Answer

Brief Explanations:

The cosmic - microwave background radiation, which is a form of uniform background radiation detected in every direction, is one of the key pieces of evidence for the Big - Bang theory. It is considered the "afterglow" of the Big Bang. Planetesimals forming in debris disks is related to planet formation, most galaxies are moving away (not toward us) according to Hubble's law, and the faster - than - expected galaxy spin is related to dark matter.

Answer:

Uniform background radiation is detected in every direction.
