When we think of the Big Bang, we think loud, hot, and bright. But was it followed by a colder, darker shadow?
Behold the limitless, crowded cosmos. The Dark Energy Spectroscopic Instrument (DESI) Legacy Imaging Survey has put out its latest data release, increasing the size of the largest 2D sky map.
Researchers used data from the Dark Energy Survey and the South Pole Telescope to re-calculate the total amount and distribution of matter in the universe. They found that there’s about six times as much dark matter in the universe as there is regular matter, a finding consistent with previous measurements.
