Measurements of the effects of the cosmic microwave background radiation in the dynamics of distant astrophysical systems in 2000 proved the Copernican principle on a cosmological scale.

Uniform cooling of the cosmic microwave background over billions of years is explainable only if the universe is experiencing a metric expansion.

Famous quotes containing the word confirmation:
“Trifles light as air
Are to the jealous confirmation strong
As proofs of holy writ.”
—William Shakespeare (1564–1616)
“Whenever reality reinforces a child’s fantasied dangers, the child will have more difficulty in overcoming them...So, while parents may not regard a spanking as a physical attack or an assault on a child’s body, the child may regard it as such, and experience it as a confirmation of his fears that grown-ups under certain circumstances can really hurt you.”
—Selma H. Fraiberg (20th century)
“The confirmation of Clarence Thomas, one of the most conservative voices to be added to the [Supreme] Court in recent memory, carries a sobering message for the African- American community.... As he begins to make his mark upon the lives of African Americans, we must acknowledge that his successful nomination is due in no small measure to the support he received from black Americans.”
—Kimberly Crenshaw (b. 1959)
