Physicists are scrambling to understand why dark energy is weakening. In a surprising twist, we must now reconsider the ...

Michael S Turner argues that the next breakthrough in particle physics and cosmology may be just around the corner.

Ripples in the fabric of space-time called gravitational waves may be the key to solving the Hubble tension — one of the biggest nagging problems in physics.

Astronomers have long known the universe is expanding—but exactly how fast remains one of the biggest mysteries in cosmology. Different techniques for measuring the Hubble constant stubbornly disagree ...

From Leonardo’s notebooks to neural networks, the tools of intelligence have evolved, but the human impulse behind them remains the same Suhaib Bakshi When a student today asks an artificial ...

Vijay Balasubramanian (University of Pennsylvania) emphasised that the challenge is not only reproducing the familiar area law – which links entropy to the area of the event horizon – but also ...

An international research team has found that the Milky Way and its galactic neighbors appear to sit inside a vast, flat concentration of dark matter, a structure stretching roughly 10 megaparsecs and ...

Two new studies have measured the expansion of the universe in our immediate cosmic neighborhood using a novel method that ...
