Riddle with heavy answer

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. :)
