What If: Science, Theory, and Possibilities

Dying in the Most Terrifying Places in the Universe 02.06.2026 23mnt

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 Get the What If book: bit.ly/ytc-the-what-if-100-book Join this channel to get access to perks: youtube.com/channel/UCphTF9wHwhCt-BzIq-s4V-g/join Interested in sponsoring our episodes or collaborating?
