    It lets heat go in one direction only! That the biggest change in Thermodynamical Law since Claude Shannon. Now convert it a transistor, and with a maxwell daemon, (Quantum Weak Measurement, + Quantum Computer, + Classical Prediction Logic) and we have (possibly) a free entropy device, capable of turning waste (heat) energy back to useful energy.

    Yes its the invisible, or the mixtures between invisible and visible Higgs, that are the most exciting, because these are the ones that lead to the detection of Dark Matter or Mirror Matter, particles.

  7. Re:No they can't on LHC Homes In On Possible Higgs Boson Around 126GeV · · Score: 1
    Thats incorrect, physicist know that there must have been some like the Higgs below 1TeV, and the LHC runs at 7 TeV, soon to be 14 GeV. Even with those 7 TeV divided into 3, (its the quarks that interact not the whole proton, actual its 3+3*(1+1/alpha_strong+1/apha_strong^2...Higher terms), because of the gluons in the proton). But the interaction energy is about 2 TeV per quark, so the LHC can look for a Higgs all the way to 2 Tev, evidential 4 TeV.

    Mod that up, that would be my first guess for the social anthropology of it. Now if you bothered to get some real data, and not fake data just to match your prejudices you'd be a real scientist. Actually its a tough art just to remove the subconscious prejudices that led you to look for answers that match your own theory. But deliberate faking unforgivable.

    Sure, see ArVix: 1190.5917v2, but its,

    Standard particles E = mc^2 /sqrt( 1- v^2/c^2), a tachyon has v>c, and an imaginary mass, m = sqrt(-1) * m(tachyonic), so we get:

    E = m(tachyonic) c^2 / sqrt( v^2/c^2 -1 )

    So, m ~ sqrt (2 (v-c)/c ) * E

    E was around 20-40 GeV (Same speed was measured for all velocities, which doesn't look like a tachyon, in particular doesn't fit with the tachyon equation above).

    And (v-c)/c ~ 2.5 *10^-5

    That Gives m = 120 Mev, (or in the paper with error bounds, m~ (110 to 130) MeV

    The tachyonic mass needed for to get the OPERA result, is easily calculated and its root minus one time 120 MeV, which is impossible as the weak decays show the masses of even the tau neutrinos to be less than a KeV, and the others less than 1eV. So tachyonic neutrinos are definitely not consistent with both OPERA ad SN1987a.

  15. The named papers wrong on FTL Neutrinos Explained... Maybe · · Score: 1
    Sorry, but the suggesting that CERN and OPERA clocks are the GPS satellites and adjusting for there speed is just wrong. CERN and OPERA used GPS for accurate geophysics and timing measurement but have they own synchronized clocks in the earths frame. The fasting than light measurement isn't going to go away that easily.

    My personnel solution is that neutrinos feel a fifth force (many at low energy), and this fifth force as left a enough binding energy for the Scarnhorst effect to increase the speed of there force carrier above the speed of light. see axitronics for details.

    I like to bring hope, And to my knowledge a 'perpetual intelligence machine' has not been proved possible or impossible under the known laws of physics. Julian Baubour in the Cosmological Anthropic Principle, has demonstrated that different amounts of computation can be done in the universe accord to the class of cosmological model. E.g. GR with a cosmological constant 0, finite amount of computation in infinite time, but at no point those computation stop, machines can keep getter move efficient to squeeze the dregs out of the free energy in the universe for every, slowing to a finite sum, but never stopping. However in a collapsing universe with cosmological constant 0, the sum works that a infinite ammount of computation can be done in finite time, in themodymanic possiblity the computers reinvent themselves to be ever faster, preforming an infinite ammount of computation in finite time.

You can coldly deny the threat of death as much as you like, but cryonics don't start freezing until you've gone so the temperature doesn't matter. On the chemical side though chemical reaction normally fall as e ^ - something * temperature, so the lower temperature they long the brain lasts, temperature spreads and equalises around a substance while a chemical might miss places.

    Don't forgot that Cryonics assumes arbitrary good future technology, within physical possibility. Its a some day, not a next week. Better freezing and preservation, might make it sooner, but to make the head recoverable, you need it to have possible recognisable from the frozen state, the weighting on each of the synaptic inputs to the neurons, and where the neuron connected to. That information can survive a lot of fracturing, and a lot of other damage. With identically or neither identically neuron weighting it is if not you identical to what was you, by classical AI and theory of the Brain function. Although if quantum entanglement or the neuron itself does deep computation than firing on the sum of it inputs, then additionally structure in the Brain need to be recoverable. I've very much enjoyed TP books, more than that when you read a good author you get and idea of a mind behind it which is as deep an empathy as any. Enough to hope they hold his mind some way to be recoverable in the future.

    True He-3 need a much higher temperature than D-T. The coulomb repulsion is four times bigger, so roughly 4 times the temperature. But the advantage is that all the energy is released in charged particles, protons and alpha particles, which could be steered in a magnet field to produces thrust. A D-T fusion rocket would lose nearly 90% of its energy as neutrons, while a He-3 fusion rocket, would get nearly 100% thrust. A Daedulas type star drive isn't exactly easier through, it need to laser fuse pellets of He-3 fuel. And steer them in an immensely strong magnet field. The NIT is getting close to laser fusion, but neither is ready yet.
