I'll tell you how I learned about gravity.... by choosing to study Physics as a GCSE, and later reading numerous books by learned and intelligent men who try to bring enlightenment to the ignorant....

As a starter for 10 I'll link some sites that explain gravity below, starting with the ever popular (but occasionally incorrect Wikipedia)....

There are many more sites online that can explain Gravity, but happy reading with the list above.
