According to this article, it's not a violation. http://www.eurekalert.org/pub_releases/2007-08/ns-lst081607.php[^] There are plenty of waves that travel faster then the speed of light, however their group velocity[^] can't exceed the speed of light, which is the speed that information is transmitted for most waves.

A pair of German physicists claim to have broken the speed of light
The key word here is 'claim' I think. Not that I don't think we could not do this. When you get down to quantum level all sorts of odd things happen. I personally just question how they were able to even measure this to a degree of precision that they can claim the 'instantaneously' part. Even a clock tick takes some time. Yeah, I know you can zero balance the clocks and account for the time it takes for the time to be registered and then do some subtraction and... ...but, correct me if I am wrong here, for this to be REALLY faster than light travel the time form point a to point b needs to be negative right? Even if it is instantaneous all you have proven is that you can travel 'as fast as light' not faster. Do not think I am in any way discounting this either. I love to see people stretching science this way. I just think that the media jumps on stuff a bit fast. Remember cold fusion?

Ahhhhh ok, so it seems that it may be a bit of mis-interpretation on the scientists part.

Based on a quick scan, this doesn't seem all that different in concept to EPR & The Aspect Experiment. Plus what Andy said.....

Light does not by any means travel instantaneously. How do you think we get the term light year[^]?

Damn it! I hope this is more real than its criticisms have so far implied. I hate the fact that we can't exceed the speed of light. In a universe as big as it is it's crippling to be effectively infinitely away from every thing no in our solar system. We're absolutely stuck here even getting to the moon is a complete pain in the arse. If there really is no way of jumping these grossly enormous distances we simply have the inevitable death of our species looming before us. I know the timescales I'm talking about are enormous, I just don't like them being there. And there's so much for some reason I'd love to see, like super massive black holes and our galaxy from the outside. Fuck all use but still if none of us ever will it's real spoiler.

Check out New Horizons[^]. It's the fastest spacecraft ever launched, traveling at 16.21 km/s. Lots of hope there for the future of exploration if the politicians can ever get their heads out of their asses and re-realize the benefit that scientific discover has brought to us.

Awesome, I'd start by reading about The Photoelectric Effect[^]. Skipping past Maxwell, who if he hadn't died early was well on track to make this discovery well before Einstein, this is what really this ball rolling.

That's still a very long way off 299,792,458 m/s :sigh: We need something that can completely bypass this whole speed/mass issue. Another annoying thing about this discovery is that I found this little bit of info from Wikipedia
Wikipedia quote:
It has long been known theoretically that it is possible for the "group velocity" of light to exceed c.[6] One recent experiment made the group velocity of laser beams travel for extremely short distances through caesium atoms at 300 times c. In 2002, at the Université de Moncton, physicist Alain Haché made history by sending pulses at a group velocity of three times light speed over a long distance for the first time, transmitted through a 120-metre cable made from a coaxial photonic crystal.[7] However, it is not possible to use this technique to transfer information faster than c: the velocity of information transfer depends on the front velocity (the speed at which the first rise of a pulse above zero moves forward) and the product of the group velocity and the front velocity is equal to the square of the normal speed of light in the material.

"The object of life is not to be on the side of the majority, but to escape finding oneself in the ranks of the insane." - Marcus AureliusYeah, I think the speed of light is a poor name for the phenomena. It is really a "speed" of space and is a consequence of the geometry of space-time. It just happens that light travels at that speed because it is a zero rest mass particle.

I think that once we start running out out of minerals like Titanium on Earth, and private corporations realize that there is a virtually infinate amout of them on the Moon and in the asteroid belt, that is when we will start seeing some major advances in space travel.

actually I think this is something different. the group velocity refers to the location of a superposition peak of a series of waves traveling at different speeds, it's not a quantum effect which is what this article is apparently talking about.

at a fundamental level QM and GR are both absolutely totally correct in every way we can test. They're also mutually incompatible, ultimately finding something that is an absolute violation of one or the other is key to actually being able to sort among the menagerie of unified theories that encompass both of them.
