Normally, two closely spaced surfaces stick together due to the quantum Casimir effect. But scientists found a way to turn this attraction into repulsion by adding a magnetic fluid—and made a tiny plate levitate in the air without support. Fine-tuning the materials paves the way for microdevices where parts are held by the quantum field.
🎯 The Casimir effect was predicted by Dutch physicist Hendrik Casimir in 1948 while studying the forces between glue molecules.
🎬 The technology resembles sci-fi hoverboards floating without wheels or motors, but instead of magic—it’s quantum glue.
