Why is it "absurd"?

It's as absurd as believing that you can draw a student a round square.
As the student does not succeed, we blame the pencil, then we blame
the paper.

That is another irrelevant mumble. You need to have a cogent argument,
not mumbling a false comparison.

... but the student still does not know how to draw a round square.

Tachyons aren't round squares. Irrelevant simile.

This is what is happening with the speed of light speed, or body
propagation or physical laws.

No, it's not. Energy and momentum are the basis, not round squares
or an undefined Vo. The basic relationship is E^2 - p^2c^2 = m^2c^4
m^2 positive: bradyons, 0 < v < c; m^2 zero: luxons (photons); v = c
m^2 negative: tachyons, c < v < infinity -- completes the symmetry.

We simply cannot.

We simply can, even if you cannot.

[Irrelevant baloney deleted.]

It is simply as illogical, in OUR UNIVERSE, as to return before having
left, or to go faster than an instantaneous interaction.

Tachyons can't do that, so this assertion is irrelevant, too.

It's only "no closed time-like curves",
doesn't say anything about "no linear
Galilean motion", Relativity Theory.

Photinos and the Aspect-type experiments
after J.S. Bell and that, you know,
helps remind that Cerenkov and so on,
is, faster than light in a medium, ....

Of course the sky survey and Wiki is full
of "apparent superluminal motion" these days.

Einstein's Relativity Theory, ....
