Okay, I will now prove that the Abyss has a cosmic scale through evidence, as seen in this context here ↓
As everyone can see, Yogiri opened a countless number of eyes within this dimension, and this is proof that the size of this dimension is extremely large, exceeding the size of the ordinary universe in an uncountable way, because he opened a countless number of these eyes within this dimension.
Look at this calculation to understand ↓
We know that the number of eyes Yogiri opened within this dimension is countless, which means that the size of this dimension far exceeds the size of the ordinary universe to such an extent that we cannot determine its volume with numbers or anything like that.
