Confinement of antihydrogen
Here's a somewhat recent article on CERN researchers isolating antihydrogen particles. The energy crisis will be solved sooner or later! What do you all think regarding this breakthrough?

Btw, this reminds me of a creationist argument. "How do protons and neutrons stick together if neutrons have no charge and protons are positively charged?" (By gluons)

RE: Confinement of antihydrogen
I don't think antimatter will help in any way with the energy crisis directly. Making antimatter is currently very energy inefficient. There are no projects planned to efficiently produce antimatter. I believe if engineers worked on a more efficient production method it could become more practical but not for power generation. It's probably something that doesn't scale down. It needs to be done on a large scale or not at all.

A reliable source of antimatter would have immediate uses like killing tumors by delivering precisely targeted radiation bursts. It would mean cancer patients having orders of magnitude less (I believe in the thousands) radiation exposure for killing off a tumor. You could get treatment and be fine a few hours later without the hair loss.
Medical imaging like positron emission tomography will become cheap and widely available. Maybe the resolution will be improved since positrons are cheaper and easier to produce.
Edit: This is a misconception here. PET doesn't involve antimatter directly - it involves ingesting or getting an injection of a special short lived radioisotope that generates positrons as it decays. With abundant supplies of antimatter other medical imaging techniques would be possible that would allow higher resolution images with less radiation exposure.

Another use is for single stage to orbit launch vehicles. Injecting antimatter into the rocket exhaust would boost performance and efficiency. You could use less propellant, leaving more room for payload. This would be good for heavy lifters. Something that can lift 1000 tonnes in one launch. There would need to be some radiation shielding to protect living payloads, though that shouldn't be an issue.
Antimatter is relatively clean, and comparable to fusion.

I think its quite impressive that they managed to contain anti-hydrogen. That is no small feat - since I think they are talking about atomic anti-hydrogen with a positron meaning magnetic confinement will not work. Anti-protons and positrons by themselves have a charge.

RE: Confinement of antihydrogen
Well, currently the production of antimatter takes a lot of time and money to generate a sustainable amount. Maybe someday in the future where particle accelerators are commercialised Big Grin

If I'm not mistaken, radiation therapy does not induce hair loss but the drugs used in chemotherapy can induce hair loss. Usually, a combination of both can be used to treat cancer. Furthermore, the gamma rays produced by the annihilation between antimatter and matter is of high energies and it may cause harm to the other healthy tissues. In my opinion, I feel that modified viruses should be used to treat cancer. By altering the viral receptors such that they can recognise a tumour cell based on the altered structure of the cell, the virions can easily dispose of the proliferating cells. I agree with you for the PET one. Maybe if they can merge the various scanning techniques together to create a better image?

I really hope for a future where antimatter is used as energy, having back a clean, fresh environment like that in the past is wonderful. Regarding an antimatter future, no weapons please, that will destroy Earth.

Antimatter will not be used as a general source of energy. Fusion power is easier, will always be more efficient to produce than antimatter (unless we find some new laws of physics to exploit), and just as clean.

There are allot of possible approaches to cancer treatment. I'm hoping there is maybe an easy way to train the body to kill it by itself. There are some vaccines that have worked in the small animal models that effectively kill certain types of cancer.

You are right about the chemo drugs and hair loss though I thought the radiation treatment did that as well. Antimatter annihilation creates a tiny (atom sized) point source of hard xray/gamma radiation. This allows for extremely precise control over which parts of the body are exposed by shielding and reflecting light going in other directions. It would probably be hard to improve on that.

eg: Compare the sharpness of a shadow generated by a candle with the shadow generated from a large florescent light.

Antimatter weapons - not likely - and not efficient. Antimatter fizzles.. You would have to figure out a way to make it all go off at the same time otherwise you would get allot of heat generated in the local area but not a massive shockwave with a large blast radius comparable to a nuke.

And if antimatter weapons could replace nukes it would be a good thing (and I'm not saying they will).. because nukes are dirty and leave behind long lived isotopes.

We should just concentrate on herbal medicine, for every disease there is a natural cure, we just need to find it. Cannabis is the main plant to concentrate our forces.

And about anti-matter, I know it's super-cool to find it and to artificially single it out, but what is the use for anti-matter? This is all just the beginning, so let them explore more uses, who knows what they will come up with...

Seriously...Big Grin lol ease up on the 'herbal medicine'.

Antimatter might only be in the early stages but it has allot more uses and potential than herbal medicine will ever have.

If there was a magic herb that cured everything we would know about it by now. It's not like there is something in nature the billions in our world population haven't tried.
Why hasn't anyone found this magic cure all herb? It would make them rich and famous! and not in the 'Dr Green Thumb' way.

RE: Confinement of antihydrogen
You misunderstood me. I didn't mean one herb, I meant for every disease there is a different herb, or combination of herbs. And those were not my words, I heard that from a professor at Agronomy Institute, so he is suppose to know what he is talking about, it's his life work. Also I know about some other doctors of medicine who don't prescribe "normal" pills, but their own "home-made" herbal medicine, if there is a cure in herbal medicine. If not, then they use classic medicine. I mentioned Cannabis because it is known to be herb with the biggest potential in medicine of all herbs.

But back to the subject, I do not want to make this into something else, this is suppose to be about antimatter. I find that very interesting subject, but still don't know much about it, so I am interested in the usage of that new "technology"...

Sorry but it seems you have a rather bad understanding of diseases and herbal cures. Modern medicines are usually the active ingredient of many herds concentrated into a viable dose and as much as I love marijuana myself I don't let it disillusion me as a possible cure, for anything. Now most of us know that it can be used to ease pain and help people eat when sick like chemotherapy patients but as for curing anything I haven't seen any solid evidence of that yet outside what crazy hippies preach. If the hippies are right, then I'll never have lung cancer no matter how much I smoke!

RE: Confinement of antihydrogen
Sorry, Filox, but unless I see proof of any of these herbal studies working (yes I know marijuana does help with pain), then I won't believe in anything like St. John's wort or Acacia berries until there has been scientific studies done by impartial parties with results that can be duplicated.

I do believe that there are plants out there that cure disease, but I think that unscrupulous people claim that just plain old herbs cure everything from arthritis to cancer without any research/questionable research backing them. The sad thing is they con desperate people to use these "cures", forsaking real medical help. Hell, even some of these "Natural Cures" are actually dangerous for people.

Like I said, I support scientific research into plants that may have chemical structures that do cure disease, but I need to see the evidence, otherwise I'll just stick regular old medicine.
