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've million secrets to hide.
Like me there are plenty of other
but we are all empty inside.

Maybe you know, I'm never in 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. :)
