Disclaimer: Unfortunately, my name got lost under some papers and Davies left Moffat in charge of the series, instead of me. I really should take it up with him, the bloody alien conman.
A/N: I loved the bit in the old series where this was explained. It's wonderful to be able to say you understand transdimensional physics. :D

"Oh?"
She then proceeded to explain the theory behind them, simply to wipe that silly expression off his face.
