Cosmos: Possible Worlds

De: Ann Druyan

Narrado por: Ann Druyan, Jennice Ontiveros

This new and long-awaited sequel to Carl Sagan's international best seller continues the electrifying journey through space and time, linking worlds within and worlds billions of miles away and envisioning a future of science tempered with wisdom.

Based on National Geographic's internationally renowned television series, this groundbreaking and visually stunning book explores how science and civilization grew up together. From the emergence of life at deep-sea vents to solar-powered starships sailing through the galaxy, from the Big Bang to the intricacies of intelligence in many life forms, acclaimed author Ann Druyan documents where humanity has been and where it is going, using her unique gift of bringing complex scientific concepts to life. With evocative photographs and vivid illustrations, she recounts momentous discoveries, from the Voyager missions in which she and her husband, Carl Sagan, participated to Cassini-Huygens's recent insights into Saturn's moons. This breathtaking sequel to Sagan's masterpiece explains how we humans can glean a new understanding of consciousness here on Earth and out in the cosmos - again reminding us that our planet is a pale blue dot in an immense universe of possibility.

Simply terrific!

In the continuation of Carl Sagan’s Cosmos legacy Anne has done an amazing job bringing this new batch of science, history, and entertainment to the next generation. Wonderful insights and perfect narration makes these 10 or so hours fly by.

HIGHLY RECOMMENDED

pleasure to read

it was a pleasure to read. I really enjoyed the personal side of the story. wonderful book. highly recommend

Legend of Sagan

The torch of knowledge passed by Carl continues to shine bright in all of us

Beautiful and poetic; I wept several times

I love the original Cosmos more than just about anything in the world.

Ann does a superb job trying to captain the ship all by herself. And in truth she isn't alone. She had feedback including from her son Sam.

Hits the mark:

* Poetry and cosmic perspective; I wept several times
* Inspiring, relevant stories from the history of science

Misses the mark:

* Critical thinking and skepticism
* Scientific and historical accuracy

For example, the section about quantum mechanics gets a few things wrong.

1. It's implied that "free will" is a challenge to quantum super-determinism, which it's not. First of all, we can't start out by assuming our intuition that we have free will is correct. It's not. Libertarian free will is incoherent, even in an nondeterministic universe.

2. It's claimed that entangled particle pairs "communicate" with one another which is incorrect. There's a coincidence between their measured spin on a given axis, but that's merely a perfect correlation. Bell's inequalities show this doesn't arise through any "communication" as typically understood. Instead, it's just how the universe works. We can't use this to communicate faster than light, because knowledge of the coincidence has to be transmitted along some classical channel. This isn't me being pedantic. Her point was that the universe is spooky and allows for faster than light communication. Which is wrong.

3. It's claimed there is "no objective reality" under quantum mechanics. It's not even very clear in the context of the chapter what justification she intends to support this claim. It's just not true. There's nothing subjective (as opposed to "objective") in QM. There's nothing surreal or unreal as opposed to plain old "reality". Certainly the theory doesn't have local realism, which might be what she was getting at. But she goes on to use it in the context of spookiness about there being no objective reality, which is clearly antithetical to QM, which is a well-established physical theory of an objective, external physical reality. I don't forgive this as poetic license. Unfortunately, she was just lying.

But in the whole book these are the only three mistakes I found. That's not so bad.

Enlightening and Wonderful

I grew up with “A Personal Voyage”. “A Spacetime Odyssey” after all those years was a little miracle. “Possible World” is a magnificent explosion of science, endeavour, and hope in our future. We owe Steve, Carl, and Annie so much!
