Astronomen gehen seit Jahrzehnten davon aus, dass sich das Universum in allen Richtungen gleich schnell ausdehnt. Eine neue Studie, die auf Daten der XMM-Newton-Mission der ESA, der NASA-Mission Chandra und des deutschen ROSAT-Röntgensatelliten (DLR) basiert, legt nahe, dass diese Schlüsselprämisse der Kosmologie falsch sein könnte.

Rethinking cosmology: Universe expansion may not be uniform

Astronomers have assumed for decades that the Universe is expanding at the same rate in all directions. A new study based on data from ESA’s XMM-Newton, NASA’s Chandra and the German-led ROSAT X-ray observatories suggests this key premise of cosmology might be wrong.
