I disagree that no one here is smart enough!
I happen to agree with G Alexanders first post that Einsteins special theory of relativity is wrong, and his explanation is refreshingly simple and original - tho not quite as well detailed as my own.
It surprises me that unfortunately the OP (original poster G Alexander) didn't participate in this later thread.
Entitled - what exactly is TIME - wherein I disprove Einsteins special theory of relativity and give a lot more details about the inadequacies of the Mitchellson Morely experiment and later the Sagnac Morley attempts with rotational analogue experiment.
Its a shame no one had the physics ability to continue the OPs post discussions with himself and they he didn't participate in the above thread.
Again I say it - essentially he is 100% correct n that Einstein was wrong with e=mc^2.
There is ONLY one value, for speed of light (universal constant C) that makes e=mc^2 correct - and that is infinity!
The speed of light is infinite
Infinity squared is infinity - no messy negative root solutions (i.e length contraction, time dilation etc etc required).
Simply, Einstein got it wrong.
The OPs first post was most excellently done & I concur with his findings.
