We're Hardly Alone in the Universe 7/5/2006 by Mark P. Shea Bible Study and Truth Tracts Author One thing I have discovered (to my surprise) is how shocked some folks get when I express my opinion that we humans are never getting off the earth in any serious way. We're Staying Right Here on Earth Oh sure, we might get a couple of people to Mars to walk around. Maybe a long-term space station with more than a handful of astronauts in near-Earth orbit. Maaaaaaaybe a moon station. But we're never, I think, going to colonize the planets. And we're most emphatically never going to go to another star. This earth is pretty much it. We must learn to face the fact that the frontier period is past and we ain't going anywhere. These are not, by the way, religious opinions. They are opinions based, not on my theological views, but on cold, practical considerations about things like "what it takes to get there." I'll be willing to change my opinion when we establish a thriving metropolis in Antarctica, which is infinitely easier than establishing a serious, self-supporting colony on Mars or the Moon. Rare Earth Similarly, to devotees of SETI and the quest for extraterrestrial life, I say my mind is strongly persuaded by a book called Rare Earth that the assumption of a densely populated cosmos is all wet and that intelligent (or even multicellular) life is a lot rarer than you'd think from watching Star Trek. In short, I think that we are, for all practical purposes, all alone. If there's somebody out there, we'll never know it, because the odds are that intelligent physical life is so remote from us - if it exists at all - that we can't hear it if it is broadcasting electromagnetic signals. Again, I say this not due to my theological views, but because the science is on my side. As Rare Earth demonstrates, over 20 factors all have to line up just so in order to even have a shot at intelligent life arising on a planet. The odds against all those factors working out with such fine tuning are extremely slight. So the odds of life existing in most of our galaxy are likewise extremely slight. Indeed, the vast majority of stars in the Milky Way cannot have inhabitable planets, since they are concentrated in the center, where stellar radiation makes the chemical conditions of life impossible. Secular Eschatology Why this digression on science? Because while my views are not theological, what I discover is that the faith in ET and our eventual trek to the stars is deeply theological with many people. Very typical of what I mean is the remark made to me by a friend a few years ago: "As thought experiments go, speculation about extraterrestrials have been (for me, anyway) a devotional exercise." And not just for him. Note this weirdly eucharistic anecdote about science fiction writer Kim Stanley Robinson from the Chicago Tribune: In the middle of writing Blue Mars, [Robinson] recalled, he took a small Martian meteorite he had purchased from a dealer and climbed to the roof of his home. At sunset, he popped the tiny stone into his mouth and swallowed it, hoping that having a piece of Mars inside him would enhance his creative process. Communing with the Real Presence of our Great God and Savior, Mars Ares. Nope. Nothing religious going on here. This is why the longer I live, the more persuaded I become that aliens fill, in a secular age, the imaginative and emotional niche that was once occupied by angels and demons just as Our Destiny in Space fills what used to be the Christian hope of our Destiny in Heaven. It is, I think, a profound illustration of the fact that our hearts are God-shaped vacuums, sucking in whatever comes to hand in the search for God or His nearest approximation. Hope or Despair? Some will argue that Christians "fear" the notion of contact with ET because it will definitively remove us from our "privileged" position as children of God and show that we are but one of many intelligent species throughout the cosmos. But this simply goes to prove my point about the way in which angels and demons have receded from popular imagination and left a void. For the trouble with this criticism is that the Christian revelation already tells us there are myriad intelligent beings throughout Creation. That is, after all, what angels and demons are. So I see no reason that finding ET should trouble us as Christians. I merely think that there is plenty of scientific - not theological - reason to think that such biological creatures will never be found. Colonization of the stars and contact with ET (sort of) fills the void left by modernity's abandonment of the true eschatological hope of the return of Christ. Sooner or later, it will become evident to secularists that this hope is as chimerical as the Marxist hope of the Withering Away of the State. I wonder whether that will prompt a return to Christian hope or simply lead to final despair?

We must learn to face the fact that the frontier period is past and we ain't going anywhere. I suppose as you presumably agree with Intelligent Design you would consider a Von Neumann machine impossible. That is a necessary (and largely sufficient) condition that has to be met before space is colonized. BTW - Do Evangelical Christians have any definte views on IKEA and robotic flatpack assembly. - A vital first step. These are not, by the way, religious opinions. They are opinions based, not on my theological views, but on cold, practical considerations about things like "what it takes to get there." I'll be willing to change my opinion when we establish a thriving metropolis in Antarctica, which is infinitely easier than establishing a serious, self-supporting colony on Mars or the Moon. Thety are based on ID and on the impossibilty of us achieving self replication. Of couse VN will be intelligently designed - BY US!

