For almost one hundred years, we have known that the universe is expanding. We have traced this expansion back in time, through to the very beginning when the universe occupied an infinitesimal point in space. This was the state of the universe at time t=0, over 13 billion years ago.

It is from this starting point that everything we are familiar with came into existence: protons, neutrons, stars, galaxies - even space and time itself are here. At time t=0, this point began an unprecedented inflation, in this instant time and space were born. This event has become known as the Big Bang.

The big bang is our current, most accepted theory for how the universe began. It was inspired by the discovery that the universe is expanding.

It was an unusual and highly counterintuitive event. It was not an explosion, it did not occur inside anything, rather, everything that we are familiar with: left, right, up, down, cause and effect, the stage for all physical laws, was getting larger.

We possess a natural curiosity of the world around us. We want to know how and why things are the way they are.

This curiousity has served us well because it carries significant survival benefits. If we see an event and ask ourselves why it happened or what caused it, we are more likely to spot a threat before it becomes dangerous in the future.

Our curiosity gives us the ability to look beyond the present moment. From it, we have evolved an urge to look for causes, it is an inseparable part of our biology. Because of this, we really can't help ourselves when we attempt to find a cause for creation, it is second nature for us to ask, 'What Caused the Big Bang?'

Any answer to this problem must begin with a key realization: both time and space are contained within the universe and came into existence only AFTER the Big Bang occurred. The cause of the universe must not include them, they are not available to us. It must come from outside our experience.

In this realm, the...
