Time gets a little strange as you approach the speed of light.

Life may have arisen far earlier — and more rapidly — than previously thought.

From the Big Bang to black holes, singularities are hard to avoid. The math definitely predicts them, but are they truly, physically real?

No matter how good our measurement devices get, certain quantum properties always possess an inherent uncertainty. Can we figure out why?

Featuring SpaceX’s “Mechazilla,” a first-of-its-kind spacewalk, and more.

By probing the Universe on atomic scales and smaller, we can reveal the entirety of the Standard Model, and with it, the quantum Universe.

The first observational evidence showing the Universe is expanding is 100 years old now: in 2023. Here’s the story of its 100th anniversary.

Contrary to conventional wisdom, matter can escape the center of the Earth.

In logic, ‘reductio ad absurdum’ shows how flawed arguments fall apart. Our absurd Universe, however, often defies our intuitive reasoning.

A new measurement offers insights on the density of the mysterious force driving the Universe’s expansion.

Neutrons can be stable when bound into an atomic nucleus, but free neutrons decay away in mere minutes. So how are neutron stars stable?

The big-picture physics is simple – let gravity do its job.

There are some 26 fundamental constants in nature, and their values enable our Universe to exist as it does. But where do they come from?

Seeking life beyond the Solar System, we first look to the closest star systems with Earth-like planets. Here’s why that’s not good enough.

The science fiction dream of a traversable wormhole is no closer to reality, despite a quantum computer’s suggestive simulation.

Light can be turned into heat, which can then be turned into motion, and the effect of that motion can be turned into a big squeeze.

Dark matter’s hallmark is that it gravitates, but shows no sign of interacting under any other force. Does that mean we’ll never detect it?

How choosing Stoic acceptance — not dour resignation — galvanized great leaders from Thomas Edison to Phil Jackson and Tony Hawk.

NASA’s minivan-sized drone is scheduled to search for signs of life on Titan in 2034.

Two very different ideas, wormholes and quantum entanglement, might be fundamentally related. What would “ER = EPR” mean for our Universe?

For nearly 60 years, the hot Big Bang has been accepted as the best story of our cosmic origin. Could the Steady-State theory be possible?

One of the 20th century’s most famous, influential, and successful physicists is lauded the world over. But Feynman is no hero to me.

Chemists could replace bubbling flasks with tumbling ball mills.

Architecture in the age of AI — argues professor Nayef Al-Rodhan — should embed philosophical inquiry in its transdisciplinary toolkit.

The idea of “absolute time” was our default for millennia. But time is relative, as gravity and motion both cause time to dilate.

The fact that our Universe’s expansion is accelerating implies that dark energy exists. But could it be even weirder than we’ve imagined?

Within our observable Universe, there’s only one Earth and one “you.” But in a vast multiverse, so much more becomes possible.

No matter how beautiful, elegant, or compelling your idea is, if it disagrees with observation and experiment, it’s wrong.

Most fundamental constants could be a little larger or smaller, and our Universe would still be similar. But not the mass of the electron.

Or are cults the religions we find distasteful?
