Shaun was yet another physicist, working for yet another western country on yet another doomsday machine. Even that being far from the last world war, governments still had excuses to spend exorbitant amounts of money on secret projects that would never be used, just for the sake of the argument. It never matters what you do in war, but what’s the size of your gun, compared to the rest, and in that, his country was second to none. Not that anybody cared any more, or that anybody knew of that, since his country has never gone into a proper war in its history, but well, with these things, you can never be to sure, can you.
But I digress, Shaun, yes, the physicist. He had been working on his own project for nearly a decade now and had re-used the old pieces of the LHC in a much more miniaturized version, of course, but in essence, it was capable of creating elementary particles and at the same time entangle them. After the initial explosion, instead of losing the created particles into oblivion (what would be the point in entangling them in the first place, uh?), he actually converged the entangled particles back into atomic form. The idea was to create a clone army, or sub-atomic bombs, or whatever could be done to put fear in other countries. You know how scientists are attached to science-fiction, and Shaun was no exception.
In the beginning he wasn’t very successful, and it took him nearly 5 years to produce a pair of atoms with their quarks and gluons entangled on the other side. While you could easily make atoms entangle in normal lab conditions using lasers, at the moment you turned your machines off, they would go back into their natural state. But in this case, the effects were much more lasting. In recent years, he managed to create whole molecules that were virtually the same, stable for months, even years. Copy cats.
But what he didn’t expect (who would) was that his experiments were also touching the adjacent m-branes of parallel universes. It was hypothesised in the past that some forces could leak to adjacent universes, like gravity, and though that wasn’t widely accepted, it was very hard to prove it wrong. The problem is, until today, nobody had reached energy densities so intense as to actually make a remarkable effect on the parallel universes. Shaun did.
If the parallel universe was, like ours, sparsely populated, with a only handful of pseudo-sapient species, he’d probably have hit empty space. But the universe he found was nothing ordinary. In fact, Shaun’s own experiments for years had created a special condition, in which the aforementioned universe became aware of our own. I explain. His experiments, the entanglement of particles not always worked, as I said earlier, and the less they worked (ie. less matter on this universe), the more they leaked into the adjacent universe.
A door to your own room
In a lovely evening of spring, such as today, with daffodils and tulips blossoming, and the warm spells finally arriving, Shaun would normally be working. 30 storeys below ground. He would see none of that, or care for that matter. His new molecules (DNAs this time) were working at an alarming rate. He managed to duplicate an entire gene last week, and his team was now running loads of tests on the results. It required a lot of energy to create molecules enough to run all tests, but his lab had unlimited supply of everything.
With all his team elsewhere, Shaun was busy trying to expand his technique to achieve the whole sequence of a virus. That made the machine run at wild energy levels (quite a few Pev), and the whole thing destabilized for a moment, and stopped. Fearing he made the surrounding city go dark, he checked all energy inputs, and they were all fine. Trying to measure a few currents here and there, Shaun looked for his multimeter and, oddly, it was on the workbench, not where he’d left. Not surprised, somebody must have used it and not stored properly, it happens. With his multimeter in hand, he started checking all currents and they all look fine, apart from the 17th onwards, that the polarity was reversed.
That was odd. Seriously odd. As if his machine was actually providing energy back to the power plant, only that it was impossible (it was no fusion chamber!). Without a clue, Shaun went back to his desk, left the multimeter by the lamp and reclined his chair, looking in the infinite. The infinite, in this case, was his shelf rack. Everything was blurred, but a remarkably familiar yellow blur caught his attention, and his eyes focused for a moment, and clear as day (though it was never day in his lab), that was his multimeter. Exactly where he’d left, with the dangling red wire over the black one.
He looked back at the table, and sure enough, his multimeter was there, too. Obviously, that one was someone’s else, but just to be sure, he got his own, and started comparing them, finding the same imperfections, the same burnt mark, the same cuts. His head was not working any more, he went back where he found the other multimeter and started looking around, looking for clues. It could very easily be a prank, but his head was not thinking. It was in discovery mode.
