Ah but where Einstein and String theory fail I didn't. Now we have a measurement of everything known to us from speed to light. If we put them together Physical Relativity (PR) that we can can touch, smell, taste, see, and hear in this dimension is PR. Now Time and Space (TS) come into play because without either of them the universe wouldn't have started in the first place. Einstein no matter how brilliant the man is he didn't have the resources nor he didn't have our evolutionary 100 IQ point increase. String Theory they could have done it but there entire theory was everything was connected by strings.
