TACHYONS: faster-than-light particles
Particle that Travels faster than Light !
According to the Theory of Relativity, more specifically The
Special Theory of Relativity, proposed by Albert Einstein in 1905, nothing can
travel faster than light. Speed of the light is the extreme speed in this
universe. And the speed of the light in vacuum is the same for all observers,
in every direction. Photon, which is the unit element of light, is the
speediest particle in this universe.
But is this the end of the science about speediest particle
?
No, Scientists were never satisfied. They found another
particle that travel faster than light. The name of the particle is Tachyon.
HISTORY: Tachyons
were first proposed by physicist Arnold Sommerfeld in 1904 and later it was
found by O.M.P. Bilaniuk, V.K. Deshpande and the Indian scientist E.C.G.
Sudarshan in 1962. The term “tachyon” coined by Gerald Feinberg in a paper titled “Possibility
of Faster-Than-Light Particles” in 1967. He had been inspired by the
science-fiction story “Beep” by James Blish. Tachyons are studied in an area of
physics called ‘Particle Physics’.
TACHYON
Tachyons are hypothetical particles. It never been proved by
experiments. But some scientists believe in the existence of tachyon, because
of gravity. Most of the physicists don’t believe that faster-than-light
particles can exist as they violate the known laws of physics. If such
particles do exist, they can be use to build a tachyonic antitelephone. We
just predict theoretically that tachyon like objects can exist. And the most interesting
fact is that tachyon particle has mass.
NEUTRINOS
Physicist Chodos proposed that neutrinos can have a tachyonic
nature at high energies, in 1985. It means, according to him, neutrinos can travel
faster than light at a high range of energy.
If Tachyons exist :
i) According to theories, tachyon has a curious property
that is for some observers tachyon travels backwards in time.
ii) Tachyons may can escape the interior of the Black Hole.
And so on…
We can predict many more things about tachyons. If we can
prove the existence of tachyon, we will be one more step ahead in time
travelling.
