Wormholes are often imagined as tunnels through space or time—shortcuts across the universe. But this image rests on a ...

To progress to the next level in understanding reality, we need to combine quantum mechanics and Einstein’s general ...

The universe’s accelerating expansion has long puzzled physicists. For decades, dark energy, an unseen force thought to make ...

Our universe plays by certain rules, which originate from different branches of physics. But sometimes the rules seem ...

For decades, quantum physics and general relativity have stood as two powerful but separate theories. Quantum physics explains the behavior of tiny particles like atoms and photons. General relativity ...

Physicists have long treated space and time as the stage on which quantum particles perform, not as actors in the drama ...

Quantum mechanics and relativity are the two pillars of modern physics. However, for over a century, their treatment of space ...

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 ...

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 ...

C hina has decided to take hypergravity to a whole new level – testing both materials and fundamental physics in a regime we ...

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 and the latter a point in space, but in both cases the normally ...

Because the moon has less gravity than Earth does, time passes slightly differently there. This effect was first predicted by ...
