The Hubble volume is approximately equal to 10 31 cubic light years (or about 10 79 cubic meters). The proper radius of a Hubble sphere (known as the Hubble radius or the Hubble length) is , where is the speed of light and is the Hubble constant. The surface of a Hubble sphere is called the microphysical horizon, [2] … See more In cosmology, a Hubble volume (named for the astronomer Edwin Hubble) or Hubble sphere, subluminal sphere, causal sphere and sphere of causality is a spherical region of the observable universe surrounding an … See more The Hubble length $${\displaystyle c/H_{0}}$$ is 14.4 billion light years in the standard cosmological model, somewhat larger than $${\displaystyle c}$$ times the age of the universe, 13.8 billion years.
