Is It Time to Rethink Our Models of Dark Energy and Dark Matter?

Click For Summary
SUMMARY

The discussion centers on the justification of studying dark matter and dark energy, which constitute 68% and 27% of the universe, respectively, in relation to the known matter that makes up less than 5%. Participants assert that distinct models exist for dark matter and dark energy, informed by but separate from normal matter models. These models focus on energy rather than matter, as general relativity and quantum mechanics primarily address energy fields. The discovery of dark matter stemmed from discrepancies between observations and predictions made using existing models.

PREREQUISITES
  • Understanding of general relativity and its implications on energy and matter.
  • Familiarity with quantum mechanics and energy fields.
  • Knowledge of cosmology, specifically the composition of the universe.
  • Basic grasp of observational astronomy and its role in discovering dark matter.
NEXT STEPS
  • Research the latest models of dark energy and dark matter in cosmology.
  • Explore the implications of general relativity on energy and its relation to dark matter.
  • Investigate quantum mechanics' treatment of particles as waves in energy fields.
  • Study observational techniques that led to the discovery of dark matter.
USEFUL FOR

Astronomers, physicists, and cosmologists interested in the fundamental structures of the universe and the distinct models governing dark matter and dark energy.

Hey guys,

I was wandering that, if dark matter and dark energy makes up 68 and 27 percentage of the the universe, then is it justifiable to study these in terms of models of the known parts of the universe which comprises of less than 5 percentage of the universe, also it is clearly evident that nature prefers dark matter and dark energies to the rest, so should there not be a completely different model to describe it altogether?
I admit that this is a highly non-technical question, and may even sound absurd to some of you, but I found it to be interesting to think about, and would love to hear your personal views about it.

Thanks in advance.

We don't study these in terms of models of the normal matter. Dark matter and dark energy have different models. These models are informed by our models of normal matter, but they are distinct.
 
The models now are based largely on energy, not matter. General relativity only cares about energy, it doesn't matter to the equations whether it's matter or dark matter or even a black hole. QM also deals with energy, particles are just waves in energy fields. So neither are really a model of matter.

It also makes sense because we used those models to discover them in the first place. The only reason we know the dark matter is there at all is because our observations don't match predictions.
