Hawking Thinks Interstellar Travel Feasible

…and necessary.

Over the past several years Stephen Hawking has been calling for space colonization. His believes that once it becomes possible for a few individuals to kill millions, humanity will be faced with an existential crisis.

His solution – scatter. Once we no longer have all our eggs in this one basket called Earth, we’ll have a much better shot of surviving as a species. This is sound advice that we here at The Speculist would love to implement. The big hurdle: no warp drive.

In order to survive, humanity would have to venture off to other hospitable planets orbiting another star, but conventional chemical fuel rockets that took man to the moon on the Apollo mission would take 50,000 years to travel there, he said…

“Science fiction has developed the idea of warp drive, which takes you instantly to your destination,” [Hawking] said.

“Unfortunately, this would violate the scientific law which says that nothing can travel faster than light.”

However, by using “matter/antimatter annihilation”, velocities just below the speed of light could be reached, making it possible to reach the next star in about six years.

“It wouldn’t seem so long for those on board,” he said.

And if the ship were Orion-sized with a crew numbering in the hundreds, spinning for artificial gravity, with greenery, a voyage taking years might not be so bad.

UPDATE: I had no idea how powerful a matter – antimatter explosion could be:

The reaction of 1 kg of antimatter with 1 kg of matter would produce 1.8×1017 J (180 petajoules) of energy (by the equation E=mc²). This is about 134 times as much energy as is obtained by nuclear fusion of the same mass of hydrogen (fusion of 1H to 4He produces about 7 MeV per nucleon, or 1.3×1015 J for 2 kg of hydrogen). This amount of energy would be released by burning 5.6 billion liters (1.5 billion US gallons) of gasoline.

Err…that could be dangerous. It’s a bit ironic that the power to take us to the stars is also the reason we should go.

Time is Money

When I started Phil’s last post I was thinking: “Wow, a movie that moderates Phil’s Death Sucks position toward Leon Kass! This I gotta see.”

But by the end of the post I was left with the impression that Phil’s position is much the same.

Phil’s Stranger than Fiction spoiler ahead:

The Will Ferrell character chooses to tow the Leon Kass line – he decides that the novel’s ending will add meaning to his life that it lacked before. In so deciding, he displays a courage and a stoicism – and most importantly, a desire that his life be worth something – that is both compelling and deeply moving.

And from Phil’s comment:

[If Will Ferrell's character Crick] did it as presented — to preserve the integrity of the story — it’s a very different thing. I can’t say that I would do the same, but I admired Crick for making that choice.

I’m sure Phil will correct me if I’m wrong, but it seems that his post-Stranger Than Fiction position is, “I’ll grant that a meaningful death may lend meaning to a life that was formerly coasting along. While this fact is a challenge to my ‘Death Sucks’ philosophy, I’m looking forward to discovering how meaningful a long life, perhaps even an indefinitely long life, can be.”

Imagine we’re all living someplace like North Korea where we’re all equally miserable. Phil, being a courageous guy, publishes a pamphlet entitled “Poverty Sucks” and passes it around. I get a copy and have an epiphany: “You know, Phil’s right. This one-turnip-a-week ration stinks!” Pretty soon there’s a little movement going that gets the attention of the regime. Predictably Phil’s hauled in by the secret police.

Thinking that Phil could produce great propaganda for the state if he’s spared, Phil’s would-be executioners are told to try to convert him. So they show Phil a film montage of great paupers – Jesus, Ghandi, and many others. Then they show him films of flawed rich people – citizens Kane… and Paris Hilton. At the end of the day Phil is asked who he’d rather be like, the self-actualized poor people, or the miserable, worthless rich people.

If Phil could be convinced that those were the only two alternatives I’m sure that Phil would embrace his life of poverty and stop being such a trouble-maker. But Phil would realize that it’s a false choice.

I’ve known poor people as obsessed with money as any rich person could ever be. And I’ve also met some very mature and happy wealthy people. Money does not buy happiness, but if Abraham Maslow is correct, then people tend to forgo spiritual development until their basic needs are met. Having some money – enough to cover basic needs – provides the freedom to mature and grow that those mired in poverty might never have.

