Where does Space time come from?

  1. Mar 14, 2014 #1

    What is spacetime?
    Where does it come from?
    It is a kind of matter, energy ...?
    Has power?
    Reacts with something in the neighborhood?
    How is curving?
    When the curving with the electromagnetic field why does not respond to his sign?

    Thank you.
