CERN’s Large Hadron Collider is the most powerful particle accelerator ever. To go even further, we’ll have to overcome something big.

The mutual distance between well-separated galaxies increases with time as the Universe expands. What else expands, and what doesn’t?

With new W-boson, top quark, and Higgs boson measurements, the LHC contradicts earlier Fermilab results. The Standard Model still holds.

Figuring out the answer involved a prism, a pail of water, and a 50 year effort by the most famous father-son astronomer duo ever.

Dark energy is one of the biggest mysteries in all the Universe. Is there any way to avoid “having to live with it?”

The first stars in the Universe were made of pristine material: hydrogen and helium alone. Once they die, nothing escapes their pollution.

A next-generation LHC++ could cost $100 billion. Here’s why such a machine could end up being a massive waste of money.

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

When people pick the greatest scientist of all-time, Newton and Einstein always come up. Perhaps they should name Johannes Kepler, instead.

The majority of the matter in our Universe isn’t made of any of the particles in the Standard Model. Could the axion save the day?

Everything else in the universe is either a particle or field. Dark energy behaves as neither, and it may be a property inherent to space itself.

Beyond stars, galaxies, and gravity, studying the fundamental workings of nature reveals widely applicable lessons for learners everywhere.

The whole isn’t greater than the sum of its parts; that’s a flaw in our thinking. Non-reductionism requires magic, not merely science.

Artificial intelligence is much more than image generation and smart-sounding chatbots; it’s also a Nobel-worthy endeavor rooted in physics!

Despite many ultra-distant galaxy candidates found with JWST, we still haven’t seen anything from the Universe’s first 250 million years.

In the early stages of the hot Big Bang, there were only free protons and neutrons: no atomic nuclei. How did the first elements form from them?

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

Science cannot help us understand or describe first-person experience. Zen koans are a powerful form for helping us reach that description.

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

So far, gravitational waves have revealed stellar mass black holes and neutron stars, plus a cosmic background. So much more is coming.

We can describe what we see happening, but we don’t understand why. Despite our vast cosmic knowledge, enormous unknowns remain. The quantum fluctuations inherent to space, stretched across the Universe […]

In 2017, a kilonova sent light and gravitational waves across the Universe. Here on Earth, there was a 1.7 second signal arrival delay. Why?

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.

Though ultimately incorrect, the ancient Greek philosophers blazed a conceptual trail for humankind to understand the nature of reality.

Hermann Minkowski called Einstein a “lazybones” with a “not very solid” education. Less than 10 years later, he would eat his words.

For nearly 25 years, we thought we knew how the Universe would end. Now, new measurements point to a profoundly different conclusion.

If it weren’t for a subatomic quantum rule, our Universe would be vastly different. In many ways, our views of the distant Universe are the closest things we’ll ever get […]

Mathematically, it is a monster, but we can understand it in plain English.

As early as we’ve been able to identify them, the youngest galaxies seem to have large supermassive black holes. Here’s how they were made.

Many mavericks look to Einstein as a unique figure, whose lone genius revolutionized the Universe. The big problem? It isn’t true.
