Laplace's Demon
an excerpt

When I come into school the next day, Xanthe’s eyes are all red and puffy. As I think about it, I know the answer why. But she tells us the minute she sees me and Leanne stroll through the main gates.
“I broke up with Rick!” It’s insane, they break up at least every month, sometimes twice. But she still expects us to offer us the same amount of sympathy. Xanthe looks at me. “But I guess you already knew that,” she says bitterly. I shake my head.
“Nah, it’s not like I get BBC news alerts or anything.” I say. “I have to think about something really specific, like last night I would have had to have thought ‘What is Xanthe doing right now?’ to know that you were breaking up.” Leanne turns to look at me.
“It’s really real isn’t it?” she says softly. She’s never really believed in it, even though she couldn’t come up with any sort of argument explaining an alternative theory as to how I seemingly knew everything.
“Yes.” I say, and Leanne shakes her head.
“This is crazy.” She says. “Impossible, improbable. You can’t just know everything, it goes against all laws of science.” Leanne is our resident scientist. But she’s wrong. “You can’t just have that knowledge, your brain would therefore need more neurones connected than there are atoms in the universe!”
“Unless…” Olivia says slowly, I hadn’t even noticed her arrive at school. I wonder how long she’s been standing there. “It’s just one neuron that means she can access the collective knowledge of the world.”
“But it goes beyond that.” I say, feeling the need to stand up for myself. I’ve been testing it, like I can see the future, and everything that happened in the past. Give me any time, and date, and I can tell you what every single person in the world at the time was doing at that point.
“Right, what was I doing at eight in the morning on the sixteenth of September, 1990?” Olivia says jumping straight in. I think about it for a minute, it’s not a good image.
“Being born?” I say slowly. Olivia laughs. “Eww, why did you make me think of that?”
“Amusement factor.” She says as the bell goes.
