Local movement is the cause of mass (ngo quang ha theory)

Physicists have long believed that mass is the reason for particle localization: massless particles always move at velocity c.

However, current physics has not yet determined the cause of mass in elementary particles..

In his book "The Universe is a unified object", author Ngo Quang Ha made a groundbreaking discovery about mass: Energy is motion, and localized motion is the cause of mass in an object..
