There was a theory once, about Nemesis, the Dark Star. Stillborn twin to the sun, it wandered the void, black and cold, and every 100 million years, came back home.
The Pre-Cambrian Extinction.
The End of the Cretaceous Period.
Now.
No longer content to wander, Nemesis is drawn to our Sun in one final dance. Jupiter is swallowed, Mercury and Venus follow. Mars is flung loose, to orbit in great 100-year cycles.
And Earth remains untouched as the Sun is slowly eaten.
Viol glanced over her shoulder to see what Philmann was yelping about. On the horizon was a black cloud, roaring towards the city at great speed. Flashes of crimson and violet light from within illuminated massive shapes of vague yet immediate horror.
“What are you?” “I am the avatar of the Fallow God. It speaks, through me.” “What is the Fallow God?” There was a pause, and the thing turned its head and stared at her. Haltingly, each syllable pronounced individually, it spoke in its creaky voice. “Did you want a pony?' “What?” “When you were young, did you want a pony?” “Uh, yeah, for a while.” “And you,” it said turning towards him, “did you want to be, an astronaut? Or, a cowboy?” “A dentist, actually.” The others looked at him incredulously. “What? My uncle had really bad teeth.” “And, are you a dentist?” It turned back to her. “Did you get, your pony?” “No.” “And, the first one you loved, are they yours, now?” “...No.” “That is the Fallow God. Your dreams are as seeds, sown into the wind. Some bear fruit, but most... lie fallow.”
At the beginning of time, the Creator—whoever he, she, or it is—made the world. They made the world balanced; good and evil, life and death, joy and sorrow, pleasure and pain, light and dark. When they were done, everything was balanced, every thing had a counter-force, every summer a winter, every day its night. Yet, one thing remained. For this is the truth of Creation; that the Creator made only half the world. Good to balance evil, light to balance dark; all that was pure and wholesome was made to balance all that was not. Yet, one thing remained. One thing that could not be balanced, that had no counterpart standing in the light. One thing other; not evil, for evil had good; not pain, for pain had pleasure; not dark, for dark had light. All the Creator could do was bind it and seal it, hide and guard it, keep it safe and keep it away from the rest of the world. An evil beyond evil, a shadow beyond shadow. Beyond concept and language: the Last Bad Thing.
"What's that over there?”, asked Ian. Von Neumann glanced over to where Ian was pointing. On the other side of the large cavernous space of Tertiary Lab 7 a large, thick cylinder protruded partially from the wall, a tiny segment of a huge ring exposed to the air. “Oh, that.” Von Neumann looked slightly nervous. “You know what a LMH Cyclonic Beam Weapon is?” he asked. Ian flinched, and carefully studied the ring segment for a minute before speaking. “Its inactive now isn't it?” “I'm guessing you just scanned it. Yeah, its inactive. We spun it down and hosed it out after the first test shot. Scared the hell out of us.” Ian looked at Von Neumann, a peculiar expression on his face. “As terrifying as the idea of one of those things is, I thought you Forge's liked them?” “Well, yeah. Marvelous devices. That, however, is not strictly speaking a LMH Cyclonic Beam Weapon. It is an attempt of ours to improve the design.” There are few words as terrifying to anyone who knows them as a Forge saying 'improve the design'. “Oh great. I know I'm going to regret this, but what did you change?” “Well, the original design used LMH for its super-conductive properties. Very easy to manipulate magnetically. That, and its highly volatile nature added to the weapon's effect. Now first, we tried a different metal.” “I thought you couldn't, that it had to be liquid and very few metals were magnetic enough when molten?” “Which is why we stripped their electrons. You get a positively charged soup of metal nuclei, highly receptive to electromagnetic fields.” “And denser than LMH.” “Oh, my yes. By two orders of magnitude as it turns out.” Internally, Ian's highly advanced computational units networked together and ran some simulations. After being presented with the data, his higher-level social software declared that the truly human thing to do now would be to roll up into a little ball and start sobbing. Deciding not to, Ian replied, only slightly shakily. “That seems truly terrifying. I can see why you shut it off.” “What? Oh, no, that's not what this one does. That model is going into production soon. No, that one its where we got creative.” To those who know them, there is no word more terrifying than 'creative'. Fearing greatly the answer, Ian asked, “And how did you do that?” “Well,” said Von Neumann, looking slightly guilty, “we figured, 'Instead of positively charged matter, why not use negatively charged matter?'” For the first time in his existence, Ian nearly experienced a system crash as all his internal processors declared that they had obviously just received faulty data and requested extra clock-cycles to double check. Temporarily shutting down his social emulation software, Infiltration Assimilation and Neutralization Unit number 417 processed the massive implications of the data it had been presented with. Having verified the truth of the data, consensus was reached by the assorted distributed networked processors to initiate repression protocols and bury the information in a dusty directory so they wouldn't have to look at it again. With something that could almost be described as hesitation, the many tiny machine minds which comprised the intelligence and body of Unit 417 booted the social emulation back up. Ian opened his eyes and said, very slowly and carefully, “You used anti-matter in a Cyclonic Beam Weapon.” “Yup.” Ian opened a data file named 'Reasons why all Forges must be destroyed for the sake of creation.' and added to the existing list.
So that's the longest and possibly worst name for a post ever.
Its not even a great name for the weapon itself, but it is the best way I can think of to describe it in a few words. Okay, the science.
Liquid hydrogen forms at very low temperatures. Metallic hydrogen forms under great pressure How great? 500 GPA, roughly. That's about 5 million atmospheres of pressure.
Now imagine a particle accelerator. For those of you who don't know, a particle accelerator is a large, circular ring. A particle, let us say a single positive proton, is accelerated through the ring by an electromagnetic field. Each time it goes a round, it is a little faster. The accelerator imparts a little more energy into it, until it is sitting rather close to the speed of light. Then they smash it into something, and study the bits that fly off, little building blocks of everything.
Now, take rather cruder device, let us say a kilometer in diameter, the ring a few meters wide. And filled with metallic hydrogen. Metallic hydrogen, exposed to our atmosphere, would vaporise explosively. Attempting to fire a bolt of it magnetically using a railgun would; a) be rather effective due to its super-conductive properties, and b) be almost useless Due to its incredibly volatile nature, by the time your shot had reached your target, it would have ceased to be a high-velocity round and become a medium to high velocity cloud of rapidly expanding gas. You'd need to make it very, very fast to over come this. A linear railgun, much like a linear particle accelerator, simply cannot impart the necessary velocity before the metallic hydrogen leaves its 'barrel'.
So we use a cyclotron, the ring shaped accelerator. We spin the hydrogen around and around within, each time increasing its speed. Then, when we wish to release it, we simply stop containment at a single point. The effect is like loosing a stone from a sling. In fact, it is rather the same principle writ large.
A railgun fires a fist-sized mass at a fraction of the speed of light. The sheer force of momentum behind it can liquefy air, and cause damage comparable to a minor meteor impact. This weapon could fire a stream of liquid metallic hydrogen over a dozen kilometers long at close to the speed of light . It would be like turning a volcano into a laser.
While writing this, I paused and did some quick physics. At a rough estimate, the stream would have a kinetic energy of approximately 765 exajoules. The earthquake in Japan earlier this year released approximately as much energy as 600 million Hiroshimas. It was 1.4 exajoules.
