It was just one of those things that happens. It wasn’t really anybody’s fault. The technology had been created decades ago and had simply been forgotten about as the cold war ended, the Berlin Wall fell, communism collapsed, and other world events unfolded.
It had been discovered completely by accident, back in the fifties when a scientist working in a government nuclear facility, hidden deep in a bunker in the middle of nowhere, had made a simple mistake with his calculations and there it was, in the middle of the room, the tiniest of holes in the fabric of spacetime. The trouble was, it didn’t stay tiny for very long, it grew exponentially, getting bigger very quickly. Luckily, the clever boffin realised exactly what he had created and managed to do something about it. He couldn’t fix it, or reverse what he had done to get rid of it. This was real life, not the movies, complicated sciency things just didn’t work that way.
However, what he did do, was create another one. This had the effect of sucking the first one into the second one but didn’t stop the second one from growing the same as the first, albeit a little slower as it digested the first one. So, he created a third to swallow the second and a fourth to swallow the third and so on and so forth until the growth of the hole was sufficiently slowed to give him an hour or two to devise a better solution. Which he did, a rather clever one in fact, he sealed the hole in a rather cleverly constructed quantum box. Far too complicated to explain in ten minutes, but suffice it to say, it was a very clever solution and it worked perfectly. The hole in the fabric of space time was contained and the whole of reality was saved from being sucked into it as it grew and grew.
What should he do with it now? The container itself needed containing, so he popped it in on a table in an unused room and put a sign on the door which simply read “DO NOT ENTER”. He wrote a report to his superiors on the whole incident and carried on with his work.
Over time the need for the facility waned, and it was eventually shut down, the bunker was forgotten about and after several decades, all that remained of its existence was a decaying slab of concrete hidden in the undergrowth of the woods that had grown around it, the buildings containing the hidden entrance having long since collapsed into rubble and pilfered away.
Eventually the slab collapsed, and a hole appeared, it was then discovered by a couple of boys playing in the woods. A hole in the floor with stairs leading down into the dark. The boys slowly descended the stairs, one of them sliding his hands along the damp wall for stability in the dark when his fingers inadvertently flicked a switch and the whole of the underground lair lit up, the decades old self-sustaining power system being still operational. Emboldened by the sudden illumination, the boys ventured on, eventually finding a door with a big “DO NOT ENTER” sign on the door. Surprisingly, the door was unlocked, and they ventured in, discovering a very odd-looking box on a table. One of them lifted the lid and peered inside, reached in and lifted out a strange wobbly ball. They played with it for a bit before leaving, promising each other they would come back tomorrow, taking the wobbly ball, which seemed a bit bigger than before, with them.
That night, in the bedroom of Robert Bobfrey, aged 12, of 10 Wilmington Avenue, and completely by mistake, the switch was made. The whole of spacetime collapsed in on itself, turning all of reality inside out as it did so. No one seemed to notice, even though everything was backward, they just carried on doing their thing the opposite way around in their newly created reverse reality. If only the scientist had locked the door.
