Summary

Description
English: Left: A galaxy with a rotation curve as predicted before the effects of dark matter were known. Right: A galaxy with a flat rotation curve that can be explained by the effects of dark matter.
Deutsch: Links: Eine Galaxie mit einer Rotationskurve, wie sie durch die Keplerschen Gesetze vorrausgesagt wird, ohne die Annahme, dass Dunkle Materie existiert. Rechts: Eine Galaxie mit einer horizonralen Rotationskurve, wie sie empirisch beobachtet wurde und die mit der Dunklen Materie erklärt werden kann.
