Contemporary philosophical debates often address Kant's concept of practical freedom, but here scholars of philosophy explore receptions of his concept of cosmological freedom.
So he introduced a term, later dubbed the cosmological constant, which represented an antigravity force that countered the contraction.
The team located the positions and lensing signals of the dark matter halos and found indications that the number of halos could be inconsistent with what the simplest cosmological model suggests.
This flies in the face of the standard cosmological model, which predicts less than 1 percent of all satellite galaxies should show this synchronous behavior, the rest moving in random orbits and directions, due to the effects of factors such as the presence of dark matter.
where A is the cosmological constant (assumed to have a very small value).
Both mentioned cosmological constant problems can be considered in the framework of the extension of the standard cosmological [LAMBDA]CDM model in which the cosmological constant (naturally interpreted as related to the vacuum energy density) is running and its value is changing during the cosmic evolution.
The standard Lambda Cold Dark Matter (LCDM) model [8], managed to constrain down to a few percent cosmological parameters such as the Hubble constant or the total amount of matter contained by the Universe.

Such consideration suggests not only that selection may be the fundamental source of order in the universe--essentially, the opposite of the entropic process--but also that intelligent life is more likely than any other known thing in the universe to be an adaptation designed by cosmological natural selection.
Recently, the authors of [26] showed that this kind of interaction is favored by current cosmological observations in an extended ACDM model.
If their moral purification leads to a metaphysical interpretation of Plato's theology whereby Plato's gods or supreme God becomes identified with the Form of the Good as the highest metaphysical principle, then the tendency to preserve their anthropomorphism leads to a cosmological interpretation that sees the gods as "personified forces responsible for bringing order to the sensible world." In Van Riel's assessment, these countervailing tendencies ultimately culminate in the introduction of the unmoved mover in Aristotle's Metaphysics, "even if there is a plethora of Platonic gods, they need to be hierarchically subordinated to a metaphysical principle on which all other things depend."
The Cosmic Microwave Background (CMB) is the oldest light in the universe, and its study has allowed scientists to accurately measure cosmological parameters, such as the amount of matter in the universe and its age.
