Ok, you hacked my other riddles pretty quickly, but this one is meant to give you heat.. There you go:


    I am born from the death of my mother
    and I have millions of secrets to hide.
    Like me there are plenty of others
    but we are all empty inside.
    
    Maybe you know, I'm never in a hurry
    due to my origin sublime.
    At the same time, I am always hungry,
    not for knowledge,
    but for time.


Good luck this time. And btw, just one single word I skipped in the last sentence can point you immediately to the right answer. :)
