Webb11 apr. 2024 · Curve 4 represents a universe that is accelerating because of the effects of dark energy. The dashed line is for an empty universe, one in which the expansion is not slowed by gravity or accelerated by dark energy. Time is very compressed on this graph.

WebbWhat are the possible shapes of the universe? There are three general categories of possible shapes of the universe: open, flat, and closed. These adjectives refer to the kind of curvature that space has overall. Massive objects cause space to bend and curve; the universe itself is a massive object, so the entire cosmos is curved, too. Webb24 jan. 2014 · Recent measurements (c. 2001) by a number of ground-based and balloon-based experiments, including MAT/TOCO, Boomerang, Maxima, and DASI, have shown that the brightest spots are about 1 degree across. Thus the universe was known to be flat to within about 15% accuracy prior to the WMAP results.
