Yes, this is the fundamental idea. The rest just follows from the math and other, older laws of physics.

Most people think Einstein was a genius. Even though he did poorly in school, it is generally assumed that Einstein became a genius later on. It's also widely believed that he used superior intellect and complex mathematical reasoning to finally arrive at E=MC2.
The truth about Einstein is altogether different. Even though he was pretty smart, his accomp scientific reasoning, how did he get there? The answer is very simple...
HE MADE IT UP!!

Given this fact, and given the fact that ordinary people like you or I wouldn’t have deduced E=MC^2 nor made any of his prediction then he must not only have been a lot cleverer than us but, virtually by the definition of the word ‘genius’ he had to have been a ‘genius’ for only a ‘genius’ can deduce things (whether through mathematical reasoning or ...[text shortened]... ry people cannot -that’s what distinguishes a true ‘genius’ from somebody who is merely ‘smart’.

Ok -first he didn’t “make it up” as proven by the fact that E=MC^2 has been proven to be correct along with many of his other predictions. If E=MC^2 was wrong then nuclear reactors wouldn’t work etc so it wouldn’t be credible that he just made up the equation randomly but rather he must have REASONED it out.
Originally posted by FabianFnasHe was the first to relate it to the idea of malleable space/time and he did in fact reason out the gravitational lens formula, Bending angle =4GM/C^2*r (4* gravitation constant * mass of an object in Kg/C^2 in meters/second * r radius of object in meters. For the sun, it comes out to about 8.4 microradians, or the famous 1.75 arc seconds of bending for a light traveling tangentially to the surface of the sun just skimming the surface. That is pure Einstein. He also reasoned out the mass of atoms by their brownian motion, so how many people did all that in 1905? Lets see, I think it was oh, maybe, JUST ONE. So that makes him a genius in my book. He also invented the magnetic refrigerator, being developed now, very efficient.

I see your crystal ball is still in working order. Rewriting history is pointless and an exercise in faith.
