When i was having fun with the system i loaded ( Earth,moon,sun ) i smashed Ceres into the Earth and fast forward to 5.9 days per second and the earth cooled but with a somehow different continent? but it was frozen and all icy? but there is water on the surface and the temperature was -273 degrees, i was shocked when i saw the video about collision and the earth somehow returned to its normal state but when i tried to follow it the same thing happened even though i changed the temperature to 14 degrees it still cools to negative... i checked the distance and it is at the habitable zone and it is a loaded file from the game itself?
can anyone explain how this is?
