Why Cant We Terra-form Mars?

like futurama did
send some water out there and some protection from the thin atmosphere (or is it thicker) whatever the differences are. let some micro-organisms form and then the rest is waiting and keeping the life alive
why not?

i'm pretty sure it's a lot more complicated than that. not saying it's not do-able though.

If we dont start soon we are gonna have to terra-form mars to have a suitable place to inhabit.

It should be possible but not "like futurama did" If you place some genetically modified arcae there and wait a couple of tens of thousands of years you could get something that could be terraformed further...

Mars is quite far away man.
We could in theory,, we'd need to pollute the place first to create a decent atmosphere but we're good at that.

Would a very quick evaporation of the frozen water present at mars' poles create some sort of atmosphere that humans could breathe?Or would nitrogen and other elements need to be present.

Not sure,, don't know if that would release enough oxygen.. You would need some kind of global warming to melt the caps though..
I think our caps help regulate the weather and other stuff so god knows what Mars would be like without them.

mars has poles... theres just not ice at them.
I reckon theres a very good chance that there is water on mars.. or if not water some other hydroxide.. like h2o2 or h(1+)o2 or something Surely that could be converted into water easy enough?
after all hydrogen is the most abundant gas in the universe..

Mars does have ice at atleast one of its poles.Frozen H20 that is.

Or maybe not.
"Boynton is the principal investigator for a suite of instruments onboard Odyssey collectively known as the gamma-ray spectrometer or "GRS." The GRS has been mapping Mars since February 2002 and has detected telltale signs of water ice in the upper meter (three feet) of soil in a large region surrounding the Red Planet's south pole. It may be better to characterize this layer as dirty ice rather than as dirt containing ice," notes Boynton. The amount of hydrogen detected corresponds to 20% to 50% ice by mass in the lower layer. Because rock has a greater density than ice, this amount is more than 50 percent water ice by volume. This means that if one heated a full bucket of this ice-rich polar soil it would result in more than half a bucket of liquid water."

Hmm well a good place to start is what is gravity?
I have been asking this question for along time, and not many people have come up with satisfactory answers. Heres an idea thought, on the forefront of theoretical physics:
Gravity is a curve in space time, and because of this curve, larger objects attract things to it. Imagine a bowling ball on a rubber mat suspended in air. The ball causes the mat (which represents space time) to curve. Now place a smaller object on the same mat, such as a pin, the pin rolls towards the bowling ball, no?
This is one theory of what gravity is (very very very simplified).
Now, just because mars doesn't have an atmosphere doesn't mean it doesn't have gravity, however, mars is smaller than the earth, so there will be a smaller downwards force acting upon objects on it.
Mars' gravity is about 3.8ms^-2 which is about a 1/3rd of the earths.
As for creating gravity.. well there are several hypothesized ways: You could spin the object in question to such a degree it creates a centrifugal motion, creating gravity (I don't think that would work on a planetary scale)
Accelerating the object.. similar to the above "forcing the objects inside the vessel to go in the opposite direction of acceleration"
Or Creating a superdense core, to 'weigh' (I use the term loosely) the object down.
http://en.wikipedia.org/wiki/Artificial_gravity
I don't think this is going to happen any time soon though

Does time change when things get closer to denser objects/objects with more gravity?Does the passage of time speed up the closer you get to something like a blackhole or a white dwarf?I guess its all in the concept of what time is and if it is linear,circular,non existant or what.
Is light affected by gravity or as you put it,this bend/curve in space and time?I assume so.I have not taken any college physics classes though.
Your simplified explanation of gravity intrigued me.

It will take hundreds of years for this to happen.
Humanity at this point does not have the will to do something like this.
If we make it to a type I or II civilization perhaps...
We're type 0 right now.
As for the black hole, doesn't time become infinity at the singularity? I don't know anything about this sorry...

The passage of time is affected by gravity or the presence of a mass, but it does not speed up - it slows down. This effect has been experimentally proven by measuring the time difference between the bottom of a skyscraper to the top.
The effect is very small here on Earth, but it becomes large near things like black holes and neutron stars. Time in effect stops at the event horizon of a black hole.

Yes light is affected by gravity by bending towards the gravity. This has also been experimentally proven, and was in fact the proof that sealed the deal on Einstein's theory of relativity.
If you are wondering what the proof is, they measured the distance between two stars at one point in the year, then measured it again when the sun was between the two stars. The stars appeared closer together when the sun was between them - evidence of gravitational bending of light.

One point I can think of that hasnt been mentioned is the lack of magnetic field. The earth has the strongest magnetic field of all the terrestrial planets. This protects us from cosmic rays (solar wind, radiation, bad stuff etc). This magnetic field is created at the core. Earth has a very active core, Mars does not.
Unless you want to live in domes with very thick walls (many feet thick), you will have to somehow construct an artificial magnetosphere.

The deal has not been sealed, nor will it ever be. Science is not capable of sealing deals. I know its petty... but I had to throw that in...
