'''Einstein's radius''' is the radius of curvature of stationary (or less properly called "static") Einstein's universe model that was proposed by Einstein in 1917 and later given up after astronomers assumed that the universe might be expanding. Which might have been only an illusion as explained in [[Problems in Cosmology]] and then '''Einstein's redius''' would be about 13 billion light years. The number coming from division of speed of light by [[Hubble constant]].
