The cosmological constant is the mathematical description of the energy that drives the ever-accelerating expansion of the ...

Astronomers have long been puzzled by a cosmic mystery: planets orbiting two stars—like Star Wars’ Tatooine—are surprisingly rare, even though they should be common. New research suggests the culprit ...

Gödel found a time-travel solution in General Relativity, revealing spacetime can loop on itself. Gödel discovered a solution to General Relativity that actually permits time travel — no exotic ...

Albert Einstein's general theories of relativity have been used to create tiny microscopic robots that can essentially "swim" ...

Two of the forefathers of quantum theory, Albert Einstein and Niels Bohr, had a famous argument over whether light is a wave ...

Now it seems that wormholes, those shortcut tunnels through time and space that Albert Einstein theorized and that science fiction depicts as portals between two distant galactic points, are at the ...

“With so many unanswered questions, gravity remains one of the most fascinating areas of research,” Patricio Gallardo, one of ...

The quantum revolution in physics — whose 100th anniversary we have just celebrated — taught us that at the most basic level ...

A clear look at how physics defines gravity, from Newton’s force-based model to Einstein’s view of curved spacetime, and why ...

Albert Einstein's words highlight the hidden potential that challenges carry. The quote encourages readers to shift their ...

The cosmological constant has been a problem in physics since Einstein, but new research may show why it takes the value that ...
