LSU professor resolves Einstein's twin paradox
BATON ROUGE -- Subhash Kak, Delaune Distinguished Professor
of Electrical and Computer Engineering at LSU, recently
resolved the twin paradox, known as one of the most
enduring puzzles of modern-day physics.
First suggested by Albert Einstein more than 100 years ago,
the paradox deals with the effects of time in the context
of travel at near the speed of light. Einstein originally
used the example of two clocks -- one motionless, one in
transit. He stated that, due to the laws of physics, clocks
being transported near the speed of light would move more
slowly than clocks that remained stationary. In more recent
times, the paradox has been described using the analogy of
twins. If one twin is placed on a space shuttle and travels
near the speed of light while the remaining twin remains
earthbound, the unmoved twin would have aged dramatically
compared to his interstellar sibling, according to the
paradox.
"If the twin aboard the spaceship went to the nearest star,
which is 4.45 light years away at 86 percent of the speed
of light, when he returned, he would have aged 5 years. But
the earthbound twin would have aged more than 10 years!"
said Kak.
The fact that time slows down on moving objects has been
documented and verified over the years through repeated
experimentation. But, in the previous scenario, the paradox
is that the earthbound twin is the one who would be
considered to be in motion -- in relation to the sibling --
and therefore should be the one aging more slowly. Einstein
and other scientists have attempted to resolve this problem
before, but none of the formulas they presented proved
satisfactory.
Kak's findings were published online in the International
Journal of Theoretical Science, and will appear in the
upcoming print version of the publication. "I solved the
paradox by incorporating a new principle within the
relativity framework that defines motion not in relation to
individual objects, such as the two twins with respect to
each other, but in relation to distant stars," said Kak.
Using probabilistic relationships, Kak's solution assumes
that the universe has the same general properties no matter
where one might be within it.
The implications of this resolution will be widespread,
generally enhancing the scientific community's
comprehension of relativity. It may eventually even have
some impact on quantum communications and computers,
potentially making it possible to design more efficient and
reliable communication systems for space applications.
