A competing theory posits that the universe is expanding ever more rapidly because gravity acts differently at very large scales from what Einstein's theory predicts. WebA Minkowskian solution of the equation of General Relativity (as written by Einstein in 1915) is trivial because it simply means that both members of the equation are equal to zero. However, if alternatively, one considers the complete equation with a non-zero constant Λ (Einstein 1917), a Minkowskian solution is no longer trivial because it amounts to impose …
