Thanks Xarthor,

"cannot reach light speed" seems more likely than "reaches infinite mass" so I guess I would agree. I am still sort of confused why a particle couldn't reach light speed, it seems that anything could reach light speed if it gets enough force. The fact that it is at rest or not at rest just seems to alter the amount of force needed. Do you know what I mean?

Also from a limits perspective,
limit of mass, as velocity approaches light is infinity. So thats where I came up with the idea of infinite mass.
