Mass and Time again!

  1. Mar 22, 2012 #1
    I wanted to respond to an older post but it was closed...so perhaps it can be revisited?

    It was asked if someone could shed light on any and all relationships between mass and time? A known theory or even an alternative.

    It was responded to as not knowing of such relation in classical mechanics or quantum mechanics. However in relativity the mass of a particle depends on the location the particle is in a gravitational field and on the particles velocity. These alterations in mass are directly attributable to time dilation effects. i.e. time dilation and mass changes are one in the same phenomena.

    If I had been around at the time...this would have been my post:

    Jayant Narlikar, a student of Fred Hoyle, solved the field equations for particle masses as a function of time.... m=m(t)...which in flat space are simply conservation of energy/momentum which requires that elementary particles to gain mass as m=t^2

    I don't know what you're talking about. To my knowledge the invariant mass of an object in General Relativity is always the same, no matter the velocity it travels at or the gravitational field it is in. The mass of the object determines the amount of curvature that spacetime experiences around it, and thus the gravity around it.
