WebThe standard cosmological model is known as Λ Λ CDM. Two of the key features of this model are given in it’s name: It assumes that the Universe has a component of its energy density driven by the cosmological constant, Λ Λ, and that dark matter is cold dark matter (CDM). The cosmological constant term is believed to be due to dark energy. WebRoger Penrose explains the basics of his theory of Conformal Cyclic Cosmology.
