Dark energy hides behind phantom fields
Madrid, Spain (SPX) Mar 31, 2014
Quintessence and phantom fields, two hypotheses formulated using data from satellites, such as Planck and WMAP, are among the many theories that try to explain the nature of dark energy. Now researchers from Barcelona and Athens suggest that both possibilities are only a mirage in the observations and it is the quantum vacuum which could be behind this energy that moves our universe. Cosmologists believe that some three quarters of the universe are made up of a mysterious dark energy which would e ... read more
