Hyperloop is based on three scientific principles.
Magnetism: The moving shuttle would be magnetically suspended within the vacuum tube without touching any part of the tunnel while it is traveling. So no contact, no friction.
Vacuum: The Hyperloop transport tube would be airless to virtually eradicate any air resistance.
Inertia: The Hyperloop technology uses nearly linear channels so the turns would be less sharp or there would be no turns at all. This ensures continuity of momentum without sharp turning points which serve as intermittent speed breakers.
All of the above mentioned factors give Hyperloop technology a great advantage over other four modes of transports, including air travel.
