Dale replied to the thread High School I don't understand the Michelson–Morley experiment.How do you know that a theory is physically incorrect? Are there? If so, please identify one and explain how we know that it is... -
Dale replied to the thread High School I don't understand the Michelson–Morley experiment.How can we check if a theory fits reality besides measurement results?

Like.
Tesla didn't accept that the Moon rotated on its axis either. While he contributed greatly to our understanding of electromagnetics... -
Dale replied to the thread High School Einstein equations don't work at large scale?.This is a very important point in understanding how science actually works. Popper popularized the idea of falsification, but...

Informative.
Back in 1780, it was discovered that Newtonian gravity did not correctly predict the positions of the outer planets. Herschel proposed a... -

Not "wrong", no. It is a valid approximation to GR in the regime where gravity is weak and all relative speeds are small compared to the...

More precisely, if we just use the matter we can actually see as the source in the Einstein Field Equation, the model does not match the...

Dale replied to the thread High School Einstein equations don't work at large scale?.The interesting thing about intuition is that it is not fixed. Intuition is built on experience. At this point I have enough experience...

The frame that sees the Cosmic Microwave Background as uniform. This is the nearest thing to "on average at rest with respect to matter...

Dale replied to the thread High School Einstein equations don't work at large scale?.That is certainly a possibility. It is under investigation. However, even if it turns out to be true, relativity and spacetime...

I see we said much the same things!

Dale replied to the thread High School Einstein equations don't work at large scale?.And indeed this is the current situation. We are currently working along both paths.

Dale replied to the thread High School I don't understand the Michelson–Morley experiment.Probably it is best to not hijack your own thread. You already have another thread in this topic...

Dale replied to the thread High School I don't understand the Michelson–Morley experiment.This is not necessarily true. It is true in ballistic theories of light. It is false in aether theories of light. At the time of the MMX...
