The Theory of everything? That's easy.

Everything = Is.

Even nothing "IS" something not being.

But in your haste to name "geniuses" you forgot the greatest and most excellent example of true genius, Nikola Tesla. For there has never been anyone to even compare to his level of genius.

And we do have the ability to be limitless.
To posses talents skills and abilities beyond that which we deem difficult or unattainable. We have only restricted ourselves to be limited to our own belief of limitations so we do not even attempt to expand ourselves.

Those who know of great secrets keep that knowledge for themselves and those who figure it out are called Conspiracy Theorist and Crazy, and are hunted down and marginalized by those in power who know how to use these same powers, but there is good news.
The tide is changing and soon we will all see a brighter future.

Hang in there.
