Back on Earth, Chris Hadfield ‘Tottering Around Like an Old Man' - Polidicks

[QUOTE=Turnips5;40682139]building a faraday cage for gravity. hey, I have a new sci-fi concept for antigravity, cool.[/QUOTE] I had basically the exact same idea while trying to write a novel a long time ago (one of the reasons I stopped was because I couldn't come up with convincing ways for artificial gravity which bugged me because I'd already sort of thought up a bunch of cool plot points that hinged on it) but I'm pretty sure I worked out that some sort of Faraday-cage type set up for gravity wouldn't be feasible for about 50 different reasons. In fact, if I'm not mistaken I think it wound up violating the conservation of energy as such a set up effectively requires 'anti-gravity' to exist (to cancel out the gravity within the cage), and you could use anti-gravity to set up a perpetual motion machine.

The gravity manipulation that i saw in some sci-fi show's deal with magnetic forces, so I think some equipment we wear like our boots help us stick into the floor and move on the floor like normal gravity, along with magnetic plating that has an on/off switch for the whole chamber, something like out of dead space or something. Just find a way to make a accessible magnetic forces, this is crucial for future generation of space ship constructions.

i do wonder if humans will ever evolve to account for microgravity, cause i want to say its going to be much more common in the future

[QUOTE=JgcxCub;40667326]I think it's really stupid that human bodies are so bad at adapting to zero-g.[/QUOTE] the human body wasn't, well, designed/evolved for space travel or being in zero gravity who fucking knew

[QUOTE=Zeke129;40681391]The space station is a zero-[I]g[/I] environment but the gravitational pull of Earth is effectively the same for them as it is for us. It's zero-g not because of a lack of gravity but because they're in a freefall. Basically they're plummeting towards the Earth but because they're moving so fast they continually miss.[/QUOTE] Yes this is correct, but I wasn't trying to explain why the ISS is a zero-g environment because of freefall. I was trying to explain why matt000024's use of the universal law of gravitation between an astronaut and the space station (ignoring the gravity due to Earth) turns out to be zero because they are on the inside of the space station, again assuming the space station is a hollow sphere, with all of its mass on the surface. [URL]http://hyperphysics.phy-astr.gsu.edu/hbase/mechanics/sphshell2.html[/URL] But of course the ISS is not a hollow sphere.

Was slightly making fun of the very pretentious members who need to make claims that can easily be factored out in a scientific study. ISS has a low enough mass and even enough size to factor out gravity from the mass of it.

[QUOTE=sltungle;40685570]I swear to god if somebody overzealously states one more time that centrifugal force doesn't exist and fails to realise that using the word makes conversation in English a shit load easier by condensing an entire phrase such as, "the fictitious force that one feels as though is exerted on them as a result of circular motion," I'm gonna fuck them up.[/QUOTE] It's still wrong and you look fucking dumb.

[QUOTE=Chilean_Wolf;40690118]It's still wrong and you look fucking dumb.[/QUOTE] No you don't because within a rotating frame of reference centrifugal force APPEARS to exist so for all intents and purposes and to fucking simplify conversations you can refer to it. It's like saying you can't fucking refer to the sun as rising or setting because in reality it's us that's spinning giving the illusion of that happening. Does it fucking matter? To us it APPEARS to be doing that, so we just say that because otherwise every fucking conversation we'd ever have would become a recap in physics (and even though I love physics, being a tertiary level physics student and all, that's not fucking necessary in day-to-day conversation). I swear to god half of my lecturers would slap you across the fucking face for that attitude. [editline]19th May 2013[/editline] I'd also like to point out that centrifugal force AS A REACTION FORCE actually does exist (however that isn't what we're referring to here).

god damn we have some smart people on facepunch
