What would happen to Mars if?

On the basis of what I have read about Mars is that it has very thin atmosphere due to weak gravitational pull so the life is not possible on it.Now my question is :

What is the possible reason for this ? is it the core of Mars, which either has been cool down or not rotating to produce magnetism? if yes then

what if a nuclear explosion is done at the core of mars will it start working again and Mars will be a planet to live upon?if yes

What type of atmosphere it will have and what type of species will evolve?

these are the few questions that came into my mind but I couldn't find the answers anywhere so here I am among the experts, only the logical replies based on scientific facts are welcome.

    Sachin, i think you just watched a Hollywood movie 'the core'....

    your doubts are not valid here bcoz it is practically impossible to travel to the core of a planet.... the temp. and pressure conditions are too high at the core... and the reason mars can't hold envelope of atmosphere is its gravitional force not EM field.....

    as riftop said, you should focus on understanding gravitational force rather than that hollywood movie concept....

    Yes, you don't seem to realize that magnetism and gravity are unrelated, as are temperature and gravity, so take riftop's advice and bone up on the basics of gravity first.

    .

    Then, you should also consider that we exploded a large number of nuclear weapons underground here on Earth, and they didn't melt the planet, so ask yourself why you think one would melt the Martian core. Granted, Mars is smaller than Earth, but so is Nevada, and Nevada didn't melt despite the many nuclear devices detonated here, so think that one through. That's assuming you could even place a device in the center of the planet to start with.

    .

    Third, even if you *could* somehow increase the gravitational pull of Mars, you still need to get that atmosphere from somewhere to begin with, right? If you can heat the planet enough then outgassing from the permafrost would contribute some, but likely not enough, so you'd still need a plan to import the balance.

    .

    "what type of species will evolve?" No one can possibly answer that. What kind of species will have evolved here on Earth a million or 10 million or 100 million years from now?

    The only way to make Mars into a world Earth-like enough to inhabit it, would be to deflect about 20%- 25% of the asteroids between Mars and Jupiter to crash into it, which would both heat up the planet and add mass to it, and then to deflect about 16 or 17 comets per second (from the cometary material belt just beyond the orbit of Neptune) for about 100 years to add enough water. That whole process would take about the next 1000 years when you allow for cooling after the asteroid hits, but you would then have to spend the next 4 or 5 thousand years making a breathable atmosphere by culturing plants and bacteria that could survive in the conditions. The increased gravity would potentially alter the orbit slightly and the increased atmospheric pressures would make it possible to retain more water vapor as a "greenhouse-gas", which would both warm the planet to an average balmy temperature of 290ºK (about 17ºC or 62ºF). The oxygen concentration would make the air almost breathable (with augmentation from small oxygen tanks) sometime after the first 100 to 800 years, and there would no longer be a need to wear pressure suits outside all the time. Some modified humans with ancestors who had the alpine adaptations of Peruvian mountain people, or Himalayan mountain guides might be able to go out without pressure suits for extended periods and without a mask but it would be hazardous. All of this effort would cause Mars to "bloom" and would provide us with a second Earth-like world in our solar system for a short time - perhaps the next 50,000 to 60,000 years without further modification. With artificial means like a ring of orbiting space mirrors, Mars could become much warmer but the need for water and atmosphere is not solvable without increasing the planetary mass and dropping comet-loads of water.

    The weak gravitational pull is due to the mass of Mars. It has nothing to do with the rotation (well, rotation does affect your weight when you're standing on it but that's a different subject), or it's magnetism.

    I would suggest understanding how gravity works first. Try Googling around and try to read up on the relationship between gravity and mass.

    Mars does have a thinner atmosphere but the reason it's inhabitable for humans is mostly due to lack of breathable air. So if you wanted to make mars a habitable place for humans without using astronaut suits, we'd have to turn the atmosphere into something more closer to what we have on earth.

    Oh and make it so it's warmer.

    Well I don't know about the gravity and what not, but dropping a nuclear bomb in a planet probably wouldn't make it very livable at the point it goes off.

    It's basically splitting matter which wouldn't be a problem in the core since it's not going anywhere, but gravity is dependent on mass and distance, so basically you'd want to add more mass to the planet, or send a person with high mass. I'm not sure about the rest of your question, but that's what I know.

    All it is happening with Mars is that at present it is an element of an extensive triangle of planets seen merely after sunset interior the western sky: Venus, Mars, and Saturn. there is an digital mail hoax circulating this 12 months because it has for the final seven years, asserting that Mars would be as vast as a results of fact the Moon on August 27. that is an city fantasy which began with an digital mail which grew to become into form of real in 2003, that Mars could be very close and vibrant. It additionally had a line in it which reported that Mars, IN A 75x TELESCOPE, could look as great as a results of fact the Moon with the bare eye. someplace alongside the way, the "with a telescope" bit disappeared. August 2003 got here and went, and a great form of persons had outstanding perspectives of Mars via telescopes provided via newbie astronomers around the realm. Then the digital mail resurfaced in 2004, whilst Mars grew to become into on the some distance factor of the sunlight. even so in 2005, whilst Mars grew to become into in opposition in October, not August, and quite lots smaller. even so in 2006, whilst Mars grew to become into lower back on the some distance factor of the sunlight. even so in 2007, whilst opposition grew to become into in December, and Mars smaller nevertheless. Now, you have been fooled via this faux digital mail in 2010! Mars is lower back on the some distance factor of the sunlight. whilst will human beings learn that astronomical activities are envisioned for a undeniable date, which has actually not something to do with Earth years, and you won't be able to easily shop recycling the comparable prediction and changing the 12 months? each thing on Mars occurs in a 26 month cycle: August 2003, October 2005, December 2007, January 2010, etc. The information: in August 2010, Mars would be very some distance far flung from the Earth. even whilst it next gets close, in March 2012, that is going to nevertheless be two times as some distance away because it grew to become into in August 2003. or perhaps then, it grew to become into purely one million/seventy 5 the dimensions of the Moon.

  • If we sent a nuclear bomb or a nuclear equivalent to an EMP into the core and or atmosphere, due to its thin atmosphere, there wouldn't be enough filtering to contain the probable adverse effects. It would grow warm to fast for the planet to begin adaptation. We would wind up destroying any possibility of life.

    1. It's a logical possibility, but it has not been confirmed.

    2. That's like testing nukes underground. The nuke would cause damage and if the planet's innards survive it wouldn't kick start it and you would have radiation in space.

    3. If it could support life, I think it would be an escape route for the people of earth or, like in Total Recall, a place for a bar and a hangout place all under a glass dome.
