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.
