What if we bomb the mars`s core?

[Roadam]

I was thinking. Mars has wery weak magnetic field, and the theory is that the field exists becouse there is liquid core, and Mars is supposed to have mainly solid core. What if we drill deep into mars and blow a few thermonuclearfusion bombs to heat it up? Would it cause to strenghen the magnetic field and would it be feasible? If it could it be used on moon....

The bolded phrase is incorrect. :hihi: While a magnetic field persists on Mars today, its source is wide deposits of magnetized rock, not a molten core. A molten core is postulated to have once existed on Mars however, which accounts for the now magnetic rock.

We have no plans to 'blow a few' nukes on Mars.:shrug: :eek2:

[Roadam]

I was just trying to ask if we would with moltening the core induce magnetic field. If the magnetic field of earth is consequence of liquid metals in the core.

 

And I know that magnetic field on Mars is becouse of that magnetized metal plates. I was just doing wikipedia research.

Might be better to try slamming something REALLY big REALLY quickly into the surface. Just a thought.

You would have to drill down about +3000km thats a very long way - then if some sort of bomb would heat it up, you would need to have them in different places ie more drilling around the planet - then if these bombs dont blow it to peices it will still end up cooling down again. All this aside, I dont think it will even give mars a magnetic field just having a liquid core alone. I think it also comes down to currents of the liquid core.

[Mercedes Benzene]

The fact that a magnetic field exists is not because the core is molten and in motion, but that the moving, molten core is made of METAL.

Since it is theorized that the earth's inner core is solid iron, with a flowing metal outer core around it... then:

The spinning motion of the metal around the iron creates a magnetic field.

This is the same principal as generators that we use to create electricity. The metal spinning around the other metal creates an electromagnetic field...

 

That's the way that I have always seen it...

...then again, I am not a geologist.

There is a model that has recieved very little attention, which I think is probably valid, that the core of the Earth is acutual a veritable Fission or Fusion reaction.

[Jay-qu]

really? I dont think so.. for a start hydrogen is the most easily fusionable element, and our core is made of heavy metals.. not even our sun has the energy to fuse this stuff. Fission, maybe, but I still have my doubts

Natural Nuclear Reactors

 

Since the 1970s, geochemistry has documented the origin and existence of naturally-occurring slow fission reactors in uranium-bearing geologic formations at Oklo in Gabon, Africa. The Oklo natural nuclear fission reactors operated over 2 billion years ago, when the natural occurrence of the uranium-235 isotope (required for the fission chain-reaction) was much higher.

[edit]

 

Planetary Fission Reactors

 

Large, gaseous planets, such as Jupiter, radiate more energy into space than they receive from the Sun. (In the case of Jupiter, the radiated energy is almost twice the received energy.) The source of this energy is conventionally attributed to gravitational contraction, since gravity seems to be the only force sufficient to account for the quantity of energy released. In 1992, Dr. J. Marvin Herndon, an American nuclear geochemist, postulated that the excess energy could be explained by the existence of a central nuclear reactor. High-density fissile elements (i.e. uranium) would be concentrated at the core and the extreme pressure and temperature at the planet's core would initiate the reaction. Herndon tested this hypothesis using calculations similar to those used in nuclear-reactor design and found that planetary-core natural fission reactors were feasible.

 

One thing to keep in mind is that Fission and Fusion are about resonance. It is a common misconception that you HAVE to have high energy particles bouncing around. That is where the concept of Cold fusion came from, was that in theory if you got the right combonation of harmonic atoms together they would spontaniously resonate and fusion into another atomic state.

You are VERY RIGHT!

A lot of people simply do not know much about nuclear chemistry... but KickAssClown is right!

Props to you!:)

[Jay-qu]

ok even taking this into consideration, I hear our core is made of Nickle. Nickle is heavier than Iron, anything past Iron when fused actually takes energy not releases it. So why isnt the core rapidly cooling?

[IDMclean]

No clue, I haven't researched the topic extensively, it just is intuitively correct to me.

