Einstein auf dem Prüfstand - zwei Präzisionsexperimente mit Lasern aus Berlin im Weltraum

Erfolgreiche Tests der Projekte KALEXUS und FOKUS an Bord der Forschungsrakete TEXUS-53 in Schwerlosigkeit durchgeführt

(PresseBox) (Berlin, )
Albert Einsteins Relativitätstheorie zufolge werden im Vakuum alle Körper, unabhängig von ihren sonstigen Eigenschaften, gleich schnell durch die Erdanziehungskraft beschleunigt. Dieses Äquivalenzprinzip gilt für Steine, Federn und Atome gleichermaßen. Unter den Bedingungen der Schwerelosigkeit kann besonders lange und damit präzise gemessen werden, ob verschieden schwere Atome tatsächlich „gleich schnell fallen“.

Für die ersten Präzisionsmessungen im Weltraum mit kalten Atomen sind Kalium und Rubidium als Atomspezies geeignete Kandidaten. In Vorbereitung auf diese Messungen wurden am 23. Januar in Kiruna, Schweden, gleich zwei Experimente erfolgreich auf einer Höhenforschungsrakete durchgeführt. Dies hat nun eine erste Auswertung gezeigt.
