[00:00:00]There are over 2 trillion galaxies in the universe. [music] So, why have we heard absolutely nothing?

[00:00:07]In 1950, physicist Enrico Fermi [music] asked a simple question.

[00:00:12]Where is everybody?

[00:00:14]It became one of the >> [music] >> biggest mysteries in [music] science.

[00:00:24]The universe is unimaginably large.

[00:00:27]There are likely billions [music] of Earth-like planets.

[00:00:30]And statistically, intelligent life should be [music] everywhere.

[00:00:34]So, why haven't we found any evidence?

[00:00:37]No signals, no ships, no visitors, just silence.

[00:00:42]Our galaxy alone contains around [music] 100 billion stars.

[00:00:46]And many of those stars have planets.

[00:00:49]Even if a tiny [music] fraction developed life, there should still be millions of civilizations.

[00:00:55]>> [music] >> Some could be millions of years older than us.

[00:00:59]With enough time, a civilization could colonize the galaxy. In theory, the Milky Way could [music] be explored in a few million years.

[00:01:08]That sounds long, but on cosmic [music] time scales, it's nothing. Maybe intelligent life is extremely rare. Maybe civilizations always destroy [music] themselves before becoming advanced. Nuclear war, AI, climate collapse. This idea is [music] called the Great Filter. A hidden barrier that most civilizations never survive. Or maybe they're already here, but avoiding us, like humans observing animals in a zoo.

[00:01:40]>> [music] >> One of the most disturbing theories is called Dark Forest Theory.

[00:01:46]The universe may be silent [music] on purpose.

[00:01:49]Every civilization stays hidden because revealing [music] your location could mean extinction.

[00:01:56]In a dark
