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.

The universe rarely fails to amaze. One of its latest surprises—nicknamed the “Einstein zig-zag”—reveals a stunning arrangement of galaxies and a distant quasar. Together, they produce a gravitational ...

On March 15, 2024, a space-based observatory detected bursts of low-energy X-rays from deep in the ancient universe, fluctuating in brightness for over 17 minutes before fading away. About an hour ...

If gravity arises from entropy, scientists could unite Einstein's general relativity with the quantum realm while shedding light on dark matter and dark energy. When you purchase through links on our ...

Over 85 years after it began, the Einstein-Bohr debate remains the most consequential intellectual rivalry in modern science — one that shaped quantum mechanics, redefined human understanding of ...
