Hahaha - the way we've been flip-flopping on neutrinos, it seems entirely appropriate to me! :smile: But thank you for answering my questions - the fact that it's really hard to push a neutrino (or to drain it of momentum) seems explains a lot about why we still don't understand much about...

...shouldn't it: 1. become asymptotic to c as you pump more energy into it? 1a. don't I need to a lot more energy to move it a little closer to c? 1b. can't I compare it with a beam of light to confirm that light is faster? 2. be able to come to rest as you take energy away from it...

in one of the videos about OPERA, I saw a mention of fiber carrying light along the path - assuming that this light is subject to the same mass distributions as you ghc mentioned, couldn't you work backward with this fiber as the calibration point for c, and determine if the neutrinos have...

Here's an interesting interview with Ereditato & Autiero posted on Youtube: (not many details about the experiment itself, but you can see how open minded they are about the results...) This one gives a broader description of CERN's neutrino experiments/OPERA (for those of us without...

nice observation! Now, I wonder how they came up with an error of 10ns - any mention in the paper showing how the systematic error was actually calculated?

Hope has nothing to do with it... Instead, the nature of experiments suggests the possibility of being wrong somewhere in measurement of error is much higher than an experimental result disproving a well-established theory (however exciting that possibility may be!). At this level of...

There's an interesting article here regarding errors in GPS which could explain the discrepancy: http://www.wired.com/wiredscience/2011/09/neutrinos-faster-than-light/

Nice link. TY. Another M5.8 off Fukushima at 21:55PM. I don't know how anyone in Japan can get any sleep - if it's a really big one, you wouldn't have enough time to wake up and compose yourself enough to attempt an escape. With so many aftershocks, how could you distinguish the difference...

NHK just reported an earthquake Chiba, Ibaraki, Saitama, Tokyo, and Kanagawa. Looks like a 4 on the Japanese scale in Chiba, 3's in Tokyo - M5.8, but no chance of tsunami. Centered off Chiba. Around 9:21:32PM Japanese time. Looks like still plenty of aftershocks.

Actually, speculators are buying JPY because they are using the Kobe Earthquake as an indication of what will happen next. In that case, there was repatriation of foreign (non-JPY) currencies (sell foreign currency, buy JPY) to invest in reconstruction, so hedge funds are stepping ahead of this...

If the reactors are assumed to be lost, can some material be dumped on top of the entire site so that should explosions occur, the spread of radioactive contamination can be limited? From my layman's viewpoint, it seems to me that officials are just reacting to what is happening rather just...
