Standard Cosmological Models with Λ > 0 Can Best Approximate our Universe


Recent measurements of supernovae appear to have proven beyond a shadow of a doubt that the Universe is expanding at an accelerating rate. Most cosmologists disagree with these results, yet the presence of the positive cosmological constant answers the question. We show in this paper that simply changing the cosmological constant to a positive number, standard cosmological models may adequately explain our universe without the need for cold dark matter. We further emphasise that throughout the Universe, things travelling faster than light speed are physically feasible without contradicting Einstein’s postulates.
