Dale, I did not intend at all to insult you.

But what I feel strange is your few line answers to problems that have baffled theoretical physicists for long. Photon mass has been a big issue in Theoretical physics in the wake of Einstein's Special Theory of Relativity, and if in recent years it has been explained on the basis of photons having rest mass of zero and only having relativistic mass, it has been to make it compatible with Einstein’s theory rather than the other way round. Because with the mathematics involved with the Einstein’s Gamma factor, there cannot be any other explanation. Anything howsoever small its mass will have an infinite mass at the light speed. But this again is a philosophically questionable explanation. If there is matter, it must have mass, howsoever small it is. This goes to the credit of Einstein that his theory leads to singularities that have zero size with infinite mass and matter having some size but no mass. And lease first go in the history of this debate on Photon massbefore making your comments. Today you may challenge me; but time will come when Einstein’s light speed barrier will have to be given away; for it creates more problems than it solves. And of course the question remains (This question has been raised by Hawking also); how the natural laws all over the universe are same when there is not enough time since Big Bang to have been any communication between them. These are questions that will continue to be debated for long and your few-line dismissals will not bury them. Hawking has even given an example. He says that suppose a question is put to multiple students, and if they all give exactly the same answers, there must have been some form of communication between them.

What explains the harmonious system despite no way of effective communication is a question that has to be answered by current theoretical physicists if the current understanding has to survive. And it will not be late to say that the current sciences especially questions related to theoretical physics and evolution is in a very early stage of development.
