Frontiers of Physics

Alexander F Mayer has a very thought-provoking website. The basic idea is the Einstein neglected a small transverse relativistic effect and the consequences of that neglect. He also points out that the notion of a history of the universe is a meaningless statement. I have heard this before, but never understood it until his presentation. The argument is as follows: Mass bends spacetime. Because there is only positive mass, spactime bends in one direction. The distribution of matter is quasi-isotropic. This causes the structure of spacetime over large scales to appear like a 4-sphere with time always orthogonal to surface of the sphere. Time will in general over large distance be pointed in different directions and we will see distant galaxies as aging slower, just as they see us as aging slower. Distant objects will always be redshifted without any motional relativity. The idea of curved spacetime also leads to a horizon for all individuals in the Universe beyond which objects are
