Geneticists and scientists have found that our perfect wake and sleep cycle is more tuned to Mars's rotation on its axis than to Earth's, as Mars has a slightly shorter day. The Milky Way galaxy is currently absorbing the Sagittarius dwarf galaxy, not visible as previously thought, and this merging point coincides with our solar system, explaining the existence of rogue planets. Our solar system is believed to have come from Sagittarius and is now an implant into the Milky Way galaxy. The Kuiper Belt holds various small objects, leading to Pluto's reclassification as a dwarf planet, and there is a belief in the existence of a large unidentified object based on gravitational responses.
