Meira heilafóður, útskýrt á mannamáli. Og ég, eins og fyrr,
mun ekki þýða þetta. Þetta er flott eins og það er. Ef þú kannt
ekki ensku, þá skiluru hvort sem er ekkert um hvað þetta er :D

Appearance of Special Relativity Theory: Light does not move
at a constant speed in vacuum. However, light-based
observations will give the appearance of such a
phenomenon.
According to Einstein's Theory of Special Relativity, objects
experience time, mass, and length dilation based on their
relative velocities because light always moves at the same
speed, c, unless acted on by moving through a material or a
gravitational field. The series of equations used to explain
time dilation is based on that premise. However, we have to
remember that if light doesn't move at a constant speed, but
is instead emitted and/or reflected at a constant speed, it will
create the illusions of dilation. For example, an object moving
away from you at .5c appears to have a slower rate of time
than you do, because its light has to travel farther and farther
to get to you; to it, you look the same way. This is called the
Clock Paradox, and has been used as a cheap excuse to
make forward time travel sound plausible. Move at near-light
speeds and time goes slowly. But that's not the case, since
time would have to go equally slowly for the rest of the
universe when compared to you. But basically, by the time you
returned, nothing would have changed timewise, since even if
time dilation could exist, any shifts would be negated in the
process of returning to your point of origin.
Some people will tell you that the Clock Paradox has been
proven. It isn't possible. Not remotely. Any evidence is based
on observations using guess what- light! Or at least variations
of light, which may be susceptible to the very same quirks of
physics as light itself.
Sorry, Al, but you were wrong on that one.
