Buckle up, folks! The latest episode of "What The IF?" is an absolute cosmic ride. In this mind-bending episode we answer long time listener and Super IFFer Bill’s serious questions about cosmic strings. What the heck are those, you might ask? Well, they're not some kind of cool string instrument, but rather cosmological-scale things that could slice matter and cut out a thin slice of space. Yeah, we're not kidding - this stuff is straight out of a sci-fi movie!

But fear not, young padawans and super-ifs-in-training! Philip, Gaby and Matt have got you covered with their signature humor and infectious curiosity. Each week on "What The IF?" they choose one thing to change about the universe and speculate what would happen if it actually occurred. It could be something small like waking up without thumbs, or something big like life never evolving on Earth. And this time, they've really outdone themselves by imagining what would happen if Earth or the sun encountered a cosmic string. Spoiler alert: things get weird.

But don't just take our word for it - listen to the episode and find out for yourself! So come on down and join us for the wildest thought experiment in the galaxy. Trust us, you won't regret it!
