So can anyone answer my second question?

The particles, say the ones they send around a collider, go near the speed of light from what I hear. So are those particles actually moving slower because their time is moving slower as seen from our stationary observation?
If we send a particle at 0.99c then we measure it moving at 0.99c, not moving slow. If you had a clock on those particles and could observer it the clock would seem to be running slow. If you had a space ship that could travel 0.99c and went for a trip when you got back more time would have passed on Earth than on your ship. This is called the Twin Paradox.
