00:00A group of dwarf galaxies has been found aligned in a straight line, rotating in the same direction, challenging the cold dark matter theory.
00:09Scientists believe warm dark matter may better explain this unusual alignment.
00:14The group, located 117 million light-years away, consists of at least five galaxies spanning 502,408 light-years in a vertical line.
00:24Three of the galaxies in the group share the same direction of rotation as observed by the Dark Energy Spectroscopic Instrument.
