The universe began to expand at a constant rate: no one knows if it is a forever upward thing, of if it will contract. The explosion caused matter to be distributed inhomogeneously lumpiness begin to grow. Lumps of denser matter become centers of high gravity and. Eventually the lumps became large stars becoming galaxies. Formation of solar systems and earth: as it gets bigger and bigger it shapes its self into perfect spheres. Solar system: planets orbiting around a single sun. This sunspot activity affects the earth: the earth has a magnetic field which deflects the solar wind.
