Okay. I guess I was just thinking of the electron - muon - tau, each generation more unstable than the other, but maybe that doesn't necessarily follow.

Wow, I would think they would be extremely unstable. Any models to suggest decay times on such things?

Thanks for the explanation, also the link to the other thread. I'd always heard that any new generation would have to involve the other leptons, but didn't know why. Is there anything else other than anomaly cancellation, which would be satisfied by adding the additional particles, that might...

Maybe this thread is a bit old, but here goes. What would the discovery of a 4th generation of quarks do to the Standard Model? It's my understanding (non-physicist) that three generations fully satisfies SM. Is there even room for a 4th? And, if a 4th generation of quarks is found, would...

Can anyone describe what technique would have been used to determine the chord length through the Earth between the two surface points? I suppose it's a commonly used technique, but I'm curious because the Earth is not a perfect sphere and each point is at a different altitude. Seems like it...

By my admittedly crude estimation, it would take a proton beam density ~306 times greater than theirs to achieve a similar neutrino detection statistic (assuming a linear beam dispersion but that seems safe). Or, the detector would have to be 306 times larger in area. This is using their...

Curtain #1: Neutrinos are faster than c. Curtain #2.: A group of very careful, smart human beings have not yet found a subtle problem in a very complex system (or study design). While the jury is still out, if I were a betting man, I think I'd bet on curtain #2. Either curtain is sure...

This morning's Dario Autiero seminar video link was posted on post 187, but it was apparently not available at that time. Here it is again. http://cdsweb.cern.ch/record/1384486" It should answer a lot of questions asked here concerning methodology, etc,. in addition to the paper.

My background is engineering, not physics, but frankly, the method used to correlate the proton extractions with the v detections doesn't seem that bad to me so far, although at first blush, 16,111 detected events doesn't seem too great statistically. I'd like to see more expert comments on...

Thanks for clarifying that. So now that the paper clears that up, it appears the photon can resume it's original svelte, speedy status as "c". This sure is starting to look like an error in position measurement. Not as much fun, but still would be important, since they must have been...

Whether this is an error in methodology/measurement or it is verified that neutrinos are faster than photons and photons are slower than c and massive, etc., the outcome should be very interesting in any case. This group is not stupid and have had 4 years to figure this out. It seems to me...

f95toli: Very interesting information. Thank you. Does all this imply that materials people are giving up on developing inherently malleable materials? That is, are we stuck with ceramics? I've always hoped that some niobium alloy-like material could somehow be found. Or perhaps the...

Which leads back to the Big Problem in developing practical high temp superconductors: So far, all high temp superconducting materials have been non-malleable ceramics which cannot be made into practical wires for conventional windings, at least the last time I looked. Can anyone bring us up...

Evo: Thanks for the example of what goes on behind the scenes. As for "Pay as you go" service, I guess you would see a metered scheme per GB or something, as we pay for other utilities such as electric. Remember when nuclear was going to be so cheap it wouldn't be metered? Actually, as a...

I should clarify a few things here. First, I mentioned a report from IBM. That should have read AT&T. Here is a news report referencing that: http://news.cnet.com/2100-1034_3-6237715.html Thanks Evo for correcting my misuse of the term backbone. I probably should have said "internet" and...
