The combination of charge conjugation, parity, and time-reversal symmetry is known as CPT. And it must never be broken. Ever. The ultimate goal of physics is to accurately describe, as precisely […]

Despite its prominence in our collective imagination, variations in metabolism play a minor role in obesity.

A new survey indicates that large financial institutions are relaxing restrictions around mobile trading, increasing the volume of deals done via mobile apps 31% in 2017 from the year before.

LIGO just announced the second neutron star-neutron star merger ever seen in gravitational waves. It doesn’t match the first. On August 17, 2017, an event occurred that forever changed how we […]

There is a fundamental difference between matter and antimatter. But not enough of one to explain our Universe. Our Universe is a vast and enormous place, and if there’s one […]

There is a reason why anti-vaxx attitudes are hard to shake, explains a new study.

The dream of multi-messenger astronomy is to seen an event with gravitational waves, neutrinos, and light all together. The newest candidate just might get us there. When it comes to cataclysmic […]

Before the Big Bang… after the Big Freeze… will everything look the same? “What is wild cannot be bought or sold, borrowed or copied. It is. Unmistakeable, unforgettable, unshamable, elemental as […]

Like sneaking veggies into dessert, these board games teach STEM, strategy, and executive functions through the joys of play.

If they saw us as we were before the recent industrial revolution, would there be any reason to particularly care about us? All across the Universe, trillions of galaxies can be […]

Before there were humans, planets, or even stars and galaxies, we had to make the first elements. Here’s how they happened. From the first moments of Big Bang to the […]

In 2017, we saw gravitational waves a neutron star merger for the first and only time. And it keeps getting more interesting. On August 17, 2017, a cosmic signal arrived […]

The first planets were only gas. The second included rocky ones, but life wasn’t possible. Here’s how we finally got there. Here in the Universe today, potentially habitable planets are practically […]

With hundreds of billions of stars burning bright, ‘dead’ seems like a bit of an exaggeration. But every galaxy is headed for this fate, including ours. As long as a […]

In all the Universe, there’s only one Earth. But can we find the other worlds that are like ours? Even though the ingredients for life have been confirmed to be practically […]

It’s so much more than mass-energy equivalence; it’s the key to unlocking the quantum Universe. For hundreds of years, there was an immutable law of physics that was never challenged: […]

For the first time, we’ve seen neutron stars merge. At last, the gravitational and electromagnetic sky are one. “It’s becoming clear that in a sense the cosmos provides the only laboratory […]

Finding a warm-hot intergalactic plasma is amazing! But we still need dark matter just as much as ever. “There are stars leaving the Milky Way, and immense gas clouds falling […]

Now that it’s seen gravitational waves, could physics beyond Einstein be its next target? This post is written by Sabine Hossenfelder, a theoretical physicist specialized in quantum gravity & high energy […]

Researchers may have discovered the oldest homo sapiens yet, in Morocco.

The first detections were incredible. But now the real fun — and the real science — truly begins. On August 17, the signals from two merging neutron stars reached Earth after a journey of 130 […]

Comparing NYC to Luxembourg, by way of iceberg A-68

The neutron star-neutron star merger was initially only seen in 1 detector out of 3. Here’s how scientists didn’t let it slip away. On August 17th, 2017, a gravitational wave event […]

We compiled a list of seven of the greatest public speakers of all time, people who forever changed the course of history with their words.

‘Luck’ is the wrong word. The Universe cooperated, but we gave ourselves the opportunity by being prepared. It was already 28 years ago that the Hubble Space Telescope was launched […]

There were two periods of exponential expansion in the Universe: one today and one long ago. Are they related? “What is wild cannot be bought or sold, borrowed or copied. […]

Science's signature moves share something with good poetry. Good metaphor-making can make geniuses of both kinds. But bad metaphors can mislead whole fields.  

The “Philosopher-King” of comedy is Louis C.K. You may know his work, but you might not realize there is some serious philosophy behind some of the best jokes.

Each discovery we make seems to raise even more questions. It’s a wonderful example of how science never ends. On August 17th, both the light and the gravitational wave signals from […]

Most stars obey very similar rules, making them almost entirely predictable. But then, there are the weirdos. Catch this live-blog event to learn more. When we look out at the Universe […]
