# Einstein's radius of universe

### From Conservapedia

**Einstein's radius of universe**, usually denoted in cosmology by *R*_{E}, is the radius of curvature of space of Einstein's universe.

The exact length of **Einstein's radius of universe** is , where where *c* is speed of light in vavcuum, *G* is Newtonian gravitational constant, and ρ is density of space.

Assuming that we live in stationary (neither expanding nor contracting) Einstein's universe in which the Hubble constant is ca. *H*_{o} = 70*k**m* / *s* / *M**p**c* as established by observations, the **Einstein's radius of universe** is ca. 13 bilion light years. The exact number is then *R*_{E} = *c* / *H*_{o}.
