Summary

Leonard Susskind joins us to discuss why the crisis in string theory is deeper than most realize, examining its conceptual limits and the search for a more complete quantum gravity framework. We explore the history of the theory, recent critiques, and possible paths forward.- 00:00 - IntroSPONSORS:- I personally subscribe to The Economist.

0:00.0

We live in the wrong kind of world to be described by string theory.

0:06.0

No physicist has ever won a big prize for string theory.

0:09.3

I can tell you with absolute certainty that it is not the real world that we live in.

0:14.1

So we need to start over.

0:18.1

In a groundbreaking revelation, Leonard Suskind, one of the founding fathers of string theory

0:24.2

and professor of theoretical physics at Stanford University makes a stunning admission.

0:29.8

String theory has failed, and many physicists don't know what to do.

0:35.5

They're scared. They might get a job.

0:38.0

The theory that once promised to unify physics

0:40.6

has instead generated 10 to the 500 different possible solutions, or vacuum states.

0:47.2

Some theorists maintain that each mathematical solution corresponds to a physical reality,

0:52.5

a legion of multiverses.

0:54.0

However, the extensive efforts to tame this so-called landscape, corresponds to a physical reality, a legion of multiverses.

0:59.3

However, the extensive efforts to tame this so-called landscape through, for instance,

1:06.2

KKLT vacuist stabilization mechanisms, suggests an implicit acknowledgement that the multitude of universes is senseless.

1:07.6

I'm Kurt Jymungle, and on this channel, I explore unification and physics and

1:12.2

philosophy using my background in mathematical physics from the University of Toronto. Today,

1:17.2

it's a special treat since we have the legendary Leonard Suskind in rare, candid form, revealing

1:22.8

his unconfined thoughts for the first time. We should certainly be on the lookout for ideas which are not the consensus.

1:35.2

We should be watching for them and not immediately dismiss them.

1:40.2

We also talk about what it means that the universe is a hologram, why quantum entanglement is equivalent to wormholes,

1:46.9

why super symmetry is absent in our universe, why we lack a quantum description of decider space,
