Do Tachyons really exist?

Do Tachyons really exist?

Tachyons have never been found in experiments as real particles traveling through the vacuum, but we predict theoretically that tachyon-like objects exist as faster-than-light 'quasiparticles' moving through laser-like media. ... "We are beginning an experiment at Berkeley to detect tachyon-like quasiparticles.

Who found Tachyons?

Gerald Feinberg Tachyons were first introduced into physics by Gerald Feinberg, in his seminal paper "On the possibility of faster-than-light particles" [Phys.

Do Tachyons have negative mass?

Instead, the negative mass represents an instability to tachyon condensation, and all excitations of the field propagate subluminally and are consistent with causality. Despite having no faster-than-light propagation, such fields are referred to simply as "tachyons" in many sources.

Can a tachyon escape a black hole?

Since the disturbance of a localized tachyon cannot spread faster than c, it therefore cannot escape the inside of a black hole's event horizon.

Can God travel faster than light?

A few years ago, a group of physicists posited that particles called tachyons travelled above light speed. ... It seems, so far, that no object has been observed that can travel faster than the speed of light. This in itself does not say anything at all about God.

Can tachyons escape a black hole?

And the answer to your question for this kind of tachyon is that it cannot escape a black hole.

Could a human survive a black hole?

Even light, the fastest-moving thing in our universe, cannot escape – hence the term “black hole.” The radial size of the event horizon depends on the mass of the respective black hole and is key for a person to survive falling into one. ... A person falling into a supermassive black hole would likely survive.

Will our Sun become a black hole?

However, the Sun will never turn into a black hole, because it is said to have less mass than needed to turn into one. When the Sun is about to reach its end and run out of its fuel, it will automatically throw off outer layers turning into a glowing gas ring known as a “planetary nebula”.

What is the fastest thing in the universe?

Laser beams Laser beams travel at the speed of light, more than 670 million miles per hour, making them the fastest thing in the universe.

Can a tachyon travel faster than the speed of light?

• Because a tachyon would always travel faster than light, it would not be possible to see it approaching. After a tachyon has passed nearby, an observer would be able to see two images of it, appearing and departing in opposite directions. The black line is the shock wave of Cherenkov radiation, shown only in one moment of time.

Who is Raymond Chiao and what are tachyons?

• Raymond Y. Chiao is professor of physics at the University of California, Berkeley. He replies: "Briefly, tachyons are theoretically postulated particles that travel faster than light and have 'imaginary' masses.

Why do scientists believe in quasiparticles like tachyons?

• There are strong scientific reasons to believe that such quasiparticles really exist, because Maxwell's equations, when coupled to inverted atomic media, lead inexorably to tachyon-like solutions. "Quantum optical effects can produce a different kind of 'faster than light' effect (see "Faster than light?"

Is the time of annihilation of a tachyon frame dependent?

• (At infinite speed, the two tachyons have no energy each and finite momentum of opposite direction, so no conservation laws are violated in their mutual annihilation. The time of annihilation is frame dependent.)
