The Discordancy Report catalogs extragalactic discordant redshifts, critically analyzes the data and observations, and promotes continued scientific study of redshift discordance.

The Big Bang Theory is widely accepted today by both astronomers and astrophysicists alike.   However this theory into the origins of the Universe is based upon one very large assumption.

That assumption is that the shift in the observed light of most extragalactic objects toward the red end of the visible portion of the electromagnetic spectrum is caused by the accelerated expansion of the entire Universe. The Big Bang Theory postulates that this expansion began as a colossal explosion of all the matter and energy in existence today which started as an infinitesimal point of infinite heat and density almost 14 billion years ago.

But what happens to the Big Bang Theory if it is discovered that extragalactic redshifts are not caused by cosmic expansion and acceleration?

Modern astronomical observations clearly show that there are close and physically connected extragalactic objects with greatly differing redshifted spectra.  These varying spectra are assumed to indicate the objects are located and accelerating away at great distances and speeds from one another — not connected.

This website serves as a growing repository of these discordant redshift observations as well as an open forum for their analysis and discussion.  If redshifts are not indicative of distance or the expansion of the Universe then we are obligated as scientists and scientifically minded people to try to discover the source and origin of their intrinsic values.
