New study sows doubt about the composition of 70 percent of our universe
Until now, researchers have believed that dark energy accounted for nearly 70 percent of the ever-accelerating, expanding universe. For many years, this mechanism has been associated with the so-called cosmological constant , developed by Einstein in 1917, that refers to an unknown repellant cosmic power. But because the cosmological constant—known as dark energy—cannot be measured directly, numerous researchers, including Einstein, have doubted its existence—without being able to suggest a viable alternative. Until now. In a new study by researchers at the University of Copenhagen, a model was tested that replaces dark energy with a dark matter in the form of magnetic forces. “If what we discovered is accurate, it would upend our belief that what we thought made up 70 percent of the universe does not actually exist. We have removed dark energy from the equation and added in a few more properties for dark matter. This appears to have the same effect upon the unive...
