Like.
Yes, I agree with you. -
Jaime Rudas replied to the thread Undergrad Does the Alcubierre drive shorten distances?.Regarding the D&L paper, I think there might be an error in footnote 11 on page 19. Shouldn't it be ##v_{rec}(t_{em}) =\dot...

Agreed. I would say that how the proponents describe it is a very significant contribution to how the community perceives it.
-
Jaime Rudas replied to the thread Undergrad Are Alternative Dark Energy Models Treated More Favorably Than MOND?.I think it's more about how the scientific community perceives it. In other words, the question in the OP is whether or not the...
-
Jaime Rudas replied to the thread Undergrad Are Alternative Dark Energy Models Treated More Favorably Than MOND?.Yes, what I wanted to emphasize is that the level of skepticism is more related to whether or not the model deviates from General...

IIRC, Vanadium 50 used to comment that MOND (or at least some variations thereof) works almost embarrassingly well at the scale of...

Jaime Rudas replied to the thread Undergrad Are Alternative Dark Energy Models Treated More Favorably Than MOND?.I think the issue has to do with the fact that General Relativity is one of the most successful theories in history, so any model that...

Informative.
The best rule of thumb is to think of an experiment whose actual measured outcome depends on the thing in question. -

The speed of expansion of the length of an elastic band certainly does. You could measure the stress or the strain in the band.
-
Jaime Rudas replied to the thread Undergrad Does the Alcubierre drive shorten distances?.For example, if I have an elastic band that is one centimeter long and I stretch it for one hundredth of a second, its final length will...
-
Jaime Rudas replied to the thread Undergrad Does the Alcubierre drive shorten distances?.I don't know how to determine whether something has physical meaning or not. For example, I can't understand why the speed at which an...

Jaime Rudas replied to the thread Undergrad Does the Alcubierre drive shorten distances?.Once again: I made a mistake
-
Jaime Rudas replied to the thread Undergrad Does the Alcubierre drive shorten distances?.Once again: I made a mistake when I said I was referring to the distance traveled by the photon.
-
Jaime Rudas replied to the thread Undergrad Does the Alcubierre drive shorten distances?.As I understand it, the peculiar speed is relative to a comoving observer, that is, with respect to an observer whose peculiar speed is...

Jaime Rudas replied to the thread Undergrad Does the Alcubierre drive shorten distances?.The fact that the peculiar speed of light is c is something I took from Davis & Lineweaver, and my knowledge of the subject isn't...
