Summary

Description
English: Diagram of the size of the universe over time from origin at t = 0 to time of universe t_U. The particle horizon is constantly expanding with the speed of light c:

Radius of end of inflationary period (Schwarzschild radius of universe): r_S = t_U * c = 14283 Mpc = 46,6e9 ly

Co-moving radius of the cosmic microwave background (CMB): r_CMB = 14000 Mpc = 45,7e9 ly

Hubble radius at Hubble time t_H: r_H = t_H * c = 4480 Mpc = 14,6e9 ly

Radius of visible universe:

r_V = 4230 Mpc = 13,8e9 ly
