Dale replied to the thread High School Einstein equations don't work at large scale?.No. Intuition is the correct word. It is true that most people find relativity unintuitive. It is false that it is illogical. No. It is... -

If you define "time" like Einstein did (Time is what a clock measures), then it was experimentally verrified, that time is not absolute...

I find the disciption of space-time in relativity more intuitive and easier to understand than that of non-relativistic physics.

Isaac Asimov's essay The Relativity of Wrong is worth a read. George Box put it rather more pithily as "All models are wrong. Some are...

Dale replied to the thread High School Einstein equations don't work at large scale?.I don’t think there is an answer that is both simple and complete. Newton’s laws have been experimentally shown to be correct in the...

Dale replied to the thread High School I don't understand the Michelson–Morley experiment.There is 1 astronomical unit of space between the sun and the earth. You can use the word “nothing” to refer to space if you like...

Probably. And some scientists do argue that dark matter and dark energy are evidence of failures of GR (MOND theories attempt to explain...

Light always travels at ##c## in vacuum. How would you tell the difference between a theory that fits reality and a theory that only...

Not if we are standing on the back of a flatbed truck so that the air is moving past us at 100 km/hr. The wind changes the speed of the...

Correct circulation theory does give correct lift values. But correct circulation theory does not claim that air goes around the wing in...

Dale replied to the thread High School I don't understand the Michelson–Morley experiment.That is a measurement. Because it leads back to this false claim: Your claim is false. The only reason that you know the circulation...

...and there you go citing measurements and observations to try to prove that just measuring and observing isn't enough.

Dale replied to the thread High School I don't understand the Michelson–Morley experiment.So how do you know that it is wrong? How do you know that airflow doesn’t travel around the wing in a circle?
