Einstein's equations and the enigma of wormholes | Janna Levin

Quantum wormholes are mathematically possible — but might also be physically impossible. Physicist Janna Levin explains the wormhole paradox.

Theoretical cosmologist Janna Levin challenges long-held assumptions about the behavior of black holes, information conservation, and the fundamental nature of space, time, and gravity. She uses black holes to explore the physical feasibility of wormholes: theoretical passages or tunnel-like structures that connect separate points in spacetime.

Stephen Hawking proposed that black holes emit energy via quantum particles, causing them to eventually evaporate and challenge the conservation of information. The holographic principle suggests that information is encoded on a black hole's surface, addressing the information paradox.

Levin metaphorically likens black holes to embroidery, woven from quantum threads. Her quantum perspective has profound implications, potentially altering our understanding of gravity and spacetime's fundamental nature — even questioning our pursuit of a theory of everything.

About Janna Levin:
Janna Levin is a professor of physics and astronomy at Barnard College of Columbia University. She is also director of sciences at Pioneer Works, a center for arts and sciences in Brooklyn, and has contributed to an understanding of black holes, the cosmology of extra dimensions, and gravitational waves in the shape of spacetime. Her previous books include How the Universe Got Its Spots and a novel, A Madman Dreams of Turing Machines, which won the PEN/Bingham Prize. She was recently named a Guggenheim fellow.
