00:00Ever wondered if you have another version of yourself in a parallel universe?

00:08Why in a galaxy full of planets haven't we found aliens?

00:14Encourage viewers to comment with their own wildest questions.

00:19Ever feel like the world is already figured out?

00:25Textbooks have all the answers.

00:27Right. We know why apples fall and how rainbows form.

00:34It can feel like all the great discoveries have been made.

00:38But what if the real magic, the stuff that makes life truly exciting,

00:45is hidden in the questions nobody can answer yet?

00:49Today, let's take a journey to the very edge of human knowledge.

00:54To the mysteries that keep our greatest minds up at night.

01:01Forget who invented the light bulb.

01:04We're asking questions so profound, even geniuses can only guess.

01:10And you're invited to guess right along with them.

01:14Let's start with the big one.

01:17Are we alone?

01:18You look up at the night sky and see a few stars.

01:22But the Milky Way alone has 400 billion stars.

01:27And there are at least 100 billion other galaxies.

01:32If every star were a grain of sand,

01:35the universe would have enough to fill millions of miles of beach.

01:40That's just what we can see.

01:43The true cosmos is likely far, far bigger.

01:48But here's where it gets really weird.

01:52Some scientists are now talking about the multiverse.

01:57Imagine countless other universes, each with its own physical laws.

02:03Some might pop in and out of existence in a flash.

02:08Others might be almost identical to ours.

02:12With another version of you.

02:15Yes, you heard that right.

02:18Quantum physics suggests that every choice you make

02:22could splinter reality, creating a new universe.

02:27In one, you aced that exam.

02:30In another, you became a professional astronaut.

02:35Some physicists say there are infinite universes.

02:39The boundaries of reality are being stretched further than ever before.

02:45Which brings us to a huge puzzle.

02:49If there are so many planets, so many potential universes,

02:54where is everybody?

02:56Our galaxy alone could have half a trillion planets.

03:02Even if a tiny fraction can support life,

03:06there should be millions of civilizations right here in the Milky Way.

03:11So, where are they?

03:14This is the Fermi paradox,

03:18named after the physicist Enrico Fermi,

03:21who first asked it back in 1950.

03:25If intelligent life is common,

03:28why is the universe so quiet?

03:32Where are the alien starships,

03:35the radio signals,

03:36the cosmic monuments?

03:39Some theories are a bit dark.

03:42Maybe advanced civilizations are hiding,

03:46afraid of cosmic predators.

03:48Or maybe they all self-destruct

03:51before they can master interstellar travel.

03:55Perhaps intelligent life is just an incredible fluke

04:00that only happened once,

04:02here on Earth.

04:04Or maybe we're just not looking for the right thing.

04:07What if aliens communicate in ways we can't even imagine?

04:14What if advanced life evolves to be microscopic,

04:19running entire worlds silently,

04:22hidden from our view?

04:24It's possible the smartest civilizations learn to be quiet,

04:28leaving a tiny footprint.

04:30Or what if the real aliens are not beings,

04:36but ideas themselves?

04:39Concepts that leap from brain to brain,

04:42evolving and shaping reality.

04:45The truth is,

04:47the universe is so much stranger

04:50and more wonderful than we can possibly imagine.

04:53The edge of knowledge isn't a boring list of facts.

04:59It's a thrilling, endless frontier.

05:03Right now, projects like SETI

05:06are scanning the skies for signals.

05:10New telescopes will soon search for signs of life

05:13in the atmospheres of distant planets.

05:16We're on the brink of discovering

05:19if we're alone or part of a cosmic family.

05:23But that leads to even deeper questions.

05:28What is consciousness?

05:30Why am I me?

05:32Is free will real?

05:35Is there a grand plan?

05:36Or are we just a cosmic accident?

05:40No one has the answers.

05:43And that's not a reason for despair.

05:45It's fuel for wonder.

05:48So here's my invitation to you.

05:52Don't just chase answers.

05:54Fall in love with the questions.

05:57Let your curiosity run wild.

06:00Because the more you learn,

06:02the more you realize

06:03how much is left to discover.

06:06Maybe the greatest miracle

06:08is that we exist at all

06:10with minds that can wonder

06:12about the cosmos.

06:13What's the biggest,

06:16wildest question you have
