How can physics on the smallest scales affect what the Universe does on its largest ones? Cosmic inflation holds the answer. On a macroscopic level, the Universe appears to be entirely […]

If this discovery came in a pre-LIGO era, maybe it would have been a surprise. But in 2019, there’s no mystery at all. Did you hear that astronomers had recently […]

Without this one ingredient, there wouldn’t be enough ‘glue’ to hold the Universe together. Of all the things in the Universe to be thankful for — the stars, planets, atoms, molecules, and […]

The shape of our Universe has long been recognized to be flat. But that isn’t the only possibility. The Universe is expanding, and goes on for farther than even our […]

If an AT-AT walker (or something even larger) wanted to walk across a frozen lake, how thick would the ice have to be? Each winter, one of the most spectacular phenomena […]

The Leonid meteor shower peaks today. Its parent comet taught us where meteor showers come from. Every year, as Earth regularly orbits the Sun, meteor showers repeatedly recur. While August’s Perseids […]

Even before MMA was a combat sport, it was a unique type of astronomy. Today, it’s opening up the Universe as never before. On February 24, 1987, a spectacular signal was […]

For decades, one of the Big Bang’s greatest predictions was shrouded in doubt. The answer was always there on Channel 3. When it comes to the question of how our Universe […]

A theoretical view of a distant world so far from our Sun that our Solar System appears barely brighter than the remaining stars in the sky. ( Caltech/R. Hurt (IPAC)) Pluto […]

Our Universe is 13.8 billion years old, and our Sun formed about 2/3rds of the way through. Here’s what came before it. When it comes to the great cosmic question of […]

The origin story for our Universe got a major revision nearly 40 years ago. Time to catch up. 13.8 billion years ago, all the matter and energy contained within our Universe […]

Simply getting into grad school isn’t enough. The answers to these three questions can make all the difference. It’s time. You’ve done all your research into schools, completed your undergraduate […]

In the mid-20th century, ‘physical cosmology’ was considered an oxymoronic joke. Today, it’s Nobel-winning science. Imagine you wanted to know everything you could about the Universe. You’d want to find […]

Many deserving potential awardees were snubbed by the Nobel committee. But this takes the cake. Every October, the Nobel foundation awards prizes celebrating the greatest advances in numerous scientific fields. Alfred […]

A recent headline claimed they could. But if gamma-rays are just a form of light, don’t they have to travel at light-speed? There’s an ultimate speed limit in the Universe: […]

A fully programmable quantum computer that can outperform any classical computer is right at the edge of today’s technology. Earlier this month, a new story leaked out: Google, one of […]

She’s not a scientist, an expert, or even an adult. But she’s got one good lesson to teach us all. Like most people on Earth, Greta Thunberg is not a climate […]

It would be the ultimate method for solving our pollution or hazardous/radioactive waste problems, but we’ll never do it. Here’s why. Imagine our planet as it was for the first 4.55 […]

In 1789, William Herschel discovered this unique moon around Saturn. 230 years later, its secrets are more promising than ever. Today marks the 230th anniversary of the discovery of Enceladus, one […]

Electron-positron or proton-proton colliders are all the rage. But the unstable muon might be the key to unlocking the next frontier. If you want to probe the frontiers of fundamental […]
