““Galaxies, quasars among them, are interpreted by astrophysicists in terms of probes that are attached to points in space and that move with these points. The increase of distances of the galaxies is seen as the growth of space. Space itself expands when galaxies move further apart. The fact that quasars move away from us indicates that new space originates in between. Conversely, the masses of the universe help to determine both time and space. We might say that space expands because of the behavior of the masses. The masses of the Universe in their joint action take the place of Archytas's staff. The expansion is caused by the initial momentum that was imparted to matter by the Big Bang.””
