What's Out There?: From Black Holes to Mars Missions
Right now, the Milky Way is swallowing a smaller galaxy. A neutron star somewhere is spinning 716 times per second. Light from a star that died before Earth existed is just reaching us tonight. The universe is doing a thousand impossible things — and most people have no idea. You don't need to know any physics or memorize any formulas — just bring your curiosity. Every lesson starts with a question you've probably already wondered about, like "What happens inside a black hole?" or "Why hasn't anyone answered our signals?" — and answers it with real science, wild metaphors, and zero textbook energy. By the end, you'll be the person who actually understands why stars explode, what dark matter is (and isn't), why the universe is expanding faster than it should, and how every atom in your body was forged inside a dying star. That's not trivia — that's understanding where you come from.
Universe
What you’ll learn
Your cosmic neighborhood
Discover why Pluto got "fired," what the Goldilocks zone actually means, and why the distances between stars will genuinely break your brain. You'll know your full cosmic address — six lines long — and understand why we might not be alone. You'll explain it to anyone.
Stars are born, live, and explode — and that made you
Learn how a boring gas cloud ignites into a star, why color reveals a star's entire destiny, and the truth that changes how you see yourself: the calcium in your bones and iron in your blood were forged inside stars that died billions of years ago. You'll never look at the night sky the same way.
The universe is wilder than you think
Galaxies collide (beautifully, not catastrophically). 95% of the universe is a total mystery — dark matter, dark energy, things we can't see or touch. Black holes break every rule. And the Big Bang wasn't an explosion IN space — it was an explosion OF space. You'll finally get why scientists say "we
The biggest questions — including the one about you
Why is no one answering our signals? How do telescopes see the past? What happens when even black holes evaporate? And the final realization that ties everything together: you are 13.8 billion years of cosmic history, stardust that learned to ask questions about stars. This is where it all clicks.