Obsessive as he was, he started noticing differences to that part of the room, compared to what it usually was. Almost like the room was displaced in time, with that part a few hours, maybe days, back. And he started putting things in their own place, tidying up as a mechanical task to help him think. When he was satisfied with the place, he turned around and jumped so high backwards that he hit his head on a red pipe that was hanging from the ceiling. It was Shaun, looking back at himself, smiling.
“Hello”, said the other Shaun. “…”. “Yes, I see, you’re in a bit of a shock. That’s understandable, I um, let me help you with the concept.” Shaun said nothing.
“See, you are a very interesting specimen. We’ve been monitoring your experiment ever since we detected the leakage from your universe to ours. Generally, we wouldn’t ourselves believe in multiple universes, but as things were clearly leaking from your universe, we had no other alternative.” Shaun was still speechless. “As you probably have guessed by now, this part of the room is in our universe. Actually, the working part of your experiment has been inside our universe for quite some time. More specifically, ever since it started working…”.
“Hey!” Shaun opened his mouth for the first time. “You can’t possibly say that you guys did all the work!” – without even knowing who were they, but that was too big an insult to let that one pass. “Oh, no, you got me wrong, Shaun. No, you’re absolutely right, you did everything. We just provided our universe to you.”. Shaun was speechless again.
“Understand, we’re in a somewhat different level of technology than you. In some cases, much more advanced, in others, much less.”, the other Shaun continued after a pause, probing for any offence that he could have made. “In practical matters, we’re much more advanced. Our universe has been extremely kind to us. We have a very dense population throughout our known universe, it’s actually hard to get to know all the cultures yourself, we just don’t live long enough. The fact that your universe has been leaking energy has boosted our physics so much, that we managed to halve the energy consumption of all our technology and at the same time, more than double our energy production levels!”, Shaun would not let that one pass… “Lucky you, we have nothing of that…”
“I know! Very well indeed! And it’s in that respect that you guys are so much more advanced than us. Your theoretical physics is so advanced, your mathematics so robust, that make our feeble attempts in model our universe a pre-school matter.” – “Ha!” said Shaun, “our mathematics is broken, Goedel has proven it and Turing re-proved. Our theoretical physics is still fighting over string theory and the alternative and we’re getting nowhere fast!”.
“On the contrary, Shaun. Your universe is limited, so your mathematics can only reach thus far. Your theoretical physics is considering things that we never imagined possible. Our universe is lame next to yours, the challenges that you face are the most delicious delicatessen for our theoretical physicists. There is an entire community, the fastest growing of all times, just to consume the material you guys generated three centuries (of your time) ago!”
The other Shaun was breathless, smiling from ear to ear with a face like a dog waiting for you to throw the stick. There was a deep silence for a few moments. Shaun was afraid that someone would enter through the door and he would have to explain everything, and he was not sure he could, actually. He was still holding the last tool he was going to put somewhere safe. He looked at it and considered that that tool was not actually in his own universe, but somewhere else. Yet, it was there, on the same room.
“So,” – a pause – “how come you are… me?”, “Well, I’m not you, obviously, I’m just represented as you in this piece of our universe. I wouldn’t fit this room otherwise.”, “Oh, I get it.” lied Shaun. The other Shaun continued “You see, your studies has allowed us to extrapolate you idea and re-create your own universe inside our own. This room is just the connection point, if you go through that door” – and pointed to an old door that lead to the emergency exit – “you will continue inside our version of your universe.”, “Wait a minute, how much of our world have you replicated?”, “World, no, not just Earth, everything.” – a long pause, with wide open eyes. After a blink: “you mean, galaxies?”, “Yes, yes, all of them. Your universe is quite compact for all it has to offer, and we were firstly intrigued by that, but then we understood that it was necessary to have the constraints you have, and well, an important feature to generate such high quality theoretical physics.” “And we decided to lend an unused part of our universe so you could not only teach us by broadcasting your knowledge, but also running tests on our own universe.” “Most of your experiments are now part of our day-to-day life, from vehicles to communication devices to life-saving machines.” “You, Shaun, has made our lives so much better, that it was the least we could do.”
