"The readings have so astounded researchers that they are asking others to independently verify the measurements before claiming an actual discovery."

Do you have one of those "They say" shirts?

Wait till it's confirmed, I find it funny when a theory comes out some people immediately think it's fact and then there are other who still think evolution is still in the theory phase.

Did you happen to miss the date of the article I posted? It's the very first line in the quote.

987587968775439193 miles in 168,000LY

60ns in 454 miles (CERN) --> 130518233758868615 ns in 168kLY = 130518233 seconds = 36255 hours = 4.13 years.

from silver pig's article
the SN 87A events were electron neutrinos, not muon neutrinos, and they were at substantially lower energies. If neutrinos do violate the light barrier, it’s completely consistent to imagine that they do so in an energy-dependent way, so the comparison is subtle.

I wonder how they came up with this? How do they know for sure how fast the earth is actually travelling in absolute terms? If they get the direction OR the velocity wrong it would throw off all their calculations. Yet 10 nS seems like a pretty tight range. Light only travels 10 feet in 10 nS.

they probably use an atomic clock.

60ns doesn't sound like a huge time difference. Light is also known to travel at different speeds through different mediums. Seems like it could be possible that our known max speed of light isn't the actual max. Then again, these scientists are a lot smarter than I am....

i always wondered how some college kid born at the turn of the 20th century could figure out everything about the universe with no real science tools to help.

and more and more, he is getting dis-proven. he had it very close, but actual research is proven him slightly off time and again.

i think this is awesome news too, because maybe we could just shoot neutrinos into whatever direction we want as a form of communication. control the landrovers on mars in real time, you know?

The speed of light has a max, through a vacuum. We know the speed through almost every medium.

With all this said and done, is fiber optics now obsolete?

We'll be sending neutrinos through special tubes instead. The internet really WILL be a series of tubes! :biggrin:

The VAST majority of neutrinos pass through the entire earth without interacting with anything. Neutrinos can pass through light years worth of mater without interacting with a single particle. That's why they are call neutrinos, from the Italian equivalent of "little neutral one". The only reason we can detect them is that we use very large detectors, usually thousands of cubic feet in volume, and only detect a VERY VERY small percentage of the neutrinos we are looking for.

Wait, what? Are you talking about Einstein? Some college kid? I don't think you quite understand the paradigm shift he enabled. And I'm not sure what you mean by "more and more, he is getting dis-proven". This is a single, un-replicated study. Virtually every other good experiment ever conducted has confirmed Einstein's theories of relativity.

I also don't think you quite understand the consequences of faster-than-light travel of neutrinos. Also, control land rovers in real time? This study, of correct, shows neutrinos a little bit faster than photons, not insta-travelling across space.

Good luck getting neutrinos to follow the path you want considering they're weakly interacting, and fly straight through entire planets without noticing.

so at 60ns faster than the speed of light over 454 miles...it would travel 59 feet further than light over the course of 1 second...correct?

No, light is much more practical.

However since moving faster than light means in other reference frames the detection of the particles happens before the emission, we could use them with a very low transfer rate to signal backwards in time.

Can't believe nobody has posted this yet. :rolleyes:

Interestingly enough I can see it being possible to put to practical use the weirdness of neutrinos many many many years in the future.

The lower bounds of routing a packet from New York USA to Perth Australia is around 93ms. This requires a direct cable that travels the distance in a perfectly strait line. 186ms round trip latency minimum.

Using "Neutrino Routers" and just shooting some particles strait through the earth puts the one way time at around 43ms. While still not completely ideal, its nice to imagine a world where round trip latency to any location is under 90ms. I know neutrino detectors are bulky and expensive, but at least its slightly more feasible than drilling through the core of the planet.

Tesla said that neutrinos would travel faster than the speed of light almost 80 years ago but nobody believed him.
