Is it theoretically possible that the metric in the whole universe would be described
by Kruskal extension of Schwarzschild solution of Einstein equation and in the universe
would be no matter at all (vaccum solution everywhere).
What's the interpretation of parameter m characterising Schwarzschild solution in this case?
Does the matter need to be somewhere in the universe in case of this solution
because we don't want to have white hole? Are there also other arguments for
placing matter in some regions.
What about the statement that matter (stress energy tensor) is the source of
gravitational field. Are nonflat global solution of vacuum Einstein equation acceptable
in whole universe (theoretically) or if there was vacuum everywhere in the universe
it would have to be flat.
Thanks.
