Analysis combines Dark Energy Survey and South Pole Telescope data to understand evolution of universe. Sometimes to know what the matter is, you have to find it first. When the universe began, matter was flung outward and gradually formed the planets, stars, and galaxies that we know and love t
, which looks for the faint traces of radiation that are still traveling across the sky from the first few moments of the universe.
By rigorously analyzing these two sets of data, the scientists could infer where all the matter ended up in the universe. It is more precise than previous measurements—that is, it narrows down the possibilities for where this matter wound up—compared to previous analyses, the authors said. That is, if you make a model incorporating all the currently accepted physical laws, then take the readings from the beginning of the universe and extrapolate it forward through time, the results look slightly different from what we actually measure around us today.
