| Lord Martin Rees, President of the Royal Society: "Good science
| fiction should respect the fundamental constraints of physical law. In
| that sprit, it is worth mentioning that an observer could, in
| principle, observe the far future in what, subjectively, seemed quiet
| a short time. According to Einstein, the speed of a clock depends on
| where you are and how you're moving. If your subjective clock ran very
| slowly compared to the cosmic clock, you could travel "fast forward"
| into the future. This would happen if you were moving at a velocity
| close to the speed of light. Furthermore, strong gravity would distort
| time; clocks on a neutron star would run 20 or 30 percent slower. Near
| a black hole, the distortions would be even greater. If you were to
| fall into one, your future would be finite; you would be ripped apart
| - spaghettified - by ever more violent gravitational forces. However,
| a more prudent astronaut who managed to get into the closest possible
| orbit around a rapidly spinning hole without falling into it would
| also have interesting experiences, space-time is so distorted there
| that his clock would run arbitrarily slow and he could, therefore, in
| a subjectively short period, view an immensely long future timespan in
| the external universe."

| Seven years ago the same Martin Rees found it more profitable to
| inform the world that the source of all those extremely silly walks -
| Einstein's theory of relativity, in particular "Einstein's belief that
| the speed of light must always be the same" - should be revised:

| "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."
|
| For some time Martin Rees has been silent about Einstein's relativity.
| He knows times have changed: you cannot anymore extract money from
| worshipping this theory, you cannot extract money from revising it
| either. The world simply does not care about it. But you can extract
| money from informing the world about climate changes, and many
| Einsteinians are going in that direction. Martin Rees is just one of
| them.

Predicting the future has been the dream of charlatans since
the first shaman was tossed a bone from the hunt he was too
scared to attend.
