Reading from "God and the Big Bang", by Daniel C. Matt, Jewish Light Publishing, Woodstock, Vermont p. 71:

As members of the cosmos, we derive from the big bang. Every quark within each of us was present at the beginning, not figuratively or metaphorically, but actually. The universe is still reverberating from the big bang, as evidenced by cosmic micro-wave background radiation, which has been coursing through space for fifteen billion years. Our highly developed mind may be able to perceive the origin of the universe. Through science, the deductive mind observes and gropes its way back as far as possible and as close as possible to the beginning of time and space. Through contemplation, the meditative mind observes and gropes its way back. The two approaches, while not the same, are complementary paths from our limited, human van-tage point to the beginning.
Why does the scientific approach work? Granted that much remains unknown, how is it that we can piece things together to the extent that we can? As Einstein wondered, "The most incomprehensible thing about the universe is that it is compre-hensible." Because the evolution of our brains followed the workings of natural law, they resonate with the organization of the natural world. We, too, emerged from the cosmic order, so our cognitive capabilities reflect that order. As children of the cosmos, we not only explore the nature of our universe, but glimpse its laws.

David Simons in a blue dress shirt In Genesis, God gives man and woman dominion over the rest of creation. This is a pernicious notion that has lead to a lack of human appreciation for the balance of nature and a self-destructive arrogance in dealing with the rest of creation. Our modern scientific story of creation presents a very different picture of humanities place in the cosmos. In this version humankind appears on the scene so very late in the time span of the world as to be a veritable flash in the pan, an afterthought in the long span of creation.

This is a serious lesson and a warning to be heeded. The Universe is 13.7 billion years old. Life on Earth has existed for 3.7 billion years. Human beings have been around for about 200,000 years. Earth and its life have done fine without us and probably can do just fine without us again if we insist on making it impossible for the biosphere to sustain us. This should be cautionary and humbling. While I tell you this, I still do wonder if our ability to contemplate the awesomeness of creation is really just a chance accident of the creative process or something more significant. Our understanding of natural history tells us that we are but a passing blink in the vastness of Creation. None the less the more we learn of creation, the more it appears to be pregnant with the possibility of life and, perhaps, even self-aware life.

We do share a oneness. Everything is made up of the same collection of matter, all created simultaneously during the Big Bang. Most everything is stardust fused in the furnace of stars and perhaps deeply connected through the fabric of space-time, a fabric that still holds greatest mysteries. With this can we not say that intelligent life might just be a manifestation of the Universe striving toward self-awareness. This is a mystical idea and one that I would be very hard pressed to defend logically in the context of my understanding of existence. Evolutionary science tells us that there is no direction to evolution other than achieving the fitness for a set of environmental conditions, conditions that change in the blink geologic time. Still, once intelligence appears it does afford great evolutionary advantage particularly when combined with social cohesion. These advantages also carry the seeds of our destruction. I believe that part of the great cosmic experiment is to find out if so called "intelligent life" is intelligent enough to stop sowing its own destruction. If we survive, then we might somehow become like cells in the great brain of universal self-consciousness. Even though I have not the slightest notion how that might come to pass, this mystical conception does appeals to me and I believe that our survival as a species does depend on a significant portion of humanity buying into the modern creation story and demonstrating a species capacity for rational understanding of our world.

Our emerging creation story draws from all of science including general relativity, particle physics, astronomy, chemistry, biology and geology. This story draws on the best science humankind can muster today and should be the creation story we all tell our children. I would like to discuss how the birth of the scientific method has lead to our current understanding of creation and why there should be and really is magic and wonder in this story. Since even a much attenuated version of the story has filled many books my version here is necessarily very sparse.

One of the simplest push backs of biblical fundamentalist to scientific claims concerning the age of the Earth and the Universe as well as the composition and age of life on Earth is the question " if you weren't there how could you possibly know what happened". The simple answer is we have learned these truths through the application of the scientific method and the scientific method has been demonstrated over the past 300 years to be the best way to ascertain truths about the workings of the physical world. This is a good answer while also a statement of a worldview. Those of us that have been educated to that worldview do accept it as gospel. I would claim that I have been educated in this worldview and not indoctrinated to it. That is in itself is a topic for deeper exploration.

