What If Quetzalcoatlus Never Went Extinct?

Dying in the Most Terrifying Places in the Universe

Last year, you loved watching me push the limits of science in the most extreme environments imaginable. In the name of discovery and exploration across every planet in our Solar System, the WHAT IF team is back—and this time, we’re raising the stakes even higher. Get ready for bigger questions, crazier scenarios, and some of the most hostile places in the Universe. We’re talking supernovas, black holes, and entire galactic clusters reaching temperatures of over 160 million Kevins (that’s a LOT of Kevins). How extreme can things really get? And what would happen if we went there? Let’s find out. 🚀 Support us on Patreon: patreon.com/whatifshow/membership [https://www.patreon.com/whatifshow/membership] Get the What If book: bit.ly/ytc-the-what-if-100-book [http://bit.ly/ytc-the-what-if-100-book] Join this channel to get access to perks: youtube.com/channel/UCphTF9wHwhCt-BzIq-s4V-g/join [https://www.youtube.com/channel/UCphTF9wHwhCt-BzIq-s4V-g/join] Interested in sponsoring our episodes or collaborating?

What If You Dug a Hole Through Mars?

What if you started digging and never stopped, until you broke through the other side of Mars? Would you fall forever? Would Mars’ gravity crush you?

What If Humanity Became a Type 7 Civilization?

Imagine a world where you're not even human. You can create universes with ease and control time. This could be a reality in an incredibly advanced civilization. Is a type 7 civilization even possible? What would humans look like? And why might something like this be a terribly bad idea?
