Everyone will knowEveryone will know: that theoretically our universe : that theoretically our universe started as one point of energystarted as one point of energy
Most people will be able to explainMost people will be able to explain: the different parts : the different parts of the Big Bang Theory, and why the theme song from the of the Big Bang Theory, and why the theme song from the
TV makes senseTV makes sense
Some people will be able to explainSome people will be able to explain: the Doppler : the Doppler Effect and Hubble’s theory and why it is evidence for the Effect and Hubble’s theory and why it is evidence for the

theories on the creation of the universetheories on the creation of the universe
Theories are not Laws (fact), they are not proven 100%, Theories are not Laws (fact), they are not proven 100%, but they do have a lot of evidence to back them upbut they do have a lot of evidence to back them up
