Reply to comment by nogzila in The Nancy Grace Roman Space Telescope - the next major step in astronomy that will help unlock the secrets of the universe's expansion and dark energy. by upyoars

The thing that bothers me is that they never "go back to the drawing board" and instead choose to "tweak the current theory" x500 times. Doesn't seem very scientific, and reminds me of Luminiferous Aether or Quintessence. The descendants of those 16th century scientists are still marching around waving their hands, they just wear a different style of hat now

They can’t do anything more with dark energy until it is “found/discovered”

It’s just a hypothesis because they know there is something there that’s doing something about the expansion. Until dark energy, whatever it may actually be, is found it is just a sort of variable in a math equation.

There are lots of people going back to the drawing board every day, but so far none of them have found a better model than Lambda-CDM. Certainly not for lack of trying, though.
