The Commuter Coefficient

Patricia Ng calculated the probability of arriving at work on time: 67.3%. This was up from last month’s 54.8%, owing to the Metro Authority’s decision to reduce compression ratios in the rush hour carriages from 1:50 to 1:35.

“Less efficient,” her fellow commuters grumbled, “but fewer instances of passengers arriving at their destination before they’d left.”

The Central Line Compression Tube hummed at regulation 13.7 gigahertz as Patricia entered. Inside, three hundred commuters occupied a space designed for fifty. The compression field made this possible by folding space along its least resistant axis - which, unfortunately, was often through the passengers themselves.

“Stand clear of the dimensional doors,” the announcement warbled, its voice compressed and decompressed so many times it sounded like mathematics given speech.

Patricia gripped the probability rail - a handrail that existed in several states simultaneously to accommodate compressed passengers. Her hand overlapped with seventeen others, all occupying the same space at different phase angles. The sensation was like holding hands with ghosts who were also trying not to vomit.

The train lurched into motion. Or rather, space lurched around the stationary train. Compression transit worked by folding the universe rather than moving through it, which was energy-efficient but played havoc with inner ears evolved for linear travel.

“Next stop: Quantum Gardens. Please gather all probable belongings.”

Patricia watched her fellow passengers flicker as the compression field fluctuated. A businessman existed as a smear of probability across three seats. A student was compressed so tightly she appeared two-dimensional from certain angles. An elderly woman had partially decompressed, her left arm arriving at destinations several seconds before the rest of her.

The real problem wasn’t the technology - it was the biology. Human consciousness could adapt to compression, but the body rebelled. Motion sickness became probability sickness. Jetlag became existence lag. The lucky ones just got headaches. The unlucky ones arrived at work to find parts of themselves still commuting.

“I’ve been taking the compressed metro for five years,” the man next to Patricia said. Or rather, his mouth said it. His voice arrived three seconds later from somewhere near the ceiling. “You get used to the dissociation.”

Patricia doubted that. Her company had started offering “compression leave” - sick days for employees whose consciousness had become unstuck from their physical location. Last week, Roberts from Accounting had attended a meeting while his body was still on the train. He’d made excellent points about quarterly projections, speaking from thin air while his meat-self dozed against a window twenty miles away.

The train folded through another dimensional junction. Patricia’s stomach stayed behind briefly, then snapped back like elastic. Around her, commuters checked their phones, read newspapers, pretended this was normal. The human capacity for adaptation was remarkable.

“Arriving at Tower Complex. Mind the gap between dimensions.”

Patricia exited, feeling the familiar relief as her particles agreed to exist in one location again. She checked her watch: 8:47 AM. She checked her phone: 9:15 AM. She checked the station clock: Yesterday.

Temporal shear from compression transit. IT would sort it out, probably. They had a whole department dedicated to synchronizing employees who’d arrived at different rates.

67.3% on time. In a world where “time” and “on” had become negotiable concepts, that was almost impressive.
