You may have noticed recently, if you’ve been reading
popular science magazines, that scientists are going increasingly
mad.
What is the source of their madness? That the advance of science
over the last half century points ever more clearly to the
inescapable conclusion that the universe had a beginning,
and second, that the universe is fine-tuned in the very finest
detail for life, specifically life on Earth. The first is
concluded from Big Bang cosmology, the second from the discovery
of a multitude of instances of cosmic fine-tuning that scientists
call “anthropic coincidences” (anthropic from
the Greek anthropos, human being).
In short, the cosmic landscape looks frighteningly familiar—a
sudden creation out of nothing, but one that is governed by
intricate laws, precisely balanced forces, and a delicate
interplay of matter and energy that culminates in the appearance
of human beings.
It is this frightening familiarity that apparently maddens
(at least some) scientists. As a recent article (2/2004) in
the popular science magazine Discover remarks, “many
astrophysicists are still uncomfortable with the implication
that the Big Bang marked the beginning of time itself.”
An even greater cause for discomfort, is that the advent of
a beginning implies the necessity of an outside cause: “What
made the Big Bang go bang?”
In short, it appears that Big Bang cosmology is driving science
to theological conclusions. In the oft-quoted words of astronomer
Robert Jastrow, the mysterious abruptness of the universe’s
beginning means that “science will never be able to
raise the curtain on the mystery of creation. For the scientist
who has lived by his faith in the power of reason, the story
ends like a bad dream. He has scaled the mountains of ignorance;
he is about to conquer the highest peak; as he pulls himself
over the final rock, he is greeted by a band of theologians
who have been sitting there for centuries.”
Add on top of that, that the “bang” was unimaginably,
ingeniously fine-tuned, down to the smallest detail, and the
discomfort level rises even further. As astronomer Fred Hoyle
famously stated, “a commonsense interpretation of the
facts suggests that a super intellect has monkeyed with physics,
as well as chemistry and biology, and that there are no blind
forces worth speaking about in nature.”
For scientists who refuse to follow the flow of cosmological
evidence, the only way out of embracing this reality, so it
seems, is to chase after insanity and throw themselves into
the arms of cosmological madness.
Witness the following from the above-mentioned article in
Discover entitled “Before the Big Bang.”
It describes the theoretical work of a pair of “maverick”
cosmologists, Paul Steinhardt and Neil Turok, who “have
a radical idea that could wipe away these mysteries.”
How do they propose to tear away the “curtain on the
mystery of creation”?
By spinning a cosmology out of wholly imaginative cloth, a
cosmology that cannot be tested because it is conveniently
tucked away where it can provide no evidence. They assert
(according to the author of the article, Michael Lemonick)
that “the cosmos was never compacted into a single point”
as the Big Bang implies. Rather, “the universe as we
know it is a small cross section of a much grander universe
whose true magnitude is hidden in dimensions we cannot perceive.”
As the reader suspects, it is rather difficult to test a theory
that depends on evidence “hidden in dimensions we cannot
perceive.” Such dimensions do, however, provide a good
intellectual hiding place for those scientists uncomfortable
with the theological implications of the Big Bang.
But there’s more. “What we think of as the Big
Bang,” argue the pair, “was the result of a collision
between our three-dimensional world and another three-dimensional
world less than the width of a proton away from ours—right
next to us, and yet displaced in a way that renders it invisible.”
We needn’t be bothered by the Big Bang because “the
Big Bang is just the latest in a cycle of cosmic collisions
stretching infinitely into the past and into the future. Each
collision creates the universe anew.” Thus, we escape
from the confines of a worrisome beginning, into a beginning-less,
endless cycle of eternal cosmic collisions. Steinhardt and
Turok call this “the ekpyrotic universe,” from
the Greek for “conflagration,” a name that “refers
to an ancient Stoic cosmological model in which the universe
is caught in an eternal cycle of fiery birth, cooling, and
rebirth.”
Ekpyroticism solves another problem. Since our universe is
just one of a multitude of universes, we needn’t be
worried that it appears so finely-tuned that it leads one
to the conclusion that “a super intellect has monkeyed
with physics.” In an endless cycle of cosmic collisions
of an infinite number of universes at least one or two of
the universes, by chance alone, would turn out with the right
combinations of fundamental forces, energy, matter, and so
on. We happened to have won the cosmic lottery, so to speak.
The evidence for all of this? Again, there isn’t any.
The most one could say is that Steinhardt and Turok are tracing
out one possible mathematical skein spun from superstring
theory, a horrifyingly complex mathematical web in theoretical
physics that attempts to bind together matter, energy, space-time,
and the basic forces of nature into one unified tapestry.
But a mathematical theory is only illuminating if it fits
neatly upon reality, and sheds light upon actual evidence.
Alas, the maverick theory of Steinhardt and Turok fails on
both counts. Their theory does not fit upon reality, but only
upon realms “we cannot perceive.” And furthermore,
their theory of endless cosmic collisions of infinite universes
is not grounded in any evidence. Rather, the aim of the theory
is simply to do away with the embarrassing evidence of the
Big Bang.
Theoretical mathematical models often lead to great advances
in science. In fact, the Big Bang theory was the result of
following out the implications of the mathematical equations,
known as the field equations, in Albert Einstein’s general
theory of relativity. But mathematics leads to madness when
it is used to lay aside reality and sweep aside evidence.
Such madness may avoid theological conclusions, but only at
the expense of destroying science.
And so, the mystery of the universe’s abrupt beginning
remains, despite the attempts of some scientists to avoid
it. What is truly mysterious, is that it wasn’t a band
of theologians that scientists met on top of the mountain,
but even stranger, a tribe of ragtag nomadic Semitic sheepherders
who had been there, not merely a few centuries, but for several
millennia. |
