I am thinking that if Newton is correct, and he has been up to extremes tested, would particle ever collide if put in motion from a single place.
Considering the earths solar system, with planets moving in syncronized helter-skelter, are we on the outer most reaches of the Universe, where Newton has broken down? Or should Newton be revisted for more distant space exploration?

Newtonian Dynamics and Kinematics work just fine at non-relativistic speeds (up to around 60% or so of lightspeed). And we're not on the 'edge' of the Universe. The Universe has no edge. Every point in the Universe appears to be the 'center' of the Universe. So far as we know, the same laws of physics apply the same way in all parts of the Universe.

Actually, Newton wasn't always correct - when you start moving at speeds close to the speed of light, you have to use relativity instead.
Remember, the universe expanded, not exploded. Not everything was rushing away at light speed.
No, we are not at the edge of the universe. Every point in the universe looks like the middle of the universe. If Newtonian physics didn't work here, we never would have discovered it.

True, every point in the universe looks like the center, because every point IS at the center. However, NOW is the edge of the universe. It's not a where, it's a when. And, it's always now! When you look through a telescope, you look into the past. Now is as far as the universe has gotten...

Newtons theory breaks down at the instant of the big bang.
