The geometry does the work — no fudged parameters required.

Art Bell welcomes physicist Janna Levin, professor of physics and astronomy at Barnard College of Columbia University, for a wide-ranging exploration of whether the universe is finite or infinite. The evening begins with open lines as callers weigh in on the Virginia Tech tragedy, top conspiracies, and whether alien civilizations would contact humanity given its violent tendencies. Art reads from reports about mass shootings becoming more common since the 1960s and a Swedish physicist… Full show notes & guests: https://artbellarchive.org/episode/april-21-2007-physics-and-cosmology-janna-levin
BLACK HOLES, THE BIG BANG & ALIEN LIFE: Astrophysicist Janna Levin Breaks Down the UniverseEver wondered what existed before the Big Bang? Or why all planets are different, and why Earth is so perfectly suited for life?In this mind-expanding episode of Mayim Bialik's Breakdown, renowned astrophysicist and author of Black Hole Survival Guide, Janna Levin (Professor of Physics and Astronomy at Barnard College of Columbia University), takes us on a cosmic journey through the deepest mysteries of the universe, and how they reflect back on what it means to be human.From the terrifying truth about black holes to the surprising science behind moons, planets, and even nuclear weapons, we're answering space questions you didn’t even know you had.Janna Levin breaks down:- Everything You’ve Ever Wondered About the Big Bang: What came before it, myths, how it created space and time- What is Time and how do black holes bend it?- Why planets are round- What moons really are (and the wild origin of our Moon)- How stars give birth to planets- What black holes are, what happens inside, and their role in the fundamentals of physics- Why some stars become black holes and others don’t- How Einstein and Oppenheimer cracked the code on black holes and how we observe them today- What would happen if our Sun became a black hole and could we actually fall into one?- Spooky effects of black holes on time & space (Could they teach us to age slower?)- Why there’s likely a black hole at the center of every galaxy- Why Janna Levin believes we’ll discover alien life within 50 years & what it could look like (it will likely be on moons, not planets!)- Will our tragic reliance on tech destroy us, or save us?- Can we make tech more compatible with nature?- Why advancing tech increases the generational gap- Why Janna doesn’t believe AI will ever become truly conscious- Why the universe is considered left-handed- What would happen if the Sun were knocked out of our system- Nuclear weapons & how they were invented through studying the Sun- Parallels between nature and cosmic phenomena across the universeThis episode of MBB is really all about the growing hunger in society to understand the cosmos, and therefore, ourselves. Don’t miss this mind-blowing journey into the heart of space, time, existence, and our place in it all!

Black holes get a bad rap. They’ve been cast as the monsters of the cosmos — gobbling up stars and stretching anything that gets too close into cosmic spaghetti. But Black Hole expert Janna Levin has spent her career decoding these mysterious objects, and she thinks they’re just misunderstood. In this episode, she dives into the strange physics of black holes: what they are, what they sound like, what happens if you fall into one, and how there’s a lighter side to every black hole. Janna shares why black holes might not be the end of everything — but the beginning of something even weirder.
