We all have heard about the destructive power of the atom bomb.

The bombs dropped on Hiroshima and Nagasaki were fission bombs. Those bombs generated energy by splitting the nuclei of Uranium 238.

The nuclear bombs in our arsenals today are fusion bombs. They generate their energy by fusing Deuterium nuclei (Deuterium is an isotope of Hydrogen) to form Helium. The difference in the mass of Deuterium nuclei and Helium is converted into pure energy.

The conversion of mass to energy obeys Einstein's famous equation E=mc**2. Where E is the energy released, m is the mass and c is the speed of light (300 million meters/second).

There is a catch though.... the bombs that we used at Nagasaki and Hiroshima are terribly inefficient. Only a small percentage of the mass of the Uranium or Deuterium is converted into energy. In fact much less than 2% of the mass of these devices is converted into energy.

However, in theory, it is possible to construct a bomb that would convert 100% of mass into energy, which would create a bigger bang for the buck (couldn't resist using that pun!). This device would rely on matter and antimatter. Matter/antimatter is power source for the starship Enterprise's engines.

When equal amounts of matter and antimatter combine, they annihilate each other and produce an equivalent amount of energy (according to Einstein's formula).

The destructive force of a matter/antimatter bomb would make the most potent of our present day nuclear bombs pale by comparison.

Instead of bombs measured in megatons (millions of tons of TNT) of explosive force, matter/antimatter weapons would be measured in gigatons (billions of tons of TNT).

All that would be needed to trigger the explosion would be to simply switch off a containment magnetic field that separates the matter from the antimatter.

So, why don't we have one of these suckers? The reason is simple.... antimatter is extremely difficult to create. In fact, supercolliders which have been in operation since the 1970s have managed to create less than a trillionth of a gram of antimatter....

So, antimatter weapons exist on paper only, for now....

BTW... if matter/antimatter energy generation ever became reality.... there would never be an energy shortage ever again......

a gram of matter combined with a gram of anti matter would create 1,800 Trillion joules....

enough energy to meet our entire country's current energy needs for many many years!
 
It could be a good energy source, but I can't even imagine how you could harness or transport antimatter.

The problem with antimatter is that if touches anything, and I mean ANYTHING, boom, explosion.

The basic line is that this is a long, long way off. I doubt anyone over 30ish will live to see it.

It is contained in a very strong magnetic field so that it can't touch anything. I believe that an antimatter particle will only be annihilated if it meets a like matter particle....

for instance an electron and a positron, i.e., an "anti-electron", will annihilate and two photons with the energy equivalent of the sum of the masses of the two particles will be produced.

I believe that no one alive today will see this technology. It may not exist until after our grand children's time, if ever. The problem is in the production of antimatter. Producing Antimatter is very costly and requires a tremendous amount of energy, too.

Yeah BUT, what happens when the poles flop? Ka-BOOM?I've heard this flop is in progress, when it may occur I don't know.

Sure, a magnetic field would hold the antimatter in place, but what about the oxygen, nitrogen, argon, etc. in the air?

it would be contained in a vacuum
 
But how are you going to create a vacuum, install an electromagnetic field, and then put the antimatter inside all that?
We can't create "pure" vacuums. Even space has a couple of H atoms every cubic foot. There are always a few particles left, and all antimatter needs is one microscopic spec and boom, the magnetic field is blown out, and with nothing holding the antimatter in place, you suddenly have a very large hole in the ground.

Then again, this is all extremely far off.

So was the atom bomb, hell they didn’t really know they could do that.
Polio vaccine.
Satellites.
Maned space flight.
The internet.

The “this is extremely far off” list is very, very long.:)

It is being done today. As I said in a previous post, antimatter has been created in current day supercolliders. I didn't mention that the antimatter is being stored, too. Antimatter is stored in what is known as a "magnetic bottle"

And you are correct, you cannot create a pure vacuum, but it's not for the reason you cite. The reason has to do with a concept called the Heisenberg Uncertainty Principle. That law states that the product of the uncertainty of a particle's momentum and the uncertainty of a particle's position cannot be known within a certain constant (called "H-Bar")... if you had a perfect vacuum, you then would have a situation that breaks that law. It's the same reason that you can't ever attain Absolute Zero, too.

O BS, stop it Karl, I AM AN Absolute Zero! So it can be done.:cry:

Speaking of absolute zero have I ever told you about about my two senators, Tweedle-Dumb and Tweedle-Dumber?

In fact, the guys who got the closest to absolute zero ever (within a couple millionths of a degree) ran into a problem. When they cooled their stuff the first time, it got really close to absolute zero, then it just vanished...*poof*...gone. They had to reset their equipment in such a way that would prevent absolute zero in order to prevent this.

There is a state of matter known as a "Bose-Einstein Condensate" which only exists for certain elements and only at temperatures within a few billionths of a degree above absolute zero...

In this state of matter, all the atoms lose their identities and become a single entity. Even the individual neutrons, protons vanish. It's as if the atoms all exist in the same space. Once the temperature is raised above this threshold, the atoms spring back into existence as individuals.

It's almost as if, when it became very, very cold, all the posters on USMB became one massive cloud spread out across the country, then when the temperature rose, we all regained our identities.


BTW ... a bit of trivia... the physicist Max Born was the grandfather of the singer Olivia Newton-John... no kidding...

Yeah, these researchers made this 'superatom.' I remember reading about it in the newspaper and seeing a documentary later, but at one point, they made their entire experiment vanish.
