In this very entertaining but clearly scientifically profound speach, Sean Carroll confronts us with a new scenario regarding the origin of our Universe: The Big Bang wasn't the beginning.
"An unbroken egg is a low-entropy configuration, exactly like our universe at the Big Bang, and yet when we open our refrigerator we are not surprised to find this low-entropy configuration. That's because an egg is not a closed system: It comes out of a chicken. - Maybe the Universe comes out of an universal chicken?!"
