-
Conversely, to achieve a certain redshift in such a universe, the light has to travel a greater distance than it would in a uniformly expanding universe, in which case the supernova has to be farther away and therefore appear dimmer.

-
Whether this would explain all of the redshift is another matter, but it would seem to explain redshift as having other possible causes then only recession.
-
The advantages of this new method is that it goes to high redshift, that is, it looks at the expansion history of the Universe from 1. 7-6.3 in redshift.
-
It has a so-called redshift of 6.29, which translates to a distance of about 13 billion light-years from Earth.
