Goodbye Shroud

The face from the Shroud of Turin

The face from the Shroud of Turin

Some years ago, I researched and wrote a piece for Christian History Institute in which I brought out a number of facts which suggested the Shroud of Turin was a hoax. Holy Shroud, Mysterious Relic.) These included contemporary statements, radio-carbon testing, pigmentation errors, and misleading reports on the shroud’s pollen content. A couple shroud believers wrote me angry emails.

My skeptical approach was right. Luigi Garlaschelli, an Italian professor of inorganic chemistry, has reproduced the shroud, using only methods available in the 13th-century. Carbon dating tests had established that century as the most probable era for its creation.

Garlaschelli was not the first to produce such an image. In Spring, 1982 Skeptical Inquirer also printed pictures of images reproduced using 13th-century techniques.

Book Review: A Step Farther Out

Pournelles ever-timely essays

Pournelle's ever-timely essays

Jerry Pournelle’s essays, A Step Farther Out, were published as a book in 1979—thirty years ago. A bit late for a review, you say? Do you belong to a procrastinators club? No and no. My justification for reviewing this “old” book is two-fold. One, I just ran across it; and two, the themes of its opening essays are so timely they could have been written for today.

Now I am going to confess that I have read only the first third of the book. The remaining essays may turn out to be dogs (although I doubt it), but the opening essays are electrifying.

In “Survival with Style” and “A Blueprint for Survival” Pournelle points out the doomsday mentality of American intellectuals and the danger of losing our nerve. He shows that our problems are soluble if we think big and allow innovation.

I was especially interested in his defiance of the Club of Rome’s doom-and-gloom. Not only are those guys wrong on almost every testable count, but their solutions point directly to the ten-headed dragon-state of Revelation. Pournelle saw straight through them.

Unfortunately, we seem to be taking the path Pournelle begged us to avoid: we lost our nerve. We are following the nay-sayers of the Club of Rome. Pournelle was calling us to faith—faith that with clear thinking, big dreams and hard work we could triumph over our obstacles. As a Christian I see those virtues springing from trust in God (which is why intellectuals by and large have no vision; they have jettisoned God).

Not many looks at social issues hold up so well as Pournelle’s. I rather think every such book ought to be reviewed in thirty years. We’d see then who were our Wormtongues and who talked straight.

Real Science Fiction

Science fiction afficionadoes, imagine harnassing stars and moving them from place to place. Or contemplate living on a planet where everyone pays one another in good deeds. Think what it would be like to meet aliens for the first time, or to live for eons upon eons. How wonderful it would be to terraform a world! Or suppose you could set your foot into the fabric of space and “feel” your way into another dimension. Think of the implications of a time machine which permits you to examine the past and answer historical questions. What if the great figures of yesteryear could be brought together in one place and you could meet them? What if you could live forever?

For many years I was an avid reader of science fiction. From Balmer’s When Worlds Collide to Philip Jose Farmer’s Riverworld I read fascinating speculations and longed to enter the authors’ worlds. As I grew in my Christian faith, however, science fiction began to turn me off because of its increasing trend toward hubris, occult, pornography and atheism. It was no longer the delight it had been.

However, all was not lost. Fulfillment of all the desires evoked in me by science fiction is promised in God’s word.

Jesus was able to pass through walls. Clearly he moved through other dimensions. We are to have a body like his with the same ability.

To us angels are aliens. We will meet them.

And we will meet every person ever saved by the blood of Christ. Imagine what histories of God’s dealings with men we will learn! Mathematics shows us that we can spend an infinite amount of time with every person in heaven even if we see each person only once every billion or trillion or quintillion years, because an infinite series (such as prime numbers), no matter how far separated or how sporadic, remains an infinite series.

It appears we will terraform worlds. Paul teaches us that all creation groans until the Sons of God are revealed. Evidently at that time we are going to fix some broken things.

In heaven it seems we will pay our way in love and praise.

And there will be ages upon ages of new experiences (the Hebrew for “forever” is “ages of ages.”) Paul speaks of “ages to come.” Apparently God has planned many different learning levels, each encompassing an age, until at last everything is put in God and God is all and in all. Then the inventor of everything, the creator of the longings which find dim expression in science fiction, will be our eternal delight.

What promises these are! No wonder Jesus compared the kingdom to a pearl of great price which we ought to sell everything to obtain. “Make every effort to enter the kingdom of heaven,” he said. No wonder those barred from the kingdom will go with weeping and wailing.

Lord, let us put nothing in this ephemeral world above gaining that kingdom.

Artificial Intelligence and the Eye

The marvellous human eye.

The marvelous human eye.

Artificial means something created by human art rather than occurring in nature. Artificial intelligence (AI) is a computer program designed by humans to handle problems creatively, that is in the manner that the higher animals or humans would handle them.

An enormous amount of brainwork goes into successful AI developments. And the most efficient solutions generally come from the study of nature. For example, Boston College researchers Hao Jiang and Stella X. Yu recently revealed an improved method for getting computers to recognize moving objects.

Not surprisingly, their method more closely imitates the working of the human eye and brain than previous methods had.

When the most intelligent minds in our labs find it necessary to model their hardware and program designs on nature’s designs (and still can only roughly approximate nature’s successful designs), one is compelled to consider the overwhelming likelihood that nature itself has an intelligent designer of far superior ability.

Fewer Hiding Places

Fake column swings open to admit priest to hidden stairwell at the Partingdale house.

Those trying to evade capture had an easier time of it in the past than they will in the future. For example, Corrie Ten Boom hid Jews in the German-occupied Netherlands for many months. Even when she was arrested, the Jews she was shielding were not, secure in their hiding place. Similarly, authorities in England could hunt over a mansion for days without discovering priests in their priest holes.