Likewise, additional time could also provide the freedom to grow and mature. And it would be a false choice to have to decide between a meaningful life and a long life. Life is not a commodity like gold where scarcity adds value. Our lives are precious because it’s what we are. That fact is true whether you’re 3, 33, or 333.

I also have admiration for those who make the ultimate sacrifice. Heroes don’t risk their lives because they hate life or think that dying at age 25 would be great.

My father-in-law was recently given full military honors at his funeral. This was many years after his military service had ended. The officer said at the grave side that “Don McFaul answered his country’s call during a time of war.” That “freedom is not free.” That “some gave all.”

I’ve thought about that last line many times since then. Does it take anything away from my father-in-law’s heroism that he survived the war? That he was not one of those who gave all? Absolutely not. Saying “some gave all” honors both those who “gave all” and those who, like my father-in-law, risked all. Death doesn’t make heroes. Death is the unfortunate price that some of our heroes pay.

The value and meaning of our lives doesn’t depend on our lifespan. That’s fortunate because we will never know – even with life extension technology – how long we have left. Our lives are valuable because it’s what we are. And our lives have meaning because of the things we do.

The Hard Stuff

Lacking the controversy of Borat and the hype of Casino Royale (hype which we have enthusiastically been a part of here at The Speculist), the new Will Ferrell / Emma Thompson film Stranger than Fiction has not received an awful lot of attention. And that’s too bad. Stranger than Fiction entertains an idea that we have largely scorned here at The Speculist: a proposition often cited by opponents to life-extension research. In fact, it’s an idea that has been endorsed by no less than Leon Kass himself.

Simply put, the idea is this – the eventuality of death gives life meaning and beauty that it would not otherwise have. In a paradoxical way, death is what makes life meaningful. So it would be a great loss, Kass and others have argued, to delay death in any substantial way. To do so is to cheapen life, and it’s just not worth it.

Up to now, you could count me among the supremely unconvinced. But this movie – that’s right, a Will Ferrell movie – has given me cause to rethink this significant philosophical question and I find that, upon reflection, my views on the subject have changed. Somewhat.

[Spoilers follow, but I won’t give away the end.]

As many of you know from seeing the trailer, Stranger than Fiction tells the story of a man (Will Ferrell) who wakes up one morning to find that his life is being narrated by someone “with a better vocabulary.” Via a mechanism never explained, he is living his life in parallel to the writing of a novel about a character who is…him. For example, while brushing his teeth, he hears the author (Emma Thompson) explaining in great detail how and why he brushes his teeth the way he does.

The whole situation is a bit of an annoyance until the moment when the narrator, indulging in some foreshadowing enabled by the third-person omniscient POV, let’s it slip that our hero is going to die. In fact, the event that will lead to his death has already occurred, although he has no way of knowing how this seemingly innocuous moment is going to prove fatal. Needless to say, the whole life-plus-voiceover situation now takes on an air of urgency that previously it lacked. Ferrell needs to find out who this woman is and get her to stop dictating his life.

He elicits the help of a literary theorist (Dustin Hoffman) and eventually the author is identified. But there’s a hitch. The literature professor reads the novel in manuscript form (the ending exists only as a sketched outline) and declares it a literary masterpiece. It all comes down to the ending. The book must end as the author originally intended or a masterpiece is lost.

But surely, in the scheme of things, a man’s life is worth more than a literary masterpiece? The glib and easy answer is yes. The film’s answer is, well, maybe. But then again, maybe not. A literary masterpiece is worth quite a bit, after all. And even if we do decide that the man’s life is worth more, we ought not to pretend that nothing has been lost in the transaction.

I won’t tell you how this issue is resolved, but I will tell you that I was impressed by how seriously these issues were addressed. The Will Ferrell character chooses to tow the Leon Kass line – he decides that the novel’s ending will add meaning to his life that it lacked before. In so deciding, he displays a courage and a stoicism – and most importantly, a desire that his life be worth something – that is both compelling and deeply moving.

