While this may complicate the quest for a clear experimental signature of quantum gravity, it does not render such tests useless. According to the research team, both classical and quantum models of ...

Unifying gravity and quantum theory remains a significant goal in modern physics. Despite the success in unifying all other ...

Gravity is the most familiar of nature’s forces. It keeps our feet planted on the ground and dictates the movements of ...

Abstract: Low-gravity multiphase flows play a central role in an increasing number of space systems, ranging from propellant management and thermal control to life support and food processing. Over ...

Discovering a machine that could somehow produce thrust without releasing propellant would be a game-changer for human space travel. There’s just one problem—such a device would defy the laws of ...
