Do superluminal particles exist?

However, it was soon realized that Feinberg’s model did not in fact allow for superluminal (faster-than-light) speeds. The complementary particle types are called luxons (which always move at the speed of light) and bradyons (which always move slower than light); both of these particle types are known to exist.

Is FTL theoretically possible?

According to the current scientific theories, matter is required to travel at slower-than-light (also subluminal or STL) speed with respect to the locally distorted spacetime region. Apparent FTL is not excluded by general relativity; however, any apparent FTL physical plausibility is currently speculative.

Can we detect neutrinos?

Despite how common they are, neutrinos are extremely difficult to detect, due to their low mass and lack of electric charge. In a neutral current interaction, the neutrino enters and then leaves the detector after having transferred some of its energy and momentum to a ‘target’ particle.

What device detects charged particles but does not show their tracks?

Research particle detectors The term counter is often used instead of detector when the detector counts the particles but does not resolve its energy or ionization. Particle detectors can also usually track ionizing radiation (high energy photons or even visible light).

Can tachyons be detected?

Could we ever detect them? Aside from the fact that like other particles, they are likely incomprehensibly tiny, because tachyons always travel faster than light it isn’t possible to detect one on its approach. That’s because it’s moving faster than any associated photons.

Do tachyon particles 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.

Does Tachyon 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.
