How much mass does the universe have

WebMay 21, 2024 · And then multiply by the volume of the observable universe. Since you're probably going to be comoving that is your available total energy. The numbers are easy enough. Critical density is about 10 − 26 kg/ m 3. This includes the mass equiv. The radius is 46 Gly, and volume you can compute to be about 10 80 m 3. WebFor centuries, physicists thought there was no limit to how fast an object could travel. But Einstein showed that the universe does, in fact, have a speed limit: the speed of light in a vacuum (that is, empty space). Nothing can travel faster than 300,000 kilometers per second (186,000 miles per second).

WebGravitational energy from visible matter accounts for 26–37% of the observed total mass–energy density. [14] Therefore to fit the concept of a "zero-energy universe" to the observed universe, other negative energy reservoirs besides gravity from baryonic matter are necessary. These reservoirs are frequently assumed to be dark matter. [15] my coffee is strong and so am i
