    I know you can see the laser beam fired from a green laser pointer in the dark withut smoke or dust to reflect light to your eyes. Am I right in assuming the green light is just able to bounce of smaller particles than the red light or would you also be able to see the green laser light in space?

    I don't think you would since the purpose of a laser is to get the light going only in one direction, if you could see it it means light is dispersing in multiple directions

    You are seeing the light being scattered off of dust particles in the air.

    In space or other vacuum you would not see the beam at all, regardless of its color.
