I already addressed my concerns recently with several of the special attack animations. The Big Bang Challenge's stars appear to be flickering, which is uncharacteristic of natural stars, which calls into question their legitimacy, along with that of Cosmic Flare.
In addition to this, the Metaverse, as previously stated is reflective of a person's cognition. The Metaverse is essentially a malleable world that appears exactly alike our own except when people with distorted desires distort the Metaverse. In Okumura's case, he viewed Okumura Foods as a spaceport. However, I skeptical of immediately granting the stars witnessed in there legitimacy either, as a Palace is a reflective of the person's thoughts and the Palace appears in the same location as it appears in reality. For instance, Sae sees the court house as a casino, but the surrounding areas are left untouched. With Okumura, the surrounding city around Okumura Foods could simply be representative of the outer space we see, meaning it isn't actually filled with stars and isn't actually that large. When they exited the Metaverse from Okumura's Palace, they appeared in the city surrounding Okumura Foods, meaning the surrounding city is what became the outer space we see, and would only be as large as the city. Makoto even states that the surrounding space isn't a true vacuum, only adding to my suspicion. I hope this all makes any lick of sense.
Granted, Futaba's Palace was a massive desert despite her Palace and distortion only be her house, so maybe I'm just overthinking things and everything I wrote was dumb. The Morning Star feat is fine, however.
Though I do hope we can somehow legitmize these feats. I need meh galaxy-universal P5 cast.
