[Lilo & Stitch] How does FTL work in this universe?

In the beginning of the documentary, Stitch hits the hyperdrive on his relatively small ship, and a shockwave that seems to be mostly light spreads across the big ship near him, and it looks like the power goes out briefly. 

Does this imply that their hyperdrive has a weird EMP blast? Is the light radiation? Does this mean that hitting FTL effectively creates an nuke?

[](/apathia) The EMP is a form of Cherenkov radiation, essentially FTL's equivalent to a sonic boom. Usually starships take a number of small jumps to reach a distant destination to avoid creating a burst of Cherenkov radiation potent enough to disable a ship, but that crazy trog didn't exactly care about our regulations. Cruisers aren't even supposed to enter FTL except in an emergency!

Also, he took the red one. :(
