... Dark energy is believed to be a component of the Universe whose repulsive gravity is presently accelerating the expansion of the Universe.€а Although it comprises the bulk of the mass-energy of the Universe, its nature is not well understood.€а €аAlbert Einstein originally suggested its existence about 80 years ago. A supernova is the explosive death of a star, which unleashes a burst of light through the cosmos. ... This website is a gift from Nancy Riess . ...

Tired light models invoke a gradual energy loss by photons as they travel through the cosmos to produce the redshift-distance law. ... The tired light model can not produce a blackbody spectrum for the Cosmic Microwave Background without some incredible coincidences. ... So the CMB must have come from a far away part of the Universe, and its photons will thus lose energy by the tired light effect. ... Assume that the CMB starts out as a T = (1+z)*T_o = 2.998 K blackbody, which is the blue curve. ...
