Walkabout the Galaxy
Moon; time; Milky Way
Astrophysics and Astronomy | Physics
What time is it on the Moon? It turns out the answer to that is not as easy as just lining it up with a time on the Earth. Worse, it's not even that obvious what time it is on the Earth. That's just one of many topics we explore in this episode, including a discovery that the Milky Way is much larger than previously thought, and tracing water molecules from the interstellar medium step by step into that cool glass you have with dinner. Join us for all that, time trivia, and more.
Feel the warmth of the sun on your skin thanks to nuclear fusion. Bringing energy to the Earth for over 4.5 billion years, and light in the universe for over 13 billion, the driving force for life on Earth, nuclear fusion is responsible for all the non-hydrogen atoms in you and all your friends and family. With the ability to convert mass into energy, and one element into another, nuclear fusion is your one-stop shop for just about every problem you may encounter. So the next time you find yourself in a difficult situation, try nuclear fusion. Available in every star, and coming soon to laser facilities and tokamaks near you. Nuclear fusion, let's bond (Elmer's Glue).
