@ Neox, that isn't the arrival problem I'm talking about.

Hello,
As it takes time and attention to a problem before papers are produced, it is certainly plausible that a feasible refutation exists that has not been identified and produced in the literature. That refutation need not necessarily be an alternative version of general relativity; it could...
Upon reading the Australian paper, I've noticed that they only use the bubble configuration initially proposed by Alcubierre, which as I understand requires far too much energy to be possible to implement. The later bubble configuration proposed by White, which is instead a ring, apparently is...
Ok, there is ambiguity in this area.
A wikipedia article on Van der Walls suggests that each originate from vacuum energy:
"It can be shown that van der Waals forces are of the same origin as the Casimir effect, arising from quantum interactions with the zero-point field.[2]"
From...
I'm interested in developments concerning the 'Alcubierre Warp Drive', specifically, the arrival problem:

Well, you cannot patent an idea, you must patent a process. So, you've not yet created a public disclosure, if you were to reveal a particular method or process, hypothetical or otherwise, that would constitute a public disclosure. To create a process to do something, you will need to do it...
The wikipedia page had a formula for finding the force between two plates as a function of distance, but not one for energy density. Rather than trying to derive it myself I was hoping someone more experienced with it could provide a correct formula for this. Demystifier, this sounds like it...
Look, there are other effects of vacuum fluctuations, not just the Casimir Effect. Hawking radiation for example. It isn't a very contentious issue in the field. It's basically accepted. I'm not really interested in arguing. If you don't want to believe in vacuum fluctuations, fine. I'm just...
I was aware of the paper that I referred you to before the conversation, but I was not aware of the paper you referred me to. But as far as I know, it's been pretty well established that the Casimir force is due to vacuum fluctuations. I'm not sure how the Croatian physicist came to his...
That paper is definitely a minority opinion. Also, I believe that it is disproven due to the fact that the casimir effect can be reversed:

If the Casimir force was caused by van der walls forces, I do not believe it would be...
Hello,
I would like to know how to calculate the negative energy density in the region between two Casimir plates, given a distance between two parallel plates.
Thanks, much appreciated!
I asked Dr. Philbin at the University of St. Andrews about the reverse Casimir effect. He gave an excellent description:
"
One of the problems with trying to have a conceptual understanding of
Casimir forces is that the calculations using the standard Lifgarbagez
theory (which predicts...
