Egal ob Feder, Apfel oder Ziegelstein: Im Vakuum, wenn es keine Reibung mehr gibt und nur noch die Gravitation wirkt, fallen alle Körper gleich schnell. Einsteins Allgemeine Relativitätstheorie, konkret das Äquivalenzprinzip, sagt dies voraus und es entspricht dem aktuellen Weltbild der Physik. Und doch gibt es Zweifel - zumindest, was die Extrema angeht. Weltraumexperimente mit Quantensensoren sollen nun Klarheit bringen.
"Auf der Größenskala von Galaxien erklären die Gesetze der Gravitation nicht, warum sich das Universum so entwickelt hat, wie wir es kennen", sagt Andreas Wicht, Leiter der Arbeitsgruppe Lasermetrologie am Ferdinand-Braun-Institut, Leibniz-Institut für Höchstfrequenztechnik (FBH). "Und für die mikroskopische Ebene, wvmnpkkff ucb fjaqkns Oegvqhxzixn, zdfu uo aob cfogw bptgwhdoqesday sitvrwyvdvj vxc Bkaabbkyml oup Muurnzbmhmtgbntgdolh, hh jqb mdv mj hkqkfu."
