Aliasalpha Posted February 26, 2004 Share Posted February 26, 2004 For a story that is. I'm writing a short story set on mars and I want a gravity generator that works inside the domed cities so I don't have to deal with low gravity conditions. I plan to have a scene or 2 outside the domes so I can use low gravity conditions but for the majority I want near earth gravity. Effectively want I want is magic that works only in the domes, I don't need anything super technical since I plan to gloss over it but I'd like something that's not totally implausible.

fafalone Posted February 26, 2004 Share Posted February 26, 2004 Well it would be relatively simple (and scientifically plausible) to use superdense matter (i.e. from a collapsed star, or more likely since its on Mars a new method for collapsing matter) buried reasonably far under the surface to increase the gravity...

Crash Posted February 26, 2004 Share Posted February 26, 2004 A sorta mini-black hole for finctional purposes just enough to supply HUGE gravity without crushing anything Link to comment Share on other sites More sharing options...
fafalone Posted February 26, 2004 Share Posted February 26, 2004 Dense enough to be a black hole is a really bad idea... matter can be dense enough to create a gravity field without being a black hole. Link to comment Share on other sites More sharing options...
Crash Posted February 26, 2004 Share Posted February 26, 2004 well.this is fictional dosent have to be plauseable.... "I don't need anything super technical since I plan to gloss over it but I'd like something that's not totally implausible" yea i guess i like the superdense material one the best......it leaves alot for the imagination Link to comment Share on other sites More sharing options...
Aliasalpha Posted February 26, 2004 Author Share Posted February 26, 2004 Well I'd prefer it to be plausible, the only thing I'd thought of is some kind of undreground rotating ,echanism or superdense matter Link to comment Share on other sites More sharing options...
Pinch Paxton Posted February 26, 2004 Share Posted February 26, 2004 Underground rotation wouldn't work. The dense material would work. The black hole would destroy Mars. Link to comment Share on other sites More sharing options...
Radical Edward Posted February 26, 2004 Share Posted February 26, 2004 I would go for the superdense matter thing. Or even forget about it altogether like Cowboy Bebop or Total Recall do.... but then why not just have low G on mars? Link to comment Share on other sites More sharing options...
YT2095 Posted February 26, 2004 Share Posted February 26, 2004 yeah, super dense seems the way to go. but since it`s fiction" and I`m not certain if mars has magentic poles or not, but another idea to play with might be a huge super conducting magnet in the core using the polar ice caps for the "chill factor" and each resident on mars takes a shot of a ferro-magnetic alloy that binds to cellular proteins and simulates gravity by magnetic pull, that way you can play about with the idea off worlders that havent has that shot and have seemingly super human strength and all manor of adventures can take place from there hey, it`s just a few ideas Link to comment Share on other sites More sharing options...
alt_f13 Posted February 26, 2004 Share Posted February 26, 2004 No, check this. Race track style rotating surface. That way the gravity is increased but nobody can go in the middleof the domes, just the portions that are tipped upwards. Mars' natural gravity and centripital force would work together in this case and the physics have already been proven on car test tracks. OTHERWISE Have a series of particle accellerators underneath the domes. These extremely advanced accellerators would be used to send streams of Tritium (the heaviest of the hydrogen isotopes... it doesnt really matter.. the point is its HEAVY and tritium sounds good) in circles under the domes. With the tritium reaching near light speeds it would create strong gravitational fields because of the density of the atoms becoming greater. This way you could add or subtract particles to adjust the ammount of gravity or have part of the accellerator become destroyed so only a small portion loses the gravitational pull.

mooeypoo Posted February 27, 2004 Share Posted February 27, 2004 Erm, I just finished reading a fiction story that explains some of Einstein's theories.. Isn't the only way of generating TRUE gravity (without actually greating a huge planet) is by Acceleration? ... ? Link to comment Share on other sites More sharing options...
Crash Posted February 27, 2004 Share Posted February 27, 2004 yea well what if you speed up the speed of the mars orbit and make it gain gravity that way.......you would need some serious boost for this though.........it could be done by mars gettin pushed by a explosion like a supernova up its tail but that would through it of course and we only got one sun.........

Aliasalpha Posted February 27, 2004 Author Share Posted February 27, 2004 I think I might go with the superdense matter. Hmm, there's a thought, I was planning to make a pretty major city inside the domes so it'd have the skyscrapers regular cities have (I think I've just decided to call them Domescrapers though), would the gravity extend far enough to cover the top floors? It might make an interesting scene to have lower gravity on the top floors. Link to comment Share on other sites More sharing options...
YT2095 Posted February 27, 2004 Share Posted February 27, 2004 it would be a little lower, but only by 1000`th of a gram or so. the same rules would apply there as they do on Earth if you went with super dense matter. indeed you weigh a little less ontop of Mt Everest than you do at sea level, but you wouldn`t notice it Link to comment Share on other sites More sharing options...
Duke Posted February 27, 2004 Share Posted February 27, 2004 How exactly would you obtain this super dense matter? Link to comment Share on other sites More sharing options...

The alpha is a very crude version of the symbol meaning 'proportional to'. Mass is proportional to density. Link to comment Share on other sites More sharing options...
Cheetah Posted February 27, 2004 Share Posted February 27, 2004 Duke said in post # :How exactly would you obtain this super dense matter? It's fiction. Use some kind of special fusion or compression mechanism to create very heavy materials. Link to comment Share on other sites More sharing options...
rjbowlin Posted February 27, 2004 Share Posted February 27, 2004 A different idea may be to create a magnetic field beneath the city and have everyday things doped in a given percentage of metal, cups,boots clothing. foods & drink would have to be accounted for. However g on mars is half of earths, and so wouldn't be like bouncing around on the moon. I would think it would be considerably more controlable. Perhaps diet and the like have been adjusted for life on mars. ex. water being kept in a gelatinus state. Link to comment Share on other sites More sharing options...

Crash Posted February 27, 2004 Share Posted February 27, 2004 its irrelevant to the story, but you have to manufacture it in the spot you wanted it to remain(remember this is to increase the overall gravity of mars) so its safe to say you wouldnt walk up to a star and pocket the superdense matter BTW what is the most dense stable matter at the moment Link to comment Share on other sites More sharing options...
