    As one of you has already said: finding it is one thing. Getting there is another. The original article mentioned Project Starshot--an attempt to send an automatic probe to the Alpha Centauri ABC system at one-fifth lightspeed. Trip time: twenty years. And how will they manage to stop?

    A project like this is so big, we'd sooner fight and win a war of liberation and revolution on Earth than complete this project on our own, with the Grand Looters' Collective interfering at every turn. Ragnar Danneskjöld would need to command a fleet of privateers, similar to Jean Lafitte's fleet in the early nineteenth century, and likely with ten times as many ships as Lafitte had. Three carrier battle groups might do it--and I'm talking about the new Ford class carriers, not the now-obsolete Nimitzes. (The old Big E is already in the boneyard--can't use her.) We'd need Boeing's SeaLaunch ship (if that isn't already in the boneyard, too). And even then, we're better off building a mining colony and factory complex on the far side of the Moon, where we could resurrect the old Nerva program for motive power. Then we jump to Jupiter, long enough to scoop up some hydrogen--wait. You'll need heavy hydrogen. That means landing on the dwarf planet Ceres. I have reason to believe the ices on that and other dwarf planets and large asteroids in the Belt have twice the deuterium, kilo for kilo, as the oceans of Earth.

    If we can accomplish all that, then we have the resources to build a generation ship to accelerate to 42 million MPH (at one g), coast along, then reverse heading, brake, and "inject" into the Alpha Centauri C system. Once there, our children find the planet and land. If we can trust the intelligence we have in that article.

    If we can get off the ground and make it to the moon, the interference problem vanishes. But I think here's one case where you need Hank Rearden in your community before you can even start.

    One thing you'll notice: I haven't said anything about that world already being inhabited. I doubt it would be. That red sun--life would need a yellow sun. Prepare to seed that world from scratch, if the seeds can sprout.

    Here is the irony. Even if you did have functional astral projection, you need a station at the other end first which puts you right back to having to get there first.

    Well, guess I'm all set. I hear tell that Martian princesses wear nothing but jewelry!

    John Carter got to Mars by "astral projection." All you have to do is figure that out. Get crackin', people!

    Not to be a wet blanket on the exciting news, but getting there in our lifetimes??? To get there in 65 years requires an average speed of about 42 million miles per hour. Since the speed must be attained slowly over time (to preserve very limited fuel carried on board) and then reduced slowly over time (to be able to stop at the destination), the top speed would have to be much, much higher.
    The fastest terran space craft thusfar had a top speed of 90 thousand mph, so the craft going to Proxima must travel at a velocity more than 500 times faster.
    This will require discovery of completely different (much more advanced) transportation technology, or use of the alien craft at area 51.

    Cool if true...they don't know if there is water there or if the atmosphere is breathable or not. Power up the Enterprise and we'll go check it out.
