I'm not sure if my interpretation is correct, but this Dirac Sea interpretaton does as far as I understand this, tell us that every energy level from -infinity to a certain energy level E<0 is filled with anti-particles. And this should be true for every single location in the universe.

Hi,
I've been studying Benford's law lately. The problem I've been getting, however, is that the anomalies compared to the theoretical values are quite big.
My last investigation was about nuclear levels between 1 MeV and -I think- 1 000 000 MeV. I got this information on this website...
Is this a possible solution to superluminal neutrinos?
Landau and Lifchitz formulated the two postulates of special relativity as the following:
1/ All laws of physics should be the same in every inertial frame
2/ There's a maximal propagation speed for physical interactions
The second...
Thank you, what is the basis for this statement? I tried to use the normal special relativity Lorentz transformaties for velocities, but I seem to get imaginary velocities.
Homework Statement
Hi,
This question is about Lorentzgroups. In my course of Relativity, we've seen a very little about representations of complete Lorentz groups but there are two little exercises, which we can do, but I do not understand what should be checked, not even how to start this...
Hi,
Now we have the "faster than speed of light" neutrinos, I was wondering the next philosophical question:
If we presume it is indeed correct they are faster than speed of light, would all observers of these neutrinos, no matter in what inertial frame of reference they are in, measure...
Well, the problem is, the big bang is a singularity in the time-spacedimensions. Special relativity indeed says we should stop the notion of simultaneity, but SR acts as if our spacetime is an Euclidic space (R^4).
As that is not the case in macro cosmology (the universe expands, so the...
As friction takes place, only in the direction the particle moves, wouldn't then friction only make the particle rotate slower (thus making each rotating circle of particles smaller), rather than moving the particles to one common plane?
Hi,
I try to understand the nebular theory (how the solar systems are formed) but I keep having problems with the flattening.
My physical intuition "feels" the flattening process should happen, but I want a physical/mathematical qualitative explanation.
What is the key physical law that...
Homework Statement
Today I did an experiment to met the light intensity, a function of the wavelength of light. I gained a theoretical model *how it should look*, which had 1 light intensity peak at lambda=1083nm.
On the other hand, I measured several peaks, 1 at ~600nm and another at ~750...
