One can also not know that which is.  Which is the case with you here.

You are arguing out of your ignorance of what has been observed.  Such an 
argument is a fallacy; your reasoning is flawed.

If simple logic is a “dogma”, then I am content with you calling the result 
of its application “dogma”.  You have not the slightest clue what you are 
talking about.

No, about consistency.  If the basic principle of relativity holds, and that 
it holds has been confirmed since Galilei, then all observers must agree on 
the outcome of an experiment.  In this case, the number of atmospheric muons 
that are *measured* (or whose predicted effects are measured – that does not 
make any difference) to reach the surface of Earth.

Read <http://hyperphysics.phy-astr.gsu.edu/hbase/Relativ/tdil.html>, then 
select “Application in muon decay experiment” further below (you will find a 
picture there, so even you should be able to understand it).

That's true. It's clear that you don't know you're stupid.

It's not. Your fantasy based on unjustifiable assumptions and invalid
conclusions is a dogma.

You'd be wrong to do that. Even with simple-minded logic.

Wrong again, Pointy Head. It's you who have no idea what I'm talking
about. Let me inform you: no-one has ever observed length contraction.

Note the word "observed", you braindead boob. Look it up in a
dictionary. Try to work out what "observed" really means.

You're a moron: the effects detected at the ground are assumed
to be the effects of the very same phenomena as those detected
at altitude.

I presume you're not quite stupid enough to try to tell me that
the experiment tracked them all the mat down to the ground?

No, we *know* that there are elementary particles that have the same 
properties as electrons except slightly greater mass, that we call “mu 
leptons”, or “muons” for short.  We know *precisely* how they interact, how 
they decay, and we can measure the decay products.  So we *can* *measure* 
muons.  You could have known that had you bothered to read what I referred 
to:

What a nonsense.

There are different ways to formulate it.  For example:

A) The laws of mechanics are the same in every inertial reference frame.

B) There is no preferred inertial reference frame.

(That you do not even know *that* is evidence that you have no idea what you 
are talking about.)

> Pointy Head.?

That is neither my name nor my nickname.  Your childish attempts at 
insulting me are pointless and ridiculous.
 
>> and that it holds has been confirmed since Galilei,
> 
> Oh? So you're talkin g about Galilean relativity, are you?

Of course.  The special principle of relativity as stated by Einstein in 
1905 is but an extension of the Galilean (“basic”) principle of relativity:

It states that not only the laws of mechanics, but *all* laws of physics, 
including Maxwell’s laws of electrodynamics, are the same in every inertial 
reference frame. (postulate #1)

It additionally raises the thesis of Maxwell’s electrodynamics, supported by 
prior observations, that the speed of light c is the same for all observers 
(in all reference frames), and therefore does not depend on the motion of 
the light medium relative to the observer – c = 1∕√(ε₀ µ₀ ε_r µ_r); ε₀, µ₀, 
ε_r, µ_r are constants, so must be c –, to a principle (principle of light 
constancy). (postulate #2)

From that follow the *observed* special-relativistic effects: relativity of 
simultaneity, time dilation, and length contraction; and the *observed* 
effects that follow from that (like the unexpected outcome of the Fizeau 
experiment about 50 years earlier, and the Michelson–Morley experiment about 
15 years earlier).  And they are ultimately succinctly expressed in and 
predicted by the Lorentz transformation (which Lorentz, about 10 years 
earlier, thought were just a mathematical trick to explain observations).

> Real physics as opposed to that fantasy of Einstein's?

Both are real physics, but it turns out that the older, Galilean 
transformation is only an approximation of what really happens, and what can 
be calculated with the Lorentz transformation, for relative speeds that are 
much less than the speed of light.  This is unsurprising as in the about 
300 years since the Galilean transformation had been devised, measurement 
accurancy had increased, and is still increasing, dramatically.

These are the Lorentz transformation equations for a frame S' that is moving 
at speed v relative to a frame S along an axis (unprimed coordinates are 
measured in S, primed coordinates are measured in S'):

  x = γ (x' + v t)

  t = γ (t' + v∕c² x')

where

  γ = 1∕√(1 − v²∕c²)

These are the Galilean transformation equations for the same case 
(parentheses kept intentionally):

  x =   (x' + v t)

  t =   (t')

It is rather easy to see that as v approaches zero, i.e. becomes small 
compared to the speed of light c, γ approaches 1, and the Lorentz 
transformation equations approach the Galilean transformation equations, and 
are equivalent to them if v = 0 (at relative rest).

