Little fixes to SR and QFT can’t account for gravity either. If (big if) neutrinos can travel FTL, then they probably weren’t boosted there by EM force alone.
When we integrate Friedmann’s equation with cold dark matter and dark energy, using the standard LCDM model, we get a space with a radius...
All velocity measurements are ultimately coordinate system dependent, and that includes those of light. Nevertheless, we aren't talking here about the velocity of light per se; we are talking about the velocities of neutrinos, electrons, and positrons. Specifically, we are talking about the...
The Cohen-Glashow paper predicts that electron-positron pairs will be produced if and when a neutrino exceeds the maximum attainable velocity of the electrons and/or positrons. Their analysis does not depend on the interaction of neutrinos with a medium, or on the speed of light in the medium...
The Cohen-Glashow paper, in view of the ICARUS results, implies that, should the FTL neutrino results be confirmed, then electrons and/or positrons would have to be capable of FTL travel as well.
The CMB frame is an interesting landmark, but the CMB photons are not randomly distributed photons. They represent the temperature of a surface that is visible from every direction; a spherical surface (of last scattering). Every enclosed room has a similar field of photons that can be measured...
If you were at rest in the center of any black spherical shell of reasonably uniform temperature, you could measure a spectrum for the blackbody radiation that would be originating from any point on the inside surface of the shell and there would be no Doppler anisotropy regardless of what...
stglyde,
You can't properly apply LET to the CMB any more than someone else could properly apply the standard formulation of SR to a simple problem involving gravity here on earth.
GR is the proper tool for dealing with gravity and the CMB, and GR lets you choose any coordinate system that...
LET is exactly the same physical theory as is the standard formulation of SR, but it uses a different coordinate system. Both LET and SR are similarly limited to application within small space-time regions.
If the OP really does, as you say, "believes in a single 'absolute' LET rest...
The comoving frame in which all observers see a homogeneous and isotropic universe could also be considered as such a universal landmark frame. So, which one is "the aether" frame? Neither one really, but in the transition to GR some of the sterile concepts of SR get relaxed.
LETists don't have any better telescopes than do the SRists. Both would have to look into a GRists telescope if they wanted to understand things like the CMB for example.
You need to use GR if you want to understand the CMB. The CMB is not "the aether". The CMB is a field of photons that were...
Some details about how the OPERA team synchronized their clocks is given on the first half of page 9 of the paper. I am not otherwise familiar with this particuar method that they used to synchronize their clocks.
Einstein's clock synchronization procedure involves an exchange of signals at...
Although it would be nice to be able to send a laser beam along the neutrino path between CERN and Gran Sasso, this is not necessary. By accurately measuring the distance between the two points, and by synchronizing the clocks properly, then the speed of light in vacuum between the two points...
No.
It right, then it would be something new, but nobody knows for sure whether the result is right or wrong. It will have to stand up to the test of time before anyone can know that.
