SCP-225: Unstoppable and Immovable

SCP-225: Unstoppable and Immovable SCP-225 consists of two gray metallic spheres, each a little under seventy centimeters across. One stays in the same position above the ground. The other moves along a path near Earth's orbit. Neither has responded to any force or weapon the Foundation has tried. The concern is what happens if their paths meet. The first sphere hangs 7.3 meters above the surface at Site-65. It cannot be pushed, pulled, damaged, or carried away. Containment does not require guards for the object itself because nobody can steal it. Researchers are trying to find some way to destroy it or gain control over its position. Calling it motionless needs a qualification. It remains fixed relative to the ground while Earth rotates and travels around the Sun. The file calls this geosynchronous, although its position so close to the ground is not a normal geostationary orbit. Holding that position despite every tested force is part of the anomaly. The second sphere follows a different course around the Sun, roughly matching Earth's travel without behaving like an ordinary orbiting body. The file says it appears to propel itself by unknown means. Earth's rotation makes it seem to pass around the planet at roughly 1,600 to 2,000 kilometers per hour. Its distance from Earth varies, and its course is not completely predictable. Unlike the first sphere, this one cannot be kept at a facility. It destroys or displaces anything in its path without slowing down. The Foundation tracks its position, speed, and direction, maintaining projections fifty years ahead. Contact was once lost when it moved farther away and was restored after a redacted lunar impact incident. The file gives no detailed account of that event. So far, the traveling sphere has never been observed below ten kilometers in relative altitude. That leaves a substantial separation from the sphere near the ground. There is no immediate collision warning, and the pair remains classified Euclid. A probable collision would change that immediately. The file calls for Keter classification, every available Foundation resource, and planetary evacuation planning. One modeled outcome assumes that the spheres annihilate each other and release an enormous amount of energy. The report treats that as one possible outcome. Resistance to every tested force has not established how these two unknown objects would interact with each other. The other possibility is that neither sphere gives way. The consequences of that scenario are redacted, including a warning that leaving Earth might not be enough. The Foundation has an extensive response plan for the encounter, but it has not found a way to change either participant's behavior. Original Entry: https://scp-wiki.wikidot.com/scp-225
