Dale replied to the thread B What reference frame is used for the velocity v in the Lorentz transformation?.After a very brief discussion among the mentors, we will leave this thread closed. As @weirdoguy mentioned, we have shown how the math... -

Like.
Official standard: WCAG (Web Content Accessibilty Guidelines) published by the World Wide Web Consortium (W3C), widely recognized... -
Dale reacted to weirdoguy's post in the thread B What reference frame is used for the velocity v in the Lorentz transformation? with Like.
And people pointed MULTIPLE TIMES how to resolve your problem. You did nothing with that. In the end, experiments falsify your point of...

Dale reacted to Ibix's post in the thread B What reference frame is used for the velocity v in the Lorentz transformation? with Like.
Every single one of us answering your questions has thought about it. We were all where you are once, but we studied and learned how the...

Yes, because that's how reality/universe works. It's you that have problem with reality, because it does not work the way you want it to.

Dale replied to the thread B What reference frame is used for the velocity v in the Lorentz transformation?.Yes, I have, and they do not matter in the end. They are the standard questions that most students ask as distractions from the actual...

Dale replied to the thread B What reference frame is used for the velocity v in the Lorentz transformation?.It doesn't matter what you or he thinks about reality. What matters is what actually happens in reality. This is confirmed by...

Dale replied to the thread I How do non-diagonal indices of a metric allow for local flatness?.It means that at any event in spacetime there exists a set of coordinates where the Christoffel symbols all vanish as do their first...

Dale replied to the thread Site Usability nitpick -- Hyperlinks should be underlined.But do we have any actual evidence that underlining links promotes accessibility? I support the goal, but I am not convinced that this...

It seems that you're not here to learn, but to argue. Telling physiscists that they haven't realized the complexity of issue when you...

Dale replied to the thread B What reference frame is used for the velocity v in the Lorentz transformation?.Indeed. That requires experiments. The calculated results are consistent with a large amount of experimental data. In particular...

I can do this easily (except for the bits you haven't specified l, discussed below). The point is for you to familiarise yourself with...

Dale replied to the thread B What reference frame is used for the velocity v in the Lorentz transformation?.Yes. ##2020-2015## is ##5## years and ##2025-2015## is ##10## years. So the mathematical question is, do there exist two timelike...
