The results sound interesting but I think I'll wait for the validation/verification/replication. The media seems to have jumped on leaks and the scientists felt compelled to rush their findings before THEY really had a chance to do their crosschecking.
Plus I have yet to find an actual *science* article describing what they've found, its all been like Joe Reporter Who Majored In PoliSci Waves His Arms.

There's a lot of buzz about this, certainly. I don't know enough physics to start explaining this to anyone, but from what I've read so far, this is massive if true. Finding out that gravity pushes and not pulls would be analogous.
So treat this with the utmost skepticism. Here's an article on BadAstronomy about the subject. The author has looked at their paper in arxiv, and the reasoning looks solid to him. BadAstronomy The paper on arxiv

Well they are searching for their "errors" since marsh I believe, now they ask international help. It's really rare honestly, people where all hyped where I study about that.
Spoiler for the conclusion ... in short:
Well I barely understand what's written here, physics aren't my field but it seems ... possible. Well let's take it slowly, it's not really a such major change right now, the same newton physic is still applicable on certain field, Einstein's one will always be on infinite small. |

I'm still reminded of an acquaintance of mine that got absolutely furious with me because he couldn't use Relativity to debunk my claim that the speed of light isn't as fast as the speed of dark. To this day I question the quality of his physics major.

Wouldn't the "speed of darK" equal the speed of light, as for it to be dark, the light has to leave, and it can only leave at the speed of light. You can only have an absence of light at the speed it takes for light to be removed.

To answer your question with the same logic I used against him, the problem is that you can't quantify dark. It's like infinity or omnipresent. Yes, we know infinity means "it goes on forever", but it's an intangible concept. A light beam is made up of stuff, just like air is made up of stuff. Those are tangible and can be quantified, even though we used to believe otherwise. You can see dark, but only in the context of light. You can picture infinity, but only because of finality. You can picture omnipresence, but only because space is a tangible concept. What is nothing? The absence of something. However you can't measure nothing, while you can measure something. This does not mean nothing exists, but only that you have no way of proving or disproving it. At best you can define nothing around something, for instance you can define the lack of something in the area of something. However, you still cannot quantify what the nothing inside that something is. And upon rereading what I just wrote.... Oh that is good. I'll remember that one.

What do you mean by "dark"? Darkness as when there's no visible light?
Because it's impossible to create total darkness, each body (even no-living body) emits heat based on gamma and infrared rays which are light even if they are all of the time invisible to the human's eyes. If you mean by when there's no visible light, indeed it doesn't have speed, it's here to begin with and only when there are objects that absorb and emit light visible waves, it's "bright". Well I don't really know how to explain this, i'm not used to talk about physics in english, I prefer talking about anime haha. |

Net Neutrality Rules Published, Lawsuits Soon to Follow
"The FCC has finally officially published long-delayed rules prohibiting cable, DSL and
wireless internet companies from blocking websites and requiring them to disclose how they slow down or throttle their networks. The so-called Net Neutrality rules (.pdf), passed along party lines in late December last year in a 3-2 vote, were published in the Federal Register Friday and will go into effect on November 20."

But dark is different. Dark exists where light does not, and light is limited in source and duration, while dark is not. In the absence of light, can you describe how quickly darkness travels? Does it travel? Can it travel? We acknowledge that dark exists, but we also define darkness by what it isn't. It's the exact definition you apply to infinity or omnipresence. It has no end, and no beginning. It just is. Think about it like this: To an observer, if I left and arrived at the same time, did I go somewhere very quickly, or nowhere instantly? Quote:
