Expanding? Is the infinite universe expanding? Into what?
The sound of galloping hooves does NOT mean the zebras are stampeding.
Given a finite number of moving objects randomly vectored at random velocities within a finite volume, eventually all collisions which could occur WILL occur - within a finite period of time. Many of those collisions may occur outside of the original volume, but they will still take place within a finite period and within a finite distance. Once all collisions have occurred, all objects will eventually reach the boundary of the initial volume and except for those very few which may be moving at exactly the same velocity in precisely parallel paths,
they will all be moving away from each other.
There is more than one explanation for the 'big bang' observations of astronomers. I concede the possibility of some local cosmic engine reaching critical mass and exploding, but it occurred in that infinitesimal portion of the universe visible to our limited technology.
There is more to the universe than meets the telescope - x-ray, radio or otherwise.