From the Lorentz transformation also follows that speeds do not simply add.  
For a relative speed u' = dx'∕dt' of a frame T measured in a frame S' moving 
at speed v = dx∕dt relative to a frame S along an axis, the measured 
relative speed u of T in frame S is

  u(v, u') = (v + u')∕(1 + v u'∕c²).

Again, one can easily see that if v and u' are small compared to the speed 
of light c, the relativistic composition of speeds reduces to the Galilean 
addition of speeds:

    lim    (v + u')∕(1 + v u'∕c²) = v + u'.
  v u' → 0

That is, the addition of speeds is a good approximation for the actual, 
relativistic composition of speeds for speeds that are small compared to the 
speed of light.  One can also see from that why speeds that are faster than 
the speed of light have not been observed: even

  u(v = c, u' = c) = (c + c)∕(1 + c²∕c²) = (2 c)∕2 = c.

And it has been experimentally confirmed numerous times that the Lorentz 
transformation, _not_ the Galilean transformation, is in accordance with 
what is being measured, for *any* relative speeds.

Therefore, to say that special (or general) relativity is “a fantasy” is  
outright ridiculous.  But so say the utterly ignorant – those who do not 
know and do not want to know.  Like you.

Probably because even this simple arithmetic (if the speed of light is the 
same in every reference frame, then clocks in the moving frame cannot be 
observed to be synchronized as one clock is moving *away* from one light 
pulse and one is moving *towards* the other pulse) and geometry (application 
of the Pythagorean theorem shows time dilation) just goes well over their 
head.

Yes, of course.  There is no good reason to assume that the laws of physics
are different in any part of Earth than in another.  In fact, all 
observations so far – and there have been billions, if that is even enough – 
show that they are the *same* *everywhere* in the observable universe.  And, 
more practical, every technology of modern Terran civilization, including 
the computer that you are abusing to insult people, depends on that.

Wrong. You have developed an interally consistenty set of

Physics has been that way since 1839. Magueijo and Smolin, despite
your fondest wishes, have recognised the nonsense (though not yet
its origin). They might even break through the barrier of academic
prejudice and do what I have surmised before: reinstate Physics as
a science.

Wrong again, moron. That you assumed I wasn't questioning your opinion
of it shows (once again!) that it's you who don't know what I'm talking

Wrong, wrong, wrong and wrong (can you guess which "wrong" refers to
what parts of your whine?). I insult you with deliberate intent.`

You have my permission to guess at that. (here's a hint: if you
can't stand the heat, get out of the kitchen.)

Your garbage characters are no more convincxing than your garbage

I told you to look the word up, you moron. None of those postulated
effects has ever been observed. All of your so-called observations
are interpretations, usually based on circular reasoning;, always
based on unjustifiable assumptions and invalid conclusions.

----dogmatic waffle snipped----

And back to the matter at hand: no-one has ever observed length
contraction (in your Einsteinian fabtasy sense).

It has been observed.  That you do not know or do not want to accept that, 
does not change reality.

You are a hopeless case, and I am done wasting my precious time with you.

For those who are willing to learn: I just found a very nice, very simple 
*oral* explanation of time dilation *and* length contraction that just uses 
basic geometry (in particular, the Pythagorean theorem).

Poor idiot. If it was possible to conclude your idiocies
just from basic geometry, they would be theorems of basic 
geometry.
BTW, your idiot guru has rejected Pythagorean theorem,
together with basic geometry.

"Simplistic" is the word you're looking for, Pointy Head.

No it doesn't, you cretinopus bumbling bozo. It also uses that
idiotic assumpyion of invariant light speed.

> <https://www.youtube.com/watch?v=rek7881OGRY>

AND it violates basic relativity (you remember that one, Pointy Head?)

Put a juggler in the truck with the light "clock". Now tell us what
happens to the balls the juggler tosses into the air with the truck
in motion.

From his frame of reference AND from ours, moron. Where's there
ary difference?

Samely, as it was shown that walking a street an observer observes
trees and buildings running around him.
Enchanting the reality, as expected from a brainwashed fanatic.

Excellent obs, Dr. Mlwozniak. Also, your interlocutor is calling it an 
"effect" which is NOT, and can be NOT.

Wrong.

He should have said "moving", not "running".

Either way he mixes two different things and uses the same word to describe both
pretending the are the same. Garbage in, garbage out, as they say.

Nope. In the onserver's frame of reference, the trees and buildings
are mpving around him.

It didn't change. Perhaps you should reread what Woz wrote (but
read " moving" where he wrote "running").
