Consider now the FLRW metric with a positive cosmological term and homogeneous density - that is to say the [LAMBDA]CDM model.
The cosmological term then becomes a ratio of photons to photon holes.
This lends support to the fact that only a 4th rank tensor theory can strictly describe a metric with a variable cosmological term.
In addition, it implies a non zero cosmological term and a constant scalar curvature, therefore it doesnot admit a Hubble expansion in the whole, which tends to contradict all current observations.
We then include a variable term that supersedes the socalled cosmological term Kgah in the field equations, still complying with the conservation property of the Einstein tensor density in GR;

Next making use of a max quantum cosmic cosmological term (lambda) we obtained the mass of the universe, which now appears quantized in the units of cosmic [[?
In the first one we used an exponential cosmological term, for the second one we considered vanishing cosmological constant.
Its great brightness and protracted visibility is largely a result of its relative proximity in cosmological terms.
Furthermore, the new observations indicate that the bright starbursts in these distant galaxies last for a mere 100 million years - a very short time in cosmological terms - yet in this brief time they are able to double the quantity of stars in the galaxies.
It took just a few thousand years - a mere pinprick of time in cosmological terms - for large, complex organic molecules to evolve in the gas shells remaining, astronomers said.
We have, it is true, no direct evidence that Zeno thought of Eros in cosmological terms.
