Clare found him in the empty car park, pacing out the dimensions of Petra’s Great Temple. He looked at her when she repeated his name, shook his head, slightly disoriented.
“This is the Central Arch, with the Theatron,” he explained. “East and West corridors.” He gestured. “In the center, the Forecourt, beyond the Proneos, and then the great space of the Lower Temenos.”
“And all this,” she said, looking faintly interested, “is a kind of imaginal reconstruction of Petra.”
“Of its Temple, yes.”
“The rose-red city half as old as time?” Now a mocking note had entered her voice.
He took her roughly by the arm, drew her into the shade of the five-story brick and concrete structure where neuropharmaceutical researchers had formerly plied their arcane trade. “Clare, we don’t understand time. Look at this wall.” He smote it with one clenched fist. “Why didn’t it collapse when the Moon was removed? Why didn’t terrible earthquakes split the ground open? The earth used to flex every day with lunar tides, Clare. There should have been convulsions as it compensated for the changed stresses. Did they see to that as well?”
“The dinosaurs, you mean?” She sighed, adopted a patient expression.
Blackett stared. “The what?”
“Oh.” Today she was wearing deep red culottes and a green silk shirt, with a bandit’s scarf holding back her heavy hair. Dark adaptive-optic sunglasses hid her eyes. “The professor hasn’t told you his latest theory? I’m relieved to hear it. It isn’t healthy for you two to spend so much time together, Robert. Folie à deux is harder to budge than a simple defensive delusion.”
“You’ve been talking to Kafele Massri?” He was incredulous. “The man refuses to allow women into his house.”
“I know. We talk through the bedroom window. I bring him soup for lunch.”
“Good god.”
“He assures me that the dinosaurs turned the planet Venus upside down sixty-five million years ago. They were intelligent. Not all of them, of course.”
“No, you’ve misunderstood—”
“Probably. I must admit I wasn’t listening very carefully. I’m far more interested in the emotional undercurrents.”
“You would be. Oh, damn, damn.”
“What’s a Temenos?”
Blackett felt a momentary bubble of excitement. “At Petra, it was a beautiful sacred enclosure with hexagonal flooring, and three colonnades topped by sculptures of elephants’ heads. Water was carried throughout the temple by channels, you see—” He started pacing off the plan of the Temple again, convinced that this was the key to his return to Venus. Clare walked beside him, humming very softly.

“I understand you’ve been talking to my patient.” Blackett took care to allow no trace of censure to color his words.
“Ha! It would be extremely uncivil, Robert. To drink her soup while maintaining. A surly silence. Incidentally, she maintains. You are her. Client.”
“A harmless variant on the transference, Massri. But you understand that I can’t discuss my patients, so I’m afraid we’ll have to drop that topic immediately.” He frowned at the Egyptian, who sipped tea from a half-filled mug. “I can say that Clare has a very garbled notion of your thinking about Venus.”
“She’s a delightful young woman, but doesn’t. Seem to pay close attention to much. Beyond her wardrobe. Ah well. But Robert, I had to tell somebody. You didn’t seem especially responsive. The other night.”
Blackett settled back with his own mug of black coffee, already cooling. He knew he should stop drinking caffeine; it made him jittery. “You know I’m uncomfortable with anything that smacks of so-called ‘Intelligent Design.’ ”
“Put your mind at. Rest, my boy. The design is plainly intelligent. Profoundly so, but. There’s nothing supernatural in it. To the contrary.”
“Still—dinosaurs? The dog I was talking to the other day favors what it called a ‘singularity excursion.’ In my view, six of one, half a dozen—”
“But don’t you see?” The obese bibliophile struggled to heave his great mass up against the wall, hauling a pillow with him. “Both are wings. Of the same argument.”
“Ah.” Blackett put down his mug, wanting to escape the musty room with its miasma of cranky desperation. “Not just dinosaurs, transcendental dinosaurs.”
