Scientists Create Laser-Cooled Torsional Oscillator for Quantum Gravity Research
The question of whether gravity is a quantum phenomenon has long puzzled physicists, and researchers are now working on experimental approaches to test it. Dongchel Shin, a PhD candidate at MIT’s Mechanical Engineering Department, has recently made progress in this area by demonstrating laser cooling of a centimeter-long torsional oscillator. Torsion pendulums have been used … Read more
