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

To reach this conclusion, the researchers examined the most basic form of entanglement between identical particles using the concept of nonlocality introduced by physicist John Bell. While ...

The research team used two distributed sensors and leveraged two quantum resources for increasing detection sensitivity: ...

Add Yahoo as a preferred source to see more of our stories on Google. Most people have never heard of vacuum decay, but if it happened it would be the biggest natural disaster in the universe. Sure, ...

If true, the idea would blow past one of physics’ most sacred limits: that parallel versions of reality can never talk to ...

"We have long treated the Planck scale like a blurry limit," said Kulkarni. "But if you treat space as an information storage medium, geometry dictates a specific packing efficiency. The universe has ...

Nearly 50 years ago, physicists floated a bold idea: our universe might be stuck in a false vacuum. This state feels stable, but deep down, it's not. Over enormous timescales, it could suddenly tip ...

We’ve been told by science that the universe is expanding relentlessly, driven by a mysterious force called dark energy.

For decades, physicists have faced one of science’s greatest puzzles: merging quantum mechanics, which describes tiny particles, with general relativity, which explains the universe’s vast structures.

Quantum annealer has simulated the fundamental process of false vacuum decay, opening the window to the understanding of interactions between true vacuum bubbles. Credit: Professor Zlatko Papic / ...
