Why the Universe Is Our Home: It’s Not a Coincidence (Part 2)

Deepak-chopraAt the human level everyone would like to feel that life has meaning, which implies that the setting for life — the universe at large — isn’t a cold void ruled by random chance.  There is a huge gap here, and for the past century science hasn’t budged from its grandest assumption, that creation is ruled by random events. There was good reason for this adamant position. The mathematics of modern physics is a marvel of precision and accuracy.  No guiding hand, creator, higher intelligence or deity was needed as long as the equations worked.

Now there is a crack in the theory, tiny at first but opening into a fissure, that casts doubt on how science observes the universe. The fault isn’t that the mathematics was wobbly and loose. Quite the opposite.  The universe is too finely tuned to fit the random model.  God isn’t going to leap into the breach, although religion has reason to feel better about not accepting the so-called “accidental universe.”  The real fascination lies in how to match reality “out there” with the potentiality of the human mind.  Both are up for grabs.

In the modern era, Sir Arthur Eddington and especially Paul Dirac first noticed that certain “coincidences” in dimensionless ratios can be found. These ratios link microscopic with macroscopic quantities. For example, the ratio of the electric force to gravitational force (presumably a constant), is a large number (about 1040), while the ratio of the observable size of the universe (which is presumably changing) to the size of an elementary particle is also a large number, surprisingly close to the first number (also about 1040).   It is hard to imagine that two very large and unrelated numbers would turn out to be so close to each other.  Why are they? (For earlier examples of fine tuning, please see our first post, which gives some general background as well.)

Dirac argued that these fundamental numbers must be related. The essential problem is that the size of the universe is changing as the cosmos expands, while the first relationship is presumably constant, given that it involves only two supposed “constants.” Why should two very large numbers, one variable and the other not variable, be so close to each other?  (It’s like seeing a person’s vocal chords vibrating in all kinds of ways and yet discovering that each word he speaks is exactly half a second apart — even this image is a simplification compared to the actual problem, which spans similar ratios in terms of light years and time in the trillionth of a second.)

Why the Universe Is Our Home: It’s Not a Coincidence

It would be reassuring to most people to discover that the universe is constructed to favor life.  If the human race isn’t a freakish outcome of highly improbable chance events, we have every right to see the universe as our home. But this psychological reassurance strikes physicists and biologists as wishful thinking; the bulwark of modern science, from the most minuscule events at the quantum scale to the Big Bang itself, is the assumption that creation is random, without guidance, plan, mind or purpose.

Only very slowly has such a blanket view been challenged, but these new challenges are among the most exciting possibilities in science. We’d like to outline the argument for a “human universe” with an eye to understanding why the human race exists. This question is too central to be left to a small cadre of professional cosmologists and evolutionary biologists; everyone has a personal stake in it.

The most accepted theory of the large-scale structure of the universe is Big Bang cosmology, which has achieved impressive results. Yet when you try to model the universe, you can’t escape the problems surrounding what seems like a simple act: observing it.  Measuring the cosmos is intricately interwoven with limits imposed by the process of observation itself. As you go back in time or ahead into the future, as you reach so far into space that light takes billions of years to reach Earth,  any possible model encounters horizons of knowledge at some ultimate, faint observational limit. Beyond such a horizon, observation is blocked, and so are physics, mathematics and the human mind.

For example, with the Big Bang theory, light cannot be used to observe further back in time or across immense distances to arrive close to the very beginning itself. The first instant of the Big Bang remains forever hidden from the present. Knowledge about the early universe has to be inferred. We can examine the parts that scattered after the Big Bang, but we cannot grasp the whole. Thus, our observational limitations prohibit verifying cosmological theories to any degree of accuracy for any observational test. So the Hubble telescope, marvelous as it is for sending back photos of distant galaxies, can’t reveal reality independent of cosmological theory.  Theory cannot be verified with complete certainty, which means that important topics like the expansion of the universe and the evolution of galaxies are our own mental constructs; they reflect who we are as observers, not independent reality.
