Is inter-dimensional travel possible? How do you get an entire city to float? These questions will be answered with quantum physics, revealing the unexpected connection between these two phenomena.

Major spoiler between 10:55 and 12:04. To avoid spoiler, jump to 12:04 The History of Quantum Physics Pt. 2.
