Gravitational Force is the force of attraction between all matter.
It is everywhere in our universe and affects everything in it. However, it is orders of magnitude weaker than the other forces. All of the other fundamental forces – Electromagnetism, the Strong Force, and the Weak Force, have strengths roughly within a similar range to each other. Gravity is on the order of 1040 times weaker than other fundamental forces in the universe. That means that gravity is 1/10,000,000,000,000,000,000,000,000,000,000,000,000,000 – or, a one hundred quintillionth the strength of the other forces.
General Relativity says that although gravity is not in reality a force, the geometry of space time creates the appearance of a force.
