Physicists Caught Sound Moving at Two Different Speeds in 3D Quantum Gas

Posted by in categories: energy, quantum physics

After previously studying the phenomena of two sound waves in quantum liquids, scientists have now observed sound moving at two different speeds in a quantum gas.

If you were somehow immersed in the three-dimensional gas used for this study, you would hear every sound twice: each individual sound carried by two different sound waves moving at two different speeds.

This is an important development in the field of superfluidity – fluids with no viscosity that can flow without any loss of energy.

    I have been intrigued by quantum anything lately. My favorite is quantum entanglement. Thank you for the reaches of study that help explain a lot of what humanity has questioned for so long. It never gets old.
