Of course, here it is: 1. That the time in a virialized cloud of dust runs slower than outside (obviously) but much slower than it is required by the common gravitational redshift, and its change with distance is not quadratic (as in the common gravitational redshift) but exponential and that in the case of our universe, assuming its density were around 6E-27 kg/m3, it would produce Hubble's constant around 70 km/s/Mpc without any real expansion of space. 2. That the acceleration of the observed (apparent in this case) expansion of the universe would be 2.5E-36 1/s2. 3. That there is a lower limit of "dynamical friction" (quote since it is the Newtonian name of the effect while this particular effect is relativistic) experienced by any object moving in our universe of about 7E-10 m/s2. 4. That the "average size" of the pieces of non luminous matter in our universe, deduced from the 2.7K temperature of CMBR, assuming density of those pieces of order of 1E3 kg/m3, is of order of 1 m across.. -- Jim |

[Jim Jastrzebski] There is one more possible testable prediction that I forgot. Probably nothing that can be used to test anything in practice but it's funy so I would list it as well: it is that the predicted volume of the spacetime comes out as zero. It's because the metric tensor comes out degenerate. It is shown here (for brevity with c = 1, and angular coordinates dropped): g_uv = [ exp(-2r/R) -exp(-2r/R) ] [ exp(2r/R) -exp(2r/R) ] where R is accidentally a number equal to "Einstein's radius of the universe", c/sqrt(4 pi G rho), where G is Newtonian gravitational constant, and rho is density of space. It makes R the same as the radius of spatial hypersphere of "Einstein's universe". The cosmological constant of this universe is of course 1/R^2. Another funny thing is that this radius of curvature, and so also the cosmological constant, come out from purely Newtonian math that does not know aything about curvatures. This math was just applied to calculate the time dilation in virialized clouds of dust in the same way as gravitational time dilation could be calculated, straight from simple Newtonian balance of energies. The metric, despite that metric tensor is degenerate (which harms nobody except making spacetime geometry non Riemannian and not allowing to use metric tensor for raising and lowering tensor indeces any more) comes out quite decent as ds^2 = exp(-2r/R)dt^2 + 2sinh(2r/R)dtdr - exp(2r/R)dr^2. Of course it gets reduced to Minkowski for rR, it's null for dt = dr, and homogenous. So it seems to have all the required properties that we might want from a metric, except publishablility of course, since no physicist is apparently interested in metrics that don't produce expanding space. But I hope it might entertain astronomers as a kind of a curio: no expansion, and yet it makes the universe looking as if it were expanding with accelerating expansion; the numbers seem to come out right; it does not violate any physical pronciple including the conservation of energy; and it is actually derived only from the principle of conservation of energy, and with Newtonian math only. A genuine puzzle to me. I hope someone here will solve it. -- Jim |
