What is cause of gravity?
What is the cause of earth's gravity?
Is gravity of the earth constant? Why does gravity act downwards? Why is everything attracted towards the center of the Earth? What does gravity do? Is gravity itself a form of energy, or does energy cause gravity? What prevents the Earth from collapsing under its own gravity? What is the value of acceleration due to gravity at the centre of earth? Why? And also what about gravity? Is the gravitational force of earth increasing? Why do we take gravity as a constant? Is there no gravity inside the Earth? Is there no gravity inside the earth? How is gravity produced? What are the application of specific gravity? Why is gravity zero at the center of the earth? How does gravity work, and is gravity a matter or something else? Is there any relationship between earth's natural magnetism and earth's gravity? What is centre of gravity does its changes? In what way mass affects gravity? Does mass have an affect on gravity? Does gravity affect energy? Why in the whole universe gravity causes centripetal force? How does gravity work? How is the gravity work? What would happen if Earth’s gravity were to double? What is a gravity well? What would happen if the gravitational force of earth increased suddenly? 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? Why is gravity constant? How can gravity affect energy? How is zero gravity created on earth? Is energy the source of gravity?
