Nasa researchers found that the majority of 263 observed galaxies rotate in the same direction.
This goes against previous assumptions that our universe is isotropic, meaning there should be an equal number of galaxies rotating clockwise and anticlockwise.
This observation potentially supports the black hole cosmology theory, which proposes our universe formed within a black hole.
An alternative explanation is that the Milky Way's rotation is having an impact on measurements, meaning scientists will need to “re-calibrate” them.