As a professional scientist I have spent my life trying to understand and ferret out various facets of nature through this process we call the scientific method which involves detailed observations and recordings of natural phenomena that are then codified and integrated through comparison with a logical construct we call theory. In much of science, theory is often realized in the form of algebraic equations. It is always so in physics. A large part of scientific work involves finding or creating the right equations. To me it still seems rather mysterious that we humans, as products of this creation, can formulate a representation of nature that is so good that solving equations broadens our understanding of nature. Really, do think about this! How is it that nature is understandable and quantifiable and at all predictable by this method? Why should it or how can it be that algebra and calculus, allow a logical description of nature and permit us in many cases to even extend our understanding into predicting the future or ferreting out the past?

Through calculus we can describe the trajectory of a comet predicting its location tomorrow. We can place a satellite in orbit around the earth using Newton's laws of motion as realized in an algebraic form. Through simple algebra derived from quantum theory we look at the light emitted from sunspots and deduce the strength and direction of the magnetic field in the surface of the sun or look at distant stars and deduce the atmospheric composition from analyzing the emission spectra. How wonderful and mysterious it is that this cosmos is quantifiable.

Did human beings invent mathematics or did they discover it? Does the Universe do mathematics? Most scientific investigation is carried out with the belief that a quantifiable description of natural processes can be determined. The quantifiable and predictable nature of physical processes is so embedded in our understanding of science that we assume that poor predictions result from a poor understanding of the science not a fallacy in the scientific method. We call meteorology an imprecise science because it doesn't predict tomorrow's weather exactly. We assume as we understand the weather better we will get better and better at predicting future weather. And to a certain extent that is justified by past performance because with computer models and satellite data meteorologist do a lot better today than they did do twenty years ago.

This notion that science can create predictive understanding of nature is not that old an idea. It is pretty much the result of the success of Isaac Newton in the 17th century in formulating the laws of motion and the theory of gravity. Newton's achievement was well recognized in his own time. A little ditty by Alexander Pope tells it all, "Nature's Laws lay hid in night; God said, Let Newton be! And all was light." Newton changed humanities understanding of nature and is credited with bringing the clockwork Universe into human awareness.

Newton published the Principia Mathematica, his most important theoretical work in 1686. Some of you may have heard the famous story of Edmond Halley coming to Newton at Cambridge College where Newton was a lecturer in mathematics and asking Newton what the shape of the orbit of the planets might be and Newton telling him that it was an ellipse. Halley asked Newton for an explanation. Newton promised to send Halley his notes because he couldn't find them. Two years later the first book of the Principia arrived on Halley's desk at the Royal Society in London.

What had Newton done? He had taken Kepler's rules of planetary motion that were based on Tycho Brahe's measurements and formulated a theory of motion and gravity which he then turned into algebraic equations. He then invented calculus to solve those equations and demonstrated that he could quantitatively reproduce Kepler's Laws of planetary motion and precisely demonstrate the orbits of celestial bodies. He could then precisely predict the future return of Halley's Comet and explain the geometric form of the planetary orbits. This is a revolution in human thinking. The mysteries of nature had become accessible to the human mind through observations of nature and the formulation of quantifiable algebraic expressions.

1686 is a little over 300 years ago. How the world has changed as a result of this insight. As we see from Pope's ditty, people were enthralled and some probably aghast at the time that the Universe could be understood and described in this manner. Newton's discovery - or perhaps invention - made it possible to use mathematics to understand the world in a very different way. Over the 300 hundred years since their publication people have extended his laws and mathematics to constructing buildings, bridges, dams and roads. They have reshaped his equations to understand the dynamics of earth, water and air, and even learned to fly. And believing as he taught us, that nature could be described by equations, developed an understanding of electricity and magnetism bringing us radios, Television and all manner of electromechanical devices. Prior to Newton the physical world at least in western culture was animated by the ever-present mind of God. In the Greco-Roman and Germanic worlds, nature was permeated with Gods who were the actuators and controllers of the natural world. The wind, the air, the sea, the sun, and the moon all had deities who were the forces of nature and all could be responsive to the supplication of humans.

