Gravity is the force that holds two objects with mass together. In terms of the planet Earth, we tend to refer to the gravitational force as the pull that keeps us all rooted to the planet. The theory of gravity was initially proposed by Sir Issac Newton, after an apple famously fell on his head while he was napping under it.

Later on Albert Einstein’s theory of general relativity was able to explain why things fall. And then proposed modifications to the theory made scientists suggest that the force of gravity may vary with time. This scientific theory was proposed by British physicist Paul Dirac.

Does that mean that gravity is reducing over time? What would that imply for us, the denizens of Earth? Will the gravitational pull become so weak that we would float about like cartoons float on the moon?

What about the moon? Would it eventually not be influenced by the gravity of the earth and move away from the planet for good? Thankfully, no. That is not going to happen. The gravity of the earth is more of less a constant force that will remain in effect as long as the mass of the earth does not change.