“Is there anyone living in this version of our universe? I mean, human … hum … clones?”, “No, no. We thought that would be improper. We do try to live in it, just for the curiosity, actually. There are some holiday packs to travel the wonderful places your universe has to offer. It’s nothing we don’t see in our own, but you know, travel agencies will always find an excuse to take your money, right?” and finished that sentence with a grin and almost a wink. His human traces were very good, almost as if he was observing for far too long, making Shaun to feel a little bit uneasy…
“Actually…” – the other Shaun continued – “maybe you could help us fixing a few things on this side of the universe. Make things a bit more suited to the people from our side, what do you think?”. With the rest of the team deep in tests, it’d be weeks before they would even consider going back to the main lab, and nobody else would dare to enter there, after the several claims (in the private circle that knew him) that his lab would produce a black-hole that would consume Earth and everything else.
Shaun decided to go in, at least to explore the very convincing copy of his own world. Going up the emergency exit, he found the lift all the way to the top, as expected. Outside, as expected, the early rays of the spring sun casting long shadows on the trees and buildings. The nearby cattle farm was empty, though. When the other Shaun noticed Shaun’s curiosity, he added, “Ah, yes, you see, we decided not to include mammals, as they could eventually evolve into sapient beings and we’d be altering the history of our own universe. We didn’t want to do that!”. Shaun thought it was sensible.
For several days, Shaun has listened to all complaints about his own universe and how would that fit into their own physiology. Animals were turned green to photosynthesise, trees would reproduce by multiple ways at the same time, genetic combination of more than a pair of chromosomes were allowed, as was normal in this new universe, and many of the landscapes were altered to fit the gigantic stature of most of its inhabitants. Some parts were left untouched, or the travel agencies would lose a huge market, and some were shortened and simplified, for the less elaborate, but still pseudo-sentient species.
Shaun was feeling very well, like a demi-god, changing landscapes and evolution at his own wishes, much like Slartibartfast. How fortunate was him, the only human – correction – the only being in his universe (as far as he knew) to play with a toy universe himself.
After meeting with leaders of the populations of the alter-universe, receiving gifts and commendations (and a few kisses from the lasses), it was time to return to his own universe. Shaun felt a bit tired, but after drinking a bit of their energetic beverage, he blasted back to alter-Earth in his new hyper-vehicle, to his own alter-lab. In there, only alter-Shaun was there to say goodbye. A handshake and a wink was enough to mean “I’ll be back, and thanks for all the fish”, which Shaun has taken as a warm gift, rather than a creepy resemblance.
But as soon as Shaun stepped up into his own universe, he noticed some things were out of place. After being in an alter-universe for so long, it was only natural to misplace normal concepts, but some things were not normal at all, like a 10 meter high corridor leading from his side of the room. Normally, It’d be no more than 2 meters and there was a very good reason for that: humans are not that tall!
He ran through it to find a huge door to a huge lift. In the lift were a few people still discussing what had happened. “It was definitely not that big! We must have shrunk!” said one, “No, that’s not possible, that’s Hollywoodian at best!” said the sceptic. Shaun took the lift up to the ground level, and ran to the farm nearby, fearing the worst.
And the worst happened. The cows were green, and the houses huge. Being a bad theoretical physicist himself, and not being able to count on the alter-physicists for theoretical matters, Shaun hasn’t taken into account that his machine was a duplication machine, of entangled particles. That means, for the lay to understand, that whatever happens to one, invariably happens to the other, no matter in what part of the universe, or in this case, in the multi-verse, they are.
That, thought Shaun, would take a bit more than a few days to fix… but he know how, and he was looking forward to fix it himself!
