Is the observable universe expanding
The expansion of the universe is the increase in distance between any two given gravitationally unbound parts of the observable universe with time. It is an intrinsic expansion whereby the scale of space itself changes. The universe does not expand "into" anything and does not require space to exist "outside" it. This expansion involves neither space nor objects in space "moving" in a traditional sense, but rather it is the metric (which governs the size and geometry of spacetime it… Witryna9 kwi 2024 · The cosmic distance ladder is also used to measure the expansion rate of the universe, known as the Hubble constant.

Since the universe has been expanding for 13.8 billion years, the comoving distance (radius) is now about 46.6 billion light-years. Thus, volume ( 4 3 πr3) equals 3.58 × 1080 m3 and the mass of ordinary matter equals density ( 4.08 × 10−28 kg/m3) times volume ( 3.58 × 1080 m3) or 1.46 × 1053 kg .
