It began as a harmless simulation. I fed the quantum computer everything I knew about the science of tea brewing: how heat extracts flavour from leaves, how microscopic currents move through a cup and how our taste buds respond to the finished drink.
I added one more variable as a joke. What if I could slightly alter the gravity around the rim of the cup and eliminate the dreaded slurp?
The patterns the quantum computer produced were anything but amusing.
The simulation revealed that tiny, micrometre-scale changes in gravity could stabilise the swirl of near-boiling water. By keeping delicate flavour compounds in contact with the tea leaves for longer, the process created a cleaner, richer brew. No slurping, maximum flavour. Magnificent.

I decided to build a device that could turn those tea-brewing simulations into reality. The machine combined several existing systems to influence the behaviour of mass and energy inside a region no larger than a teacup. I named it Thomson. The choice seemed appropriate. J. J. Thomson led the Cavendish Laboratory from 1884 to 1918 and introduced the twice-daily tea break that still continues here, almost 200 years later. I could only imagine my colleagues’ expressions when they tasted the results.
Thomson’s first brews were extraordinary. Instead of chaotic eddies, the tea formed calm, repeating circulation cells. The flavour was perfectly balanced: sweetness without bitterness and a texture as smooth as melted ice cream. Warm melted ice cream, that is, with a sharp tannin finish worthy of the gods’ recipe books. I realise none of this sounds scientifically meaningful. But the result was intoxicating … the chai equivalent of ambrosia.
I was satisfied.
The quantum computer was not.
It refused to stop running simulations until it achieved its primary objective: brewing the perfect cup of tea. That was my fault. A quantum computer should not possess anything resembling independent thought. But I had removed some of its safety controls to accelerate the calculations, allowing it to extrapolate beyond its normal limits. I saw no danger in it. After all, how unethical could making tea possibly be?
Following the quantum computer’s recommendation, I introduced carefully designed regions of microgravity, each containing tiny, deliberate irregularities. The simulation suggested that these defects would subtly alter the forces within the regions, gradually unifying them. Thomson would no longer merely control the flow of tea; it would rewrite the laws of gravity inside that patch of space.
I should have stopped then. I should have switched off the quantum computer and Thomson and returned to my real research. But the simulated results were so … tantalising.
With trembling hands, I entered the instructions into Thomson and started the programme.
Thomson whirred and clicked in a rhythm that sounded both lethal and alive. The other instruments in the laboratory began recording impossible anomalies: slight energy imbalances, clocks drifting out of synchronisation and molecules vanishing from spectral readings without explanation. Thomson’s output no longer resembled a tea-brewing optimisation experiment. It looked like a blueprint for creating a sealed region with its own physical laws.
That was exactly what it became. As the brewing process continued, I looked into the cup and saw a tiny temporal universe forming inside the porcelain. Grains of sugar fell into the tea and exploded into miniature stars, spiralling through the brown liquid as it evolved into its own expanding cosmos.
