The Earth is going to be destroyed and there’s nothing we can do about it.
Here’s the deal.
Bob the astronomer and Joe the programmer were working together on a new program for searching the skies for anomolous objects. Mostly by dint of accident they discover a moon sized rock traveling down from above the ecliptic and their calculations show that it’s going to t-bone terra firma in about 62 years. They quietly take their findings to NASA who have some of their big telescopes and computers confirm that yep, it’s going to suck to be us.
The PTBs decide that in this instance, ignorance is bliss and wrap a UV top secret, burn before reading and shoot yourself after reading designation on it.
Coincidentally, about 6 months prior to that, the big boys at NASA discovered that Sirius has an earth-type planet with it’s own nitrox biosphere. Spectroscopy suggests a high probability that there is at least plant life. They hadn’t made an announcement while they were firming up their research and findings.
One bright young soul with realizes that the largest brain pool available on the doomed planet is right here at the SDMB. Bonus points that we work for free.
So can we do it? Can we come up with a workable design for a generation ship that will make an 8.6ly voyage and deliver the cream of humanity to the other end?
The last of the project errata.
It is projected that the existance of the killer rock can be suppressed for 50 years.
Industrialized nations will be advised of the situation because…
Building a generation ship or ships will require global commitment. Obstacles to construction will be dealt with decisively.
The projected cover story when we begin construction will be that there’s a great planet there and we really want to go visit it. We can suggest alternatives prior to the public announcement.
We have one year to have most of a plan together. It’s understood that there will be revisions to cope with unforseen circumstances and developments and technological advancements.
grumble. have to go to work. posting this as a work in progress.
