Just a thought. There is no easy way to learn. May I suggest that you buy a book. It can be fascinating.
If you want a very basic book that cover a number of interesting fields I'd suggest
A Short History of Nearly Everything by Bill bryson
If you want something a little more in depth but still very basic I'd suggest
The Fabric of the Cosmos by Brian Greene
Both great reads. Have fun
Everybody is entitled to my opinion.
