[Note: Don's "explanation," if you can call it that, probably doesn't even merit this reply. Gadfly, bite me now!]

Okay, so you toss out Newton's third law with

The super force at the boundary of the universe is not a wall, it is simply where the laws of nature cease to exist, it is where space ends. Nothing can penetrate the boundary - not even the full force of a galaxy crashing into it. Beyond the boundary there are no laws to guide matter or energy, therefore they cannot exist in this lawless void.

because the Super Force is exerted by nothing, and thus there is an action without an equal and opposite reaction.

Since the third law leads directly to the conservation of momentum, this proposal also tosses out a fundamental conservation law.

You also postulate an instantaneous effect due to a cause tens of billions of light years away by writing

the matter spontaneously appears in the central region at the same time as the matter is absorbed at the boundary

Not only does that violate causality, but it also reinforces one question you didn't answer, namely what evidence do you have that this central region exists (counter to the basic premise of Relativity)?

You didn't provide anything that describes the mathematical properties of the Super Force or how we can detect it in the universe. The expansion and acceleration of that expansion have explanations that fit within the conventions of Relativity, so you can't claim those phenomena as evidence that the Super Force provides a better explanation.

In short, your response is so far from sufficient that I am unwilling to continue this discussion. Call me a stick-in-the-mud if you will, but I need more than platitudes to overthrow conservation of momentum, causality, and relativity, not to mention centuries of observational and experimental evidence that support those ideas.

Show evidence and provide the missing specifics of your theory. Otherwise its claims can only be regarded as outlandish at best and "crackpot" at worst.

And now, having drawn some more of Don's more outrageous assertions into the light, I leave it to others to defend them or comment further. My work is done here, as "Gadfly" might say.

[Final note: I just noticed Don has replied to Anonymous with an answer that includes a rejection of entropy. There goes thermodynamics and information theory out the window as well! That response also indicates that we live in the central region of the universe, yet Don has made no suggestion of how we can detect all the massless matter that is suddenly appearing here. This has now reached the point where I officially declare this a waste of everybody's time, and I am only posting this because it is already written.

If you've read this far, what is wrong with you? :) You'd be far better off discovering my history of physics in the Twentieth Century, Physics: Decade by Decade (Facts on File, 2007).]
