So what killed Mars Magnetfield ?

this could be done by aliens

mankind

If it is possible to influence the stability of a nucleus then half-lives are not fixed. I suspect they are not fixed.

Euh the exodus with that hole in the solarskin and gosh it looks cold the sun with those few light sparcks.

And it sais ira on the whole landscape of mars.

Mars is roughly 1/3rd the size of earth, and it doesn't have a large moon.

Earth is 'kneaded' by the moon orbiting it, the earth bulges toward the moon and away from the moon (tides). This affects not only the oceans, but the liquid center as well. All of this 'kneading' keeps the core hot.

Mars doesn't have a large moon to 'knead' its interior and keeping it hot.

Earth has more mass, the larger the body the longer it takes for it to cool off. Mars has cooled to the point where most likely its core is more solid, thus not reacting like a spinning sphere of molten metal, thus throwing off a magnetic field.

Earth is a younger planet, it has been suggested that there was a protoplasm collision (creating the moon) this reheated the earth and has lead to it being hotter now.

Spinning a liquid metal produces a magnetic field and one that switches often (magnet pole shift) and with 'ripples and eddies' much like the earths magnetic field.

Mars has a fossil field, one left in its rocks. Thus at one time it has a living core throwing off a magnetic field.

Maybe they pumped up all the oil, which is needed to lubricate the core to keep it spinning :-)

It is the spinning of the core that makes the magnetic field. When spinning stops so does the magnetic field.

So you are saying that the pull of the moon will make the core of the earth liquid ? You know the thing is the sun has higher forces on the earth why isn't it the earth then a whole liquid body ? with that much force the earth would heat itself from inside no greenhouse needed.

That's was my though about when we do this to all Uranium ?

Why do we really need this stuff only for weapons ? there is more behind it.

By the time earth core stops spinning, we have FUSION ENERGY that lets build HUGE ELECTRO-MAGNETS at the POLES, no problem :-)

Dus ..

An ex got hurted .. Dus

Thanks for posting. I've learned something today.

And my brother said when we where 19 don't do that again in the end of a windows movie maker clip with nonsense ?

....dus

Incompetent aerospace in a chain reaction. Since 1977 has been a very long time. Smirk.

.. A billion years ago and its a stinkhole atm.

Thanks for posting. I've learned something today.

1/5 of what i think ..

Oh im going to do jijij at im legend but oh no they do not have it as stupid as here ?

Yep thats what will happen to Humanity if we keep useing the same procedure and hope that our "creationism" will be over better that was here before.

Same problem on Mars as here on Earth no one wants to know whats behind balance yourself or Nature itself.

We can just build around it and hope that it will do the trick and if it doesn't then we will just remove it completely and replace it with cybernetics and robotics.

One race tried this already now they are the most hated called the "Grays".

Maggie Simpson?

The moon is closer to Earth than the sun thus has a larger tidal force on the Earth. Since the Earth spins at a far greater rate than the earth/moon orbit their barycenter, the tides moves across the surface of the earth. There is deformation of the solid land as there is of the water.

This is not enough to cause the core to turn to molten metal, but it is sufficient to nearly offset the general cooling.

If the moon was not there, then earth would be tide locked to the sun by now or close enough to where the core is not kneaded at a high enough rate to lead to maintaining the heat. Much like Venus which no longer has a liquid core, but one that has solidified.

it's something about how aliens blew up mars and the survivors migrated to earth.

I think i swallowed russian balloon planes ..

Mars is whole ... Or nm i didn't study it.

Martians to be exact. But hay, that's just my theory through speculation.

Zo , wat word je daar misselijk van zeg.

Greys ;p

Grey are a whole nother race all together.