Indeed, the vast majority of stars in the Milky Way cannot have inhabitable planets, since they are concentrated in the center, where stellar radiation makes the chemical conditions of life impossible. Secular Eschatology I don't believe it is. Science tells us - my pet subject is AI as you probably all know, that a UFO visit to Earth is virtually impossible. Not for any reasons that it is inherently impossible, but because of the way in which our science and technology is advancing. Not for reasons that Earth is rare. It may be, but we do not know for sure. My stock reply to UFO buffs is now "!puerde lectar en espagnol!" This simply means that AI (their's) is doing the postings - in all languages. Is SETI a waste of time? It probably is, but again for different reasons. If ET REALLY wanted to communicate with us he would find a way of doing so. If he did not he would make damn sure that powerful encryption was used and we saw only a noise signal. Why this digression on science? Because while my views are not theological, what I discover is that the faith in ET and our eventual trek to the stars is deeply theological with many people. Very typical of what I mean is the remark made to me by a friend a few years ago: "As thought experiments go, speculation about extraterrestrials have been (for me, anyway) a devotional exercise."

At sunset, he popped the tiny stone into his mouth and swallowed it, hoping that having a piece of Mars inside him would enhance his creative process. From a religious perspective the absence of life is a rather mixed result. God has created a Universe of (at least) 80 G Parsecs with life only on one planet. What a waste! If we colonized, the earth being 4.55e9 years old means that we might have a comperable period ahead of us. That is if we are not silly. We will certainly send VN probes throughout the Galaxy.

It is done as a help to understanding the Universe in which we live. - Ian Parker |

That is a necessary (and largely sufficient) condition that has to be met before space is colonized. No, Ian, it's not. Space can be colonized just fine without any Von Neumann machines (and I sincerely hope it would be -- even if such technology is developed, it should probably be banned, or at least tightly regulated). I am talking about MEANINGFUL colonization. Not just a few people living in expedition conditions. We also ought to look at timescales. 10 years for IKEA. If you have CAD/CAM specification true VN is not far away. The question of Intelligent Design is in itself interesting. "Religion is the opiate of the people" proclaims Marx. Yet Marxism has at its core a belief in ID. "Only workers can create value". This to me precudes a VN machine and constitutes an ID statement. If chemicals came together 3.8 billion years ago and created a closed loop we can create a closed loop now (in fact all that is required for a closed loop is CAD/CAM). I would be interested to know how ateism views Marx. Is he totally repudiated? - As he should be. The basic igredient for interstellar travel (assuming that warp drive is impossible - as I personally believe it to be) is a system of phased lasers propelling a spacecraft with a sail. One further point about ET. People are taking of memory cubes by 2020. Perhaps optimistic, but molecular memory the size of a sperm contains 4GB (a DVD). Clearly GENUINE flying saucers could be very small. This is why antimatter is a perfectly feasible method of braking. - Ian Parker |

"Only workers can create value". That's a nice non-sequitur. An economic statement has nothing to do with religious beliefs. It may well be true that this statement of Marx has nothing to do with Intelligent Design... This to me precudes a VN machine and constitutes an ID statement. You have a very strange outlook, then. ![]() is created by the efforts of workers (including workers who build and maintain machines, of course). This in no way, shape, or form implies a belief that the universe was created by an intelligent designer. But Marx was still wrong. Of course workers do create value. But it isn't *only* workers who create value. Raw materials have value. Capital - tools, facilities - have value. They make it more efficient for workers to create value, so they're worth something too. What Marx was going on about was that since only workers *spend* the money they're paid right away, if some of the money paid for goods and services goes to the owners of natural resources or factories, then there isn't enough purchasing power in the hands of consumers to buy the things produced. This was the theory of surplus value. The pros and cons of which I won't get into, this being far enough OT as it is. John Savard |

Strout made the phosphor on my monitor glow in such a way as to indicate that: In article .com, wrote: No, Ian, it's not.

If you have CAD/CAM specification true VN is not far away. I respectfully disagree. Why would you have any respect for ianparker? |

Have you looked at the size of chip factories lately? This is a good point. However we may not start off with a complete VN machine. We may well send chips to the Moon even if we don't have to send anything else. There is one other thing which will probably be kept on Earth - At any rate until there is interstellar travel and that is the basic genome. - Ian Parker |

Even Marx knew it by the time he died. 'Value' is essentially a market fiction that wanders around with supply and demand. The expenditure of labour has nothing to do with 'value'. -- "Ignorance is preferable to error, and he is less remote from the truth who believes nothing than he who believes what is wrong." -- Thomas Jefferson |