Unruffled, Massri pursed his lips. “Probably. In effect.” His breathing seemed rather improved. Perhaps his exchanges with an attractive young woman, even through the half-open window, braced his spirits.
“You have evidence and impeccable logic for this argument, I imagine?”
“Naturally. Has it ever occurred to you. How extremely improbable it is. That the west coast of Africa. Would fit so snugly against. The east coast of South America?”
“I see your argument. Those continents were once joined, then broke apart. Plate tectonics drifted them thousands of miles apart. It’s obvious to the naked eye, but nobody believed it for centuries.”
The Egyptian nodded, evidently pleased with his apt student. “And how improbable is it that. The Moon’s apparent diameter varies from 29 degrees 23 minutes to 33 degrees 29 minutes. Apogee to perigee. While the sun’s apparent diameter varies. From 31 degrees 36 minutes to 32 degrees 3 minutes.”
The effort of this exposition plainly exhausted the old man; he sank back against his unpleasant pillows.
“So we got total solar eclipses by the Moon where one just covered the other. A coincidence, nothing more.”
“Really? And what of this equivalence? The Moon rotated every 27.32 days. The sun’s sidereal rotation. Allowing for current in the surface. Is 25.38 days.”
Blackett felt as if ants were crawling under his skin. He forced patience upon himself.
“Not all that close, Massri. What, some . . . eight percent difference?”
“Seven. But Robert, the Moon’s rotation has been slowing as it drifts away from Earth, because it is tidally locked. Was. Can you guess when the lunar day equaled the solar day?”
“Kafele, what are you going to tell me? 4 BC? 622AD?”
“Neither Christ’s birth nor Mohammed’s Hegira. Robert, near as I can calculate it, 65.5 million years ago.”
Blackett sat back, genuinely shocked, all his assurance draining away. The Cretaceous-Tertiary boundary. The Chicxulub impact event that exterminated the dinosaurs. He struggled his way back to reason. Clare had not been mistaken, not about that.
“This is just . . . absurd, my friend. The slack in those numbers . . . But what if they are right? So?”
The old man hauled himself up by brute force, dragged his legs over the side of the bed. “I have to take care of business,” he said. “Leave the room, please, Robert.”
From the hall, where he paced in agitation, Blackett heard a torrent of urine splashing into one of the jugs he had emptied when he arrived. Night music, he thought, forcing a grin. That’s what James Joyce had called it. No, wait, that wasn’t it—Chamber music. But the argument banged against his brain. And so what? Nothing could be dismissed out of hand. The damned Moon had been picked up and moved, and given a vast deep carbon dioxide atmosphere, presumably hosed over from the old Venus through some higher dimension. Humanity had been relocated to the cleaned-up version of Venus, a world with a breathable atmosphere and oceans filled with strange but edible fish. How could anything be ruled out as preposterous, however ungainly or grotesque?
“You can come back in now.” There were thumps and thuds.
Instead, Blackett went back to the kitchen and made a new pot of coffee. He carried two mugs into the bedroom.
“Have I frightened you, my boy?”
“Everything frightens me these days, Professor Massri. You’re about to tell me that you’ve found a monolith in the back garden, along with the discarded cans and the mangy cats.”
The Egyptian laughed, phlegm shaking his chest. “Almost. Almost. The Moon is now on orbit a bit over. A mill
ion kilometers from Venus. Also retrograde. Exactly the same distance Ganymede. Used to be from Jupiter.”
“Well, okay, hardly a coincidence. And Ganymede is in the Moon’s old orbit.”
For a moment, Massri was silent. His face was drawn. He put down his coffee with a shaking hand.
“No. Ganymede orbits Venus some 434,000 kilometers out. According to the last data I could find before. The net went down for good.’
“Farther out than the Moon used to orbit Earth. And?”
“The Sun, from Venus, as you once told me. Looks brighter and larger. In fact, it subtends about forty minutes of arc. And by the most convenient and. Interesting coincidence. Ganymede now just exactly looks . . . ”
“ . . . the same size as the Sun, from the surface of Venus.” Ice ran down Blackett’s back. “So it blocks the Sun exactly at total eclipse. That’s what you’re telling me?”
