June 12, 2026 What If the Largest Objects in the Universe Collided?
In this episode, we're going to smash big things into each other. Why stop at smashing two gargantuan black holes, when you can do the same with the most massive stars, the largest planets, and even two galaxies? It's going to get explosive.

June 11, 2026 What If Theia Never Crashed into Earth?
Roughly 4.5 billion years ago, a Mars-sized protoplanet called Theia slammed into early Earth, an event believed to have formed the Moon and shaped life as we know it. But what if that impact never occurred?

June 10, 2026 What If You Jumped Into Saturn?
Saturn is famous for its magnificent rings. But did you know other gas planets like Jupiter, Uranus, and Neptune also have rings? Saturn's are just the largest and most visible. Saturn radiates twice as much energy into space than it receives from the Sun. And that means it must have an internal heat source. Do we know what it is? Absolutely not. Well, today we're sending Chase to find out!

June 09, 2026 Mating with an Alien
It's a beautiful night. Just you, a bottle of wine, and your partner drifting through the cosmos in a UFO. As you caress their green skin, you know tonight's the night you're mating with an alien. But would your anatomy be compatible? How would conception take place? And what would your child look like?

June 04, 2026What If You Fell Into the Biggest Void in the Universe
It's a place where nothing exists. A place without stars, planets, or galaxies. A place where you wouldn't meet a soul for hundreds of millions of light-years. This place is called the Boötes Void, or as I like to call it, The Great Nothing.
Unless you find your way back to your ship, you'll be drifting through the perplexing dark of this mysterious nothing for billions of years. That is, your frozen, desiccated body would drift through this expanse for billions of years because there's nobody out here to retrieve you.

Timeline:

03:24 Leaving Earth and Interstellar Travel
04:26 Leaving the Milky Way Galaxy

06:57 Inside the Largest Void in Space
08:25 How Scientists Discovered the Boötes Void
09:54 Why Voids Exist in the Universe
11:36 How Empty Is Space Really?
13:42 Are There Galaxies in the Boötes Void?
14:30 What Happens If You’re Lost Forever

June 03, 2026 What If Quetzalcoatlus Were Still Alive?
A terrifying shadow ripples over the city as a gigantic prehistoric beast soars over the towers, moving faster than the cars on the freeway, hunting. And it's not alone; it hunts in a pack. This was... and IS Quetzalcoatlus. Because today, we're bringing this creature back from extinction. How exactly did Colombian drug lord Pablo Escobar get mixed up in all this? Hold on for that.

What exactly is Quetzalcoatlus? It resembles a dinosaur or a pterodactyl but is neither. This enormous flying creature is a pterosaur, which means it's a reptile. A big one.