When the monotheistic god of the Jews replaced the Greco-Roman pantheon, that one God simply replaced all the others as the ever present actuator. Newton, without meaning too, turned this on its head. He showed humanity that God had created the Universe with governing laws and principals so that the system could run completely on its own. God could have started the creation with a set of rules and walked away only to peak in once in awhile to see what had come about as a result of this particular set of rules. This idea gained acceptance pretty quickly because people were very much accustomed to thinking of God as the law and rule-giver. After all Moses came down from Mount Sinai with a set of Laws. That was what God did. He made Laws and rules and Isaac Newton showed us that God's rules could be discovered by use of the scientific method and a well- prescribed application of reason.

In Newton's case that logical process was tightly embedded in an algebraic structure. He created equations that represented the rules and then he needed only solve those equations to discover just what nature was up to. The strict rules of the algebra force a logical progression of thinking that produced the conclusions. One of the great powers of this methodology is that it produces results and predictions that are not obvious in the original formulation of the equations. In the 1860's the Scottish physicist Clerk Maxwell working with the experimental data and mathematical ideas developed by Michael Faraday and Andre-Marie Ampere, used calculus to formulate a set of eight equations to describe electric and magnetic fields. In solving his equations he discovered that they predicted a wave in space that traveled at the speed of light. What he had discovered from the equations was that light was a wave formed by propagating electric and magnetic fields.

The equations also predicted the existence of the here-to-for unknown electromagnetic spectrum, which included radio waves. As a result of these mathematical predictions Heinrich Hertz succeeded in producing radio waves in1878 and demonstrating that they traveled at the speed of light verifying Maxwell's predictions. People were reaching into the mind of God to see how the Universe had been created. Would we have ever discovered radio waves without those equations? I don't think so!!

Algebra is only one way of performing logic and certainly I don't want to claim that it is the only forms of logic used in the sciences. Some processes are still too complex to capture in equations. With the advent of computers there are many trying to make everything numerically predictable. I mention this because there are aspects of the Theory of Evolution that have been captured in mathematical expressions but most of it is based on rules with prediction ascertained through logic. It is this aspect of Darwin's theory that makes this theory easier to attack than purely mathematical formulations.

It is through the scientific method, first justified by Isaac Newton and reinforced through the next 200 years by people like Maxwell, that we peer far into the past and far into the future. Our most distant looks at the past and our understanding of the age of the Universe comes to us by interpreting astronomical data through the lens of the General Theory of Relativity which is an extension of Newton's Theory of Gravity by Albert Einstein. Our understanding of the progression of life on Earth comes through two centuries of paleontology, geology and biology as focused through the lens of Darwin's Theory of Evolution. As we study the formation of our sister planets Mars and Venus and look closely at the moons of Jupiter through the relatively new science of planetology we have gained great insights into the long history of Earth's atmosphere and the chemical, physical and biological processes that have shaped it over its 4.5 billion years of existence.

The Theory that most shapes are current view of the Universe outside our solar system is the Theory of General Relativity. Its most revolutionary prediction is that energy and mass effect the motion of objects not by exerting a force on them as Newton described but by warping the very space around objects. It was Einstein's intention to reformulate the Theory of Gravity in a manner consistent with the relativity principal which had revealed that space was four dimensional with time being the fourth dimension. This leads to the conclusion that the presence of mass and energy in space shapes the very fabric of space and causes it to expand or shrink depending upon how much mass and energy there is in the Universe. These predictions were logical conclusion that emerged from the equations rather than something Einstein knowingly built into them. And because through astronomical observations we have discovered that the Universe is expanding we now understand that it has a finite extent and long ago must have been much smaller than it is today. This certainly competes as the most revolutionary prediction of 20th century physics. These predictions often run counter to our intuition but as we have studied the stars and galaxies through light, radio waves and gamma rays and as we learned more about atoms and their nuclei, as well as quantum theory the predictions of the Theory of General Relativity are consistent with what we see.

