Answer

Brief Explanations:

The cosmic - microwave background radiation, which is a uniform background radiation detected in every direction, is one of the key pieces of evidence for the Big - Bang theory. It is thought to be 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 galaxies spinning faster than expected based on visible matter is evidence for dark matter.

Answer:

Uniform background radiation is detected in every direction.
