Do we even need dark energy to explain cosmic expansion?

Three mathematicians have a different explanation for the accelerating expansion of the universe that does without theories of “dark energy.” Einstein’s original equations for General Relativity actually predict cosmic acceleration due to an “instability,” they argue in paper published recently in Proceedings of the Royal Society A. Paper. (public access) – Joel Smoller, Blake Temple, Zeke Vogler. An instability of the standard model of cosmology creates the anomalous acceleration without dark energy.

Well, if we don’t need dark energy to account for cosmic expansion, isn’t that a bit like not needing Santa Claus to explain the wine, cheese, and chocolates under the tree?

Perhaps stubbornly contrary evidence merely shows the need for more drive and zeal in generating new naturalist theories, not more reflection and evaluation of that direction.
Supernova analysis questions dark energy cosmic acceleration
Take back Nobel prizes for accelerating expansion of universe? Dark energy might be an illusion say some researchers. But we thought only a denialist was allowed to doubt the accelerating expansion of the universe. Rules change?
Expanding space bubbles could doom dark energy? Is it possible that the sheer ability to make up theories without consequence is adding to the confusion?
Dark energy made by black holes? But do we know that dark energy actually exists? Finding some would help us decide whether to cheer on or deprecate the revolution.
