The concept of the Einstein-Rosen bridge is often understood as a cosmic shortcut, akin to a tunnel that links distant points in spacetime. While that image makes for compelling science fiction, a new study shows that it does not match the actual physics behind this concept. Recent research suggests that the original bridge theory was not a wormhole but a mathematical feature of how time is structured. This new realization could help solve a persistent problem in physics. The study, led by Professor Enrique Gaztañaga from the University of Portsmouth, along with K. Sravan Kumar and João Marto, was published...
