"The evidence for dark energy is heavily dependent on the theory of general relativity."
"Astrophysicist Ethan Siegel states that, while such alternatives gain a lot of mainstream press coverage, almost all professional astrophysicists are confident that dark energy exists, and that none of the competing theories successfully explain observations to the same level of precision as standard dark energy."
One conjecture is that this particular area of science has always been tainted by the religious implications of an existence suddenly appearing out of nothing. Perhaps a more conventional type of vacuum should be employed. Or does dark energy really pop in and out of existence...
