From what I understand and please correct me if Im wrong, but havent we only observed Dark Energies effects and not actually detected what its made up of?
As I understand our present knowledge of dark Energy, there are three competing explanations or theories
1} the Cosmological Constant,
2}Quintessence
3} Illusion
with the third, illusion, bieng a breakdown of Einsteins theory of gravity in large scales, the gravity theory that I was referring to.
And Quintessence, bieng some kind of unidentified energy field in space.
Please enlighten me as I love to learn about this stuff!
Im so far behind in this that its sad.
another question, have scientist absolutely solved the redshift competing theories I think that I read somewhere that there was some kind of debate as to the accuracy of the doppler effect especially if dark energy has'nt been completley identified, could this exotic effect have an adverse reaction to the Photon energies over a large distance scale?
Im really not up much on Cosmology or Particle Physics.
