Special Relativity is easier to understand than General Relativity. On a systems-category/wicked-abstract level it's like "Macroevolution" and "Microevolution".
Special relativity is like how if a car going 50 mph east collides with a car going 50 mph west it's the same situation as a car going 100mph hitting a stationary wall. When a train is moving at 35 mph and you're driving 50 mph in the same direction and you're passing it at 15 mph, that's special relativity.
Everyone knew about 'special relativity' Galileo wrote about it, it was a label put on something really everyone always knew. This is similar to how everyone knows about "microevolution" farmers and herdsmen have been manipulating animal and plant DNA for centuries. "Macroevolution" like general relativity required a global perspective.
Einstein wrote about General Relativity for the first time ~ 1907, it is the idea that everything that moves moves at a rate that is relative to the speed of light.
General relativity has the implications for the clocks and the twins where one goes off in a rocket ship and comes back and the Earth twin is so old. Einstein's theory had it's basis in differential geometry and was verified by Arthur Eddington's snapshots of starlight that bent as it passed through the Sun's gravitational field in 1919. The comment you're replying to had the two topics switched around.
That's not special relativity, that's Newtonian dynamics. Special relativity does have the implications for the clocks and the twin paradox, and general relativity is roughly special relativity plus gravity.
Well, that's embarrassing, you're right. I confused the historical existence of the principle of relativity and how general relativity generalizes special relativity and took them further than they actually go.
