no sir. well. they found it.. but its not what provides mass. 
Look, you're being lied to at such an astounding level it's insane. Most of what you know is bullshit, based on a lie.  

You need to start from zero, pretend you know NOTHING and do base research yourself. There is no other way to do this.  So much is a lie, starting with Gravity.

So much is based on gravity being what They say.. and sure the force downward is 9.8m/s^2 but that does not mean their theory of why is correct, and I would assume incorrect if it's still not proven. Same with evolution. Until this theory is proof, I'd question everything you are told.

It's very easy to fool people, it's very hard to tell people they are being fooled.
