Void Ghidorah's Blackholes are called a Singularity. A Blackhole has a singularity, the singularity has an infinite mass and density, the gravitational pressure is infinite and space-time bends infinitely, it break downs space-time and the laws of physics and they cease to exist.

Void Ghidorah defies this universes laws of physics, which put him above the universe itself.

(Low Complex Multiversal)
Void Ghidorah uses Supergravity, which can reach 4D to 11D, but is 5D due to Void transcending a 4D universe.
Godzilla Earth endures 3 of Void Ghidorah's heads which are more massive than the Singularity of a Blackhole. He's tanking Infinite 3D - 4D 3x at once. This puts him 3 layers of Infinity into 3D to 4D.
