Einsteins theory of relativity...

I made some effort recently to try to solve Einsteins theory of relativity. I watched quite a lot of the television program Big Bang Theory. It is about a group of engineering students that major in physics. One of them says that string theory is what everyone cares about in scientific circles. When I was sick with Mast Cell Activation disorder, I used to watch this television program almost daily or at least once a week. Supposedly the main character called Sheldon isnt able to pass his PHD exam because he concludes that the only thing he can do about string theory is to conclude that they got it wrong. His friend suggest he might consider it important to make a statement that defines the theory, and which can be used to proceed. It is sometimes necesarry in physics to assume something is correct and go on from there. Sheldon fails at doing this, and string theory is no closer to ebing solved. Instead I decided as a former physics student and economics major to look at Einsteins theor...
