The Multiverse may not remove the need for a Personal Creator
Scientists agree that the universe was in a hot dense period approximately 13.8 billion years ago. Everything we have observed from the Cosmic Microwave Background (CMB) to the expansion of the universe to the distribution of light elements supports this hypothesis. The Big Bang was one of the most spectacular discoveries of the 20th century, blindsiding many scientists who had concluded that the universe was static and eternal.
Its original formulation, however, used Einstein’s theory to show that, if the universe is of equal density everywhere and has no biases in any particular direction, then from its expansion we can work backward to an infinitely dense singularity from which all matter and energy emerged.
This idea quickly runs into problems, however. The CMB is too highly correlated with itself. The universe is also remarkably flat spatially. What explains this flatness?
Inflationary theory was developed to explain these problems. The idea is that the universe before it was full of matter and radiation was full of inflationary energy. This energy caused it to inflate up until some point where that energy spontaneously converted into matter and radiation, leading to the structures we see in the universe today.