Planetary Fusion Reactions

 

In seemingly unrelated work, Steven E. Jones of Brigham Young University has speculated on the existence of natural fusion reactions at planetary cores, continuing work initiated by Dr. Paul Palmer (also of BYU) in 1986. Their initial work was also focused on explaining the excess heat given off by Jupiter and then extended to include possible application to Earth. The term geo-fusion is used to describe their theory. Geo-fusion is a form of cold fusion (Although geo-fusion is not the type of room-temperature fusion described by Stanley Pons and Martin Fleischmann, Jones was working on muon-catalyzed fusion and was intending to publish his results simultaneously with Pons and Fleischmann, at the nearby University of Utah, when they "scooped" him with their public announcement). Jones hypothesizes that geo-fusion is driven by the high pressures present at planetary cores. Jones has suggested that measurements of the levels of tritium released by volcanic processes may provide a possible confirmation of the theory.

Criticism

 

Dr. Herndon's theory is not accepted by most geologists. However, Rob de Meijer and associates at the Nuclear Physics Institute in Groningen, the Netherlands, have proposed an experiment to measure the antineutrino flux from the Earth's core which they believe will validate Herndon's hypothesis. At present they are seeking funding for the project, which involves development of an underground laboratory in Curaçao.

 

The following is taken from a San Francisco Chronicle article by Keay Davidson describing that test[1]:

 

One of Herndon's leading critics is planetary scientist David Stevenson of the California Institute of Technology. He says in an e-mail: "Herndon is a solid and knowledgeable person when it comes to (nuclear) reactors. But the amount of attention this (georeactor) idea has received is out of proportion with its plausibility. ... It's not complete nonsense, but it's highly unlikely. There are many instances in science where this happens. This one has merely received more attention than most.

 

"The idea is based on two very dubious propositions: (a) That uranium (or any heavy element) would naturally go to the center of the Earth. This is almost certainly untrue. It is a misunderstanding of chemistry and statistical physics at a very fundamental level. (:lol: That there is something about Earth's heat flow or helium that is so wildly discordant with our usual ideas that it requires an outrageous hypothesis to explain it. This is incorrect."

 

Cold fusion

What if we drill deep into mars and blow a few thermonuclearfusion bombs to heat it up?

It would take more than a few nuclear bombs to heat up a planet enough to notice!

 

Mars masses about 6 * 10^23 kg. It takes about 4000 J to heat 1 kg (of water, but, for estimating purposes, you can think of it as 1 kg of anything) 1° C. A ton of TNT (what engineers commonly use to measure the energy yield of nuclear weapons) is about 4 * 10^9 J.

 

There are something fewer than 100,000 nuclear bombs of all kinds – gravity dropped, missile warhead, etc. – on Earth. The largest nuclear bomb ever made had a yield of about 50,000,000 tons TNT. So, if every bomb was the largest every made, their total yield would be about 5 *10^21 J. In reality, the average yield of a nuke is closer to a couple of kilotons, about 1/10,000 the yield of the “Tsar bomb”.

 

If one could deliver all these bombs to Mars, and detonate them in a way that efficiently spread their heat through the whole planet, they would heat it about 0.01° C (assuming all 100,000 are “Tsar bombs”), or 0.000001° (assuming a realistic collection of bombs).

If it could it be used on moon....

At about 7 * 10^22 kg, the moon is about 1/10 the mass of Mars, so all the nukes in the world, efficiently detonated, would heat it by about 0.00001°.

 

Comparing realistic estimates of the energy available from nuclear weapons with the popular perception illustrates a huge gap between the two. Though awful in terms of their potential to destroy life, these weapons aren’t significant in their ability to effect planets.

 

 

Mars receives about 3^14 W of solar power, the equivalent of all the nukes on Earth being detonated over a 30 minute period. As an energy source, the Sun dominates the inner solar system.

So why isnt the core rapidly cooling?

It is cooling, but it takes a while and you can't blame it!

 

Volcanoes, geysers and thermal springs, continental drift and earthquakes, it just takes a while!

[Roadam]

Well I was not thinking to heat up entire planet. Only a little part of the core. It is probably still at temperature few hundreds under liquid state so 1 kiloton bomb would heat about 1.000t of rock for 1000K.

 

It is quetsion only what effect would liquid have on magnetic field. Mars is spinning as much as Earth so....
