Somehow the SR people seem to doubt the validity of earth at rest in
origo using a cartesian coodinate system.

They seem to doubt that Tycho Brahe actually plotted the not only the
planets orbits around earth but also the suns, using the earth as a
center in a cartesian coordinate system.

They seem to doubt that simultanity will exist in the defined rest
space of Euclidian space.
I can easily give PROOF for that simultanity exist in Euclidian space
and in a Cartesian coordinate system.

So why don't you people make a Euclidian space event diagram as i
proposed and everyone can judge for themself if light travels
invariant or variant through space?

And why satisfy with plotting the expanding wavefronts in just x-axis
and y-axis direction why not send pulses along all the 360 degrees and
make a nice sphere at moment t1.

PS do not forget to plot in ship B-behind and F-front i think is a bit
curious about the enclosure speeds.

Do not anyone of you got the balls?

Nice answer but no goldstar i do not see the diagram.....
It can not be that hard you write those nonsense spacetime diagrams
all day but you have a fucking hard time plotting curled space haven't
you heheheh lol

Well Sue, Dirk, Robert, anyone who will be the first to plot the
wavefronts at moment t1=1 sek t2=2 sek using planet origos restspace.
Ship B fly 30 km behind ship A and ship F 30 km in front of ship A.
Ships are 30 km long.

All flying positive direction along the x-axis in 0.9999 c when A pass
origo two lightpulses are sent along the x-axis in positive and
negative axis.

Your mission is to plot the wavefronts in a diagram at moment t1 and
t2.

Find out respective wavefronts enclosure velocity to respective B and
F.

Find out how long it take for each wavefront to pass from front to end
at B respective F using the euclidian time of planet origo.

For extra stars plot how the lightpulses expansion look like if sent
along more angles to plot a nice expanding sphere.

can wait another 8 but infinity is not an option.....)

This is not spacetime...
