As galaxies move away from our galaxy a shift on the electromagnetic spectrum (EMS) is noticed. This phenomena is called:

• redshift

• blueshift

• unshift

• blackshift

How does Cosmic Microwave Background Radiation (CMBR) support the Big Band Theory?

• Residual energy in the form of microwaves are found everywhere in the universe.

• Microwaves were created at the time of the Big Bang and are still found today.

• Microwaves are useful in our everyday lives

• Microwaves are collected from space to be used in microwave ovens.
