How come sub-atomic particles aren't affected by the vacuum around them

    Why aren't sub-atomic particles (electrons, protons, neutrons) affected by the vacuum around them. Why aren't they tugged off course like air in space

    I think you have a small misunderstanding about vacuum.
    Vacuum doesn't suck - what happens with say a vacuum cleaner (or a pump) is that you have less air on the inside than outside and so air moves towards the vacuuum simply out of randomly filling the spaces.
    It's like having a crowd of people in a small room and opening the door - they will gradualy fill both rooms - but the empty room isn't pulling them
