I remember when mods would just leave threads alone unless some boobies or gore or the like showed up.

What's the point of all this interference?  This is just an internet forum ffs.

I think this is the reaction of the mods when they approve of shiat like this and then delete comments mentioning the Dread One, even if not by name:

Heliovdrake: In before the QA-Luddites


You have to admit that it's great trolling when people respond to a troll who isn't even in the thread.

We should Kickstart a campaign to send a 3D printer to Venus.

I would think it be behoove us to split these stories into two categories:

Additive Manufacturing
: The science behind building organs, rocket engines, and outer space science shiat layer by layer.

3D printing: Utopian techno-libertarians who want to have all of the plastic crap but don't want to be dependent on icky poor brown people building it.

Stone Meadow: MindStalker: FTA: NASA is developing an orbiting factory that will use as part of its ongoing search for extra-terrestrial life.

The question of how far away one could see an earth-sized object got me to searching the 'tubes. Turns out to resolve a small planet at 20 light years you'd need a telescope 13 km in diameter, or 65 km if you want to see major features like mountains, cities, lakes, etc. at that distance.

Obviously we aren't going to build telescopes that large, so what if we put a 1 km wide scope at L4, say, and another at L5, and operated them as a very long base interferometer? Would that work? Or is it more a matter of light gathering than resolution?


Yeah, I think its an issue of light gathering. If your dealing with a orbiting and rotating planet, you can't simply open up your lens and leave it open for days at a time. If you did that to earth, even if you followed its orbit, you'd have a picture of a blue blur. So to gather a snapshot in time to resolve a mountain or lake you'd need a shutter speed of probably no more than a minute or so. Then your dealing with issues of how many photons that lake sends within an area less than an arch-nanometer every minute in order to hit your telescope.

I'm Quite Astonished at the Quick Activation of that 3D printer on ISS. I suspect some Quality Antagonizing twerp will come in here and bogart the conversation like a Quackish Asshole.

Careful.

Mods shredded this thread

And we didnt even mention the luddite like you did.
