On May 29, 1919, a total solar eclipse helped to prove Albert Einstein's theory of general relativity. Einstein's theory ...

In 2015, a piece of equipment at an observatory in the US moved one quintillionth (10-18) of a meter. This tiny movement was ...

The discovery in 1998 that the Universe is expanding faster over time shook the foundations of cosmology. This finding ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum ...

Black hole and Big Bang singularities break our best theory of gravity. A trilogy of theorems hints that physicists must go ...

A new study has revealed a novel effect caused by dark photons—hypothetical particles thought to make up a portion of the ...

At Utah State University, researchers are using a radical idea known as the holographic principle to bridge the gap. By ...

Dr Narlikar also played a key role in promoting the steady-state theory of the universe, a notable challenge to the dominant ...

In a new Physical Review Letters study, researchers have successfully followed a gravitational wave's complete journey from ...

In 1987, an enormous blue arc, thought to be hundreds of trillions of miles long, was first considered one of the largest ...

For gravity, Einstein expanded on this work a decade later with his 1915 theory of general relativity. As objects approach the speed of light (approximately 186,282 miles per second or 300,000 km ...

Theories abound, ranging from the influence of a cosmological constant to dynamic dark energy or even tweaks to Einstein’s general relativity. To explore these ideas, researchers rely on vast ...
