Usage examples of tweedles.

Within this region, space and time recoupled and contracted inward with the imploding core to simulate for an instant the bizarre, inverted conditions of an antiuniverse, and in that instant a large portion of the tweedles liberated in the process transformed into antitweedles which, under the prevailing high-energy conditions, combined preferentially into antiquarks and antileptons rather than radiation.

And it was the duality of universes, each exhibiting a spacetime decomposed into two discrete dimensions, which gave rise to the two-way duality manifested by tweedles and antitweedles: Dums, dees, antidums, and antidees were simply spacelike, timelike, antispacelike, and antitimelike projections of the same fundamental entity existing in the timeless, spaceless domain of tweedlespace.

It followed that “antitweedles” didn’t necessarily give an antiparticle, and tweedles didn’t always make a particle.

There were grounds for supposing that if an expanding nodule of disentangled space and time were introduced arbitrarily through some mechanism—pictured by some people as a bubble appearing in soda water, although this wasn’t really accurate—the reduced “pressure” inside the bubble would trigger the condensation of raw tweedlestuff out of “tweedlespace” as an explosion of tweedles and antitweedles, the tweedles preserving the “timelike” aspect, and the antitweedles the “antitimelike” aspect of the timeless domain from which they originated.

The way to obtain antimatter, they therefore reasoned, would be to make a small part of the universe look like an antiuniverse so that tweedlespace could be “fooled” into projecting antitweedles instead of tweedles into it.

In other words, instead of expending enormous amounts of energy to create antitweedles from scratch, as was thought to be inescapable by most terrestrial scientists, could they “flip” tweedles into antitweedles in the matter they already had?
