Synopsis

Vom Kleinsten zum Größten führt die heutige Reise: Carl Sagan berichtet über Atome und schildert dann, wie sie im Innern der Sterne entstehen. Wichtigstes Reiseziel: die Sonne. Sie ist eine Kugel aus glühendem Wasserstoff. Das heiße Gas im Innern bewirkt, dass sie sich ausdehnt, die Schwerkraft, dass sie sich zusammenballt. Der jetzige Zustand ist das Gleichgewicht beider Kräfte. Wenn der nukleare Brennstoff verbraucht ist, wir die Sonne in sich zusammenstürzen.
