Therefore the BAO technique helps constrain cosmological parameters and provide further insight into the nature of dark energy.

The first results from this mission, disclosed in 2003, were detailed measurements of the angular power spectrum to below degree scales, tightly constraining various cosmological parameters.

The result was an improved power spectrum of the CMB, going out to a multipole of 1400, and refined cosmological parameters.

Some work has been done attempting to use radio galaxies as standard rulers to determine cosmological parameters.

Observational constraints on halo concentrations imply the existence of theoretical constraints on cosmological parameters.

"CDM halos must have cusps, so the stated limits hold and provide new constraints on cosmological parameters."

Additionally, this method constrains the uncertainties on some cosmological parameters from a powerful new perspective, which adds certainty to our standard model of cosmology.

Any fine-tuning of cosmological parameters weaken the independency of the fundamental theory.

Philosophically, it can be assumed that in the early time, there has not been any agent to tune the cosmological parameters.

This in turn constrains the properties of dark energy and other cosmological parameters.
