one of the great mysteries of physics

ultra high energy cosmic rays. these subatomic particles are going near the speed of light and have macroscopic energies. the question is where do they come from? the Greisen-Zatsepin-Kuzmin limit is basically the max distance they could have come from without interfering with something and slowing down but when we look there is nothing to suggest where they came from.

"it was a subatomic particle with macroscopic kinetic energy equal to that of a baseball (140 g) which is moving at about 27 m/s (60 mph)"

here is a pretty cool list of all the great unsolved problems i just found. have a look Unsolved problems in physics - Wikipedia, the free encyclopedia

This postulate answers each of those in the lists .. and still lets existing physical laws remain intact (for the most part) and then explains why some rules are in error due to intrinsic bias of the observer and anything he builds to observe..

Using this view I can give a rational answer to each of the Unknowns in physics.. But heck I'm but a retired engineer and everyone knows what physicist think of engineers..
