You've got to love the audacity of this idea. In a recent article at Discover Magazine, virtual reality pioneer Jaron Lanier (you know, the guy with the dreadlocks) proposes that we get working on repositioning nearby stars to form geometric patterns - or at least start looking for places that it's already been done by [...]

I liked the idea of moving entire solar systems in Larry Niven's books.

The Puppeteers would magnetically pinch the corona of a star to form a jet and over time just take the entire system wherever they wanted it.

Given the energy required to tow stars around, if you're trying to get some attention, wouldn't it be easier to dump hydrogen on a star and have it nova out some prime numbers?

Wait, I can make out a message! It says...

"I Love You, Leela"

...Nope, it's gone.

Note that the system described in http://home.comcast.net/~mbmcneill7/ could develop the light speed capability to deflect asteroids with several times the mass of the one that is alleged to have contributed to the demise of the dinosaurs as well as move stars with their planets. Once you develop the ability to move stars, with coordinated effort you can move galaxies, then groups of galaxies, then engineer the expansion of the universe. The most difficult problem may be the attention span of the human species which must remain focussed over millions of years.

Fraser. Even more absurd than the dark matter authors. If & when "they" exist and want to visit...it'll be because we're a G-3 planetary body in the habitable zone for ole Sol, and with water vapor, CO2, O2, and CH4 in the atmosphere, and a varying albedo....a good candidate. When the Canadian & Siberian tundra thaws and starts emitting methane bigtime....an even better candidate. Who hires these journalists? pete

1. State why it's "absurd".

2. A good candidate for what? Habitability for beings who evolved only under those conditions?

Noclevername. 1. Fair enough. With our limited resources as a race, not just a nation, I doubt that moving a few objects with ~ a million Earth masses, to line them up and spell "donkey", or "two"...is high on the list. The energy budget alone is absurd.The money and resources can be far more productive exploring the solar system, building that base on Ceres or Mars that so many are interested in, or sending the probe to Europa's frozen oceans. How about terraforming Mars?
2. As the biosphere is a hugely diverse ecosystem capable of adjusting to multiple variables simultaneously, we are presently a good candidate for settlement or trade for other sentient civilzations, and ourselves, lifeforms, having arisen through social interactions might find competition in so many modes eventually, chimps, gorillas, octopi, porpoises, birds, meerkats. Ventners oceanic voyage found ~ 70% new species. New species evolve every day even as others go extinct by C-14 slowly mutating genes....and the environment inexorably selects. What a fabulous planet, and we should have the brains and the foresight to see that it is not all put at catastrophic risk to impacts, or "Omega Strains", or worse...but to extend our diversity throughout the solar system and beyond. So should other civilizations if they are out there. Real star-trekking, not the Hollywood stuff...and it's going to take chutzpah, bigtime chutzpah. pete

As we're discussing a far-future scenario, not our present capabilities, that's irrelevant. Once we have the necessary automated manufacturing technology and open access to space, arbitrarily large projects can be accomplished. Our energy and material resources will no longer be limited, but open-ended.

You are assuming their idea of a "good candidate" and a "fabulous planet" is the same as ours. No basis for that assumption.

A line of stars would be interesting for a series of gravity assists...

I propose moving the stars to the shape of something easily recognizable, say a dipper. And make a second smaller one just to be sure they get the message.

How about they arrange the stars in their galaxy into something highly visible that can be seen for millions of light years. Perhaps a regular spiral shape? Then everybody else does the same with their galaxy to show they got the message ;-)