“Except for the corona, and bursts of solar flares. As the Moon used to do here.” Massri sent him a glare almost baleful in its intensity. “And you think that’s just a matter of chance? Do you think so, Dr. Blackett?”
10.
The thunderstorm on the previous day had left the air cooler. Blackett walked home slowly in the darkness, holding the HP calculator and two books the old man had perforce drawn upon for data, now the internet was expired. He did not recall having carried these particular volumes across the street from the empty library. Perhaps Clare or one of the other infrequent visitors had fetched them.
The stars hung clean and clear through the heavy branches extending from the gardens of most of the large houses in the neighborhood and across the old sidewalk. In the newer, outlying parts of the city, the nouveaux riches had considered it a mark of potent prosperity to run their well-watered lawns to the very verge of the roadway, never walking anywhere, driving to visit neighbors three doors distant. He wondered how they were managing on Venus. Perhaps the ratio of fit to obese and terminally inactive had improved, under the whip of necessity. Too late for poor Kafele, he thought, and made a mental note to stockpile another batch of pioglitazone, the old man’s diabetes drug, when next he made a foray into a pharmacy.
He sat for half an hour in the silence of the large kitchen, scratching down data points and recalculating the professor’s estimates. It was apparent that Massri thought the accepted extinction date of the great reptiles, coinciding as it did with the perfect overlap of the greater and lesser lights in the heavens, was no such thing—that it was, in fact, a time-stamp for Creation. The notion chilled Blackett’s blood. Might the world, after all (fashionable speculation!), be no more than a virtual simulation? A calculational contrivance on a colossal scale? But not truly colossal, perhaps no more than a billion lines of code and a prodigiously accurate physics engine. Nothing else so easily explained the wholesale revision of the inner solar system. The idea did not appeal; it stank in Blackett’s nostrils. Thus I refute, he thought again, and tapped a calculator key sharply. But that was a feeble refutation; one might as well, in a lucid dream, deny that any reality existed, forgetting the ground state or brute physical substrate needed to sustain the dream.
The numbers made no sense. He ran the calculations again. It was true that Ganymede’s new orbit placed the former Jovian moon in just the right place, from time to time, to occult the sun’s disk precisely. That was a disturbing datum. The dinosaur element was far less convincing. According to the authors of these astronomy books, Earth had started out, after the tremendous shock of the X-body impact that birthed the Moon, with an dizzying 5.5 or perhaps eight-hour day. It seemed impossibly swift, but the hugely larger gas giant Jupiter, Ganymede’s former primary, turned completely around in just 10 hours.
The blazing young Earth spun like a mad top, its almost fatal impact wound subsiding, sucked away into subduction zones created by the impact itself. Venus—the old Venus, at least—lacked tectonic plates; the crust was resurfaced at half billion year intervals, as the boiling magma burst up through the rigid rocks, but not enough to carry down and away the appalling mass of carbon dioxide that had crushed the surface with a hundred times the pressure of Earth’s oxygen-nitrogen atmosphere. Now, though, the renovated planet had a breathable atmosphere. Just add air and water, Blackett thought. Presumably the crust crept slowly over the face of the world, sucked down and spat back up over glacial epochs. But the numbers—
The Moon had been receding from Earth at a sluggish rate of 38 kilometers every million years—one part in 10,000 of its final orbital distance, before its removal to Venus. Kepler’s Third Law, Blackett noted, established the orbital equivalence of time squared with distance cubed. So those 65.5 million years ago, when the great saurians were slain by a falling star, Luna had been only 2500 km closer to the Earth. But to match the sun’s sidereal rotation exactly, the Moon needed to be more than 18,000 km nearer. That was the case no more recently than 485 million years ago.
Massri’s dinosaur fantasy was off by a factor of at least 7.4.
