Martin Rees: "This elasticity in the rate of passage of time may seem counter to our intuition. But such intuition is acquired from our everyday environment (and perhaps, even more, that of our remote ancestors), which has offered us no experience of such effects. Few of us have travelled faster than a millionth of the speed of light (the speed of a jet airliner); we live on a planet where the pull of gravity is 1000 billion times weaker than on a neutron star. But time dilation entails no inconsistency or paradox." Bravo Rees bravo Martin! The twin paradox should become "the twin consistency". Yet from time to time (not very often) the selfsame Martin Rees has doubts and organises a private conference: http://www.freerepublic.com/focus/f-news/519406/posts September 9 2001 "A GROUP of astronomers and cosmologists has warned that the laws thought to govern the universe, including Albert Einsteins theory of relativity, must be rewritten. The group, which includes Professor Stephen Hawking and Sir Martin Rees, the astronomer royal, say such laws may only work for our universe but not in others that are now also thought to exist.....AMONG THE IDEAS FACING REVISION IS EINSTEINS BELIEF THAT THE SPEED OF LIGHT MUST ALWAYS BE THE SAME - 186,000 miles a second in a vacuum.....Rees, Hawking and others are so concerned at the impact of such ideas that they recently organised a private conference in Cambridge for more than 30 leading cosmologists."
