The acceleration of the Universe can be seen in the redshifts of distant supernovae. |
In excited atoms, energy radiated as photons eventually leaks into the vast interstellar spaces and redshifts away. |
The evidence that is the most difficult to explain away is the quantization of the cosmological redshift and the non-Doppler nature of quasar redshifts. |
In order to be visible at all at the huge distances implied by their redshifts, quasars must produce prodigious amounts of energy. |
To be able to detect these very distant objects which were forming near the beginning of the universe, astronomers look for sources which have very high redshifts. |
In the present study the distance modulus was adjusted to take into account the effect of redshifts on the observed fluxes of astronomical objects. |
