Hi Greg! I had some questions about the Cosmic Treadmill in Young Justice.

1) What is it exactly and how does it work? In the comics it's used by speedsters to time travel, but that doesn't seem to be the case here. Am I correct to assume it's primary/only function was to super-charge Bio-Ship so she could fly faster?

2) Why did it take Bart, Saturn Girl and Chameleon Boy over three months to collect and assemble materials for it?

3) Who's idea was it to build a Cosmic Treadmill specifically? Bart's or the Legionnaires'? And where did the idea come from?
