Is the Universe Made of Math? Part 2: The Minimalist Universe

Like, it shouldn’t be this easy. Yeah I know physics is kind of hard, and it has taken us centuries to reach our present level of knowledge, and we know we’re still a long way from complete knowledge of time and space.

A New Study Finds a Subtle Dance Between Dark Matter and Neutrinos

Scientists are a step closer to solving one of the universe's biggest mysteries as new research finds evidence that dark matter and neutrinos may be interacting, offering a rare window into the darkest recesses of the cosmos.

This System Reveals How Super-Earths Are Born

One of the best things about being able to see thousands of exoplanetary systems is that we’re able to track them in different stages of development. Scientists still have so many questions about how planets form, and comparing notes between systems of different ages is one way to answer them. A new paper recently published in Nature by John Livingston of the National Astronomical Observatory of Japan and his co-authors details one particularly interesting system, known as V1298, which is only around 30 million years old, and hosts an array of four “cotton candy” planets, which represent some of the earliest stages of planet formation yet seen.

Is the Universe Made of Math? Part 1: The Unreasonable Tool

Imagine you walk into a parking lot full of cars. You have in your pocket one single key. It’s the key to your car. The same key you’ve always used, the same key you’ve always trusted, the same key that you always manage to realize that you’ve lost right when you’re rushing out the door.

The Milky Way’s Black Hole Is Quiet Now, But Its Recent Past Was Far More Active

The supermassive black hole in the Milky Way's galactic center, Sagittarius A-star, is known for being quiet and dim. But that wasn't always the case. The powerful XRISM x-ray telescope shows that it flared brightly at least once in the very recent past.

Does Free Will Exist? Part 4: An Emergent Universe

But we’re not going for one thing or another, are we? We’re here to explore ideas – that’s most of the fun anyway. And there’s one more aspect of physics that takes part in the free will discussion, and that’s the concept of emergence.

To Keep Water Liquid, the Red Planet Needed to Freeze

Mars has a curious past. Rovers have shown unequivocal evidence that liquid water existed on its surface, for probably at least 100 years. But climate models haven’t come up with how exactly that happened with what we currently understand about what the Martian climate was like back then. A new paper, published in the journal AGU Advances by Eleanor Moreland, a graduate student at Rice University, and her co-authors, has a potential explanation for what might have happened - liquid lakes on the Red Planet would have hid under small, seasonal ice sheets similar to the way they do in Antarctica on Earth.
