I'm surprised they put so much attention into black hole physics in this episode, considering the previous episode's glaring scientific plothole (Earth's atmosphere has no nitrogen?). When the black hole started, the special effects gave attention to the pitch of sound declining and everything slowing down in proximity to the event horizon. And how the black hole's gravity gradually ripped apart the city, sucked up the ocean, and then disintegrated the planet.

The funny thing is, the characters who died being sucked into the black hole probably never actually died&mdash;time slowed down for them until they stopped entirely, frozen in time and place. I mean, of course from the outside they were destroyed, but time stops inside the singularity. Not that it really matters, since nothing can escape the singularity except Hawking radiation.

...and that is officially where I start overthinking the situation. :) Still, impressive scientific detail. There is one oversight though&mdash;a black hole doesn't actually look like a "hole", as if it were a wormhole or portal.  But this was still impressive.
