"WebThe Virial Theorem . The asymptotic average of the derivative of a bounded function is zero. (Intuitively, if you drive around your parking lot for a long time, your average velocity approaches zero, because as time elapses your net distance traveled does not increase.) Formally this can be expressed by noting that, for any constant k and function r(t) … " - The virial theorem

As it turns out, MV is nearly 20−30 times greater than M and this diﬀerence is known as the virial mass discrepancy [1]. The prime tool in dealing with the above discrepancy is to postulate dark matter. boyd handley attorney
