# New Discoveries About Hubble's Law

If we assume that the Universe is spherical and in addition to increasing its radius, it also has a rotational motion around its axis, its velocity equations can be written as follows: Total Velocity of Universe equal Linear Velocity plus Rotational Velocity. On the other hand, Hubble's law describes the velocity of a galaxy in the Universe. In this paper, with the mentioned assumption and comparing it with Hubble's law we are going to justify the sphericity and the rotation of the Universe and we will calculate the real radius of the Universe and its actual rotational velocity.
