Other mistake: When Mr. Peabody is fencing with Robespierre in the sewer, the sword goes flying up and causes the manhole cover to go flying up too. But then the manhole cover falls through the opening to land on Robespierre. There's no way a round manhole cover can fall through its own opening.

Taxi Driver: Hey, Einstein, it's a red light.
Albert Einstein: Hey, I'm walking here.
Answer: By travelling to the future, as it approached the speed of light, the WABAC machine generated a gravitational field equal and opposite to the rip in the space-time continuum and cancelled the rip out - a combination of the suggestions of Sherman, Da Vinci, Einstein and Newton.
