Time travel through a wormhole is technically feasible under the rules of theoretical physics—the only catch is that we can only ever go backward. In a blog post for Forbes, astrophysicist Ethan ...

The wormhole problem In principle, building a wormhole is pretty straightforward. According to Einstein's Theory of General Relativity, mass and energy warp the fabric of space-time.

A new paper on a quantum computer simulating a wormhole was picked up by major new outlets, who seemingly jumped to some conclusions in their headlines.

Physicists have used a quantum computer to simulate the first-ever holographic wormhole and transport information through it. The "baby" wormhole, created on Google's Sycamore 2 quantum computer ...
