Luttgens:
You are claiming that time on SN is dilated wrt time on Earth,

Feuerbacher:
I am claiming that the time on SN *at the time when the light was
emitted* *looks* dilated. Due to the expansion of space which happened
since the emission of the light. Nothing more.

Luttgens:
You should specify that it "looks" dilated by a factor f *to an Earth
observer*.
And you are forgetting that the time on Earth *at the time when the
light was emitted* *looks* dilated by the same factor f *to a supernova
observer*. This is a mere consequence of the Cosmological Principle,
according to which all positions in the universe are essentially
equivalent.

Mathematically, for an Earth observer, to a time interval t(earth)
corresponds a time interval
(1) t(supernova) = t(earth) * f, and symmetrically, for a galactic observer,
t(earth) = t(supernova) * f,
where f is the same time dilation factor. By replacing this
value of t(earth) in relation (1), one gets
t(supernova) = t(supernova) * f^2, which is only possible if f = 1.
Thus relation (1) reduces to t(supernova) = t(earth), meaning
that, contrary to the claim made by contemporary cosmologists, no
"time dilation factor works on supernovae to lessen the delay in
the rest frame".

Hm, that sounds like the "Famous Devastating Marcel Luttgens
Special Relativity Refutation", going like this:
| t' = gamma * t for a clock at rest in the unprimed frame
| and
| t = gamma * t' for a clock at rest in the primed frame
| and therefore
| t' = gamma^2 * t'
| which is only possible if
| gamma = 1
Sounds familiar, Marcel?

Contemporary cosmologists, who base their claim on general
relativity, are simply wrong.

Of course, since the Refuted Luttgens Version of Special Relativity
is a special case of the Luttgens Version of General Relativity, the
latter is automatically refuted as well, right, Marcel?

Well done, Marcel - brilliant come-back, Marcel!

And you see, I can copy-paste as well, remember, Marcel?
However, I changed one little detail - can you find it, Marcel?

Don't worry about that. He has v c in mind, since
he perfectly knows that he does not understand even
the first letter of special relativity -- for starters, ask
him about events and coordinates. That's why he is
having a go now at the *much* simpler theory of
general relativity now ;-)

"Fumbling" Dirk is unable to realize the consequence of space
expansion, i.e. that galaxies move apart *from each other*.
Iow, when galaxy A moves wrt galaxy B, the opposite is phyically
true: galaxy B moves wrt galaxy A. Hence, when A observes a
time slowing on B, B necessarily observes the *same* time
slowing on A. SRists, like "Fumbling" Dirk, who claim against

I give you the chance to clarify your position:

In order to verify the validity of Einsteinian relativity, the NASA
decided to perform the following experiment, where two jet aircrafts
flying in opposite directions would each follow the same meridian.
The departure and arrival airport would be situated exactly on
the equator. The two aircrafts would climb at exactly the same rate
till their cruising altitude of about 10000 feet, and keep the
same speed of about 900 km/h. The whole experiment would thus last
about 44 hours.
At lift-off, the two aircrafts would synchronize their clocks.
At landing, they would compare the reading of the clocks.

In view of the fundamental importance of the experiment, the NASA
chose as pilots two distinguished relativists, "Fumbling"
Dirk and Björn "the GRist".

On D-day, at local time T, the two aircrafts took off.
About 5 hours after the take off, the NASA scientist asked the
two pilots if they thought that their clocks were still synchronized.

"Fumbling" Dirk automatically replied: "Of course not, according to
the Lorentz transformation, and assuming that the Earth is homogeneous
and perfectly spherical, time on Björn's plane is dilated,
hence its clock is now slow wrt my clock. So, at landing, we
should observe a time difference between the two clocks."

Björn "the GRist", very carefully replied: "Well, there is no
absolute time, the clock readings depend on the frame of reference.
Dirk is perfectly right to claim that my clock slowed down,
but I am also perfectly right to claim that his clock is now
slow wrt my clock. I don't know if the two clocks are now ticking
at the same rate, but they could nevertheless show the same time
at landing.". Alas, the NASA scientist couldn't make out the
meaning of such obscure utterance.

Needless to say that at landing, the two clocks showed exactly the
same time.

At landing, they would compare the reading of the clocks.

In view of the fundamental importance of the experiment, the NASA
chose as pilots two distinguished relativists, "Fumbling"
Dirk and Björn "the GRist".

On D-day, at local time T, the two aircrafts took off.
About 5 hours after the take off, the NASA scientist asked the
two pilots if they thought that their clocks were still synchronized.

"Fumbling" Dirk automatically replied: "Of course not, according to
the Lorentz transformation, and assuming that the Earth is homogeneous
and perfectly spherical, time on Björn's plane is dilated,
hence its clock is now slow wrt my clock. So, at landing, we
should observe a time difference between the two clocks."

Björn "the GRist", very carefully replied: "Well, there is no
absolute time, the clock readings depend on the frame of reference.
Dirk is perfectly right to claim that my clock slowed down,
but I am also perfectly right to claim that his clock is now
slow wrt my clock. I don't know if the two clocks are now ticking
at the same rate, but they could nevertheless show the same time
at landing.". Alas, the NASA scientist couldn't make out the
meaning of such obscure utterance.

Needless to say that at landing, the two clocks showed exactly the
same time.
