kind of yes, relatively from an "outside observer" that would be the case.
but if the usual laws of physics apply to that outside "observer" then it will not be able to observe photons from those objects.
the usual assumption is that space is basically infinite but we can only observe our own "observable universe" sphere of it. every point in space has its own universe basically.
