravity in space? Does gravity actually exert a force? What is centre of gravity does its changes? How does the gravitational force cause the bending of space? Is gravity a law or a theory? What is the acceleration due to gravity? Do we have 100% proof that gravity is caused by the bending of space by matter, or is this just a hypothesis which satisfies observations? Is there gravity in a vacuum? Does every object have gravity? Why does gravity act downwards? Why is everything attracted towards the center of the Earth? Is gravity a particle? Is gravity only a theory? Why in the whole universe gravity causes centripetal force? Does gravity have a particle? Is energy the source of gravity? What are the advantages and disadvantages of gravity?
