Are Tachyons real?

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

faster-than-light

Superluminal communication is a hypothetical process in which information is sent at faster-than-light (FTL) speeds. The current scientific consensus is that faster-than-light communication is not possible, and to date it has not been achieved in any experiment.

'quasiparticles' moving through laser-like media.

Why can't tachyons exist?

A tachyon (/ˈtækiɒn/) or tachyonic particle is a hypothetical particle that always travels faster than light. Physicists believe that faster-than-light particles cannot exist because they are not consistent with the known laws of physics.

Do tachyons travel back in time?

The tachyon is created on the "now" hypersurface of simultaneity and propagates towards the "earlier" hypersurface of simultaneity. It arrives at the earlier hypersurface that collects events from an earlier time before it was created. That means that the tachyon is traveling backwards in time.

Are tachyons theoretical?

Tachyons are one of the most interesting elements arising from Einstein's theory of special relativity. The 1905 theory is based on two postulates, nothing with mass moves faster than the speed of light (c), and physical laws remain the same in all non-inertial reference frames.

Can tachyon escape 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.

Is Dark Matter real?

The phenomenon is called gravitational lensing. By studying how light is distorted by galaxy clusters, astronomers have been able to create a map of dark matter in the universe. A vast majority of the astronomical community today accepts that dark matter exists.

Is time Travelling possible?

Yes, time travel is indeed a real thing. But it's not quite what you've probably seen in the movies. Under certain conditions, it is possible to experience time passing at a different rate than 1 second per second. And there are important reasons why we need to understand this real-world form of time travel.

How do you detect tachyons?

Tachyons would still have mass-energy, so in principle, they could be detected through their gravitational field. Beyond that, they might be detectable if they interacted nongravitationally with other forms of matter.

Can God travel faster than light?

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. It merely reinforces the knowledge that light travels very fast indeed.

Do wormholes exist?

Wormholes are shortcuts in spacetime, popular with science fiction authors and movie directors. They've never been seen, but according to Einstein's general theory of relativity, they might exist.

Does darkness have a speed?

Darkness travels at the speed of light. More accurately, darkness does not exist by itself as a unique physical entity, but is simply the absence of light. Any time you block out most of the light – for instance, by cupping your hands together – you get darkness.

How fast does Hawking radiation travel?

Hawking radiation is an incredibly slow process, where a black hole the mass of our Sun would take 10⁶⁷ years to evaporate; the one at the Milky Way's center would require 10⁸⁷ years, and the most massive ones in the Universe could take up to 10¹⁰⁰ years!

Can antimatter travel faster than light?

The only (anti)particle that can travel at the speed of light (but not faster than that) is light itself, namely photon field. Since photon is its own anti particle, we can conclude that the only anti-matter travelling at speed of light is 'light.

How fast is tachyon speed?

Named after the theoretical particle that moves faster than light, the Tachyon Speed has a claimed top speed exceeding 240mph and has a 0-60mph figure of three seconds. Power comes from six direct-drive electric motors, which develop 1,250bhp and 4,949 Nm torque.

Is a neutrino faster than light?

If it's true, it will mark the biggest discovery in physics in the past half-century: Elusive, nearly massless subatomic particles called neutrinos appear to travel just faster than light, a team of physicists in Europe reports.

Is light faster than darkness?

Darkness Is Faster Than the Speed of Light.

Is the Higgs boson a tachyon?

Once the tachyonic field reaches the minimum of the potential, its quanta are not tachyons any more but rather are ordinary particles with a positive mass-squared, such as the Higgs boson.

What is the tachyon device?

The tachyon prototype is a device developed by Mercury Labs that can absorb the Speed Force.

Does the past still exist?

In short, space-time would contain the entire history of reality, with each past, present or future event occupying a clearly determined place in it, from the very beginning and for ever. The past would therefore still exist, just as the future already exists, but somewhere other than where we are now present.

Is time an illusion?

According to theoretical physicist Carlo Rovelli, time is an illusion: our naive perception of its flow doesn't correspond to physical reality. Indeed, as Rovelli argues in The Order of Time, much more is illusory, including Isaac Newton's picture of a universally ticking clock.

What is inside a black hole?

The singularity at the center of a black hole is the ultimate no man's land: a place where matter is compressed down to an infinitely tiny point, and all conceptions of time and space completely break down. And it doesn't really exist.

Can dark matter give you superpowers?

User can to create or wield weaponry with power over dark matter, which grants the user a wide variety of dark matter-based abilities, including generation, transmutation, and creation of constructs, along with volatile abilities involving normal universal matter or antimatter.

Why is space dark?

Because space is a near-perfect vacuum — meaning it has exceedingly few particles — there's virtually nothing in the space between stars and planets to scatter light to our eyes. And with no light reaching the eyes, they see black.

Can dark matter touch?

When we look out into the universe, we don't know what we're looking at for the most part. In fact, we can't even see most of what we're looking at – that's because the majority of the universe is made up of mysterious, practically invisible dark matter.
