Juan Maldacena says gravity isn't a fundamental force — it emerges from quantum entanglement. If he's right, spacetime itself is built out of quantum information, and Einstein missed it in 1935.
He's the most-cited theoretical physicist alive. We cover:
— why wormholes and quantum entanglement may be literally the same phenomenon
— what actually happens to information when you throw a laptop into a black hole
— how Hawking radiation accidentally gave cosmologists the equation behind
the structure of the universe
— whether sci-fi wormholes are ruled out by quantum mechanics itself
— the one unsolved problem Juan says matters more than black holes
(and it's not what you'd guess)
TIMESTAMPS
00:00 The claim Einstein wrote in 1935 and missed
01:15 The most-cited physicist alive walks into UC San Diego
03:25 What would shock Einstein most about modern physics
07:45 The holographic principle — what it actually means
09:20 Throw a laptop into a black hole. Now what?
11:00 General relativity says lost. Quantum mechanics says preserved.
12:25 The problem Juan wants to solve before he dies
13:50 Why real black holes don't emit measurable Hawking radiation
15:25 How black hole math accidentally explained why the universe has structure
17:00 Could primordial black holes be dark matter? Juan is skeptical.
18:30 Why a partition function went imaginary — and what it cost to fix
21:15 Why imaginary numbers keep being right about reality
25:00 How AdS/CFT got its name — and why physicists did the Macarena
27:05 We don't live in AdS space. Why does it matter?
29:00 Earth-sized wormholes are allowed. Faster-than-light ones aren't.
32:10 Could AI have helped Einstein in 1913?
33:00 Can a working physicist also believe in God? Juan answers.
