Actual Time Dilation is Dependent on Absolute Velocity It is Impossible for Human Being to Have Time Travel

A description of relative time dilation and absolute time dilation are given and it is pointed out that confusion of the two terms is likely to lead to paradox and it is considered that circular motion velocity to center of a circle is absolute velocity and the time dilation due to absolute velocity is actual dilation---absolute dilation. Absolute dilation is unrelated to any object in relative motion. The time dilation in correlated circular motion has been discussed to conclude that the absolute velocity human being can achieve is very limited; therefore, it is impossible to have time travel.
