"Most of you are too young to remember the term future shock. Back in the seventies, some people felt that technological progress was so rapid that people, normal people, couldn't cope with it; that they wouldn't have time to get used to the present before the future was upon them. A man named Toffler coined the term future shock to describe this situation." The commodore could get pretty academic.
"We're caught up in a physical situation that resembles this scholarly concept. The result has...
Having to travel at speeds of light means facing a future version of the enemy and that you are attacking them from the past.
I like relativity and quantum theories
because I don't understand them
and they make me feel as if space shifted about
like a swan that
refusing to sit still and be measured;
and as if the atom were an impulsive thing
always changing its mind.
Einstein's equation gives us the most concrete explanation
for the central fact that nothing can travel faster than light speed. You may have wondered, for instance, why we can't take some
object, a muon say, that an accelerator has boosted up to 667 million miles per hour—99.5 percent of light speed—and "push it a
bit harder," getting it to 99.9 percent of light speed, and then "really push it harder" impelling it to cross the light-speed barrier.
Einstein's formula explains why such eff...
Because its mass will become infinite.
the precise time difference between stationary and moving clocks depends on how
much farther the sliding clock's photon must travel to complete each round-trip journey This in turn depends on how quickly the
sliding clock is moving—from the viewpoint of a stationary observer, the faster the clock is sliding, the farther the photon must
travel to the right. We conclude that in comparison to a stationary clock, the rate of ticking of the sliding clock becomes slower and
slower as it moves fas...
An elegant explanation in physical terms of photons and the distances they travel.
Imagine that George, who is wearing a spacesuit with a small, red flashing light, is floating in the absolute darkness of completely
empty space, far away from any planets, stars, or galaxies. From George's perspective, he is completely stationary, engulfed in the
uniform, still blackness of the cosmos. Off in the distance, George catches sight of a tiny, green flashing light that appears to be
coming closer and closer. Finally, it gets close enough for George to see that the light is attache...
