Michio Kaku: The Future of Humanity @ Talks at Google (Transcript)

And for the most part, what do we have to offer them? If you’re going to a forest and you meet the deer and the squirrels, do you talk to the squirrels? Initially, yeah. Good boy. Yes, you talk to the squirrels. But then you lose interest because they don’t talk back to you. And even if they did talk back to you, do they have a preemptive strike by throwing acorns at you?

So I think that on that scale, if they can reach us from another star, they’re already type two, or more than likely, type three.

AUDIENCE: Do you think we will ever leave Earth forever?

MICHIO KAKU: I think at some point, we may have to leave the Earth forever. In five billion years, the sun will expand. The mountains will melt. The oceans will boil. The sky will be on fire and we will have the last nice day. We have to.

Five billion years from now — it’s the law of physics. Physics is a death warrant for intelligent life. And in fact, 99.9% of all lifeforms go extinct. How do we prove that? Just dig right under your feet. Right under your feet are the bones, the bones of 99.9% of all species that have ever existed on the planet Earth. Extinction is the norm for life. We forget that.

Extinction is the norm. We have a brain. We can control our destiny, but most animals cannot. And so we forget the fact that extinction is the norm. So it’s not a question of if, it’s a question of when we leave the planet Earth.

There’s no choice. It’s the law of physics.

FEMALE SPEAKER: Thank you all so much for coming. That’s the end of our talk. And we are just so grateful to have had you here. Thank you, so much.
