In moments of emergency, super-concentration, or meditation, people report moments of “time expansion experiences,” or ...

NASA's GRACE satellite detected a large gravity anomaly over the Atlantic Ocean. Meanwhile, Earth-based observatories saw a ...

Space and time seem like two completely different ideas, but Einstein showed they are interlinked in what is known as ...

Whether space-time exists should neither be controversial nor even conceptually challenging, given the definitions of “space-time,” “events” and “instants.” The id ...

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 ...

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 ...

“You can’t beat the view,” astronaut George Clooney says to NASA scientist Sandra Bullock as they gaze from their space station at the Earth, 372 miles below. Gravity enjoyed a similarly lofty view ...

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.

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 ...

If you wave your hand in front of your face, you won’t notice anything particularly interesting. Perhaps a gentle waft of air against your cheek – that’s about it. No epiphany. No major sign that ...
