Like.
I'm not asking what it shows, I am asking what the thing it measures is. I am trying to get you to reconcile your statement that "space... -
Dale replied to the thread High School Einstein equations don't work at large scale?.We have clocks that are sufficiently precise to measure relativistic effects at human speeds (jogging or biking). So the issue is the...

Dale reacted to Sagittarius A-Star's post in the thread High School I don't understand the Michelson–Morley experiment with Like.
Are you sure the quoted text is from Einstein? In which paper did Einstein write this?

So you are assuming your "nothing" obeys Euclidean geometry. Why?
-
Dale replied to the thread High School I don't understand the Michelson–Morley experiment.Space can be measured. So if space is “nothing” then “nothing” can be measured. And if “nothing” can be measured then why couldn’t those...

Dale replied to the thread High School Einstein equations don't work at large scale?.I mean accurate to within the experimental precision.

Sort of. There were a lot of patches to electromagnetic theory that amounted to SR, but they had not been recognised as such. Poincaré...

Note that this is very much a modern retrospective view of it. The actual history is somewhat more tangled, and I very much doubt Newton...
-
Dale replied to the thread High School Einstein equations don't work at large scale?.The only way to know that a theory is wrong is to obtain measurements that contradict it. Those are reasons why Newtonian physics...
-
Dale replied to the thread High School Einstein equations don't work at large scale?.Yes, and we also have lots of evidence validating Newton’s laws. We can’t wish that away either. The existence of that evidence is why...

Of course. We have observational and experimental evidence (a lot of it!) of Newton's laws being violated, some of it pre-dating the...
-
Dale replied to the thread High School Einstein equations don't work at large scale?.Because we have found experimentally that it does work at scales like 4 m and 50 km/h to 200 km/h. If we eventually find that it doesn’t...

Not being curved but flat is also a geometrical property. Why is it OK to assume that 'nothing' is specifically flat.

Then what does a ruler measure?

No it isn't a better word. Logic by itself just excludes self-inconsistent theories, but doesn't tell anything about whether time should...
