Chinese Rover Uncovers Evidence Supporting Theory of a Vast Ancient Ocean on Mars

China’s Zhurong rover has discovered formations on Mars that could signal the remnants of a once vast ocean. Landing in the Utopia Planitia region, the rover identified formations commonly linked to past water presence, supporting the theory that Mars was once home to a massive body of water. While the findings do not offer definitive proof, they bring scientists closer to understanding Mars' history and its potential to support life.

Can we solve quantum theory’s biggest problem by redefining reality?

With its particles in two places at once, quantum theory strains our common sense notions of how the universe should work. But one group of physicists says we can get reality back if we just redefine its foundations

How indefinite causality could lead us to a theory of quantum gravity

Experiments show that effect doesn’t always follow cause in the weird world of subatomic particles, offering fresh clues about the quantum origins of space-time

New spin on quantum theory forces rethink of a fundamental physics law

In the quantum realm, a particle’s properties can be separate from the particle itself, including its angular momentum – which could require a rethinking of fundamental laws

Quantum theory is challenging long-standing ideas about entropy

A mathematical study finds that three definitions of what it means for entropy to increase, which have previously been considered equivalent, can produce different results in the quantum realm
