Actually we really can't say that. All we can really say is under certain experimental conditions light acts as a particle; and under other conditions light acts as a wave.

Idk.
I do know light is both particle and wave

Actually after watching LOST, that show got me pretty curious about the effects of electromagnetism. I think that powerful enough electromagnets could be the solution to traveling across the universe realistically.
If the solution to the expansion and contraction of space is negative energy/mass due to the casimir effect, then why not try and accelerate that effect with strong electromagnetism?

Shortknight said: Wait I have a question for you guys. Does any matter truely really rest then? Because were always spinning around space constantly. How can it have a rest mass of 0 if we never actually do it? Or can we completely rest?
Shorty
it the case of light it is only said(if we could stop light and make it rest) to have rest mass of 0, as the mass of the light is the kinetic energy itself, and light never is at complete rest it must be said to have mass in the form of energy 
But I have a question for you, this may be far out though. Do we ever completely rest? The world keeps spinning around and around. We never really do completely stop motion. Wouldn't that make our "rested mass" completely based off of the earth? Do we have a different standard of mass in space?
The laws don't change for light in space, so maybe we have to start figuring out our mass in space lol
Im not sure where im going with this, just proding!
Shorty
Edit ive been confusing mass with weight.
I'm 99% sure all particles are moving. The universe supposedly started with the big bang so everything has to be moving. If you launch an object into space it'll keep moving & moving at the same velocity with no added energy until it falls into a gravitational pull. It has the potential to move forever through the space time continuum because space is a vacuum there's no opposing friction from air
Our mass in space is exactly the same as on Earth. Weight is different since it measures the gravitational pull on an object, mass measures the amount of matter in an object.
