Questions Show: Galileoscope, Black Hole Time, and What Exactly is Energy?
How can you get a Galileoscope of your very own? What happens to time inside a black hole? And what exactly is energy anyway? If you’ve got a question for the Astronomy Cast team, please email it in to info@astronomycast.com and we’ll try to tackle it for a future show.

Ep. 140: Entanglement
One of the most amazing aspects of quantum mechanics is quantum entanglement. This is the strange behavior where particles can become entangled, so they’re somehow connected to one another – no matter the distance between them. Interact with one particle and the other reacts instantly; if if they’re separated by billions of light-years.
Questions Show: Telescope Suggestions, Black Hole Energy, and Universal Time
What starting telescope equipment does the Astronomy Cast team suggest? How much energy does a black hole generate? And how do we measure time outside the Earth?

Ep. 139: Energy Levels and Spectra
Last week we took a peek into the tiny world of quantum mechanics, and its unintuitive, but very accurate mathematical predictions. And although we all appreciate the physics lesson, you’re probably wondering what this all has to do with astronomy. Well, today we bring it all home and explain how quantum mechanics has given astronomers one of the most powerful tools they have to study the nature of the cosmos.
Questions Show: An Unlocked Moon, Energy Into Black Holes, and the Space Station’s Orbit
What would happen if the Moon wasn’t tidally locked to the Earth? What happens to all that mass and energy disappearing into a black hole? And how can we explain the space station’s crazy orbit? If you’ve got a question for the Astronomy Cast team, please email it in to info@astronomycast.com and we’ll try to tackle it for a future show.

Ep. 138: Quantum Mechanics
Quantum mechanics is the study of the very tiny; the nature of reality at the smallest scale. It’s a science that defies common sense, and delivers no helpful analogies. And yet it delivers the goods, making scientific predictions with incredible accuracy. Let’s look into the history of quantum theory, and then struggle to comprehend its connection to the Universe.
