Well, scientists studying relativity seem to have about a million ways
to adjust results to get whatever answer they are trying to get. With
regard to time, I have to say they have been flim-flamming the public
since Einstein gave them a way to do it in 1905.
You probably claim there have been great advances in science. I
don't really see it. To start their present flim-flam, they got
millions of dollars from the U.S government to construct a bomb during
World War II, which they ran up to 2 billion dollars by the end of the
war. For that kind of money, they were happy to take one kind of
radioactive substance, put it into a cannon and shoot it into another
kind of radioactive substance. Scientists all over the world had
speculated that this could be done even before the war started.
So by doing this, they created the greatest man made explosion
witnessed up to that time, and it was all done by believing in a
length contraction. So that proves to scientists that there is a
length contraction, especially when they can get trillions of more
dollars from governments by saying there is a length contraction.
Scientists of today cannot explain the length contraction, but
their faith in it is absolute because it is the source of all good
things, (money), in their lives.
All I have to do to provoke an outcry is to post in sci.physics
relativity that there is no length contraction, and scientists will
start screaming, Blasphemy, blasphemy.
Now here is something interesting. The Galilean transformation
equations do not show a length contraction.

No .. they'll just tell you that your logic is wrong. What you claim to be
the case is refuted by experimental evidence. It is simply wrong

More to the point, they do NOT show time dilation .. and we observe that
happening. So they are wrong.

You are flogging a dead horse. . and have been for years

Well, I do not flog horses. I don't need to. Generally, I walk
wherever I go. One thing is obvious to me, scientists are
perpetrating a flim-flam. So I give them an example, easy to
understand, marks every ten meters on S and marks every ten meters on
S', and they pretend they do not understand how that could be. Well,
OK, show the mathematics that you do not understand.
t'=t. You have failed to show any proof whatsoever that this equation
applies to anything other than the marks on S and S'. It means that
the marks on S are the same distance apart as the marks on S'. When
S' moves relative to S, the marks line up with each other the entire
lengths of S and S' every time the moving frame of reference moves 10
m. This is true when S' is moving at 1 m. /yr. and it is true when S'
is moving at .99999c. You have no mathematics that shows otherwise
because you have a time dilation that shows too much time on a clock
in S', and consequently you have to compensate by saying there is a
length contraction. Sorry, t'=t means there is no length
contraction. All you have is a slow clock in S'.
