Alcubierre metric and General Relativity

  1. Jun 18, 2012 #1

    Alcubierre metric:
    [tex]ds^2 = \left( v_s(t)^2 f(r_s(t))^2 -1 \right) \; dt^2 - 2v_s(t)f(r_s(t)) \; dx \; dt + dx^2 + dy^2 + dz^2[/tex]
    What formal conditions are required to verify a valid metric solution of the Einstein field equations?

    How many possible valid metric solutions are there in General Relativity?

    Plug your ansatz in Mathematica and see what the constraints on your parameters are.
