The mysterious zones have the power to slow down seismic waves by up to 50 per cent, yet experts don’t know what they’re made of or what role they play.
These strange black holes (figuratively speaking) are located within the Earth’s lower mantle – near the core – and are known as ultra-low velocity zones (ULVZs).

Why all the downvotes? I guess “twilight zones” is a little click baity, but it’s just an article about the little understood geology of Earth’s lower mantle. It’s neat, I think.
I fart glitter with the reasonable take.
