Typically, when an object heats up, the warmth spreads outwards and gradually disperses. However, this conventional behavior doesn't apply to superfluid quantum gases. For the first time, researchers from MIT have managed to capture images of how heat moves in a wavelike manner, referred to as "second sound," through this unusual liquid. Grasping this dynamic might aid in unraveling mysteries surrounding high-temperature superconductors and neutron stars. In the realm of ordinary, day-to-day substances, heat generally disperses from a specific origin point. Toss a glowing ember into a container of water, and that liquid will gradually increase in temperature before its warmth ultimately fades away. However, the world is home to many unusual, rare substances that do not exactly adhere to these thermal guidelines. Rather than dispersing as anticipated, these superfluid quantum gases exhibit "heat sloshing" from side to side; this ...

Theoretical physicists have put forward a possible answer to one of the most perplexing issues in contemporary physics: the black hole singularity paradox. By altering Einstein's theory of general relativity. relativity The researchers propose in a new study that the center of a black hole, characterized by infinite curvature, might instead be a highly curved yet smooth area of spacetime. "Singularities are areas in the universe where space, time, and matter are compressed and elongated into nothingness," according to study co-author. Robie Hennigar A postdoctoral researcher at Durham University in the U.K., communicated with Live Science through an email stating, “This is a significant issue because if singularities actually existed within our universe, it would lead to major problems for scientific understanding.” We couldn't continue using the equations anymore. physics To forecast the future using the past and present," he went on to say. ...
