My understanding is that except for the second law of thermodynamics, the laws of physics work equally well in either time direction. See: http://en.wikipedia.org/wiki/T-symmetry
The second law of thermodynamics says that the entropy of a closed system increases with time. The universe is...
Can you provide a link or reference for this statement?
If antiparticles exhibit the same decay rate as the corresponding conventional particles, it would confirm that they are behaving with the same direction of time.
Much of the development of physics has been related to making the equations easier to work with.
It is possible to work out celestial mechanics with the Earth as the frame of reference, but the equations get really ugly because the Earth far from an intertial frame. A breakthrough occurred...
According to Feynman's interpretation, antimatter is essentially the same as conventional matter only it is moving backwards in time. Thus an electron-positron creation is really an positron moving backwards in time, interacting with a photon, and then moving forwards in time so that the...
Is an "anti-universe" possible?
By anti-universe, I mean a universe where anti-matter dominates over matter and the direction of time is reversed. My understanding is that one interpretation of antiparticles is that they are the same as regular particles going backwards through time.
If a...
