Random Riddle: Smithereens

I hover out there in darkness, unseen.
I will shred things to pieces ’till they’re just smithereens.
I might serve as a gateway to places unspoken,
Yet I’m sealed off to man, forever unbroken.
I twist and distort, only darkness escapes,
I destroy all I find
Whatever I take.
