Developed in 1915, general relativity suggests that gravity arises because bodies with mass cause the fabric of spacetime (the four-dimensional unification of space and time) to warp. The greater ...

Einstein's theory of general relativity predicts gravitational memory, where space-time retains imprints from passing gravitational waves. Researchers are exploring if the cosmic microwave ...

Scientists are exploring a new way to test one of Einstein’s theories—an effect called gravitational wave memory, which could leave a permanent mark on space. The search for this hidden imprint has ...

March 8, 2025: Our weekly roundup of the latest science in the news, as well as a few fascinating articles to keep you entertained over the weekend.

So, where does the arrow of time come from? A growing group of physicists believe that it originates in the force of gravity itself. But to get there requires a radical reshaping of Einstein’s ...

and then by predicting a small cosmological constant (which explains how much and how fast the universe is expanding). The new theory also incorporates a G-field, or gravitational field.

Harvard astrophysicist Dr. Willie Soon has suggested that a mathematical formula could prove God's existence. By examining cosmic constants and the fine-tuning argument, the theory posits that the ...

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 ...

The study, titled "Gravity from Entropy," introduces a novel ... positive cosmological constant—a value that aligns with experimental observations of the universe's accelerated expansion much ...

There is no place like Hollywood. And there is no opening like a “Wizard of Oz”-themed medley from “Wicked” stars Ariana Grande and Cynthia Erivo. Grande opened the 97th Academy Awards by ...
