I think it's time to have a rational discussion of tachyonic communication and the limitations thereof. DOI: 10.13189/ujpa.2023.170101 present a proof that tachyons, even if they existed, could not violate causality by sending a message into the past.Some of the salient points in that paper are listed below.
(1) The four-momentum formalism (4MF) isn't immune from criticism because it's declared to be a "definition. Nature doesn't care about what humans assert.
(2) By (1), the 4MF, particularly its transformation into other inertial frames, must be justified only if it can be derived from more basic considerations.
(3) The basic energy equation, which can be derived from Lagrangian mechanics, is E = mc^2/(1 - u^2/c^2)^0.5. For tachyons, m --> im.
(4) E = imc^2/(1 - u^2/c^2)^0.5 is the accepted relationship for tachyons.
(5) E' = imc^2/(1 - u'^2/c^2)^0.5, where u' = (u -v)/(1 - uv/c^2).
(6) Equivalently, E' = mc^/(u'^2/c^2 - 1)^0.5
(7) E' never becomes negative for ANY real value of u', therefore the 4MF
is invalid for tachyons when u > c^2/v. For u < c^2/v, tachyons are detectable by a stationary receiver, and there is no causality violation described by Method I.
(8) u' becomes asymptotic as u approaches c^2/v. Going beyond that
is mathematically inappropriate.
(9) Tachyons with u > c^2/v can be detected by moving the receiver
toward the tachyon source such that u' < c^2/v, which converts the
situation to Method II.
(10) Claims that Method II violates causality are based on switching
frames in the middle of solving the problem. Figures 4 and 5 in
DOI: 10.13189/ujpa.2023.170101 show that the two frames disagree
with the position of the observers, which is due to the relativity of simultaneity. THAT is why switching frames in the middle leads to
incorrect conclusions, namely causality violation.

If they are detectable why are the no detected in certainty?How long did it take to verify that neutrinos really existed? There's the answer
to your question. The point of the paper is not whether tachyons exist, but that even if they do, they cannot send messages into one's past. This is important because nearly all physicist who discuss tachyons claim that they can, and use that to claim that they cannot exist.
There is no evidence for them coming back from the future...And there never will be, as DOI: 10.13189/ujpa.2023.170101 demonstrates

(8) u' becomes asymptotic as u approaches c^2/v. Going beyond that

Right. Negative Gamma has never belonged.There is no "negative gamma" in relativity (the square root of a negative number is not negative). In the derivation of the relativistic velocity equation, the gammas cancel out, leaving u' = (u - v)/(1 - uv/c^2), which CAN become negative if uv/c^2 is greater than 1. Note that in
E' = mc^2/(u'^2/c^2), negative u' values do not produce negative values
for E', which the 4MF does.

I'm sure you're aware of the recent history of the attempt to discover the mass of the electron antineutrino from tritium decay:

3M. Aker et al.,”Improved Upper Limit on the Neutrino Mass from a Direct Kinematic Method by KATRIN,” Phys. Rev. Lett. 123, 221802 (2019)
The value obtained from the Mainz experiment was M^2 = -0.6 eV^2,
indicating that the mass was imaginary (indicating a tachyon), but the
error bars were +/- 4.3 eV^2. The initial results from KATRIN were more encouraging: -1.0 +0.9-1.1 eV^2, indicating a significant probability that the mass of the electron antineutrino is imaginary.
The more recent KATRIN result is less encouraging, however, because
their new value is +0.26 +/-0.34 eV^2, but still with about a 20% probability that the mass is imaginary. I read somewhere that this last value was obtained by rejecting some of the data because it was "unphysical," but I'm not making any any accusations at this point.
There is a lot of older papers hypothesizing that neutrinos might be tachyons,
but we'll see how KATRIN does in its ongoing experiment.

All of those are compatible with zero mass of neutr[ino].
Even if a neutrino] were a tachyon it's speed is so close to the speed of light that
for communication purposes it does not make a difference.

Yes, the error bars include zero, but neutrino flavor oscillation proves that it's NOT
zero.

MikkoNeutrinos are produced by nuclear interactions so their energies are quite high;
however, there are ways to reduce their energies. For example, move the source
away from the receiver: u' = (u - v)/(1 - uv/c^2), as v --> c^/u, u' approaches \infty.
As u' --> \infty, E' --> 0. The source would be particles in an accelerator undergoing
a decay process that creates neutrinos.
Detecting them is still a problem, though. We don't know how to detect the low-
energy neutrinos produced by stars in galaxies moving away from us at, say, z = 10 :-(

Indeed.
A few moments of thought would show that for a tachyon, with imaginary
mass, to be emitted by a particle of ordinary matter with real mass, the tachyon cannot be emitted singly, but rather as one of a pair of tachyons with opposite imaginary sign, otherwise the emitting particle would be left with complex valued mass, which quite frankly, gives me a headache to
try to imagine what properties it might have.
However, in beta emission, neutrinos are emitted singly. Therefore, neutrinos are not tachyons. Neutrino masses must be real-valued.

In physics, it seems to me that energy is the quantity that is important, not mass.
This was pounded into my head during my Orals and, of course, I've never forgotten it. Conservation laws are the sine qua non of physics, and I can't think
of any conservation law that would apply to mass since it is equivalent to energy.
Can you?
As a contrary example, two particles which have m > 0 (bradyons) can interact
and create two particles which have m = 0 (luxons). It's energy and spin that's
conserved, not type of mass.
Got any more misgivings?

