The geoid (the surface of equal gravitational potential of a hypothetical ocean at rest) serves as the classical reference ...

That the universe is expanding has been known for almost a hundred years now, but how fast? The exact rate of that expansion ...

Forte and colleagues now believe Antarctica’s gravity hole was weaker before eventually intensifying around 30 to 50 million ...

Antarctica is home to many mysteries, but one of the strangest is an enormous 'gravity hole' deep beneath the ice. Now, scientists know why it is there.

New data from major dark-energy observatories suggest the universe may not expand forever after all. A Cornell physicist calculates that the cosmos is heading toward a dramatic reversal: after ...

The mystery of dark matter—unseen, pervasive, and essential in standard cosmology—has loomed over physics for decades. In new research, I explore a different possibility: Rather than postulating new ...

The supernova SN 2025wny is hopelessly far, lying approximately 10 billion light-years from Earth. Normally, this would make it impossible for astronomers to detect. But one team got lucky. While ...

Timing delays in quasar light bent by massive galaxies offer a fresh way to measure the universe’s expansion, and the results deepen the rift between early- and late-universe estimates. This growing ...

James is a published author with multiple pop-history and science books to his name. He specializes in history, space, strange science, and anything out of the ordinary.View full profile James is a ...

In a dramatic twist on classical physics, scientists have cooled a mirror to near absolute zero with lasers to see if gravity might be quantum. This breakthrough could reshape how we understand the ...
