'We have broken speed of light' [modified]

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. Come on scientists, break this crappy law Tom

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.

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.
This blanket smells like ham
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.

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

Tunneling is entirely a wave property. The same effect occurs for sound or other waves crossing between regions of differing dispersions. All you need is a region where the wave has an exponential physical form separating regions where the wave has sinusoidal physical shapes. Quantum mechanical specific effects only occur in the measurement process everything else is simple wave behavior, (That is until you get into field equations but that doesn't apply here).

Man is a marvelous curiosity ... he thinks he is the Creator's pet ... he even believes the Creator loves him; has a passion for him; sits up nights to admire him; yes and watch over him and keep him out of trouble. He prays to him and thinks He listens. Isn't it a quaint idea. - Mark Twain
