Researchers in Switzerland have introduced a new way of evaluating Albert Einstein’s equations of gravity to find a value for the cosmological constant that closely matches its observed value by adding an additional equation on top of Einstein’s field equations. In their modification of general relativity, the gravitational constant remains the same within our observable universe but may vary in a multiverse scenario where there may be patches of the universe invisible to us that have different values for the fundamental constants. Using this they found the universe is made up of about 74% dark energy. This number closely matches the value of 68.5% estimated from observations. The framework might solve the cosmological constant problem, but there’s currently no way to test it…read more. Open Access TECHNIAL ARTICLE
