However, we can make some educated guesses based on what we know about Gojo's abilities and the laws of physics.
One possibility is that a small and dense domain expansion created by Gojo could create a localized distortion in space-time that could have a variety of effects on the surrounding environment and characters. For example, the distortion could cause objects to be pulled towards or pushed away from the center of the domain, or it could cause time to pass more quickly or slowly within the domain.(獄門彊)
It's also likely that the consequences of using such a technique would be significant and potentially dangerous, both for Gojo himself and for the surrounding environment and characters.(唔知點)
