My (not science) theory is that whatever caused these fundamental forces to appear and separate must be something we can use to cancel them locally, essentially a field around a ship. All we need to do is create a localized and tiny cosmic inflation event to propel a space ship faster than light, until we stop the reaction and it stops moving...
Hey don't laugh, it could work ;p We don't even need to do much, except canceling the fundamental forces in a way that doesn't cause the implosion of the universe...
