We've already established that the DET idea also requires an additional "as-yet-unheard-of mechanism" in order for it to work (i.e. explain what we see).
All right, then your theory requires the creation of TWO additional "as-yet-unheard-of-mechanisms"... the cause of the shockrings AND the non-DET abilities of the superlaser.
I've asked you several times in the last thread, and you have been unable to answer why your theory explains the shockrings any better than the DET theory... you simply reasserted that "It caused it somehow".
In DET, it is unexplainable. In mine, it is at least a plausible outcome of the mechanism.
No, it is not. Your theory absolutely fails to explain why such "rings" would be created. In either theory, a shockwave would appear as a sphere. Furthermore, using the existence of the shockrings as proof of your non-DET theory also fails due to the two instances in which the superlaser fails to reproduce the same effect - a primary explosion and a secondary explosion - when used against starships.
I'm intrigued by your ability to predict that my theory suggests a sphere, when I disagree and the theory itself makes no such prediction.
ANY explosive shockwave creates a sphere. Are you contending, then that Alderaan didn't explode?
Obviously, there was a similar mechanism at work in the destruction of the planet and the destruction of the two Death Stars (although an odd mechanism, as the ring is off-axis in the DS1 explosion, but not the second), but not the destruction of the two Mon Cal cruisers in ROTJ.
The problem is that your "matter-eating" theory does not explain WHY such a ring would occur. Admittedly, neither does the DET theory, although there are numerous suppositions.
Except, of course, those pesky canon visuals.
You have never adequately explained HOW the canon visuals disprove the DET theory... you have simply continued to assert that it does.
Argumentum ad infinitum, a debating fallacy.
