No Such Thing As Eternity?

Physicist says thought no longer possible someday

Here’s my book review of Until the End of Time by astrophysicist Brian Greene. Until now, I thought eternity was a thing.

If there’s no superintelligence to think, how could it start over?

It’s the best survey of current theories in cosmology that I’ve read. But it’s also the most unsettling to someone like me who tries continually to reconcile science and theology.

Fans of my Evan Wycliff Mystery series know that Evan is similarly conflicted. A farm boy from southern Missouri from a devout Baptist family, he thought he’d go into the ministry. But then he studied at Harvard Divinity, where learning more about the history of Christianity and its hypocrisies shook his faith. Then, seeking answers to the big questions instead in science, he enrolled in postgrad astrophysics at MIT. He dropped out of that program, too. Discouraged and heartbroken for other personal reasons, Evan returned to farmland roots, where he got occasional work as a guest preacher and a credit investigator for the local car dealer.

Evan is a preacher who some days is an agnostic. And he’s an amateur sleuth because he has investigative skills. People in his community come to him with problems that no one else has any interest in solving.

So – no surprise – from the standpoint of intellectual curiosity, Evan and I are a lot alike.

Two conclusions in Greene’s book would startle us both. First, there can be no such thing as eternity. The universe is about 14 billion years old and has more than double that time before it expires. But, according to Greene, expire it will – expanding and disintegrating into cosmic dust, then expanding more until particles are so far apart they can’t form any solid mass – no galaxies, no stars, no planets.

Now, from the viewpoint of the philosopher or mystic, eternity is not simply a long, long time. Or even a timeline that has no end. It’s a state of being. Time-less – an incomprehensible notion for the human mind.

But more disturbing still is Greene’s assertion that – long before the universe expires – thought itself won’t be possible. Thought in humans is biochemically supported electrical activity in the brain. When the cosmos becomes diffuse, no such complex structures will exist.

Now, unaddressed in Greene’s survey is the question of whether consciousness and thought are aspects of the same physical process. Some scientists, including Christoph Koch, have tried to explain consciousness as super-complex electrical activity in the brain. Koch has found no such explanation. He theorizes that computers, no matter how complex, can never be conscious. In his book The Feeling of Life Itself, at the conclusion he can only guess that consciousness is some as yet unmeasurable, fundamental property of the universe, a feeling shared by all living things, in various degrees depending on the complexity of their brains. For rigorous scientist Koch, it’s little more than a guess.

Where is God in all this? Our religious traditions hold that God is pervasive consciousness and eternal. Another hypothesis of Greene and his colleagues is the so-called godless universe. That is, the dual processes of entropy (diffusion) and evolution (ever-increasing complexity) are sufficient to explain everything that exists.

Which brings us to the most elusive question of all, one that philosophers have debated for centuries, which also has the scientists stumped:

Why is there something rather than nothing?
