Thought experiments about Gravitational Waves

  1. Feb 16, 2016 #1
    Imagine a mass that disappeared from space. I know that it is impossible, but imagine it is sucked by a wormhole or it just disapperars.

    Will we detect ONE gravitational wave only? Like a pulse and nothing else?
    Now the other way around. A mass appears from nothing.

    Then we will detect one gravitational wave equal to the previous but in inverse phase (180º)?

    Other question that I have is what happens if a charge appears from nothing in space (thought experiment, of course). The electric field from that charge expands in the form of an electromagnetic wave or simply an expanding electric field?

    Thank you very much!.

    Simon.

    How is this allowed within our current physics?
