Black holes happen when you have a super huge, mega-giant amount of stuff --- crammed into a super-tiny, infinitely-small amount of space. AND THEY ARE SUPER COOL! In this episode, we learn all about what black holes are and how we found out they were real. We talk to a black hole hunter who has discovered supermassive black holes. And we find out what a wormhole is and why it might really, be really, really hard to ever find one -- or travel through it.

There’s a bunch of vitamins and minerals our bodies need to do their body thing. Our bodies don’t make them, so we get them through food – except for vitamin D! We can get vitamin D from the UV rays from the sun, but the UV rays from the sun can also do damage. Listen to this episode to find out why you have to wear sunscreen, how we’re able to get vitamin D, and how we discovered vitamins in the first place!

We are super-excited to let you know that our pals at Forever Ago just started a brand new season. Host of Forever Ago, Joy Dolo, will dive into all sorts of cool history including trick or treating, the Wizard of Oz and pizza, just to name a few. The season kicks off with an episode all about how Pokemon was invented. It’s so cool that we want to share it with you right now. And if your a Hoax head, the Hoax Hunters have a bonus Pokemon episode in our Smarty Pass feed. It’s almost too good to be true. But guess what: it is! Until then, enjoy the episode!

This is a sneak peek of a bonus episode available to Smarty Pass subscribers. It’s a follow up to the Forever Ago episode about the history of Pokemon. This time, Marc and Sanden are back as the Hoax Hunters to investigate a phenomenon known as the Pokemon Shock. It was an event where a TV show apparently made thousands of people feel sick.

Get ready for some smiles! We’re looking at the science of two things that bring us joy: tickles and cuteness.

We’ll explain why tickles make us giggle and why you can’t tickle yourself. Then we’ll talk about what makes cute things cute and why sometimes we want to eat or smoosh cute things.

Marc and Sanden are back as the Hoax Hunters! This time they look at the case of the Fresno Nightcrawler. In 2007 a man’s security camera recorded something strange outside his house. It looked like sweatpants out for a walk by themselves, with no humans around. Creepy? Kind of. Unexplained? Very. Join the Hoax bros as they explore this event and learn how it inspired artists, musicians, even the tourist board of Fresno, to embrace the weird stuff around us.

Our brains are amazing machines, but they are also very delicate. We have to wear helmets when we bike, skate, or do other activities where we might bang our skulls. Why is the brain so sensitive? Turns out, it’s a soft blob a lot like tofu, but that softness lets it do some pretty important things. Join Molly and co-host Penny as they learn about our wonderful, squishy brains. Plus, Dwayne the Brain joins us and we’ve got a brand new Mystery Sound.
