It had been a concern for as long as anyone could remember. It was an issue that would, inevitably, spell the end of everything if a solution could not be found. After a time, it became all anyone talked about.
The gradual breaking down of systems, the slow movement of all matter and energy away from all other energy and matter.
It had first been hypothesized billions and billions of years ago. Someone pointed out that the Universe was either moving too slowly and would eventually collapse back in on itself under its own weight, or it was moving too fast and the various components would eventually scatter until the entire universe was nothing more than random molecules floating in empty space, so spread out and diffuse that they could not gather to form stars or planets or even comets. The universe was doomed either way, it was believed, but it would not happen for uncountable billions of years.
Uncountable billions of years passed, and the thought was still with people. It lingered in the back of scientific textbooks during the rapid, glorious expansion of the Hegemony. It was briefly popular as the cause célèbre during the height of the Spinward Empire. It rested, briefly forgotten, on inert data crystals during the Long Dark that followed the civil war that ended the reign of the Galactic Oligarchy. It was rediscovered during the Trader Prince era when worlds, long isolated, were connected again by a web of trade routes by independent ship captains, but it was relegated to the status of interesting but not pressing.
As the years crept swiftly by, the thought began to take on greater significance, first among the academic communities, then the scientific, and finally it reached the popular channels. People had adapted to live in conditions their ape-ancestor genes had never considered: the bottoms of worlds mostly made of water, in stations or hollowed out asteroids, in the dim crimson light of red giant stars. They lived on hot worlds, and cold worlds, and worlds where the air was full of trace compounds that made it poisonous to people at first, until they adapted. Worlds with higher-than-normal gravity, worlds with lower-than-normal gravity, worlds with no gravity at all. But the one thing all these worlds had in common was the need -for- worlds. People never did adapt to living in hard vacuum at temperatures so close to 0 Kelvins that the difference was purely academic.
And so the collective might of the universe was brought to bear on the issue. Science and industry turned away from the study of quantum teleportation and wormhole study, and focused on matters of gravity manipulation. It was theorized that if people could create artificial gravity, they could selectively ‘pull back’ the drifting, diffusing molecules and re-start stars, re-form planets.
Entropy would have its laugh however. They found ways to do this, but they cost so much in terms of energy use that it was actually a losing proposition for star rebuilding. Still, the people had fun walking on walls and ceilings for a few decades before that got boring and they relegated the use of gravity technology to vehicle transport.
The answer came, as is often the case, not from the major think tanks or the government agencies tasked with finding a solution. The answer, when it came, came from people on the so-called ‘fringes’ of the scientific community. Those who had continued to study the older sciences, who had not made the transition over to gravity study. People who studied things like ‘quantum entanglement’ and ‘string physics’ and ‘membrane theory.’ In particular, it was the last that was the salvation of all.
“We cannot stop Entropy,” the spokesperson said, “for Entropy affects even attempts to stop Entropy. Our universe is going to die. What we can do, however, and what we need to do, is to harness the energy we have left and use it to escape this universe. We shall open a breach, a portal if you will, to another membrane, another universe. A younger universe. We will then step across into this new universe, where we can use all the other sciences and technologies we have invented in the last billion years to make it our new home.”
And so the largest exodus the universe had ever seen began. Billions of worlds, each containing billions of people, threw every resource into opening portals. The new universe that the scientists had discovered groaned under the weight of all these new refugees. It did not take long before the scientists of one world, moving forward from the research that the others had laid down, found a way to go to another young universe. Why, they reasoned, should we share our universe with all those other people when we can have an entire one all our own? Other worlds saw what they had done and did likewise. And rather than one universe with the inhabitants of billions of worlds, there were billions of new universes, each with only one world’s worth of inhabitants.
And the people looked at their new universes, full of new stars and new worlds and energy to last trillions upon trillions of years, and they saw that it was good.
Yeah, it’s more than 500 words. My blog, I can do that if I want. So nyah.
