In that scenario, a redshift
in light would be explained by the distance between a star and its observer, with the light slowing over great distances.
Ted Forte replies: Distance estimates made by different methods often vary greatly for the same object--and, as you've noted, redshift
can be most problematic to interpret.
6) is our cosmological model relating light-travel time to redshifts
Another recent Hubble survey also found a handful of faraway galaxies with redshifts
possibly in the range of 8.
When measuring distant objects in the Universe, astronomers refer to the redshift
using the letter z.
Quantization and Anomalous Redshifts
Tifft returned to research on galaxies, combining his data on the brightness and color of Virgo cluster galaxies with data on their redshifts
The Friedmann equation expresses H as a function of redshift
When compared with lower redshift
studies, the new results show that the number of galaxies grew steadily as the universe aged.
The group plans to seek larger samples of quasars, to confirm the patterns are consistent and can be used to calculate their redshifts
everywhere across the universe.
Objects with larger redshifts
are farther away and are seen further back in time.
The table gives travel times for various redshifts
based on an age for the universe of 13.
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.
By far the most intriguing result of these initial studies was the suggestion that galaxy redshifts
take on preferred or 'quantized' values.
