It depends on what you use for material, geometry, how fast and how much you can compress the package and your neutron reflector.

The ultimate gauge of "am I there yet" is the neutron mean free path. When that starts ending inside your fissile mass you are in the ballpark.

Ways of achieving that are more mass (that's how you get that bare sphere number), more density, an efficient topology, and a better reflector. If your fissile puts out slower neutrons you have shorter mfps but may also capture instead of fiss.

Most of the work centers around more better explosives, and there are some amazingly good ones I won't go into detail on lest we have another incident, since this was more or less the discussion that initiated the 2004 holocaust.

A perfect neutron reflector will put every neutron emitted back into the mass, so every mass is critical, more or less. Other limits would come into play but you could probably get one as small as a golf ball.

Reactors don't go nearly as supercritical as a nuke, and therein lies the difference.

Antimatter is a hot topic, but not as a bomb.

When we start to produce antimatter in sufficient quantity(currently well beyond our ability)we will probobly do so off world so as to avoid any potential mishaps.

Hell of an expensive prospect for a bomb all the same, never mind the containment issues you would also have to contend with.

Personally i imagine if we do ever mange to produce the stuff in quantity it will be used for energy production or space propulsion purposes.

They can make antimatter now?



www.symmetrymagazine.org...

All of the antiprotons created at Fermilab’s Tevatron particle accelerator add up to only 15 nanograms. Those made at CERN amount to about 1 nanogram. At DESY in Germany, approximately 2 nanograms of positrons have been produced to date.

If all the antimatter ever made by humans were annihilated at once, the energy produced wouldn’t even be enough to boil a cup of tea.

The problem lies in the efficiency and cost of antimatter production and storage. Making 1 gram of antimatter would require approximately 25 million billion kilowatt-hours of energy and cost over a million billion dollars.




an old quote about new technology....



www.pcworld.com...

Foolish Tech Prediction 1
"I think there is a world market for maybe five computers."

Thomas Watson, president of IBM, 1943



And I still stand by there being a breakpoint were the amount of radioactive material / fusionable material in an atom bomb / thermal nuclear bomb becomes so small, the conventional explosives needed to trigger the radioactive reaction produces a bigger explosion that what the nuclear material/fusionable material can produce.

"They can make antimatter now?"

Very small amounts yes.

It would cost around $25 billion per gram.

That's rather an expensive overkill form of weapons system when a good old conventional nuke could do the same job.

If and when we make antimatter it wont be for bombs unless we are trying to destabilize a star.

Doesn't it take about 30 pounds of plutonium to fuel a chain reaction?


Yes, I'm not sure of the amount required, but the physical requirements of the amount of nuclear material needed to create fission seems that mini-nukes of this type are only a reality in science-fiction, not in actual science.

The idea of a nuclear bomb the size of a hand grenade or smaller is ridiculous.

And I say give it 50 to a hundred years.......

Especially for the desire to create a mega weapon without the fallout.

But atom bombs and thermal nuclear bombs are at there practical limits.

The fallout, and Any device over 100 megatons is wasted do to the simple fact any additional energy is just pushed into space.

Maybe DARPA has finally perfected Hafnium bombs.

With shielding, the size would be comparable to a grenade. Hafnium can absorb a massive amount of energy and the theory is that it can be triggered to release it all as a gamma ray blast.

I always thought the idea of a nuclear hand grenade was rather fascicle.

Never mind the material issues and other problems associated with the construction of such a weapon. You would need to have some arm on you to lob the thing further than the god darn blast radius for a start.

Nuclear isomer weapons would be interesting but no one's made one go yet.
