Factual error: The Doctor wonders how the creature can survive three billion electron volts. This is about 0.0000000006 joules. A baseball traveling a 2 miles per hour is one joule. It would take a lot more than three billion electron volts. It would take about 60 billion billion electron volts just to supply one joule. The energy hitting the monster was less than that supplied by running into a gnat.
