Now make the assumption that we cannot travel faster than light but

The time-dilation then takes effect.
Does this not mean that future astronaughts may be on a one-way trip
into the future and never see their families again? Also, it could
mean one could indefinately go forward in time. Just return home and
set-out again faster still with newer technology having made a pact
with future generations.You need only gain 50 years per trip - it
would soon mount up.

Before you swallow the whole hook line and sinker you might
ask the source of such notions to explain how inertial
motion affects the invariant mass or torque of this simple
mechanism:

"Torsion Pendulum" [URL corrected]

Only "Sue" would dance along a jargon string, led by web search
strings:
special relativity --> inertial frames --> inertia --> moment of
inertia --> torsion pendulums. And then imagine that special
relativity is about torsion pendulums.

<< The key to understanding special relativity is
Einstein's relativity principle, which states that

    All inertial frames are totally equivalent for the
performance of all physical experiments.

In other words, it is impossible to perform a physical
experiment which differentiates in any fundamental
sense between different inertial frames. By definition,
Newton's laws of motion take the same form in
all inertial frames. Einstein generalized this result in
his special theory of relativity by asserting that all laws
of physics take the same form in all inertial frames.>>

So you too, are invited to help some of your fellow
"advocates of nonsense"  explain how Hooke's
law is modified by inertial morion.

I'm sorry... Hooke's "law" is not really a law of physics, any more
than Ohm's "law" is. It is a description that holds in a broad class
of cases, just like Ohm's law does, but it is really no more than
keeping the first-order term in a Taylor expansion about *any*
potential about a local minimum.

Then the impedance of free-space isn't really  377 ohm?

No, I'm not saying that, and that doesn't have anything to do with
Ohm's law.
Here again your internet search keyword free association game lead you
down into little rabbit warrens in the weeds and you have no idea how
you got there.
First it was special relativity -> inertial reference frame -> inertia
-> moment of inertia -> torsion pendulum
Now it's Ohm's law -> resistance -> impedance -> impedance of vacuum -
Maxwell's equations -> law of physics.
As I said, if you try harder, you'll be able to associate special
relativity with Kevin Bacon, as that's only six degrees of separation,
a well-known law of physics.


I think you are saying inertial motion revokes Hooke's law.

No I'm not saying that at all. Your ability to comprehend anything
other than free association of internet search terms is a bit on
the ... unaccomplished end of the scale.


While that certainly   unique among your fellows advocates
I think you will find your logic refuted where
the product of eps and mu are factors in the constancy
of light speed.http://farside.ph.utexas.edu/teaching/em/lectures/node108.htm
