Einstein’s Theory of General Relativity is currently our best approximation of how the universe ticks. But there are holes.

The universe’s accelerating expansion has long puzzled physicists. For decades, dark energy, an unseen force thought to make ...

Scientists have determined a way to measure gravity on microscopic levels, perhaps bringing them closer to forming a theory of "quantum gravity" and to solving some major cosmic mysteries. Quantum ...

Wormholes are often imagined as tunnels through space or time—shortcuts across the universe. But this image rests on a ...

To progress to the next level in understanding reality, we need to combine quantum mechanics and Einstein’s general ...

There’s an adage coined by [Ian Betteridge] that any headline ending in a question mark can be answered by the word “No”.

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

The accelerating expansion of the universe is usually explained by an invisible force known as dark energy. But a new study ...

The first image of a black hole, captured in 2019, has revealed more support for Albert Einstein's theory of general relativity. The new finding has suggested his theory is now 500 times harder to ...

Quantum Gravity and General Relativity represent two foundational yet traditionally disparate pillars of modern physics. General Relativity, Einstein’s seminal theory, elegantly encapsulates ...

Newton's theory of gravity posited instantaneous gravitational attraction, successfully predicting planetary orbits. Einstein's special relativity challenged this, necessitating the development of ...

China has quietly solved a problem that only becomes obvious once you try to live and work off-world: clocks on the moon do ...
