Default Speed gedanken time (repaired) time dilation 099

(repaired version thanks to OG)
Lets suppose we have a flat surface that is
as far as we know infinite in length and width.

We mark a line and call it the 0 point.
we then mark lines that are 1 mile away from
this 0 point so we will have parallel lines every 1 mile.

An observer stays at the 0 point (A)
a second observer is in a spaceship (B)
traveling at at .5c and the clock that is
at the 0 point(A) starts when it (B) passes the 0 point.
According to basic math and the clock at observer (A)
position, the object will pass by the 93,000th line in 1 second.
and the 186,000th line in 2 seconds
etc...
(silly basic math)

so...

( I think it is all stated correctly this time..)
How many lines would (B) pass if using time dilation
as a physical fact for (B) according to SR.

in 1 second - it would pass 93000 lines - however the observer in (B)
wouldn't agree that the lines are 1 mile apart.

(they are physically 1 mile apart)
Please explain why observer (B) would not say such?
What physical evidence would (B) have to prove they are not?

Special relativity, space****. You think you know special relativity
then this comes as a surprise?

What physical evidence would (B) have to prove they are not?

Eric,
apparently you think you are so smart,
yet you have no clue, you are actually backing up
one of the biggest scientific walls in the history of science.
It is pretty funny to me, yet it is very sad for you..
LOL

In 5 years you will be in the same place you are now. That is funny to
me.

Is that an SR prediction?

Too bad you are the one that will still be stuck in the
spacetime box with no way out..

You need to ask HOW observer (B) would measure the separation between the
lines. Think of this as a real practical problem. How would YOU do it?

When you have thought of a method, you then need to remember that sucessive
lines will be moving relative to the observer (B) with a speed of .5c - this
inevitably affects the measurement of the separation between the lines.

You stated " however the observer in (B)
wouldn't agree that the lines are 1 mile apart."

I did not make that statement, you did.
so...
It is you that should give a reason for such.

If I were trying to "physically measure" something like such
I would turn around and stop the ship and physically measure
it in reality, so I would not have any problems
with the measurement being a "non physical" abstraction instead
that could be wrong compared to the physical reality of the
physical measurement.


I want to hear "your version" of why observer (B)
would not agree to the lines being 1 mile apart
since you stated such.

What makes you think that observer (B) would measure the same as observer
(A). He's not in the same coordinate frame at all is he?

If I were trying to "physically measure" something like such
I would turn around and stop the ship and physically measure
it in reality, so I would not have any problems
with the measurement being a "non physical" abstraction instead
that could be wrong compared to the physical reality of the
physical measurement.


Ah, but your measurement would not be made by observer (B), would it? After
all, while you have stopped, gone back and measured the separation between
two successive lines, maybe double checked them etc etc, observer (B) has
whistled off into the distance at a speed of .5c. Not the same thing at all
is it? Again, by stopping to measure the distances, you are removing (B)'s
involvement in the measurement.

I want to hear "your version" of why observer (B)
would not agree to the lines being 1 mile apart
since you stated such.

Of course,
The reason that (B) does not agree is because when you have one coordinate
frame moving relative to another, distance measurements made in one frame
are contracted relative to the measurements made in the other.

Since distance measurements in ANY coordinate frame depends on information
travelling between successive lines, the speed of light is an important
factor.

When you have two coordinate frames moving relative to each other, the ratio
of relative speed:light speed is important.
