PART 8 of MICHIO KAKU INTERVIEW

Imagine you're in a room and many radio frequencies are in the same room. Your radio is turned into one frequency but you're very comfortable being in a room with many frequencies, right? But you tune into one.

Well these frequencies are now wave functions.

In this room there's the wave function of dinosaurs.
In this room... because they never died 65 million years ago!
Because a cosmic event prevented the extinction of the dinosaurs!

In this room, there's the wave function of aliens, because perhaps aliens decide to colonize the Earth millions of years ago.

In this room, there's the wave function of Alexander the Great, perhaps he came all the way to the Americas instead of being... just conquering most of the old world.

Think about it.
Your mind goes crazy!

This is the multiverse. So, Welcome to the multiverse.

We now believe that perhaps there are infinite number of universes out there.

Most of them probably dead universes, but some of them may be separated from our universe by a single quantum event.

The smallest quantum event is a cosmic ray.

Let's say a cosmic ray goes through Hitler's mother. Hitler's mother has a miscarriage. Hitler is never born. All of a sudden, perhaps 40 or 50 million people didn't have to die and they're living with us today.

Or perhaps a cosmic ray went through Roosevelt's mother, and Roosevelt never roused the American people to oppose the forces of the Axis, and I'm speaking German today and there's a swastika behind me right now.

I mean, one quantum event separates us from these parallel worlds!

Now some people ask me the question, well, Professor, if Nobel laureates are even arguing about this, then the question is: is Elvis Presley still alive in one of these universes?

INTERVIEWER: Many would say yes.

KAKU: Well, believe it or not, there are physicists at oxford university, David Deutsch, for example, who would say, yes, there's a universe where the King is still alive.

INTERVIEWER: Wow, we've got some things to think about... We're blown away, we act like it's such a phenomenon if our dead Aunt Lily talking through a medium to us and you're talking about many different potential...

KAKU: Nobel laureates argue about this question.

This is one of the greatest unresolved questions in all of physics. Physics is fantastic, it's incredibly accurate, but it's based on the cat. And at the present time, there's no consensus on the cat problem.

There are hundreds of physics conferences. My friends attend these conferences. Physicists yell at each other, they scream at each other. Because what is at stake is reality itself. The nature of existence... that is what is at stake.

INTERVIEWER: Professor, thank you so much for taking the time.

KAKU: My pleasure.

NARRATOR: His newest book, Parallel Worlds, focuses on the newest multiverse theories. I also loved his book, Visions, which extrapolates what our lives will look like fifty, a hundred, a thousand, and even more years into the future. Like this interview, his writing is wonderfully entertaining. You can look at a complete section of his work on his website listed beside his name on the menu.

Until next time, thanks for watching.
