The theory doesn't match the observations, so how do we tweak the theory to match the observations - oh wait - let's add dark matter to the theory. Partial fix - oh wait - we need something to add something else to he theory now - let's add ..... dark energy.

Oh yeah, this seems to fix the theory to now match observation.

The observations do not require dark energy or dark matter to fix things. It is the interpretation of those observations via the theory that requires these entities.

Observations are theory neutral. It should be fun to try an come up with a good model/theory and if new observations break the theory, then it should be more fun to see what is a better explanation.

For many, many years, I have watched very intelligent people get emotionally caught up in defending their theories and models, when it should be a case of just moving on. They just don't make it fun.
