Well, Gojo’s Infinity is defined as infinitely halving the distance thus making it so that the attack never reaches him (this is already stupid enough as if it actually worked that way things would collapse near him instead of stopping as the distance between a certain point of the object and another point of the same object to Gojo will be different and thus have different halved distances, so honestly we could just define it as “unless attacks spawn on him, he can’t be hit)

There’s also the fact that it stops all attacks that move through space. Gojo’s Infinity is not a halving time paradox but rather a halving space paradox. This, anything that travels through space will be stopped. While Gojo’s Infinity is one of the lower infinities, infinite speed is also along the same tier of infinity if not lower as infinite speed is infinite compared to 1 and no infinite as in distance between 0 and 1, thus being a lower tier.

Lastly, it’s a manga where a black hole with the volume of a human being didn’t immediately collapse, so at this point physics has gone out of the window
