How can humans combat uneven gravitational field of Mars in the creation of a susutainable village on Mars?

In order to combat gravity, we would need to be able to understand what it is. At the moment, we don't. If we did, it still would be a tall order to mess with the field of a whole planet. Assuming we could "stabilize" gravity at the quantum level, whatever device we invented to do this would undoubtedly require huge amounts of energy.\n\nA much easier method would be to install a system of shock absorbers and hydraulics underneath the floor. Controlled by a computer, these could make up for some weakenings in the field and simulate to the human feet an equal field. This wouldn't actually solve the problem, just treat the syptoms. The air pressure of the cabin could also be increased to press our feet down on the ground more, but if we mess with this too much, we will implode. Also, there is the idea of placing a large verticaly aligned doughnut-shaped cabin to produce "gravity" in the form of centrifugal force, but this would be extremely impractical and require a lot of digging. I hope this helps, because until we have Artificial Gravity, there isn't really a lot that can be done. Cool question, though.

Too bad I can't vote best question for you! That is an awesome idea! I would agree that it would work because of alot less drag, but yeah, you would still have to worry about debris..But-if an entire neighborhood was dome-shaped, then there wouldn't be very much debris at all...concrete domes!

This can be solved in several different ways.  One of course is by calculus, by developing a formula for the surface area of a "slice" of the remainder of the sphere and integrating it about a rotated axis, or something similar.  Another is by digging for the rather obscure formula for the "volume of the endcaps of a sphere" and subtracting two of those and the volume of a cylinder from the volume of the original sphere (and discovering that many of the terms will cancel out nicely).\n\nThe easiest method, however, is via the use of simple logic.  Unfortunately, this method also requires one more "given" in order for it to be valid, though this given is not an unreasonable one:  There must be a single, real answer (or more specifically, a unique answer on the real number line).  Such an assumption would be folly in a practical (real-world) context, since without some form of proof, one should never immediately assume that this is the case.  Perhaps there are multiple answers, or there is no answer at all?  But as luck would have it, there actually is one answer, and it may be derived logically due to its unique existence.  (*thumbs nose at any philosophers who may be reading*)\n\nSolution:\n\nLet R be the radius of the cylinder drilled into the sphere.  If and only if there is a single, real answer, then that answer would still be the same no matter the value of R... even if R=0.  Thus, the answer is the volume of a sphere of radius 3 (diameter 6), or 36*pi cubic units.\n\n(Yes, the volume is always the same, whether the original sphere were the size of a basketball, or the size of a planet.)\n\nIt's a surprising answer, along the lines of the more familiar puzzle: "If the Earth were a perfect sphere and a band were placed snugly about its equator, and then one more meter were added to the length of the band and it were stretched so that all points along it were equidistant from the surface of the Earth, how far above the Earth would the band rise?"  Many are surprised to find that the size of the Earth plays absolutely no part in the equation, and that the "rise" is exactly the same if the sphere were basketball-sized or, umm... Earth-sized (with a circumference greater than 40,000,000 meters).  It rises exactly the radius of a circle with a 1-meter circumference: 1 / (2*pi) meters.

If an asteroid hits mars, debris is shot up and is sometimes fast enough to escape Mars' gravity. If these rocks get into Earth's orbit, there's a chance that Earth can run into these.\n\nCooldude, please edit your post and give me credit for your first paragraph.

One big adjustment is to once again get used to an environment that has gravity.  In the gravity free environment of space movement is unhindered by gravity.  Back on earth muscles have to readjust.

HOW TO LIVE ON planet earth WITHOUT decimating it !

Actually, no force is necessary to keep the earth moving in the vacuum of space.\nNewton's laws on motion cover it pretty well.\n"An object placed in motion, stays in motion until another force\nchanges it's motion". (I'm paraphrasing here but I'm sure you get the idea)\n\nIf you could float in space and throw a rock, it would just keep going in that direction until it finally hits something. As it goes by larger objects, the gravity from these objects may change the direction of the rock slightly but it would take a very large object (think planet or moon) to really change the direction of the rock dramatically.\n\nGravity is the force that simply keeps the earth in it's relative distance from the sun, counteracting the centrifugal force from our revolving around the sun, thereby keeping us from flying off in a tangent, never to be seen again.   ;-)\n\nI hope this helps you.\nGood Luck!

there are many theoretical plans to protect ourselves from impact with an asteroid. one of the most radical would be the idea that everyone has heard of, just blow it up in space. that idea consists of breaking the asteroid into to halves which pass on opposite sides of the earth. another way would be to use rocket booseters and simply push the asteroid to one side. we dont need to move it much just alter its path slightly so that it doesnt come in contact with the earth. another interesting method would be to use giant sails to catch the solar wind and like the previous idea, alter the path of the asteroid enough to not come in contact with the earth.

You would need to provide vast amounts of resources provided to earth from space and travel into space. People fight and hate for the limited resources  and wealth available.

The gravitational force holds it into a spherical shape.

I don't know what exactly is your question! If anti-gravity could be manipulated ever, i think if would be very useful for us, maybe even in interstellar travels.

The other posters are correct.  The mass of the object is unchanged.  but, the force of gravity is different on mars.  If you were standing on mars holding the object, mars would be exerting less gravity on the object than earth and thus the object would feel lighter.\n\nNewton determined that the force acting on an object is F=-GMr/r3 \n\nWhere G is the universal gravitation constant = 6.672 e-11 m^3 kg^-1 s^-2 and r is the radius (from the center of the planet) and M is the mass of the planet.  Mars is about one tenth the weight of earth, but it is also much smaller, thus you are closer to the center of mars.  The net effect is that an object feels 0.38 as heavy on mars as it does on earth.

Yes, but not in the way you might think. I don't think we'll have any of the general population living there at all. (not in 100 yrs anyway). But, I'll bet that a small team of scientists will be living on mars at that time to study and experiment how living on another planet my be accomplished.

How about a bowl of water beneath it? Is that within the rules? Alternatively one of the other posters is planning to drill a hole through the centre of the planet, you could always use their hole, it wouldn't break then!

The earth is APPROXIMATELY round due to gravitational forces.
