In some cases this can exceed c, but as the article says, this does not transfer matter, energy or information. [link to en.wikipedia.org] You can do something conceptually similar using a (very powerful) laser pointer. Just point it at the moon, and then move it around. A tiny movement of the pointer produces a huge movement of the illuninated spot on the moon, and it's not at all hard to make that illuminated spot move around far faster than light. |

Quoting: Anonymous Coward 710109Those phones would have more reliable service and would also be more difficult for hackers to intercept, Singleton said.

Well i kind of knew already it was bogus,but I'm just a nobody and nobody would listen to me,i guess good for the scientists that demonstrated) So much for him being a genius. |

Anonymous Coward User ID: 660262 Netherlands 06/30/2009 05:10 PM Report Abusive Post Report Copyright Violation | One of the comments from the Santa Fe New Mexican article linked to the actual scientific paper. [link to arxiv.org] I'm going to go and read this now to find out what he was _actually_ doing. The abstract talks about superluminal currents surrounding pulsars; this is plausible. Go back to the idea of tracking a laser pointer across the Moon: well, a pulsar spins thousands of times a second, so any beam projected slower than light outward from its surface could easily track across surrounding material faster than light. Apparently the interesting discovery isn't that superluminal effects can be produced; that's trivial and non-interesting. It's that they can be used to produce extremely coherent beams. That bit about them dropping off as 1/R rather than 1/R**2... well, if that can be replicated technologically, it's great news. It will save a _lot_ of power on long-range communications. |
Anonymous Coward User ID: 1978 Canada 06/30/2009 05:18 PM Report Abusive Post Report Copyright Violation | this is nothing new, the former Iron butterfly bassist invented a communication technology that uses gravitational waves and was dissappeared for it. The rumor was that he was in contact with extra-terrestrial civilizations that the NWO doesn't want us talking to. Quoting: Anonymous Coward 460855hole crap, I'd never heard that before . |

Anonymous Coward User ID: 660262 Netherlands 06/30/2009 05:24 PM Report Abusive Post Report Copyright Violation | ... ah, OK, that makes sense. What's going on here, guys, is not about sending signals faster than light in any way. Quick lesson in electromagnetism: a radio signal is generated by an alternating electric current. You run the current up and down an antenna at a particular frequency, you get an induced electromagnetic field that spreads out from the antenna. That's your transmitter. Set up another antenna at a distance attached to a circuit tuned to the same frequency, the field induces a current in that circuit, and you've got a receiver. Simple, right? Now, what happens if that current moves through the antenna faster than light? Can't be done, you say? Nothing moves faster than light? Well now. What if we could beam electrons into the conductor from a distant location, and just change the aim regularly? No actual electron would ever move faster than light - but if we got the timing right, we could make the _point of impact_ of the beam move faster than light, and that would look like a current flowing up and down the beam. As it turns out, the result of this is just as if there really was a superluminal current. They've worked out what should happen, which involves some rather obscure and technical detail resulting in some quite unusual radio beams, and shown that it's consistent with what happens in some pulsars (which spin fast, and therefore can produce apparent superluminal effects of this kind). And they comment in the press (though they do not say so in the article) that such beams might be useful in very long distance communications, since they drop off linearly with distance rather than as the square. In other words, if you're twice as far away it takes twice as much power to achieve the same signal strength; normally it would take four times. |
