Let's briefly consider the mathematics of this situation. I made a pretty basic illustration of this, shown below: This means that if the universe is infinite and contains an infinite number of bright objects, the night sky will be bright! Since the night sky is dark, this tells us that one of our assumptions about the universe is incorrect. If this is true, then every sight line from the Earth will eventually intersect a bright object. The reason that this question is so important is because its answer can tell us about the distribution of stars and galaxies in the universe.Ĭonsider the possibility that the universe is infinite and that it is filled with luminous objects (stars and the galaxies that contain them). Olbers), and it can be stated pretty simply: ![]() The question is usually called Olbers' Paradox, (after German astronomer Heinrich W. There is an old, simple question that can help us to understand a fundamental property of the universe. Observations and some implications: Olbers' Paradox and the Dark Night Sky.However, the bitterly cold temperatures and almost unrelenting winter makes life on the surface of Reisum nearly unbearable. From the frost covered mountain peaks to the snowy tundra, it is a thing of beauty. The world of Reisum is deceptive in its nature. The Urikki are predators by nature, hunting not only the creatures that inhabit the land but also those that dwell in the vast oceans. These long, slender vessels are adorned with runes and pictograms exalting the clan’s greatest deeds and celebrate its bravest warriors. Urikki tribes often employ ice skiffs to ply the vast distances of the open steppes and patches of exposed sea. A single Warren can contain up to a hundred different families. They have massive families that often number in the hundreds, if not thousands. The Emin cannot endure the harsh conditions of Reisum’s surface, so instead they occupy large underground networks of tunnels. Only the brutal Urikki are hardy enough to thrive in the frigid temperatures and severe conditions. Harsh and unforgiving, the surfaces of Reisum are considered uninhabitable to most. Only a remnant of mankind remains, hunted to near extinction by horrors from another world. ![]() The past sins of man lay buried here among the ashes as does the potential solution to severing the Root's grasp on Earth. The first Ward and origin of the top secret Dreamer program. Not even the most remote rural locations were safe from their reach. Once the cities fell, the Root expanded outwards in their unrelenting assault on humanity. The ground is scarred with deep ravines and chasms created when the roots of the massive tree system ravished and upturned the land. The Canopy is a hotbed of Root activity, and gets its name from the massive arboreal expanse covering the sky and blotting out the sun. Earth Subwayīeneath the city sprawls a network of broken subway tunnels and rancid sewage corridors, with enemies lurking in dark spaces and around every twist and turn of the labyrinthine tunnel system. The ruined cityscape reflects the chaos of that time – debris-ridden streets and gutted buildings set against a backdrop of broken skyscrapers.
