Dark energy, the mysterious force thought to be driving the ever-faster expansion of the universe, appears to be changing over time, according to new observations released Wednesday. If dark energy is ...

Albert Einstein is arguably the most influential scientist of the 20th century. His general theory of relativity changed our understanding of space and time, becoming one of the two pillars of ...

1905 is referred to as the “miracle year” by physicists. In that one year, Albert Einstein published four papers that laid the foundations of modern physics. One of the major breakthroughs ...

In 1905, Albert Einstein shook up physics by proposing that light wasn’t just a wave, but it could also behave like a collection of particles (which were later called photons). This outrageous idea, ...

WASHINGTON, DC - NOVEMBER 08: A Beaver Blood Moon Lunar Eclipse is seen setting behind the U.S. ... More Capitol Building on Election Day on Tuesday, Nov. 8, 2022 in Washington, DC. (Kent ...

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. A new recipe for gravity could help ...

Quantum entanglement is the cornerstone of practical applications for quantum mechanics. A new study found an easier method for establishing entangled photons, thanks to the help of an AI tool ...

The reconciliation of general relativity and quantum mechanics is one of the biggest challenges in science, one that continues to elude us. Now, a new study by Anjun Chu and colleagues has ...

Einstein's theory of general relativity suggests that the "memory" of ancient events, such as black hole mergers, may be etched into the fabric of space-time by gravitational waves. New research ...

Astronomers have identified the closest ever Einstein ring, a rare phenomenon where light from a further-off galaxy is bent by the gravity of a galaxy closer to Earth. The ring was previously ...
