The Mythical Tunnel Between CERN and Central Italy

fph il quozientatore writes "Mariastella Gelmini, the Italian minister of Public Education and Scientific Research, complimented the researchers for the recent (supposed) discovery of faster-than-light neutrinos. Her press release mentions that Italy funded the construction of a 'tunnel between the CERN [in Geneva] and Gran Sasso [the labs in Central Italy].' Google maps reports the distance between the two labs as over 900km — but of course once the tunnel is open to traffic the trip will be much faster."

      Your argument has some issues. First, the speed of gravity is theoretically c. This can be proved experimentally sometime soon. Or was. I forget. Since entropy is ambiguous in this thread you forgave me I'm sure.

      Neutrinos are believed to have mass of some kind, because they appear to experience time. Neutrinos are believed to cycle over time through electron, muon and tau neutrino flavors - and cycling at some time rate based on energy levels. If the mass of neutrinos is negative it becomes a different theoretical problem with neat solutions. The Neutrinos would be repelled by, rather than attracted by, gravity. Yes, causality remains a problem in this case if the speed of light is truly broken and the observation isn't an error, because of the potential for heavier particles of greater mass and potentially much greater speeds. The actualization of negative masses does help certain other aspects of the theory though. Perhaps the red-shift of neutrinos and their higher-order cousins caused the early FTL expansion of the universe, and they're what's now slowing it down. In that case the missing mass in the universe is the negative mass of the neutrinos that expanded the universe faster than c on their way out and are now opposing the expansion of the universe with their negative mass. That would make the net mass of the universe exactly zero, which would clean up a lot of mess in the math. Energy then becomes the potential between mass and negative mass, the speed of light the dividing line between (which makes sense, as light is massless energy). Energy becomes the attracting force that pulls the negative and positive masses together again in the end. The gravity force becomes the equivalent of energy shifted into the mass dimension. Our entire universe becomes a temporary twitch in higher-order math: a ripple in dimensions beyond our ken - a single bubble in a fleck of foam on the crest of a wave on an endless sea made turbulent by winds beyond our imagining, that blooms once and bursts or shrinks again, absorbed by an uncaring sea. Its duration would be the level of incursion of one higher-order plane on another.

      Since the neutrinos and their higher-order negative mass FTL cousins experience time in what we would consider the reverse then naturally our big bang was their big crunch. Our big crunch will be their big bang. It would make sense that the positive masses exactly equal the negative masses, that the highest density of mass in this negative mass universe is exactly the same magnitude of ours (galactic core black holes with negative mass) and that though from our current view of time their mass inhibits ours by being outside our known universe's perimeter pressing it in, from their point of view we are the negative mass preventing the expansion of their universe, and presently pressing it in toward its end. Time starts and as the masses and negative masses disassociate on their grand loop, time slows until it reaches some apogee prescribed by its cause and stops, and then reverses gaining speed until it meets its opposite mirror and stops. It's grand symmetry, and it would make perfect sense if my perfect mirror were posting this comment on gro.todhsals out there somewhere, though it's not necessary for that to be true for the math to work out.

      This may do away with the the cyclic inversion theory, or "string of beads" because time itself loops back with its opposite and the beginning is also the end. There may be exactly one, which cleans up a lot more math.

      Really, who needs causality anyway? It's getting in the way of a lot of interesting stuff.

      If the mass of neutrinos is an imaginary number, well, things get a little fractal from there as the picture gets more beautiful and more inscrutable.

      Doesn't work with matter-antimatter annihilation (unless we work out what that means in terms of time-anti-time annihilation), but it was an interesting revelation in physics class.

      Sure it does - it's the mass-energy equivalence principle. If you look at matter-antimatter annihilation in reverse, you see two gamma rays colliding and producing an electron and positron. Momentum, energy, charge, and all the important parts are conserved. This idea is what makes particle accelerators work. If you get enough energy together, then any particle can be created, as long as it conserves where it matters.

      Correct. The neutrinos traveled through solid rock. Neutrinos don't interact with much so as far as they are concerned solid rock isn't a big deal. And you actually want to have the solid rock there. You wouldn't want an open tunnel- the process that creates the neutrinos creates a lot of other particles of all sorts of different types. But all of those get blocked by the rock. The experimental setup in particular needs to block both the muons and tauons. These particles can normally penetrate a lot o the point where stray muons from cosmic ray collisions are a major nuisance for sensitive neutrino detectors even when the detectors are deep underground. The Japanese big neutrino detector Kamiokande has a lot of special equipment to deal with just this. So in this case, having many kilometers of rock is necessary to let the whole thing work otherwise the stray particles would make it impossible to detect neutrino interactions with all the noise.

    Gran Sasso is a mountain in eastern Italy. About 25 years ago, a tunnel (of the traffic kind) was made underneath the mountain. Physicists saw this as a great opportunity to build a particle physics lab, using the mountain as shielding from cosmic radiation. Usually such experiments (such as dark matter detectors) are placed deep underground in hard-to-get-to mines, but this lab is great since you can literally drive up to it. The lab is comprised of three (very) large sections that are right off of the main road.

    Italy paid for this tunnel and the carving out of the lab space. Maybe she was confused or maybe the translation was poor, but Italy did indeed fund the construction of the tunnel underneath Gran Sasso as well as the laboratories underneath the mountain. So give them credit there.