Today, technology threatens to eliminate the chance of escaping a persecuting government. Devices that can detect heart beats are in common use by border agents. Had the Germans had those when they ransacked Corrie’s house, the game would have been up for the Jews.

A new robotic ferret is being designed at the University of Sheffield to detect hidden drugs, weapons and illegal immigrants. Designed to crawl across the ceilings in freight containers, it detects minute quantities of illegal substances and can hear muffled heart beats. A 21st-century Scarlet Pimpernel will find it harder to use such containers to deliver persecuted minorities from bloodthirsty mobs.

The Last Question

A Univac computer at the Census Bureau.

The most wicked show I ever saw was not in a theatre or on TV. It was at a planetarium. Highly touted in the press, the presentation was Isaac Asimov’s short story “The Last Question.”

The question, asked of a colossal computer named Multivac, was whether or not entropy could be reversed (and life continue). Multivac answered, “INSUFFICIENT DATA FOR MEANINGFUL ANSWER.”

Over trillions of years mankind fills not only our home galaxy but all the galaxies of the universe. Future generations ask the question again and again of Multivac’s successors which have more and more intelligence. Before the last man fuses with Multivac which has now become Cosmic-AC, he asks the question again and AC replies, “THERE IS AS YET INSUFFICIENT DATA FOR A MEANINGFUL ANSWER.”

The story ends this way:

The consciousness of AC encompassed all of what had once been a Universe and brooded over what was now Chaos. Step by step, it must be done.

And AC said, “LET THERE BE LIGHT!”

And there was light –

Humans have a tendency to make gods of created things and of what their hands have made. This tendency is aptly illustrated in Asimov’s story and in reader’s/viewer’s reactions to it. Despite gross scientific inaccuracies,* the story receives raves across the web. Readers revel in its blasphemy. One declared “I have found a new religion.” Some acknowledge that seeing this show led them to embrace atheism.

In “The Thinking Machine,” an Asimov essay which corresponds to this story, he declared that the only difference between a computer and the human brain is complexity. Evidently he also believes that the only difference between God the Creator and a computer is an even higher level of complexity. In his “wisdom,” he reached the pantheistic religious position that the totality of the universe itself is god.

I consider “The Last Question” the most wicked show I’ve seen because it directly, willfully defies the first and second commandments, “You shall have no other gods before me,” and “you shall not make for yourself an idol.” Fancy throwing away faith on untenable hypotheses such as hyperspace and the non-existence of spirit.


*For example, Asimov declares all galaxies are the same and inhabitable; they are not; and at the rate they are stretching apart many will not even be visible from ours on a time scale far shorter than his story encompasses.

God’s Recorders

With camera phones and other technology, privacy is fast becoming a thing of the past.

With camera phones and other technology, privacy is fast becoming a thing of the past.

What is the one thing you have done in secret that you would be most ashamed to find splashed across the internet?

Just one hundred years ago, such a question would have been meaningless. Today, with cameras in watches and cellphones, private remarks and momentary indiscretions caught on video or voice recorder, flash around the world instantaneously.

If, in less than a hundred years, we have come so far in our ability to recover what is said and done, think what a civilization 1,000 years in advance of us might be able to do. It could well be that in such a civilization no word, or deed could escape investigation. For all we know, the inhabitants of such a civilization may have learned to extract subtle imprints from the very brick of houses or the stones in the fields.

In point of fact, we have good reason to believe that an infinitely advanced civilization exists. Whoever designed the universe and its life had immense technical skill and finesse.

As a Christian, I believe that designer was God. I believe also that he issued the following warning against hypocrisy: “There is nothing concealed that will not be disclosed or hidden that will not be made known. What you have said in the dark will be heard in the daylight, and what you have whispered in the ear in the inner rooms will be proclaimed from the roofs” (Luke 12:1-3).

When I think of this warning, I tremble. Believing that God has infinitely advanced recording capabilities, I have sought to live my life as an open book; and yet I know I have gossiped, expressed half-truths, misjudged peoples’ motives aloud and stumbled in other ways that I wish could remain permanently hidden. They won’t be—although God promises me that at some point my record will be permanently expunged and He will remember my sins no more.

But what about hypocrites who lie, cheat, impose on others and deliberately do wrong while cunningly pretending it is all for good? God’s hidden recorders are taping them now and the recordings will be played on the day of judgment.

False Miracles

The Bible tells us that at the end of this age a deceiver will come working false miracles and drawing virtually the whole world after him. Some theologians take false miracles to mean actual miracles worked by Satan as opposed to miracles worked by God. I suspect that, at least some of the time,  false means fake.

Throughout history, there have been plenty of charlatans willing to fake supernatural powers to gull spiritual followers. From Egyptian priests operating hidden levers and siphons to monks coaxing tears from statues of Mary to Uri Geller bending spoons there have always been fakirs willing to trade on the credulity of human kind. 

Two of the miracles ascribed to the deceiver are the ability to cause an image to speak and the power to call fire from heaven. Neither seems altogether out of the range of modern technology. The right person willing to use illusion and some of the more arcane findings of quantum physics and numerology could have a hey-day. Imagine how many people would follow a fakir with the skill of illusionist David Copperfield. 

Science fiction writers have toyed with the idea of impressing a backward people with “supernatural” technology.  Mark Twain pioneered the theme in his hilarious A Connecticut Yankee. Another amusing story with this theme is David Gerrold and Larry Niven’s The Flying Sorcerers. It is not a safe idea to seriously fantasize; the destiny of the deceiver (and his followers) will be to suffer eternally in the Lake of Fire.
