Since relativity allows objects to move faster than light (relative to each other and including the expansion of space/time) is it possible that some dark matter is ordinary matter that is moving away from us faster than the speed of light? This matter would not be visible to us, but it's gravitational effects could still impact objects that are visible to us. Thanks.
