QuoteSome even declare that there is no paradox even without analyzing the situation from the perspective of traveling twin.That would be correct. There is not paradox no matter how you look at it. It only becomes paradoxical if one drags in biases from outside of relativity theory.

ps - is there any possible way U could avoid using SR/GR & give a Simplistic answer.
I don't recall Maxwell mentioning relativity. He simply proposed a formula for the propagation of an electromagnetic wave.
QuoteQuote from: Origin on Yesterday at 19:19:01If the lights were synchronized at zero m/s, then no matter how fast you were going they would stay synchronized.Not true. Them being synced is a frame dependent thing, and after acceleration, they'd be synced in neither the train frame nor the original frame, although at 0.01c, they'd be really close to being in sync in the original frame.

Do they use general theory of relativity framework? Or they strict to special theory of relativity instead?Do they take Doppler effect into account?
QuoteQuoteIOW the light from both sources would continue to hit you at exactly the same time.Sorry but no. The front one hits you first since you're moving toward it in the frame in which the two blinks are synced.

Or they strict to special theory of relativity instead?Do they take Doppler effect into account?My suggestion is that you type the following into your search bar: "special relativity lectures".After hitting return, you'll get a lot of hits. Try some of the material from universities, they have to teach the "right stuff", 'cause they just do.
Have you watched them yourself?
Can you summarize what they say?
What makes them more trustworthy than the others?
Quote from: alancalverd on 06/01/2024 14:29:22I don't recall Maxwell mentioning relativity. He simply proposed a formula for the propagation of an electromagnetic wave. He thought that light speed is constant relative to aether. That's what motivated MMX in the first place.

I have no idea what he thought.
James Clerk Maxwell's view on the aether was complex and evolved throughout his career. Here's a summary:Early Acceptance (1860s):Initially, Maxwell embraced the aether concept, believing it necessary for explaining light propagation as transverse vibrations. His famous equations for electromagnetism were built upon the aether model.He saw the aether as a stationary, elastic medium permeating all space, capable of transmitting electromagnetic waves without significant energy loss.
If they are accelerated along the axis of propagation, this is equivalent to placing them in a divergent gravitational field,

His onboarding clock ticks slower on average than the giant clocks.Which clock ticks faster is a frame dependent thing, and no frame was specified, so no, this isn't correct.Relative to Earth, the ship clock ticks slower. Relative to some inertial frame in which the ship is stationary, the Earth clock and all the giant clocks tick slower. QuoteTraveling twin sees the giant clock the he is passing by showing the time according to Origin's calculation. Earth clock ~ 4Second clock ~ 5Third clock ~ 6Fourth clock ~ 7Star clock ~ 8, then return. Fourth clock ~ 9Third clock ~ 10Second clock ~ 11Earth clock ~ 12Yes. This is consistent with the numbers in my prior post.For instance, from the ship PoV, at the start, the 2nd clock appears to read 3 (just like you said in post 36). 16.3 days later when the 2nd clock passes by, it reads 5, which means it appears to run ~45x as fast because it is approaching, exactly the rate that I posted.Let's pair the values of the giant clocks with travelling clock.Earth clock ~ 4Y --- 0 dSecond clock ~ 5Y --- 16.3 dThird clock ~ 6Y --- 32.6 dFourth clock ~ 7Y --- 49 dStar clock ~ 8Y --- 65.3 d, then return. Fourth clock ~ 9Y --- 81.6 dThird clock ~ 10Y --- 97.9 dSecond clock ~ 11Y --- 114.2 dEarth clock ~ 12Y --- 130.6 dObservers on giant clocks and travelling clock should agree with these values.

Because Craft is moving Forward...Front blinking light has to cover less distance/space.Back blinking light has to cover more distance/space.
