This puzzle is known as the problem of time, and it remains one of the most persistent obstacles to a unified theory of ...

The geometry of spacetime forms the very foundation of modern gravitational theory, where the elegant interplay between curvature and matter is described by Einstein’s field equations. In this ...

Gravity has become an unlikely viral villain, blamed for an imagined global blackout in which the planet briefly lets go of ...

Independent researcher and CEO of IDrive Inc., Raghu Kulkarni, has unveiled a groundbreaking framework for understanding the universe: the Selection-Stitch Model (SSM). The model suggests that ...

In 1905, Albert Einstein revolutionized physics by demonstrating that time is not absolute but relative to the observer's ...

The original version of this story appeared in Quanta Magazine. Two blind spots torture physicists: the birth of the universe and the center of a black hole. The former may feel like a moment in time ...

Intuitively, we know what time is, but try to explain it, and we end up tying our minds in knots. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works.

A fringe new theory suggests that time is the fundamental structure of the physical universe, and space is merely a byproduct. According to Gunther Kletetschka, a geologist — not a physicist, you’ll ...

One of the most awkward parts of writing a book is that, eventually, authors have to ask people for “blurbs” – the endorsements that you see on the cover of a book, encouraging you to buy it. I am now ...

The first time you experience weightlessness in space, Tom Marshburn told me, all the noise and pressure of launch suddenly disappear. One moment, the roar of engines shakes every bone in your body; ...

For example, a Convolutional Neural Network (CNN) trained on thousands of radar echoes can recognize the unique spatial signature of a small metallic fragment, even when its signal is partially masked ...
