2001, New York
They returned to the archway and Forby wound the shutter down again.
‘So,’ said the man as he shouldered his assault rifle and cranked the handle. ‘What I don’t get is if this is still a version of the year 2001 how come those dino-humans out there aren’t a lot more advanced?’
Maddy and Sal looked at each other. ‘I dunno,’ said Maddy. ‘I’m no anthropologist.’
‘It’s a good question, Forby,’ said Cartwright. He turned round and crouched to get one last look out at the rainforest version of the Hudson River delta, and the far-off cluster of rounded huts on the muddy banks of Manhattan island. ‘A good question… and I’ll hazard a guess. They’re a dead-end branch of evolution.’
Forby looked at him. ‘Sir?’
‘Those things out there — ’ he flicked a finger out at the narrowing window of alternative world outside — ‘if they really are the direct descendants of some species that survived the end of the Cretaceous era, a species that somehow survived as a result of something that’s been changed — ’ he looked at the girls — ‘by your friend, then they’ve been around for tens of millions of years.’
‘Well, that’s exactly my point, sir. How come they aren’t light-years more advanced than humans? How come there isn’t some gigantic lizard version of Futurama out there?’ Forby finished cranking the shutter down. The archway was dim once more, lit by the sterile fizzing glow of the ceiling tube light.
‘They plateaued,’ said Cartwright. ‘Perhaps their species evolved to the best it could possibly be. And then just stopped.’
Sal made a face. ‘I thought evolution never stopped. I thought it always changed, always, like, adapting.’
‘Oh, but it does and can stop,’ he replied. ‘There are species alive today that are virtually identical to their distant prehistoric ancestors — sharks, for example. Nature had evolved them to be perfect for their environment, perfect killing machines… why bother adapting any further?’ He shrugged. ‘Perhaps in this world, those reptilian hominids out there are the dominant predator, with nothing to compete against… and have been that way for millions of years?
‘Evolution is nature’s way of problem solving. If something changes that challenges a species’ ability to survive, then that stimulates an adaptive response. If there’s nothing to challenge a species’ existence, then why would it ever need to change?’ Cartwright shrugged. ‘A dead-end of evolution.’
‘A dead-end world,’ echoed Forby.
They made their way across the dim archway. ‘On the other hand, maybe there’s some practical limit to how much smarter that species outside can get? Maybe those long heads are already too heavy to develop any greater cranial capacity?’
‘So their brains will never get any bigger?’
‘That’s right. And they’ll never do any better than spears, mud huts and dugout canoes.’
‘Well,’ said Maddy, approaching the desk, ‘whatever. We’ll never know, because those creepy-looking things weren’t meant to happen.’ She sat down at the computer desk. ‘Bob, how’re you doing with those candidate signals?’
› Analysis completed. The last 1,507 density soundings before you ordered me to cease the sweep indicated the immediate location was occupied by a permanent physical obstruction. This could be a natural intrusion, for example a fallen tree or a geological event.
‘So, before that?’ Maddy asked impatiently.
The others joined her at the desk.
› A total of 227 transient density warnings.
Cartwright squatted down beside her and studied the dialogue box. ‘That means what? So now you’re down to two hundred and twenty-seven possible locations for your friend?’
Maddy nodded. ‘Can we filter that any further?’
› Affirmative. 219 were single-incursion events. Of the remaining eight density signatures that demonstrated a repeated incursion, only one demonstrated a regularly timed signature.
Sal bit her lip with excitement. ‘That’s it! Surely? That’s got to be it!’
› Affirmative, Sal. There is a high probability that this is the correct time-stamp.
‘YES!’ said Maddy, spinning round in her chair, her hand raised for a high-five. Sal obliged with a hearty slap and a shriek of excitement.
Cartwright smiled. ‘I presume that means you’ve found your friend?’
‘Yes… see?’ Maddy grinned proudly. ‘I told you we could do it!’
‘So then… what happens now?’
She spun back to face the monitors in front of her. ‘Bob? We’re good to begin charging up to open a portal?’
› Information: we have a 24-hour time period identified in which to open a window.
‘Hmm.’ Maddy pulled absently on her top lip. ‘Twenty-four hours. But when exactly do we open it?’
Cartwright looked vexed and impatient.
‘We have to be sure they’re there, right?’ said Sal on Maddy’s behalf. ‘You know? Before we commit to opening a portal. If we spend the stored charge and they’re not there, we’ve gone and wasted it.’
Maddy nodded. ‘We’ll only have enough stored energy to open one, maybe two windows. How do we make sure they’re actually right there and ready and waiting to come through, though?’
‘Hang on!’ cut in Cartwright. ‘You just said “they”. Are you telling me there’s more than just your friend stuck back there?’
Sal nodded. ‘Yes, Liam… and some others… children that were caught up in an accident.’
‘Good God,’ the old man whispered. ‘Accident? This was an accident? What the heck have you people been up to?’
‘It was a training incident,’ cut in Sal, ‘that’s all. It went wrong. These things happen from time to time.’
› Information: it will be possible to open a series of pinhole windows and obtain a small-resolution image of the target location.
‘Right.’ Maddy nodded. ‘Right… then we could see exactly when — during the day — there’s somebody standing around. Yes… yes, good idea, Bob. Let’s proceed with that.’
› Affirmative.
Cartwright sighed. ‘So what’s happening now?’ Clearly impatient to see the displacement machine actually finally running.
Maddy turned to look over her shoulder. ‘We’re taking some images of the portal location to make sure that when we open the window they’re ready and waiting to come through.’
‘Why don’t you just open your portal and see for yourself?’
‘Sal just explained that. We could be wasting a full power-up, and we can’t risk doing that.’ Maddy shrugged. ‘Anyway, wouldn’t you want to check first? This is the Cretaceous era, right? That means dinosaurs. I’d want to know the coast is clear of T-rexes first. Don’t you?’
The old man glanced at Forby and the man shook his head quickly. ‘Taking a few photos first sounds like a pretty good move to me, sir.’
Cartwright laughed nervously. ‘Uh, I guess you’re right. OK… we’ll do it your way. Just get a move on before those hunters down the beach find a railway arch in the middle of their jungle.’
