Rather than recap the wiki article on antimatter I'll just post the link : Antimatter - Wikipedia article

You can also try a Google search for it. :p

Ok, I've heard time and time again that any antimatter will annihilate itself when it comes into contact with matter.


My question is this: ¿How do you contain antimatter?

It's a known fact that we today can make extremely small amounts of antimatter. ¿

In Star Trek antimatter is contained and mixed with matter to make energy.

OK, in order to mix antimatter with matter, you must first HAVE antimatter..... ¿ok, next you need to mix it with MATTER.

So, in the meantime between when you mix the antimatter and the matter, how in the hell do you contain it (antimatter)? ¿ ¿

If you contain antimatter in a mechanism made of antimatter, it will not explode..right? ¿but uhhh....... ¿ ¿ ¿somewhere or another this 'antimatter' containment device HAS to come into contach with matter...or else the entire univers would have to be antimatter...


SOMEWHERE Antimatter meets matter...... I don't get it.. ¿

For instance, this day and age we make antimatter in tiny amounts.... but..... shouldn't the antimatter immeadiately explode once it comes into contact with air or whatever?

All i'll say is 'vacuums' and 'magnetic fields'.

its not the question with what to contain but how to make. I say giant station in Venus orbit collection solar power and using it to make antihydrogen,meh, too bad human fools on this planet dont care.

Quoting from wikipedia:
Recent data released by CERN states that when fully operational their facilities are capable of producing 107 antiprotons per second. Assuming an optimal conversion of antiprotons to antihydrogen, it would take two billion years to produce 1 gram of antihydrogen (approximately 6.02¿1023 atoms of antihydrogen.) Another limiting factor to antimatter production is storage. As stated above there is no known way to effectively store antihydrogen. The ATHENA project has managed to keep antihydrogen atoms from annihilation for tens of seconds ¿ just enough time to briefly study their behaviour.

Another thing:
If we could assemble all of the antimatter we've ever made at CERN and annihilate it with matter, we would have enough energy to light a single electric light bulb for a few minutes

I don't see how this matter antimatter stuff is gonna help us achieve humoungous quantities of energy. We can't even keep that #### light bulb running for more than a few minutes, let alne power starships capabale of traveling between stars. We are long way away from a real progress in this field, and my only regret is that i will will die before i see anything palpable !

If only i could live forever...

LOL Bytales, you think narrow! on earth low power facility like that wont make anything,you have to have real huge power source ... like the sun that why i think a space station with huge solar panels should produce it.

Even IF we would be able to make large quantities of anti matter, there is still the problem of storage in large quantities.

What you think 1 kg of anti matter is capable of when a magnetic field fails? I can assure you that it would be a HUGE explosion unlike we have ever seen.

And 1 kg is nothing if your talking about mass production. So any anti matter facility would have to be off world. Like mars or a space station for example.

Antimatter, regardless that its ANTI, still has an electrical charge, just like everything else in existence, thereby being able to be manipulated and controlled by electromagnetism....a basic, fundamental, elementary and easily reproduced force in the universe.

@ Solesius: Starships have their own portable Anti-matter generators on board.

First it must be cool down to an extreme low temperature / vibration velocity, then by a combination of powerful magnetic /electrical fields and laser one can suspend the particles in a container with a vacuum..

In the future is antimatter particle will be store in Quantum wells, which are structure made of semiconductor where powerful electrical fields that will be generated. Experiments using positron have been conducted with limited success and as the technology advances, more powerful quantum wells could store neutral anti hydrogen atoms.

Unlikely an anti-matter facility would most likely be HUGE. Not something you just put into a starship casually.

True but they could mine it! Nasa has researched filtering positron from the solar winds for use as fuel supply on space ship..

To be honest, I'm rather impressed with the "light bulb for a few minutes" output.  As you pointed out, CERN has produced an inconsequential amount of usable antimatter.  You try to get electricity from a chemical reaction with a billionth of a gram worth of reactants, you're not even going to be able to measure the trickle of electrons produced, let alone do anything with it.  Same for anything else we've got.

With today's tech, that's true enough.

But how do we know something that can produce antimatter won't be small enough to fit onboard a ship?

I personally figure that antimatter catalyzied fusion would be more pratical than antimatter reactors. You only use a small amount of antimatter to assist in the reaction. And you can use the onboard regular hydrogen fuel as a source for making antimatter.

The same way we've made antimatter so far in particle accelerators.

Here's a question for you.... ¿

The "thing" that is used to created antimatter never actually comes in contact with the antimatter....... right? ¿ (because if it did, it would explode... )

So how does something create something with never coming in contact with it???

by using powerful magnetic,electrical fields..
