Across the universe, this requires enough energy that the equivalent mass would be nearly fourteen times greater than all the visible material in existence. WebbLike dark matter, cosmic inflation (even if it is not actually proven beyond all doubt) is now usually seen as part of the standard Big Bang theory, and to some extent the two additional concepts rescue the Big Bang theory from being completely untenable.

Webb12 okt. 2024 · The evolution of the Universe is governed by the amount of dark matter and dark energy it contains, but the densities of dark matter and dark energy—their concentrations within a given volume of space—are affected very differently by cosmic expansion. We have a good idea of how much dark matter the universe holds, and … WebbThe dark energy from virtual gravitons is consistent with observational data on supernovas with the same accuracy as the ΛCDM model. The fact that virtual gravitons are capable of producing a de Sitter accelerated expansion of the FLRW universe was established in 2008 (see references).
