The robot can drive heavy steal beams into the ground at a rate of 1 per 73 seconds, which will help expedite solar farm construction.

The highest-energy particles could be a sign of new, unexpected physics. But the simplest, most mundane explanation is particularly iron-ic.

Almost 100 years ago, an asymmetric pathology led Dirac to postulate the positron. A similar pathology could lead us to supersymmetry.

For every proton, there were over a billion others that annihilated away with an antimatter counterpart. So where did all that energy go?

Gravitational waves carry enormous amounts of energy, but spread out quickly once they leave the source. Could they ever create black holes?

From forming bound states to normal scattering, many possibilities abound for matter-antimatter interactions. So why do they annihilate?

As the Sun ages, it loses mass, causing Earth to spiral outward in its orbit. Will that cool the Earth down, or will other effects win out?

CERN’s NA64 experiment used a high-energy muon beam technique to advance the elusive search for dark matter, offering new hope for solving one of astronomy’s greatest mysteries.

If you bring too much mass or energy together in one location, you’ll inevitably create a black hole. So why didn’t the Big Bang become one?

A $30,000 electric vehicle with 400 miles of range that charges in under 10 minutes remains a pipe dream over the near future.

One of the fundamental constants of nature, the fine-structure constant, determines so much about our Universe. Here’s why it matters.

Today, the deepest depths of intergalactic space aren’t at absolute zero, but at a chill 2.73 K. How does that temperature change over time?

Capacitors, acid batteries, and other methods of storing electric charges all lose energy over time. These gravity-fed batteries won’t.

Energy balance is the greatest arbiter of weight gain. Embrace the “oinker diet.”

We need more data centers for AI. Developers are getting creative about where to build them.

A look back at the rise of solar power in the US and what’s next.

From the earliest stages of the hot Big Bang (and even before) to our dark energy-dominated present, how and when did the Universe grow up?

And can we run the grid of the future without AI?

As wind power grows around the world, so does the threat the turbines pose to wildlife. From simple fixes to high-tech solutions, new approaches can help.

The Universe is expanding, and the Hubble constant tells us how fast. But how can it be a constant if the expansion is accelerating?

McDermitt Caldera, the site of an ancient volcanic eruption, straddles the border of Oregon and Nevada.

First derived by Emmy Noether, for every symmetry a theory possesses, there’s an associated conserved quantity. Here’s the profound link.

The Universe isn’t just expansion, but the expansion itself is accelerating. So why can’t we feel it in any measurable way?

In general relativity, matter and energy curve spacetime, which we experience as gravity. Why can’t there be an “antigravity” force?

Black holes are the most massive individual objects, spanning up to a light-day across. So how do they make jets that affect the cosmic web?

Electromagnetism, both nuclear forces, and even the Higgs force are mediated by known bosons. What about gravity? Does it require gravitons?

Inflation, dark matter, and string theory are all proposed extensions to the prior consensus picture. But what does the evidence say?

In the year 2000, physicists created a list of the ten most important unsolved problems in their field. 25 years later, here’s where we are.

It’s not about particle-antiparticle pairs falling into or escaping from a black hole. A deeper explanation alters our view of reality.

The Universe has been creating stars for nearly all 13.8 billion years of its history. But those photons can’t match the Big Bang’s light.
