Mathematicians are challenging the idea that dark energy is responsible for the accelerating expansion of the universe. The mathematicians provide mathematical proof that instabilities inherent in the Einstein-Euler equations imply that the current model of the expanding universe is not viable.
New research suggests that our universe has no dark matter. A study, published today in The Astrophysical Journal, challenges the current model of the universe by showing that, in fact, it has no room for dark matter.
