While the concept of time travel has long captured public imagination, modern physics actually approaches time in a much more ...

For more than half a century, the idea that light or radio waves could suddenly reverse in time sounded like a thought experiment, not a laboratory result. Now, a series of meticulous experiments has ...

Chris Impey has received funding from NASA, NSF, Howard Hughes Medical Institute, and the Templeton Foundation. If you look across space with a telescope, you’ll see countless galaxies, most of which ...

The surface of Earth is finite. We can measure it. If it was expanding, then its size would grow with time. And once again, good ol' Earth helps us understand what the universe might be doing beyond ...

Turning a boring 2D photo into a more dynamic, 3D-like viewing experience might sound impossible. But you can do it right from your phone running iOS 26, thanks to Apple's new Spatial Scenes. Apple's ...

New research from UBC Okanagan mathematically demonstrates that the universe cannot be simulated. Using Gödel’s incompleteness theorem, scientists found that reality requires “non-algorithmic ...

Apple has introduced two interesting ways to view photos across its platforms, Spatial Photos and Spatial Scenes, and each adds depth in its own way. Here are the differences and what you need to know ...

Here’s what you’ll learn when you read this story: A new paper adjusts an equation that defines our universe in response to recent new data. The cosmological constant, which describes how our universe ...

It is widely thought that our universe is expanding at an ever-accelerating rate. But could we have that wrong? That is what a group of scientists from South Korea claims, but other scientists have ...

We live at a time of radical uncertainty, with economic stagnation, social upheaval, ideological clashes, violent conflicts, and a global trade war. How to survive the uncertainty and to thrive rather ...

iOS 26 introduced a fresh new look to iPhones with the Liquid Glass design. But it actually isn't the only upgrade that adds visual appeal to your device. One of the other visually interesting ...
