When Maeder carried out cosmological tests on his new model, he found that it matched the observations.

They also support the idea that dark energy is best explained by the “cosmological constant,” which Einstein first proposed and is equivalent to the energy of empty space.

So far, DES has found no evidence that the amount of dark energy has changed over time — a finding that is consistent with Albert Einstein's idea of a "cosmological constant."

In fact, it is possible that all stars go through this dramatic stage of development in their youth, but that the outbursts are too short in cosmological time for humans to observe many of them.

(Loneliest Young Star Seen by Spitzer and WISE, NASA)

The empty space plays a primordial role in Einstein's equations as it operates in a quantity known as a "cosmological constant", and the resulting universe model depends on it.

The cosmological parameters are then adjusted so that all of the different clusters, with different masses and different distances, appear to be similar.

("Russian Doll" Galaxy Clusters Reveal Information About Dark Energy, NASA)

If the assumed cosmological parameters (e.g., the properties of dark energy or dark matter) are incorrect, then distant clusters will not appear to be similar, that is their sizes will be larger or smaller than expected.
