The aliens of Altair Six developed an interstellar drive – but it required such immense amounts of energy that the probe sent through the time/space vortex could be no larger than a mote of dust and the temporal rift so unstable that only one blurry image could be sent back.
They had established Earth as a good candidate for life and the high priests had blessed the probe (they had long ago abandoned the difference between science and religion – both relied on faith) and were confident that if life existed on the distant rock, it would show up in the image.
They were right. The single image returned showed an ordered collection of what were undoubtedly life forms. But exactly what were they looking at? Why were the individuals on one side all bedecked in bright white, while the others shone blazing red?
The debate raged on Altair Six. The accepted theory is one of racism – the photo showed a border with the white-lighted denizens restricted on one side, the red on the other. There is obviously no mixing of the two races – the apartheid is complete.
Others believed the dichotomy was age-based. Noting that the white creatures shone brighter than the red, the theory was advanced that the red were larval forms, while the white were full-grown. It was thought that they were separated to keep the developed individuals from eating the fry.
One controversial idea, put forth by Professor Yo’rin Cake of the University of Vultur Volans that the objects in the image aren’t actually life forms, but some sort of dwelling. The color of the lighting, red or white, is merely a marker to help delineate different neighborhoods.
This was dismissed by the learned councils out of hand. It was considered impossible to have that many dwellings in the image without capturing any of the life forms themselves.
Still, the debate between these and many other factions, some completely ridiculous, others more studied and mainstream, continued and only grew in intensity and cacophony. In an attempt to find an answer to this question an enormous portion of Altair Six’s economy was dedicated to building a huge power facility and a corresponding time/space vortex generator. The plans were laid to send a larger probe with a better camera and more sensors to finally answer the mysteries of the rock called Earth.
Unfortunately, their reach exceeded their grasp and the interstellar probe complex broke down and exploded. It was a terrible planet-wide disaster and set the society back by millennia. They were reduced to a level of advancement only slightly higher than ours.
