Riddle (Gravity)

Born at Creation
Every particle to every particle
No-one wants to be alone
Force of darkness
Strange attraction
Feel me
I'm an extraordinary power.
Obeyed by moons and worlds
I can bend anything, even light
Travel through everything, even lead
Weak at a distance, strong up close
Everybody knows me
Dragging you down
Relentless
Irresistible
Strongest and strangest
At the bottom of holes.
Look closer!
I escape from everywhere!
An incredible force
Flouted by bubbles, butterflies and bees
Immortal, invisible
Re-arranging the stars
I curve space
Slow time
Dig holes
All over the universe.
What am I?
