Jaime Rudas replied to the thread Undergrad Does the Alcubierre drive shorten distances?.I agree -
Jaime Rudas replied to the thread Undergrad Does the Alcubierre drive shorten distances?.Yes, that's the case I was referring to. -
Jaime Rudas replied to the thread Undergrad Does the Alcubierre drive shorten distances?.What I meant is that time inside the bubble flows at the same rate as outside (and far away from) the bubble. -
Jaime Rudas replied to the thread Undergrad Does the Alcubierre drive shorten distances?.I don't understand what you mean, nor do I see how it relates to what I posted. -
Jaime Rudas replied to the thread Undergrad Does the Alcubierre drive shorten distances?.Yes, it seems we're having problems with the issue of relative simultaneity. -
Jaime Rudas replied to the thread Undergrad Does the Alcubierre drive shorten distances?.It doesn't seem weird to me because spacetime at the center of the bubble is flat. The extremely curved spacetime is that of the "walls"... -
Jaime Rudas replied to the thread Undergrad Does the Alcubierre drive shorten distances?.It seems to me that this applies to distances inside the bubble, but not to distances along a path going through the bubble. -
Jaime Rudas replied to the thread Undergrad Does the Alcubierre drive shorten distances?.I agree. I'm not entirely clear on the relationship of this to what I mentioned about peculiar velocity, but it seems to me that the... -
Jaime Rudas replied to the thread Undergrad Does the Alcubierre drive shorten distances?.Taking this into account, could you indicate the calculation to support your claim that the distance between Earth and Alpha Centauri... -
Jaime Rudas replied to the thread Undergrad Does the Alcubierre drive shorten distances?.I think you're the one who should answer that, since you were the one who stated that the distance between Earth and Alpha Centauri... -
Jaime Rudas replied to the thread Undergrad Does the Alcubierre drive shorten distances?.Yes, it's true, I made a mistake when I said I was referring to the length of the path traveled, when what I had in mind was the... -
Jaime Rudas replied to the thread Undergrad Does the Alcubierre drive shorten distances?.Yes, that's right. That's precisely what I said in post #4. -
Jaime Rudas replied to the thread Undergrad Does the Alcubierre drive shorten distances?.##D=\int_{t=0}^{13.8} v_{pec} dt = \int_{t=0}^{13.8} c dt= 13.8 Gly## -
Jaime Rudas replied to the thread Undergrad Does the Alcubierre drive shorten distances?.Davis & Lineweaver present their equations 19 and 20 as follows: As I see it, the velocity I defined is nothing other than what D&L... -
Jaime Rudas replied to the thread Undergrad Does the Alcubierre drive shorten distances?.Locally (that is, at each point), in an expanding universe, the speed of light is c. If I integrate it with respect to time, I get the...
