00:00Does consciousness live on after death?

00:03Quantum hypothesis points to multiverse after death.

00:07Death is certain, but what follows sparks debate.

00:10Quantum immortality suggests that in parallel realities,

00:14one version of you always survives.

00:17And that's where your consciousness continues,

00:19an intriguing yet hypothetical and controversial theory.

00:25Quantum immortality comes from the many worlds interpretation,

00:29where reality splits into branches for every outcome.

00:33In this view, your consciousness always continues in the branch where you survive,

00:37making your experience appear endless, essentially immortal.

00:41The idea traces back to Hugh Everett III,

00:44who proposed the many worlds interpretation in 1957,

00:48later popularized by physicist Bryce DeWitt.

00:51Quantum immortality, however, only emerged in the 1980s

00:55through thinkers like Ewan Squires, Hans Moravec, and Bruno Marschall,

01:00and remains a fringe theory.

01:04Critics argue quantum immortality is flawed.

01:08Though survival branches may exist,

01:10physics assigns probabilities,

01:12and those where you constantly survive carry tiny weight.

01:15So, the odds of living forever are extremely small,

01:19making the theory highly unlikely.

01:21Even in many worlds,

01:22scientists say typical observers wouldn't survive forever,

01:25since most outcomes still end in death.

01:28Quantum immortality assumes consciousness can jump branches,

01:32but MWI lacks this mechanism.

01:35This challenges quantum immortality.

01:37Quantum immortality is enticing,

01:42but nearly impossible to prove.

01:44Without a way to hop between branches and bring back evidence,

01:47it stays more fiction than fact.

01:50Even in many worlds,

01:51survival odds are tiny,

01:53though daily choices like diet,

01:54exercise, and sleep still shape outcomes.

01:56So, let's take a look at it.
