We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole ...

Quantum mechanics has always carried a quiet tension. At its core, the theory allows particles to exist in many states at ...

Quantum theory has long treated time as a silent backdrop, a parameter that never jitters even as particles flicker in and ...

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

A viral conspiracy theory suggesting that the Earth will lose gravity for seven seconds in August this year has left people ...

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.

For the second time in as many months, images gathered by the Hubble Space Telescope (HST) are raising questions about the structures of time and gravity, and the fabric of space. Using two HST images ...

Lots of people, including Einstein (see above), talk about gravity, the restraining force which makes people walk on floors instead of floating in midair. What worries Roger Babson, 74, economic ...

What if gravity isn’t weirdly quantum at all, but rather … just a bit messy? The holy grail of theoretical physics is to find the long-sought theory of quantum gravity. But what if this theory is as ...

The original version of this story appeared in Quanta Magazine. At the beginning of time and the center of every black hole lies a point of infinite density called a singularity. To explore these ...
