Faster-than-light travel

http://www.guardian.co.uk/science/20...cles-neutrinos

Surely Einstein said the Speed of Light was the ultimate speed that nothing could go faster than......
Quote:
Researchers on the Opera (Oscillation Project with Emulsion-tRacking Apparatus) experiment recorded the arrival times of ghostly subatomic particles called neutrinos sent from Cern on a 730km journey through the Earth to the Gran Sasso lab.
The trip would take a beam of light 2.4 milliseconds to complete, but after running the experiment for three years and timing the arrival of 15,000 neutrinos, the scientists discovered that the particles arrived at Gran Sasso sixty billionths of a second earlier, with an error margin of plus or minus 10 billionths of a second.
The measurement amounts to the neutrinos travelling faster than the speed of light by a fraction of 20 parts per million. Since the speed of light is 299,792,458 metres per second, the neutrinos were evidently travelling at 299,798,454 metres per second.
So the geeky scientist made a mistake right?...
Quote:
Antonio Ereditato, coordinator of the Opera collaboration, told the Guardian: "We are very much astonished by this result, but a result is never a discovery until other people confirm it.
"When you get such a result you want to make sure you made no mistakes, that there are no nasty things going on you didn't think of. We spent months and months doing checks and we have not been able to find any errors.
"If there is a problem, it must be a tough, nasty effect, because trivial things we are clever enough to rule out.......Physicists can claim a discovery if the chances of their result being a fluke of statistics are greater than five standard deviations, or less than one in a few million. The Gran Sasso team's result is six standard deviations."
So what does this mean
Quote:
"The constancy of the speed of light essentially underpins our understanding of space and time and causality, which is the fact that cause comes before effect.
"Cause cannot come after effect and that is absolutely fundamental to our construction of the physical universe. If we do not have causality, we are buggered."
Let's hope we aren't buggered.

At the speed of light, or even faster, that would hurt.

Actually, because of the tears in the fabric of the space time continuum resulting from the faster-than-light neutrinos, Planthead posted his thread first.

Re: Faster-than-light travel

Hmmm I wonder if we travel faster than light, will it mean time travel will happen? Is a pity I won't live to that day it happens.

Not mine. Although it was well received in the parralell universe it ended up in due to the tear in space blah blah blah.

But you do get points for the most easily identifiable title to subject ratio.

If time travel happens in the future then they are now here & so you have lived to that day

Re: Faster-than-light travel

Instead of firing neutrinos from here to italy, they should speed the Gotthard tunnel up in the summer

Re: Faster-than-light travel

The Italian minister of Education complimented with the scientist and said that Italy contributed with 45 million Euro towards the construction of the tunnel through which the neutrin travelled (no joke, official statement!). You could try to use that in order to avoid the Gotthard traffic

Re: Faster-than-light travel

maybe he misheard Neutrinos for New Trains..if you use a suitability silly Italian accent..
