LITTLE ROCK — Imagine that you’re a science-fiction writer on a tight schedule. You’d like to play in the vast expanses of the universe, but you have too much scientific integrity to conjure up a warp ...

An Einstein-Rosen bridge is a hypothetical, yet unproven, feature of spacetime. In theory, these so-called wormholes provide a shortcut through the Universe to connect two separate points in ...

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 ...
