What is the term used to describe the universe's expansion that is equal in all directions?

• Peculiar motion

• Hubble flow

• Dark flow

• Galactic drift

What is the cosmic microwave background (CMB) primarily used for in cosmology?

• Identifying black holes

• Calculating the speed of light

• Galactic drift

• Cosmic shift

What is a key requirement for Feynman diagrams to be valid?
