Searching for dark matter, the XENON collaboration found absolutely nothing out of the ordinary. Here’s why that’s an extraordinary feat.

As particles travel through the Universe, there’s a speed limit to how fast they’re allowed to go. No, not the speed of light: below it.

What do ghosts and anomalous galaxy rotation rates have in common? Some sci-fi enthusiasts believe the answer involves “parallel universes.”

All matter particles can act as waves, and massless light waves show particle-like behavior. Can gravitational waves also be particle-like?

It’s an agricultural moonshot: Scientists hope to increase plant yields by hacking photosynthesis, the process that powers life on Earth.

It’s a wild idea, but there’s a way to test it. No matter how far we look out in the Universe, there’s always more “Universe” to see. Even at the extreme […]

A new survey, the DESI Legacy Imaging Survey, has found more lenses than all others put together. One of Einstein’s most revolutionary predictions is that mass bends light. During a […]

Our Universe requires dark matter in order to make sense of things, astrophysically. Could massive photons do the trick?

The controversy over the universe’s expansion rate continues with a new, faster estimate.

Yes, the Universe is expanding, but you might wonder, “How fast is it expanding?”

Two new studies examine ways we could engineer human wormhole travel.

Slimy biofilms made up of bacterial and eukaryotic life forms have taken over an abandoned, flooded uranium mine in Germany.

For 550 million years, neutral atoms blocked the light made in stars from traveling freely through the Universe. Here’s how it then changed.

Everything acts like a wave while it propagates, but behaves like a particle whenever it interacts. The origins of this duality go way back.

Cyberattacks are growing in number and sophistication.

Even with the quantum rules governing the Universe, there are limits to what matter can withstand. Beyond that, black holes are unavoidable.

Whole Foods Market founding CEO John Mackey synthesized the counterculture with capitalism and drove a food revolution.

Before there were planets, stars, and galaxies, before even neutral atoms or stable protons, there was the Big Bang. How did we prove it?

If you’re a massless particle, you must always move at light speed. If you have mass, you must go slower. So why aren’t any neutrinos slow?

Newton thought that gravitation would happen instantly, propagating at infinite speeds. Einstein showed otherwise; gravity isn’t instant.

Dark matter has never been directly detected, but the astronomical evidence for its existence is overwhelming. Here’s what to know.

Quantum superposition challenges our notions of what is real.

You might think it’s impossible to run out of wind, but Europe’s “wind drought” proves otherwise. And it’s only going to get worse.

Without these two elements, we’re doomed to fail. In this day and age, it’s virtually impossible to have sufficient expertise to figure out what the complete, comprehensive, scientifically validated truth surrounding […]

Although many of Einstein’s papers revolutionized physics, there’s one Einsteinian advance, generally, that towers over all the rest.

Photons come in every wavelength you can imagine. But one particular quantum transition makes light at precisely 21 cm, and it’s magical.

Human thinking is antiquated.

The same (former) NASA engineer who previously claimed to violate Newton’s laws is now claiming to have made a warp bubble. He didn’t.

Whenever someone waxes poetic about terraforming alien worlds, it’s worth taking a moment to consider the ethical implications of the proposal.

Invisible cloaks. Ghost imaging. Scientists are manipulating light in ways that were once only science fiction.
