Why does the force of gravity exist?
Why can’t physics prove that gravity is an electromagnetic force? What is the opposite and equal force of gravity? What is the difference between force of gravity and gravitational force? Why is gravitational force weakest, among the 4 fundamental forces? Difference between gravity and gravitational force? What is opposite force of gravitational force? Why do the equations for the force of gravity and electrostatic attraction look so similar? Is the same true for the other fundamental forces? Is there any connection between gravity and magnetic fields of force? Are gravity and forces energy? Is the force of gravity a scalar or a vector? Is there is any relation between magnetic field and gravitational force? 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? Why is gravity not as strong as electromagnetism? What is the nature of mass, gravity and space? Why do fundamental forces like gravity and electromagnetism follow inverse square dependence only? What is the meaning of 50 times force of gravity? What is gravity? What is gravity? Why in the whole universe gravity causes centripetal force? What is the force that opposes gravity and prevents objects from collapsing on themselves? Does every object have gravity? Physics: What is force? What is a gravity well? How strong is gravity on earth? What is the concept of force? What is the definition of gravitational field strength? What is specific gravity? Does imaginary gravity exist? Is there gravity without mass? Does gravity have a particle?
