english: So the evidence that we have that a quarter of the universe is dark matter -- this gravitationally attracting stuff -- is that galaxies, the speed with which stars orbiting galaxies is much too large; it must be embedded in dark matter.
non_english: Znači dokazi koje imamo da četvrtinu univerzuma čini tamna materija -- ono što privlači putem gravitacije -- jeste da galaksije, brzine kojim zvezde orbitiraju oko galaksija jesu prevelike; mora da bude ugrađena u tamnu materiju.
