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 ...

Cosmology and quantum physics both offer tantalizing possibilities that we inhabit just one reality among many. But testing that idea is challenging.

Repulsive gravity at the quantum scale would have flattened out inhomogeneities in the early universe First light The cosmic microwave background, as imaged by the European Space Agency’s Planck ...

Even given a set of possible quantum states for our cosmos, it's impossible for us to determine which one of them is correct ...

For more than a century, physics has been built on two great theories. Einstein's general relativity explains gravity as the bending of space and time. Subscribe to our newsletter for the latest ...

A recent study proposes that gravity, the force shaping galaxies and anchoring planets, might not be fundamental after all. Instead, it could arise from entropy, a measure of disorder. The theory, ...

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.

I've long been fascinated by the fundamental mystery of our universe's origin. In my work, I explore an alternative to the traditional singularity-based models of cosmology. Instead of a universe ...

In 2022 three scientists won the Nobel Prize in Physics for proving something astonishing: the universe is not locally real. In other words, particles don’t have fixed properties until they are ...

Add Yahoo as a preferred source to see more of our stories on Google. A team of researchers has developed a new quantum dilution refrigerator that could revolutionize quantum computing research. Able ...

Time feels like the most basic feature of reality. Seconds tick, days pass and everything from planetary motion to human memory seems to unfold along a single, irreversible direction. We are born and ...

The way time ticks forward in our universe has long stumped physicists. Now, a new set of tools from entangled atoms to black ...
