70-26-4: The Cosmic Mix Confirmed
New results from the Dark Energy Survey confirm that the Universe is mostly made of dark energy (70%) and dark matter (26%), with normal baryonic matter comprising just a smidge (4%). In other words, the Universe is mostly made of stuff we don’t understand! The results of the survey, which is being carried out with DECam on the CTIO Blanco telescope, were derived from high precision maps of gravitational lensing and large scale structure.
