    So I'm writing my final paper for English 1102 on the requirements of a permanent colony on other planets (food, water, air, etc.), and my research is moving pretty slowly. does anyone know of some good sources I could use?

    Reissner–Nordström black holes are craaazy. They have two event horizons and once you've fallen through both, you can stop your rocket before you get to the singularity, aim yourself, and travel to any one of countably infinitely many other universes. :O
    When you say any one, would you be able to choose which universe you enter?

    This could be of some use: http://www.projectrho.com/rocket/lifesupport.php

    In other news, the Russain space agency is planning to send a manned mission to the moon by 2030:


    Russia ialso planning to send two unmanned moon missions by 2020, Luna-Glob (Lunar Sphere) and Luna-Resurs in 2015.

    Russia is planning to send a manned mission to the moon by 2030, Russian space agency Roscosmos said on its website on Friday.

    According to the Russian space strategy published on the Roscosmos website, Moscow has set several waypoints for its space exploration activities: 2015, 2020, 2030 and the period after 2030.

    Roscosmos will resume lunar exploration by 2015 using an unmanned space ship. Russia is also planning to send a manned mission to the moon by 2030, the space agency said.

    In late January, Roscosmos's head, Vladimir Popovkin voiced plans to set up manned moon research bases with European and U.S. partners, saying that there were plans to either set up a moon base or to launch an orbital station.

    To that end, Russia is currently developing a "prospective manned transportation system" to be sent to the moon, he added.

    Russia is also planning to send two unmanned moon missions by 2020, Luna-Glob (Lunar Sphere) and Luna-Resurs in 2015.

    The launch timeframe, however, may be reviewed because the two spacecraft are being built with the same technologies as Russia's failed mission to Phobos, which proved vulnerable to cosmic radiation.

    The moon base project has similarities to Cold War-era plans to create a permanent outpost on the moon, which has been envisioned by some Soviet and U.S. scientists since the late 1950s.

    Yep, each universe has a white hole from which you can exit and black hole from which you can enter and move on to the next universe. It's not like a room where you stop look around and pop out in whichever one you want, but you can go into any one by going through them in sequence.

    I don't get it. Does every solution to the field equations yield black holes with different properties?

    Not in general but if the solutions account for different things they can have more exotic properties. Reissner–Nordström is the solution for non-rotating, charged black holes.

    It's a shame but a lot of black hole stuff is purely theoretical. We actually still don't know if singularities exist at all or if they're an artifact of the highly symmetric cases we solve exactly.

    hey, speaking of crazy-ass space movies, anyone else seen Love?


    Trippy film about a single astronaut sent up to the old ISS to retrofit it for new occupants. While he's up there, a nuclear war breaks out on the surface, and he's left stranded while the rest of humanity wipes itself out. He starts going insane shortly thereafter.

    Plus, all music by Angels and Airwaves.


    Awesome film. Every copy comes with the full soundtrack.

    Looks interesting but there's not supposed to be gravity on the space station. That would bother me the entire movie.

    But they could retcon it by saying before the ISS was abandoned it was fitted with a gravity module.

    Because that's how science works

    Speaking of gravity and ISS. There is a plan to launch thing thing to simulate gravity inside the circle.

    That would have to rotate really fast to make any gravity worth mentioning.

    When it's over 2 RPM most people are gonna get sick from it, and the faster, the harder it is to adapt to it.

    That think looks no more than 10m in diameter, but let's assume it's 20m in diameter, that would require almost 10 RPM to get 1G.

    It's a very interesting concept though, and it would be neat to see it tested.

    Hopefully they'll get something like that up there before they kill off the ISS.

    (Btw, you'd get moon-like gravity with a 20 m diameter and 4RPM)

    I should have added more info. Anyhow it's supposed to be part of the Nautilus X space craft.

    http://en.wikipedia.org/wiki/Nautilus-X

    So the most obvious way to test out that ring is to attach it to the ISS. However there hasn't been much info about that. So it may or may not have been cancelled.

    There are two proposed diameters, 30 ft and 40 ft. At max RPM (10) the 30 ft rings gives 0.51g and the 40 ft ring gives 0.69g.

    I don't think it would be any less nauseating than flying around in microgravity. The only force acting on the bodies within the torus would be a 'downwards' force which is exactly what we experience on Earth. Provided there's no outside reference for you to look at to make you dizzy, it'd be fine.

    No, there's a Coriolis effect that makes it difficult to live in it if it has more than 2 RPM.

    Yeah but aside from 2001, Sunshine and maybe Alien, it's all bulky, convex battleships and shit.

    One thing that always gets me is that very few creatives seem to grasp how space works. Ships are always directionally-designed boats rather than something that takes advantage of the unique properties of space.

    I mean, the fucking Borg Cube makes more sense than an X-Wing or a Battlestar or whatever. You don't need a front and a back on a space ship, you just need something to give it maneuvering and momentum. Most of the stuff has, for instance, decks like you'd expect on a naval vessel.

    Where we're going, we don't need floors.