Using the scientific method a story of creation has emerged. In a most abbreviated form it tells us that 13.7 billion years ago the Universe came into existence as a tiny spot smaller than an atom. It contained all matter, energy and space within its tiny self. We know of nothing outside it. It took a few minutes to expand sufficiently for the nuclei of hydrogen and helium to coalesce, it took 379, 000 years for atoms to form, and the first star did not light until over 100 million years. These first giant stars burned out in a billion or so year as they converted hydrogen and helium into the heavier elements. They collapsed on themselves going supernova and filling the universe with all the rest of the elements.

Some eight billions years after the Big Bang about two third of the way out from the center of the galaxy we call the Milky Way gravity collapsed this new combination of primordial hydrogen, helium and the heavier elements from the star dust to form our sun and its eight planets. The four inner planets started to coalesce primarily from tiny planetesmals created by the heavier elements bumping into each other to form larger and larger rocks that were densely scattered around the new sun. By 4.5 billion years ago the planet Earth while still pelted by large and small space rocks began to cool enough to form a planetary crust. The largely molten interior spewed out hot gases through the thin crust to create the early atmosphere of methane, nitrogen, ammonia, carbon dioxide, and water vapor.

By 3.5 billion years ago the early seas were already hosting the first prokaryotic life forms, which with the development of photosynthesis were starting the process of releasing oxygen from water to change the atmosphere. The prokaryotic life held sway over the earth for the next 1.6 billion years bringing us to 1.9 billion years ago when small colonies of prokaryotes got together to form the first one celled eukaryotes. These one celled Eukaryotes shared the earth with the prokaryotes for the next 1.3 billion years until 570 millions year ago the first multi-cellular Eukaryotes appeared in the Precambrian seas. Over the next 30 million years all of the basics ancestral life forms came into existence. Through the next 150 million years this multi-cellular life added new creatures filling many niches in the sea from trilobites to jellyfish to sharks. By 380 million years ago the vertebrate tetra pods in the form of amphibians along with plants had moved on to the earth's land. Early mammals and dinosaurs appeared around 230 million years ago. The dinosaurs dominated the land, sea and air for the next 165 million years. 65 million years ago a giant meteor struck the earth causing the cretaceous-tertiary mass extinction which paved the way for the rise of mammals as the dominant land animal form on earth. Just 6 million years ago the first hominid ancestor of humans appeared. Homo sapiens, our own species finally arrived on the scene about 195, 000 years ago.

It is an amazing property of our Universe that some of its deepest mysteries are accessible to human understanding through equations that are created according to the rules of the scientific method. Applying the scientific method appropriately, we humans have developed a procedure through mathematical representation that can encompass a vast reach of nature far beyond the initial questions and insights of any particular scientist formulating the theories. I believe this property of nature or maybe more appropriately this great gift of creation is itself the greatest of miracles. The reading I chose gave a rational for this ability of human intelligence to understand nature through our reason. It is an evolutionary argument.

In the process of organisms developing that were appropriately suited to their environment, predictability and the ability to take advantage of predictability created our form of intelligence. That intelligence is therefore characteristic of the universe and in consonance with it and naturally adapted to create a predictive system suited to that universe. As I have pointed out we humans only stumbled on to this understanding a little over three hundred years ago. That understanding has made it possible to majorly change our relationship to and understanding of nature.

As we understand today, through application of the scientific method, our kind has existed on this earth for about 200,000 years. Yet in only 300 years, 1/500th of human existence, we have utterly changed how a significant proportion of humanity lives. We have tripled life expectancy, greatly reduced the impact of disease, and have eliminated for many humans hunger and famine, a scourge of existence which dominated human experience over much of the preceding 1,500 centuries. And that has happened in only 3 centuries. If we can manage to survive as a worldwide civilization over the next century through a concerted application of the scientific method we might actually make it through another million years. Of course there is still some significant portion of human kind that does not appreciate the power of reason and its child, the scientific method. And if we cannot get them educated to the lessons it brings, our civilization may not make it into the next century.
