Robert Pattinson is interested in the Stars, and Stardust. not Alvin Stardust, the English Pop Star. of the 70s and 80s.
Pattinson explained "I am interested in Astronomy and the planets in our solar system, and the fact that everything is made from stardust.
When a star is born even the planets, that form and orbit round it are made from stardust. On planet earth everything that we see is made from the atoms of stardust including rivers , oceans, mountains and every living thing that exists including yourself.
Everything that exists therefore in the Universe, is in fact formed from the atoms of stars, formed from previous stars that have gone super nova.
