Second, and more on-topic, I don't agree with your claim that the Distortion World is made of antimatter. As you yourself said, if the Distortion World were made of antimatter, you'd explode when you walk through it (like you do in DPP). Furthermore, antimatter doesn't cause the spatial anomalies seen in the Distortion World, which seems to have a very erratic force of gravity (and which allegedly has no flow of time, but this claim is absolute nonsense in both scientific terms and in-game ones).
The Distortion World seems much more likely to be made of normal clumps of matter arranged in some non-Euclidean way due to Giratina's original designation as a dimensional entity rather than an antimatter-themed one. The differences in Giratina's forms could be tied to this as well: Origin Giratina is stated to be able to effortlessly move through dimensions, while Altered Giratina doesn't have this ability due to the higher gravity of the normal world. Why does this matter to a godlike entity? Well, gravity is defined in physics as a curvature of spacetime. The Distortion World seems to have an earthlike gravity, but it's all broken up across floating chunks. This makes no sense: The chunks should either have too little gravity to stand on (but still enough to eventually all clump together), or they should each be so dense that there's no way they'd all still be separate (Also, they'd probably crush you if you tried.) after however many eons they've been in the Distortion World. So, perhaps the random arrangement of matter in the Distortion World is due to it all being part of the same multidimensional 'planet' overall, but because we can't see more than 3 dimensions, parts of it appear to be missing - the parts that Origin Giratina can move through. The normal world, on the other hand, has only 3 dimensions of space, so there's nothing for Origin Giratina to move through. Its Origin Forme is rendered useless, so it switches to its Altered Forme, which is much better-suited for walking/flying.
...It's admittedly not a much better hypothesis, but it doesn't break the laws of physics quite as blatantly.
