all died off. Some paleontologists thought that maybe a meteor from
space had killed them, but that was impossible, more in the realm of
science fiction.
Today we now know that through plate tectonics the continents do
move, and that 65 million years ago a gigantic meteor measuring six
miles across most likely did obliterate the dinosaurs and much of life
on Earth. In my own short lifetime I have seen the seemingly impossible become established scientific fact over and over again. So is it impossible to think we might one day be able to teleport ourselves from
one place to another, or build a spaceship that will one day take us
light-years away to the stars?
Normally such feats would be considered impossible by today's
physicists. Might they become possible within a few centuries? Or in
ten thousand years, when our technology is more advanced? Or in a
million years? To put it another way, if we were to somehow encounter
a civilization a million years more advanced than ours, would their
everyday technology appear to be "magic" to us? That, at its heart, is
one of the central questions running through this book; just because
something is "impossible" today, will it remain impossible centuries or
millions of years into the future?
Given the remarkable advances in science in the past century, especially the creation of the quantum theory and general relativity, it is
now possible to give rough estimates of when, if ever, some of these
fantastic technologies may be realized. With the coming of even more
advanced theories, such as string theory, even concepts bordering on
science fiction, such as time travel and parallel universes, are now being re-evaluated by physicists. Think back 150 years to those technological advances that were declared "impossible" by scientists at the
time and that have now become part of our everyday lives. Jules Verne
wrote a novel in 1863, Paris in the Twentieth Century, which was
locked away and forgotten for over a century until it was accidentally
discovered by his great-grandson and published for the first time in
1994. In it Verne predicted what Paris might look like in the year 1960.