Then how had the Egyptian reached his numerological conclusion? And where did all this lead? Nowhere useful that Blackett could see.
It was all sheer wishful thinking. Kafele Massri was as delusional as Clare, his thought processes utterly unsound. Blackett groaned and put his head on the table. Perhaps, he had to admit, his own reflections were no more reliable.
11.
“I’m flying down to the coast for a swim,” Blackett told Clare. “There’s room in the plane.”
“A long way to go for a dip.”
“A change of scenery,” he said. “Bring your bathing suit if you like. I never bother, myself.”
She gave him a long, cool look. “A nude beach? All right. I’ll bring some lunch.”
They drove together to the small airfield to one side of the industrial park in a serviceable SUV he found abandoned outside a 7-Eleven. Clare had averted her eyes as he hot-wired the engine. She wore sensible hiking boots, dark gray shorts, a white wife-beater that showed off her small breasts to advantage. Seated and strapped in, she laid her broad-brimmed straw hat on her knees. Blackett was mildly concerned by the slowly deteriorating condition of the plane. It had not been serviced in many months. He felt confident, though, that it would carry him where he needed to go, and back again.
During the ninety-minute flight, he tried to explain the Egyptian’s reasoning. The young psychiatrist responded with indifference that became palpable anxiety. Her hands tightened on the seat belt cinched at her waist. Blackett abandoned his efforts.
As they landed at Matagorda Island, she regained her animation. “Oh, look at those lovely biplanes! A shame they’re in such deplorable condition. Why would anyone leave them out in the open weather like that?” She insisted on crossing to the sagging Stearmans for a closer look. Were those tears in her eyes?
Laden with towels and a basket of food, drink, paper plates and two glasses, Blackett summoned her sharply. “Come along, Clare, we’ll miss the good waves if we loiter.” If she heard bitter irony in his tone, she gave no sign of it. A gust of wind carried away his own boater, and she dashed after it, brought it back, jammed it rakishly on his balding head. “Thank you. I should tie the damned thing on with a leather thong, like the cowboys used to do, and cinch it with a . . . a . . . ”
“A woggle,” she said, unexpectedly.
It made Blackett laugh out loud. “Good god, woman! Wherever did you get a word like that?”
“My brother was a boy scout,” she said.
They crossed the unkempt grass, made their way with some difficulty down to the shoreline. Blue ocean stretched south, almost flat, sparkling in the cloudless light. Blackett set down his burden, stripped his clothing efficiently, strode into the water. The salt stung his nostrils and eyes. He swam strongly out toward Mexico, thinking of the laughable scene in the movie Gattaca. He turned back, and saw Clare’s head bobbing, sun-bleached hair plastered against her well-shaped scalp.
They lay side by side in the sun, odors o
f sun-block hanging on the unmoving air. After a time, Blackett saw the red setter approaching from the seaward side. The animal sat on its haunches, mouth open and tongue lolling, saying nothing.
“Hello, Sporky,” Blackett said. “Beach patrol duties?”
“Howdy, doc. Saw the Cessna coming in. Who’s the babe?”
“This is Dr. Clare Laing. She’s a psychiatrist, so show some respect.”
Light glistened on her nearly naked body, reflected from sweat and a scattering of mica clinging to her torso. She turned her head away, affected to be sleeping. No, not sleeping. He realized that her attention was now fixed on a rusty bicycle wheel half buried in the sand. It seemed she might be trying to work out the absolute essence of the relationship between them, with the rim and broken spokes of this piece of sea drift serving as some kind of spinal metaphor.
Respectful of her privacy, Blackett sat up and began explaining to the dog the bibliophile’s absurd miscalculation. Sporky interrupted his halting exposition.
“You’re saying the angular width of the sun, then and now, is about 32 arc minutes.”
“Yes, 0.00925 radians.”
“And the Moon last matched this some 485 million years ago.”
“No, no. Well, it was a slightly better match than it is now, but that’s not Massri’s point.”
