There is a next phys frame:
And the enhancement:
"The aether's true time
" - I see the aether's still strong.
"Everything which moves gets contracted" - moving relative to the aether or relative to you?
Lorentz on in this frame seems to suggest the first,
while the hidden Einstein the second option.
So we reached Lorentz contraction.
Important thing to realise here:
Even if moving objects relative to you
will from your frame of reference
be contracted according to Lorenz contraction,
it doesn't mean you will see
it as contracted this way:
Because you don't see the actual object,
only the light coming to you from the (moving and contracted) object.
Something is moving towards you very closely to the speed of light.
In this situation,
the light from the end of the object
needs to travel for a long distance and long time before it reaches the front of the object.
So when you see it,
the light that reached you from the end of the object is from a much earlier time (when the object was much more far away from you) than the light that reached you from the front of the object.
So even though from your frame of reference the object is contracted it will appear actually elongated!
Similarly, moving away from you it will appear even more contracted than it is.
And moving sideways / diagonally gives an even more interesting result:https://en.wikipedia.org/wiki/Terrell_rotation
(That wikipedia page has some interesting links, like this one, for example: https://www.spacetimetravel.org/

We can actually make it into a physics excerise:
At 25.03.2013, 04:00 UTC a space ship leaves Earth and moves away from it with a constant speed.
At launch time the ship's clock was synchronised with Earth.
The ship is sending is sending messages to Earth each hour (initially also at half hour but that's not relevant) according to its internal clock.
The messages travel to Earth at light speed.
On Earth, the time delay between the messages is slightly longer than a hour,
so that the message for 14.08.2019, 17:00 was late by 0.134h.
What is the speed of the space ship and how far away from Earth is it now?
(The ime difference is a result of 2 things: time dillation, and time to reach the Earth at light speed)
Also is it a coincidence that the server name is c
ETA: I was reminded of something.
I was in Germany a few months ago.
You nkow the saying that all roads lead to Rome?
Apparently, in Germany all roads lead to Ausfahrt.
We were going on a highway,
and on each exit there was a road sign to Ausfahrt...
Edited to fix date 14.8.2019, not 17.8.2019, I confused the hour with the day.
Tdited to fix mistake in name.
