Building 29

All things in the cosmos have a lifespan, from the smallest particles to the most ancient suns. Everything has its season. Every season must come to an end. And this episode marks the end of Orbital Path. So, for the last transit of our podcast, Dr. Mi...

Hello, Asteroid!

Asteroids, as the dinosaurs found out, can have big effects on life on Earth.  Sixty-five million years ago, an asteroid crashed into the Yucatán. The impact caused apocalyptic tsunamis and volcanic eruptions. Grit and ash blotted out the sun. It wiped...

Black Holes from the Dawn of Light

To make a black hole, you need to think big. Really big. Start with a star much bigger than the sun — the bigger the better. Then settle in, and wait millions and millions and millions of years for your star to die. That should do the trick, if you wan...

Space Lasers for the Home Planet

On September 15, 2018, the last Delta II rocket lifted off from Vandenberg Air Force base, in California. It carried into orbit IceSat-2 — a satellite equipped with perhaps the most sophisticated space laser ever built.   NASA didn’t put it up there to...

Brian Greene goes to 11 — again

We live our lives in three dimensions. But we also walk those three dimensions along a fourth dimension: time. 

Our world makes sense thanks to mathematics. Math lets us count our livestock, it lets us navigate our journeys. Mathematics has also prove...

The Universe of Leonard Susskind

To hear Leonard Susskind tell it, we are living in a golden age of quantum physics. And he should know. Susskind is a grandee of theoretical physics. In the 1960s, he was one of the discoverers of String Theory. His friends and collaborators over the y...

Mars Goes Organic

For a long time, probably as long as we have been gazing up at the night sky, people have been asking ourselves: Are we alone? Is there life out there, anywhere else in the universe? For modern Earthlings, our fascination with extraterrestrial life has...
