This extended cut is a deep dive into cutting edge research about black holes. It’s an interview with famous physicist Dr. Brian Cox. We start with “what if you fell into a black hole?” and end on the cutting edge research that had me questioning my whole reality.

I interviewed Dr. Cox originally for a shorter Huge If True episode all about what would happen if you fell into a black hole.

Watch our Huge If True episode about “What If You Fell Into A Black Hole?” here:    • Getting Sucked Into A Black Hole To Explai...  

But there was SO much weird and mind bending stuff about the cutting edge of black holes that didn't fit into that shorter episode, and we knew you'd want to hear it. So we decided we had to release the full conversation. It's just too cool and I think you'll love it.

Now, strap in, because the cutting edge of black holes is absolutely WILD.

Welcome to the joke down low:

Why should you never trust an atom?
Because they make everything up!

Find a way to use “atom” in a comment to let me know you’re a real one who made it to the end of the description :)
