There are 2 ships that are passing each other at high speed.

No, it's your insistence that simultaneity is absolute that is invalid. You are like the flat Earther who insists the the Earth can't be a globe because the people in Australia would be upside down.

In all your years of struggling with relativity, have you never read about this?: https://en.wikipedia.org/wiki/Relativity_of_simultaneity

If not, it’s high time you did.

Although theorized and hinted at, RoS, as far as I know, has never been directly observed. as have time dilation and length contraction.

Wrong. Very easy to demonstrate and have been for 120 years.

You need to look at the experiments with atomic clocks, atmospheric and particle accelerator decays.

When T1 turns on his lamp, T2's lamp is simultaneously both on and off which is impossible. Therefore special relativity is invalid.

Not at all. It's just that you don't understand it.

Here's a much simpler scenario -

Person 1 is one light second away from person 2. (About 200,000 miles away; say on the Moon.) Person 1 turns on a laser aimed at person 2. After half a second, person 1 sees that the laser is on, but person 2 sees that it is off!

Does that violate any physical laws?

Has nothing to do with proving RoS, only time dilation.

And length contraction, seeing as it's the other side of the same coin.

 

[Wizard of Whatever]

In 120 years only TD and LC have been objectively proven.

No, proven by flattening of particles at near c.

 

[Pinball1970]

These only directly prove time dilation not RoS.

Einstein's thought experiments you can do in your head. Lightning strikes? Guy on the train? Guy on the platform?

 

[Pinball1970]

No, proven by flattening of particles at near c.

Eh?

Thought experiments don't prove anything.

 

[Pinball1970]

Thought experiments don't prove anything.

Write it out then. Observer A on train approaching observer B will not see two lightening strikes the same way a stationary observer will see them if he is at the mid point, how could he? He is speeding towards one and away from another.
Guy in the middle receives the light together because the distance is the same from both strikes.

Its still hasn't been proven experimentally.

 

[Wizard of Whatever]

Eh?

Actually shown by flattening of EM fields, too.

Yes it has.

Read up on atmopsheric muon decay at your leisure.

 

[exchemist]

I think he’s making a distinction between time dilation, which we all seem to agree has been shown, by muon decay for instance, and relativity of simultaneity specifically. I don’t think muon decay illustrates the latter specifically, does it? It does not seem to be mentioned in your link.

Which lead to RoS unless you are willing to accept physical contradictions.

Doesn't lead to, only points to possibility. Not yet proven.
