In response to Con McGillicuddy's argument (if one could even call it that) for the existence of God (Letters, 5 September), it is quite rare to come across such a grossly misguided and erroneous 'proof' of a deity.


I would suggest that if Con is going to start making statements on 'time' he looks at the science rather than blundering about and making childish remarks about the human calendar. What he has quoted is what one teaches a junior infant in school. What an astounding observation: "This journey brings about the four seasons of the year." Well, I think science can just shut up shop and go home. Obviously, Einstein's theory of relativity is wrong when compared to Con's neat approach to time.


Is there a constant universal time? The answer is clearly no. We all experience time as passing at different speeds, relative to our speed in relation to one another and the strength of any gravitational field that we happen to be in. This is the theory of relativity. I don't think it was in the Book of Revelations, but it should have been. Einstein's theory of relativity tells us that the faster an object moves the slower time runs, until at the speed of light time comes to a complete stop. This effect is known as 'time dilation'. For an example of time dilation at speeds that we are familiar with, an astronaut having spent a year aboard a space station will have aged 0.0085 seconds less than the rest of us that stayed on earth – hardly constant is it?


I believe Einstein wrote his paper in the years 1907 to 1915. Welcome to the future, Con, where ignorance is not a virtue.
