Hubble detected a red shift in the light from all objects within galaxies he observed. This would indicate-

• an implosion of the universe

• all galaxies are moving away from all other objects

• a counterclockwise moment of the universe

• a clockwise motion in the universe

The solar nebula that formed our solar system was thought to be put in motion by a -

• nearby supernova

• black hole

• creative intelligence

• condensation nucleus

Our understanding of nebulae has been greatly enhanced by-

• undersea exploration
