In an effort to bring together the domains of gravity and quantum theory, Albert Einstein and Nathan Rosen proposed a striking concept in a 1935 paper. In that work, they described an abstract ...

The puzzle Einstein and Rosen were addressing was never about space travel, but about how quantum fields behave in curved spacetime. I ...

Such a scenario in which the universe is born from inside a wormhole (also called an Einstein-Rosen Bridge) is suggested in a paper from Indiana University theoretical physicist Nikodem Poplawski in ...

Wormholes have long served as science fiction’s favorite shortcut through the cosmos, but a growing body of theoretical physics research suggests they will never function as tunnels. That does not ...
