Janna Levin: Black Holes, Wormholes, Aliens, Paradoxes & Extra Dimensions | Lex Fridman Podcast #468

FINALLY some Alien and Space Talk again. Those are by far my favourites! :)

Feels like I haven't listened to this version of lex in ages. Love Janna

I love that there are starting to be more scientific discussions again. All the political interviews may have been mildly interesting, but the scientific stuff is definitely the meat of this podcast.

More of these kinds of guests please!

Found Janna on the Startalk show and have been obsessed with her ever since. One of the most intelligent human beings on this planet. Her way of explaining things that are almost impossible for the average person to understand is an underrated skill. I actually come away from listening to her like, ok I almost can get my head around that and I was at best a B+ student for my whole life. I could listen to her talk for hours she is a true living legend of modern day physicists