As a contrary example, two particles which have m > 0 (bradyons) can interact
and create two particles which have m = 0 (luxons). It's energy and spin that's
conserved, not type of mass.

with complex valued mass, which quite frankly, gives me a headache to try to imagine what properties it might have.
However, in beta emission, neutrinos are emitted singly. Therefore, neutrinos are not tachyons. Neutrino masses must be real-valued.
Hi PCH, I'm glad you decided to contributed to the discussion.
In physics, it seems to me that energy is the quantity that is important, not mass.
This was pounded into my head during my Orals and, of course, I've never forgotten it. Conservation laws are the sine qua non of physics, and I can't think
of any conservation law that would apply to mass since it is equivalent to energy.

How can a single neutrino of supposedly complex mass be emitted in
beta decay rather than a neutrino antineutrino pair? As you state, mass-energy needs to be conserved, and is is true even if mass is complex.
It's also rather interesting if you draw a spacetime diagram illustrating how an FTL particle and a normal particle might interact. I'm sure that Mikko on this thread would know what I am getting at, in addition to an unknown number of lurkers.

Consider my Figure 3-12a section in "Energy_and_momentum_conservation" https://en.wikipedia.org/wiki/Spacetime#Energy_and_momentum_conservation
I drew this in the rest frame of the negative pion. The pion decays into a muon,
emitting an antineutrino. To conserve momentum, the muon has an equal and opposite momentum as that of the antineutrino. If, as you suppose, the antineutrino were a tachyon, its momentum would be imaginary. Therefore the muon's momentum would also be imaginary, which doesn't make any sense.
Muons are not tachyons.
If you explore spacetime diagrams further, you would see that a general implication of the hypothesis that tachyons could be absorbed or emitted by matter would be that tachyons trigger matter instability. I'll leave you to work
out why this must be so.
*Scattering* of tachyons without absorption remains a possibility, as would decay of matter into tachyon *pairs". But since the tachyons would be undetectable, decay of a particle into a tachyon pair would mean that so far as our instruments could tell, a particle of matter would have winked out of existence.

Not so, Prok. Certainly, tachyon mass is imaginary, and p = mv/sqrt(1 - v^2/c^2).
However, since v > c, the denominator is also imaginary, which cancels out the
imaginary in the numerator. Thus tachyon momentum is real, not imaginary.
This was discussed by Bilaniuk et al in their seminal paper over 60 years ago.

have real energy and real momentum.

I thought we had settled the issue of "invisible" tachyons with your last post.
Even if their velocity is beyond the c^2/v limit, they can still be detected.
The method is to move the receiver toward the tachyon source, of course. Then
the
tachyons will have real, positive energy with respect to the receiver. The observer
can then interrogate the receiver and find that nothing has "winked out of existence."
It's analogous to the case where a beta decay in tritium occurs, wherein a neutron
decays creating a proton and an electron -- but the conservation of energy and
momentum demands the existence of a third "invisible" particle to balance conservation
requirements. We don't have the means to detect that third particle, but that
doesn't
mean that particle is nonexistent. If we had the proper instrumentation, we would detect
it.

Tachyons do[es] not exist.

“If at first the idea is not absurd, then there is no hope for it.” -- Albert Einstein
Speak for yourself, Doctor Hachel :-))
There are two kinds of absurdities, certain absurdities, and apparent absurdities.
Saying “there are tachyons”, “there are round squares”, “There is a number between 8 and 9”, these are certain absurdities.
round squares”
To say as Hachel says: "Sometimes the whole can be less than the sum of
the parts", is only an apparent absurdity.
If I take for example all the small segments of proper time during an accelerated trip to Tau Ceti (x=12ly, a=1.025ly/y²) and add them up, I
get the total proper time of the trip. But on the other hand, if I take
all the small improper time segments (terrestrial time), I notice with amazement that the sum of the time segments is greater than the totality
of the measured time.
This seems absolutely absurd, and I am absolutely certain that physicists around the world would give up if I spoke to them like that.
Yet this absurdity is only apparent.
Doctor Hachel is right.
The problem then becomes human: "Other people don't think like me.
THEREFORE he's a moron."
Where is the rule for judging?
Theoretical beauty, theoretical precision, clear explanations,
experimental proofs? I have all that, more than them.
This story of tachyons is physically absurd,
and the abstract idea that we have of it, and that we believe
we can impose, shows that we are in complete ignorance.

The more recent KATRIN result is less encouraging, however, because
their new value is +0.26 +/-0.34 eV^2, but still with about a 20% probability that the mass is imaginary.

That's an important point because a conventional view held by most physicists is that they cannot exist because they DO violate causality.

The issue is not the definition of effective mass (which I gave you multiple times),
The issue is that m_neutrino is not equal to sqrt (m_nu^2).
But you are too of a gardened crank to learn that.

Is Dono asserting that 1/(1 - uv/c^2) at the limit of u --> c^2/v is "natural"?
Quite the opposite, I have been pointing out to you that it leads to unphysical situation.

The "predicament" is that tachyons do not exist.
It is the tachyons that are not real.
We have been over this multiple times, the four momentum formalism when applied
to tachyons exposes the fact that energy jumps from +infinity to -infinity.

which approaches zero as u --> c^2/v and ignorantly and arrogantly claims the
above.
No, it doesn't "approach zero", crank. It has an asymptote from plus to minus infinity.
That represents the limit to the domain of applicability for the RVC,
Crank,
You keep trying to patch up your insanities by restricting the domain of relative speed between inertial frames as a function of tachyon speed.
That was the first and very glaring crankery I rubbed your nose in.
So the domain of applicability of the RVC equation doesn't extend to regions
where u' goes to infinity.
