Like the title says; 'We have broken speed of light' claim .. It would definitely lead to some bizarre consequences as mentioned in the article. Arriving somewhere before even leaving got my mind a bit twisted though, but I guess what they mean is that because we need light in order to see things, we would see the thing that moved at it's new location before the light of it's old location is totally exhausted so to speak. Cool stuff, can't wait to hear if it's all true and accurate, it would be big news that's for sure, Cheers

somehow in my article they didnt violate einsteins rule, and the people in your article did... I dont quite understand it all need to do more research. At least you can not see yourself appear before you start because the distance the light must travel is too big before reaching you in time before you left. At least I think, that's how I understood time travelling so far...

Pretty skimpy article for so much hoopla. As others have said, the speed of light is "broken" in many instances... heck you can do it as well... simply take a flash light, point it out and spin spin spin! The radial velocity of the light beam is faster than "c"...watch out that you don't blind your grandpa in 1930 or he'll never marry your grandma!!! However as others have pointed, you can't use any of the knonw FTL to transfer information and thus it is a semantic word game at best with (AFAIK from the aritcle) no practical use whatsoever. Two other factoids: 1) The speed of light has always been broken in quantum tunneling for that is instantanous. Whether it is truly instantanous or merely too fast to measure I'm not sure but the fact these german cats where working with quantum tunneling leads me to belive they haven't found anything we didn't know. 2) Relativity DOES NOT prevent the speed of light from being broken... only that a massve object cannot be accelerated to the speed of light. In the cracks of that definition, namely that it needs to be massive and accelerated, you could find room for all manner of FTL including massless transportation and non-accelerated motion (as per the Alcuberrie Metric for example)

That was an ingenious joke! Hahaha
But if you can send things FTL, and really meassure the signal on the other side (else how did you know it was FTL?) then transportation of data is already possible right? you could sent signals on time intervals, and depending on the time it arrived determine what data has been sent...

It's not a joke. That's true.

Nope. The fact is that measurement is a form of information hence you can't measure a FTL signal. You know it's there, but you can't touch it in a sense.

You're not gonna tell me your grandpa never did marry your grandma because you stick your flashlight into the washmachine well I guess that if lightwaves went back in time by spinning a flashlight, the effect would be minimum. Else you would see a flash on the wall before you even rotated the lamp! I swear I never saw that happen. Even if you would spin a flashlight around near the speed of light, I doubt you would see a flash a few seconds before the machine starts spinning.

Can't they slow it down first by colliding the particle with something materialistic? thats kind of odd then, but a pitty I know too few about this subject to start a discussion about it.