It’s better to die, he reasons, and have his life count for something than go on living and have it mean nothing. (One of the interesting paradoxes of the film is that, by the time he reaches this conclusion, his life is significantly more meaningful than it was – at least to him.) That line of reasoning is the essence of the literary / aesthetic argument against life extension as summarized above.

Along similar lines, in describing the merits of actual (as distinct from virtual) parenting a while back, Stephen made the following observation:

A virtual kid would definitely be less trouble. But the trouble is indispensable to the experience. There are definitely times I’d like to pause the four-child reality at my house and leave town for a week. But I can’t. And the fact that I can’t directly effects the commitment I have to my children and, ultimately, the love I have for them. Where your treasure is – your efforts, your commitment, your time, and your money – there will your heart be also.

Whether we’re talking about our jobs or our relationships or our lives in their totality, commitments that can’t simply be turned off and situations where there really is risk involved, where something truly is at stake, are bound to be more meaningful and more real to us than experiences lacking those qualities. So I guess I’m with the buzzkills on that point – life extension may very well take some of the immediacy and poignancy out of human life. And, yes, we really will have lost something there.

I just can’t make the same leap the buzzkills do. Let’s look at another example of the same kind of thing. When air travel substantially replaced rail travel (at least in this country) and ocean liners, travel became less romantic and glamorous. We really did lose something, there, too. Of course, what we gained in the transaction made it a good deal, and I certainly wouldn’t make the boneheaded argument that air travel should be eliminated to bring the glamour and romance back.

Or let’s put it another way. If we can all agree that an average lifespan of 70 years possesses a poignancy and urgency that a 500-year lifespan might not, shouldn’t we also agree that an average lifespan of 30 years would be even more beautiful and meaningful? Isn’t it time we started rolling back the clock on sanitation, nutrition, medicine, and public safety so that people can lead more beautiful / meaningful lives?

No. I didn’t think so.

Finding the meaning in much longer lives or in relationships with nonhuman intelligences will pose tremendous challenges. How can a life be meaningful if it lacks the inevitability of death — or at least what we would think of as the inevitability of death? How can a relationship be meaningful if it comes with a Pause button? Won’t life be too frivolous and easy? Can life really amount to anything with all the hard stuff taken out?

There are no easy answers to such questions. But it’s safe to say that people faced with such choices will still take their lives very seriously, and will find that there’s plenty of hard stuff yet to go around. After all, we still consider our lives difficult and challenging, even though our hunter-gatherer ancestors might think we live in some kind of paradise. So on the question of meaning, there’s good news. Our ancestors of a couple centuries ago who had those poignant and urgent 30-year lifespans also struggled with figuring out the meaning of life. As do we. As will our offspring.

But the nice part is, they’ll get more time to work on it.

Casino Royale

If you’ve ever enjoyed any incarnation of James Bond – particularly Connery – you owe it to yourself to see Casino Royale as soon as possible.

It’s almost as if the Bond series went to rehab and purged its system of all ridiculous toxins, but Casino Royale is more than just that; it’s lean and hungry once again, as if it were totally reborn.

This one is not for children. It is a very hard PG-13. Really, it should have been an “R.” But that’s good news for anyone who is a fan of James Bond as he was originally written – escapism but with a serious, hard edge.

You Can See the Bolts on that Robot

Michael Anissimov:

The notion that we will invent AI, and then AI will reason on par with us indefinitely, is based on the assumption that human intelligence is all there is, and there’s nothing beyond it. This attitude strikes me as like that of a person in a small rural village who absolutely refuses to acknowledge the existence of any outside world.

It's a New Phil, Week 45

Here’s the promised beach photo. On the left is our good friend Justin whom we visited in Florida a few weeks back. I’m thinking the next New Phil project after the weight loss might be working on the tan.

By way of comparison, here’s a similar group shot from about a year ago, this time the two of us with my daughter Hannah:

Here’s an even less flattering picture taken around the same time. I’ve got no better-looking people to protect me in this one:
