english: How? Well according to Einstein's math, if space is uniformly filled with an invisible energy, sort of like a uniform, invisible mist, then the gravity generated by that mist would be repulsive, repulsive gravity, which is just what we need to explain the observations.
non_english: Kako? Prema Ajnštajnovoj matematici, ako je svemir uniformno popunjen nevidljivom energijom, nečemu nalik uniformnoj, nevidljivoj magli, onda gravitacija koju ta magla generiše mora da bude odbojna, odbojna gravitacija, što je upravo to što nam treba da objasnimo ova zapažanja.
