You get an infinite loop and the universe crashes

[TheMarcaxe]

Superconductivity is useful, but isn't a requirement of keeping the train on the track. you'd just need an awful lot of cooling.

superconductivity allows for some levitation and propulsion. superconductivity is used to to propel the molecules on the large hadron collider as well as some trains right now, im pretty sure. Micho Kaku talks about it in his video "the quantum revolution"
