That distracted him. Just out of pure curiosity, then, he said, “Why are your civilizations centered around nebulae?”
Clarification: Nebulae are centered around our civilizations. They are favored locations, since density of interstellar medium is thicker, hence travel expense by ramscoop ships is less. Also, in stellar nurseries, young and energetic stars are at hand for large-scale engineering projects.
The screens opened up with a second group of images. To his surprise, among the many stars and wonders he did not recognize, the images included many of the areas of space Blackie had been investigating so carefully so many years ago: the giant planets circling Hipparchos 13044 and HD 42176 in the constellation Auriga; a pulsar in Cygnus; on a larger scale were shown the expansion motions of the Local Interstellar Cloud; the star-making activity of the Great Nebula in Carina; and on yet a larger scale was shown the Mice Galaxies and Mayall’s Object and the triple collision of galaxies at ESO 593-IG 008; and the motion of Andromeda toward the Milky Way.
“Hold up. All these things are artificial? The universe is not the way it would naturally be—because it is all being cultivated, colonized, and reengineered!”
The alien abomination seemed to evince a human emotion: puzzlement, disappointment, exasperation. The giant star Mira is passing through this area at 291,000 miles per hour, a velocity sufficient to create a trail of debris and ejected streamers thirteen lightyears long. It is less than 300 lightyears from you. Surely you did not think this a natural phenomenon?
“Um.”
He wished that the history-making diplomatic dialog with a malign alien superintelligence did not contain him making a dull noise in his throat, but the serpentine must have translated it as a request for clarification, because the entity spoke again.
The Host of Mira accelerated their star out of its orbit around the galactic core in a vain attempt to flee the Forerunners who in ancient times were Archon of the Orion Arm. The dead Solar System was allowed to career onward as a warning to others. Natural phenomena are regular and repeatable, whereas no other star exhibits such extreme behavior. How could your race fail to notice this?
“All our resources were preoccupied with SETI research, I reckon.”
The serpentine must have sent a very diplomatic version of that comment, or else the entity was in a talkative mood, because it answered: A simple calculation shows that the rate at which nova and supernova stars ignite, and their distribution, is artificial. The ignitions take place away from delicate operational centers, but periodically are used to seed heavier elements into the galactic background, to allow for the rise of new life. Galaxies who fail to do so perish due to a lack of new civilizations to replace dead cells in their mental system, or else migrate to richer areas.
Another calculation shows the impossibility of so many spiral galaxies and galactic collisions, or the creation of walls and voids amid the superclusters.
The spiral motion is imparted to elliptical and irregular galaxies in order to force interstellar organizations to form coherent bonds with distant stars more homogeneously.
Montrose said, “And to think, all this time people wondered why there were no signs of alien life among the stars. There were plenty of signs. They were just too big to see.” He had read somewhere, perhaps in a comic, some half-serious maxim called Shroeder’s Law: Any sufficiently advanced technology is indistinguishable from nature.
Man on Earth had been sitting in the middle of the industrial activity of extraterrestrial civilizations for its entire life, everything from pulsars to nova stars to the shape of the galaxy itself, and thought it was all natural.
He wondered if some tiny mites born in a cathedral would develop cunning theories about the evolution of the pillars and the stained-glass windows, or look at the curve of the Gothic arch, and be awed by Mother Nature’s mathematic perfection. “Well, Mother Nature has a hairdresser, don’t she?”
And it meant the Monument notation was not mad at all. This was not a universe where one could divide by zero. The math was sane.
He and Blackie had just made a simple but erroneous assumption. Knowing that Hyades could build an antimatter star was not something that naturally allows a man to make the leap of assuming that a mind composed of tens of millions of self-aware solar systems in the Andromeda Galaxy had deliberately set their galaxy on a collision path across the millions of lightyears to ram the Milky Way.
The serpentine said, “Sir? Do you want me to send your last comment?”
7. Not Uncivilized
Montrose shook himself out of his reverie. “Negative. Ask him this: some of the material in the nebulae is the byproduct of industrial activity. What is the rest?”
Other material is the residuum of ancient military actions.
“War?” Montrose remembered wondering why so many of the galaxies looked torn and scarred. He felt the fool for not realizing that they were.
He imagined a precocious mite living in a cathedral that was being bombed. The whole life of the mite was part of a single second, and to him the picture was frozen. The shattered glass in the window as it fell would be a natural phenomenon, the shrapnel holes in the pews, and the flames burning the roof. He would have no other cathedrals to compare it to, and would simply keep changing his theories until they fit what he saw. When he concluded all roofs naturally burst into flame after a certain point in their roofly evolution, perhaps he would climb the steeple and look outside, and see the other buildings in the neighborhood, see their roofs all blazing.
The precocious mite would congratulate himself on his theory, and sit in awe, staring at the natural wonders of the universe, just as Montrose had stared at the exploding stars and smoldering nebulae and colliding galaxies.
Surely your astronomers have noticed the war damage near your star: the Crab Pulsar is the remnant whose shock wave reached Sol in A.D. 1054. It is only 6500 lightyears from you.
“We thought it was a supernova.”
So it was.
“We thought it was a natural phenomenon.”
That is a limitation of your perception.
Montrose had no rejoinder to that.
We know your race is aware of the antimatter stars. Surely you did not think them natural? They are placed in areas where starfaring races are likely to be encountered.
“Near curious sights, in other words. But what if a race is not that curious?”
Races without a requisite degree of curiosity cannot develop the scientific and technical skills needed for starfaring. When such a race is encountered, they are obliterated to make room for more useful races. Your race unwisely broadcasts electromagnetic signals from your home planet during your pre-starflight era. It is fortunate that you encountered us before we encountered you.
Montrose felt a moment of stomach-wrenching disorientation. Captain Grimaldi commanding the first expedition to the Diamond Star had ordered the expedition never to return home, so that they would not lead the Hyades back to Sol. It was to defy that order that Del Azarchel, then the ship’s pilot and senior officer of the landing party, had committed murder and mutiny. But if Grimaldi’s order had been carried out, and if by some other means Hyades had become aware of Earth’s existence, mankind would have been exterminated. In this strange universe, a lack of curiosity was a capital crime. Did that mean Blackie was right?
