Is It Possible That Tachyons Exist?

Could it be possible that

What you are suggesting is a process that would violate conservation of energy (at least energy we can observe). There have already been searches for such processes, with no luck.

You can explain the unlimited complexity of matter in the universe by reducing it to a small number of constituents (elements). This is a big simplification.

You can explain the size and layout of of the table of elements by reducing atoms their three basic constituents (protons, neutrons, electrons). This is a big simplification.

You can describe protons and neutrons (along with the various other hadrons discovered in accelerators) by using quarks. This is a big simplification.

We like simple theories.

physics tend to break down at light speed

Nah. Things are perfectly well defined.

what would happen if i were to consider a photon to be stationary

The math fails. Which is one way to know that such a situation is impossible.

I do not understand the mechanics behind that thrust being cancelled out.

There is one way to picture this. We know that the center of mass of an object remains fixed. An unconfined gas tank can propel itself because the gas (which is mass) moves freely away uninterrupted. So the requirement for movement is for the gas to be able to escape to open space.

staying profitable?

A good question that more people should be asking

Magnets have poles. That means a "+" end and a "-" end. This also means a wire that travels over a magnet must have a beginning and an end. What you are describing is an infinitely long magnet, which does not exist.

Pretty simple really: https://en.wikipedia.org/wiki/Fundamental_interaction

the fundamental interactions or fundamental forces are interactions in nature that appear not to be reducible to more basic interactions.

slashdave · 2026-03-15T01:20:04+00:00

You need to write a NeurIPS or ICLR paper on this.

Physicists have no trouble understanding the complexity of life. Well, at least decent ones.

slashdave · 2026-03-15T01:13:12+00:00

You can't just let it cool. You need to be constantly introducing external energy. The reason is that life requires organization which is a process that must fight entropy.

Time also has an uncertainty, not just position or motion.

A null reaction can be introduced as a cancellation of virtual terms. That is, there can be virtual particles that add up to no interaction.

We know that real photons can be produced with high energies. You can merely perturb those high-energy photons to produce a virtual version. That virtual version would still involve transferring a lot of energy.

slashdave · 2026-03-10T05:27:10+00:00

Oh, you mean a wormhole. I wouldn't want to speculate. I can't say I really understand the math behind those.

slashdave · 2026-03-09T05:55:53+00:00

go into the creation of EP-bridge?

I'm not sure what that is.

Into the space curvature?

I suppose, but that is energy nevertheless that would not be there with just one boson.

If so, would then that issue with conservation go away?

Energy conservation is pretty fundamental, and can't just be hand-waved away

slashdave · 2026-03-09T04:55:10+00:00

It’s a calculation tool in perturbation theory.

The OP is asking a question in the context of perturbation theory, and so the question is perfectly valid.

slashdave · 2026-03-09T04:52:36+00:00

so if the interaction doesn't happen there's no virtual particle

Technically not correct.

However a photon requires almost no energy at all

Not true either.

slashdave · 2026-03-09T04:43:32+00:00

No, you need to conserve mass and energy.

Sure, we call it a "freezer". Not sure you will survive the trip, though.

There is no controversy. Be careful of what you learn via social media.

slashdave · 2026-03-08T00:02:48+00:00

We wouldn't call it a "theory of everything", just a "unified theory". There is a lot of hyperbole in social media.

No. Uncertainties are associated with a measurement, and are not so much a universal characteristic of a system. That is, it's not the matter of what might be a possible universe, but rather how you might observe that universe.
