How does gravity work?
Question asked by: knowitall
Gravity is the force of attraction between objects. Every object with mass has a gravitational pull, it is just normally too small to be noticed - but even you have a pull on the objects around you. As it is a very weak force, it needs a massive body such as the earth to have a substantial pull, though you overcome this easily when you jump, before being pulled back to the Earth again.
It is not known how gravity is carried, over a graviton has been postulated as carrying gravity. Interestingly, if the sun were to disappear it would take us 8 minutes to feel the gravitational difference just like it would take us 8 minutes to see the light disappear.
