Science Nugget: 3⚛

Europe and Asia have bullet trains that travel at a fantastic pace, reaching over 320 km/h. However, commercial maglev (for magnetic levitation) trains can operate even faster. Maglev trains use magnets that repel another set of electrically charged magnets on the track, causing the train to float several centimetres in the air. The first opened in Shanghai, China, in 2004 and reached speeds of over 340 km/h; since then maglev technology has only improved, leading to even more incredible speeds.

‘Wait! So is this a hypothesis, a theory, or a fact?’
