bump.
Come on, guys. The Elitzur-Vaidman bomb tester is the most startling experiment of the last 20 years, and yet there are less than a dozen posts here that mention it (and none that focus on it specifically.)
It essentially letting us peek into Schrodinger's box. It allows us to...
That works as long as you're dealing with intangible microscopic particles, but at some point the cat (Schroedinger's) is going to get out of the box. What then?
I hate to shamelessly advertise my own thread here, but the Elitzur-Vaidman bomb tester is one such example of the cat getting out...

Assuming I understand this right, we've been able to test counterfactual events (i.e. interactionless measurement) for fourteen years now. Not as a thought experiment, but as an actual functional machine. Why the hell isn't anyone doing...
Is there any particular source you can say it contradicts? Not to be picky, but if this really is an urban myth (and apparently a *reasonably* widespread one), I would like to thoroughly debunk it on Wikipedia.
A variation of the double-slit experiment--myth or did somone really do it?
I've heard this experiment described at least three times; possibly more. However, none of the sources are terribly reliable--Scott
Adams in the last chapter of The Dilbert Future (and he freely admits that he gets a...
60 hour work weeks suck.
I disagree. It's an interesting subject to discuss and debate.
But yes, my original purpose is satisfied. Despite your not-entirely-coherent objections (no offense intended), the consensus seems to be that IF exotic matter exists, it should induce negative time...
Sorry I was gone for a while. I caught the flu pretty bad...
My point was that there is also a lower limit on vacuum energy as dictated by Uncertainty. This is the key to my assertion, and if I'm wrong on this point then "less energy than the surrounding space, but still positive energy" is...
JesseM:
(ok, sexy girlfriend can wait 5 minutes damnit)
The central point I'm trying to make it that vacuum energy is necessary to preserve Uncertainty. If energy is decreased, then we may be too certain about the energy/mass value of virtual particles (I'm not sure which other value...
RandallB:
1. I don't care about wormholes at all. They may or may not exist, but they have no place in my ideas or assertions. Neither does backwards time travel.
2. I aim to be writing more of a "hard" sci fi story than pop sci fi.
3. I don't care if Casimir doesn't prove QM. I wasn't...
Eh, I really don't see how this addresses any of my statements one way or the other. Do you agree with what I have read and asserted, that the Uncertainty principle regarding energy (wikipedia implies that is it energy vs. position, though I suppose it could be energy vs. time) says that we...
I don't want anyone to get the impression that I'm pulling stuff out of my ass, so:
Mainstream physicists have said that the Casimir Effect arises as a consequence of Uncertainty, not that it violates it. Mainstream physicists have also brought up the possibility of negative energy or...
(emphasis mine.)
This means that empty space cannot exist, because empty space=0 energy. This is why we have "quantum foam" or zero-point fluctuations instead. And the Casimir Effect is a direct test of the existence these fluctuations. That is the relationship between the Casimir Effect and...
I do not know where I first read about the connection of the Casimir Force to the Uncertainty Principle, but a quick wikipedia lookup yields:
So it appears as though empty space in QM is subject to the same Uncertainty limitations as particles.
This is exactly my point. Creation of...
Negative energy is related to conservation of energy because mathematically, one should be able to create energy out of nothing if one also creates an equal amount of negative energy.
My point, which you may or may not have refuted (unfortunately I have very little formal education, so many...
