Dark energy - Wikipedia
Scientists seem stumped to explain the acceleration of the expansion of the universe, and have guessed that dark energy is responsible. Presumably, they have found it.
When scientists grasp at straws, and guess answers (hoping that facts will fill in the truth), they are indulging in religion.

Even once we have figured out the expansion acceleration, we still have to figure out "spooky action." Which means that changing the spin of one particle changes the spin of an entangled particle no matter how far away it is (instantaneously). But, since nothing can travel across the metric of space faster than the speed of light in a vacuum, how can spooky action work?
Theists would like to glom onto the unknowns of physics and give theist ideas life. But, without further study, we really can't glean many answers.
