"Confirmation of 'Second Sound' Phenomenon by Scientists"
Scientists at MIT have successfully captured the movement of pure heat, known as "second sound," in exotic superfluid quantum gases using a new method of thermography. This behavior, where heat propagates as a wave instead of spreading out, has been observed before but never imaged. The study, published in the journal Science, utilized a novel technique involving radio frequencies to track subatomic particles and capture the second sound in action. Understanding the properties of second-wave movement in superfluids could have implications for high-temperature superconductors and the physics of neutron stars.
