  • Bad news for OPERA.

    Confirm, after I fixed some error-analysis ( — binomial coefficient and error analysis) and fixed the speed-of-light-unit calculations I see that OPERA-experiment does not even need to look beyond what error they might have done. ~1 part per billion of eV (ppb) error on their neutrino-mass equivalent to ~274 ppm of 1 eV error on…

  • A tip on speed of light units

    A major advantage of Physics in terms of speed-of-light unit is we do NOT have to deal with huge numbers if we are to make a down to the pen and paper calculation. This is possible because speed of light is a constant even though a large number. So you can compute everything as if…

  • The physical meaning of Schwarzschild Radius. Flyby, Pioneer and OPERA anomaly.

    since we are using light-speed in our theory we must make an error at the order of S-radii since by definition S-radii is the distance over which the relevant-mass does not let even light escape (read the linked article above and here: All masses behave like black-holes to some extent). SO thats (S-radii) the minimum…

  • Moving clocks run faster in the Doppler hemisphere of approach

    Moving clocks run faster in the Doppler hemisphere of approach, run slower in the Doppler hemisphere of recession and run slower in the Doppler plane of intersection of hemisphere of approach and recession. The GPS satelites eg are in constant free fall towards earth and located in the Doppler plane of intersection, they never approach…
