The telescope, in enabling us to look far out into space, also allows us to look back in time. Light travels at about 186,000 miles per second. When we look up into the daylight sky, we are not seeing the sun as it currently is but as it was about eight minutes ago, since it takes that long for the light radiating from this familiar star to travel 93 million miles to Earth. Similarly, when the Giant Magellan Telescope (GMT) receives light waves from the depths of the universe, those waves will have originated from points as far as 76 sextillion (76,000,000,000,000,000,000,000) miles away. It will have taken those waves some 13 billion years to arrive on earth, meaning they left their source about a million years after the big bang, and roughly nine to ten billion years before Earth even formed.

Quantum fluctuations are, at their root, completely a-causal, in the sense that cause and effect and ordering of events in time is not a part of how these fluctuations work. Because of this, there seem not to be any correlations built into these kinds of fluctuations because 'law' as we understand the term requires some kind of cause-and-effect structure to pre-exist. Quantum fluctuations can precede physical law, but it seems that the converse is not true. So in the big bang, the establishment of 'law' came after the event itself, but of course even the concept of time and causality may not have been quite the same back then as they are now.

The Hartle-Hawking derivation of the unconditional probability of the existence of a universe of our sort is inconsistent with classical theism. The unconditional probability is very high, near to 1. For purposes of simplification, we are saying the probability is 99 percent; there is a 99 percent probability that a universe of our sort__ will call it a Hartle-Hawking universe__xists uncaused.The universe exists uncaused since the probability amplitude is determined by a summation or path integral over all possible histories of a finite universe. That is, the probability that a Hartle-Hawking universe exists follows directly from the natural-mathematical properties of possible finite universes; there is no need for a cause, probabilistic or otherwise, for there to be a 99 percent probability that a Hartle-Hawking universe will exist.This is not consistent with classical theism. According to classical theism, if a universe is to have any probability of existing, this probability is dependent on God's dispositions, beliefs, or choices. But the Hartle-Hawking probability is not dependent on any supernatural states or acts; Hartle and Hawking do not sum over anything supernatural in their path integral derivation of the probability amplitude.Furthermore, according to classical theism, the probability that a universe exist without divine causation is 0, and the probability that if a universe exists, it is divinely caused, is 1. Thus, the probabilities that are implied by classical theism are inconsistent with the probabilities implied by the Hartle-Hawking wave function of the universe.

The biblical account of the origin of the cosmos in Genesis, for example, posits that a god created the physical universe particularly with human beings in mind, and so unsurprisingly placed the Earth at the center of creation.Modern cosmological knowledge has refuted such an account. We are living in the golden age of cosmology: More has been discovered about the large-scale structure and history of the visible cosmos in the last 20 years than in the whole of prior human history. We now have precise knowledge of the distribution of galaxies and know that ours is nowhere near the center of the universe, just as we know that our planetary system has no privileged place among the billions of such systems in our galaxy and that Earth is not even at the center of our planetary system. We also know that the Big Bang, the beginning of our universe, occurred about 13.7 billion years ago, whereas Earth didn__ even exist until about 10 billion years

The ultimate singularity is the Big Bang, which physicists believe was responsible for the birth of the universe. We are asked by science to believe that the entire universe sprang from nothingness, at a single point and for no discernible reason. This notion is the limit case for credulity. In other words, if you can believe this, you can believe anything. It is a notion that is, in fact, utterly absurd, yet terribly important. Those so-called rational assumptions flow from this initial impossible situation. Western religion has its own singularity in the form of the apocalypse, an event placed not at the beginning of the universe but at its end. This seems a more logical position than that of science. If singularities exist at all it seems easier to suppose that they might arise out of an ancient and highly complexified cosmos, such as our own, than out of a featureless and dimensionless mega-void.

With my limited understanding what I think happened was that God decided to play a fun game. He created a great experiment and BANG and Kapoof! He exploded into millions of trillions of little pieces and they are each one of them us, scattered all over the universe. This would mean that we are all pieces of each other. We all belong to each other. I am part of you, you are part of me, always have been, always will be. If you put us all together, well, maybe that is God.
