Let me start with the idea: it kind of follows the current Hollywood doomsday trend. We got a hypothetical White Hole (the opposite of a Black Hole) which shoots chunks of ultra-high density matter into space - really good SciFi idea.
The science: You would think that an object the size of a tennis ball and the mass of a few hundred planets would have a profound gravitational effect while passing through the Solar System and through Earth for that matter. They never mention that. I mean, when you hear the words "the mass of a few hundred planets" the first thing you mind takes you is gravity. They were able to use cell phones and computers with very few problems although there were magnetic storms above them. The communications and power supply lines were almost unaffected.
