When I was five years old, my family moved into a 1930s semi-detached house with a long strip of garden. At the end of the garden was a miniature orchard of eight apple trees the previous owners had ...

Time may seem like a constant force, but according to a new study published on December 1 in The Astronomical Journal, the ...

Gravity and motion make time pass faster on Mars than Earth, reshaping navigation, communication, and future crewed missions.

Learn how Albert Einstein’s theory reveals that time on Mars runs faster than on Earth — and why that tiny shift matters for ...

Physicists hope that understanding the churning region near singularities might help them reconcile gravity and quantum mechanics. At the beginning of time and the center of every black hole lies a ...

It was already a mind-bending shift, last century, to go from Isaac Newton’s absolute space and universal time to Albert Einstein’s four-dimensional space-time, which is dynamic, flexible, sensitive ...

Exploring the BTZ black hole in (2+1)-dimensional gravity took me down a fascinating rabbit hole, connecting ideas I never expected—like black holes and topological phases in quantum matter! When I ...

One way to longer life may be higher gravity—at least for rats. That is the “very tentative suggestion” of experiments performed by NASA Physiologist Jiro Oyama, who has been raising mice and rats ...

There is a glaring gap in our knowledge of the physical world: none of our well-established theories describe gravity’s quantum nature. Yet physicists expect that this quantum nature is essential for ...

Let’s talk about quantum gravity experiments that can be done here on Earth! If we discover how to connect quantum mechanics with general relativity we’ll pretty much win physics. There are multiple ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.
