    Antimatter Years

SUMMARY

The discussion centers on the production of antimatter, specifically the assertion that even with a fivefold increase in output at Fermilab, it would still take 200,000 years to produce 1 milligram of antimatter. Participants suggest that establishing multiple laboratories worldwide could expedite production, but the financial and logistical challenges are significant, with estimates of $10 billion per lab. The conversation highlights the immense energy required for antimatter production and questions its practical utility given current technological constraints.

PREREQUISITES
  • Understanding of antimatter production processes
  • Familiarity with Fermilab and its research capabilities
  • Knowledge of energy conversion principles, particularly E=mc²
  • Basic economic principles related to large-scale scientific investments
NEXT STEPS
  • Research advancements in antimatter production technologies
  • Explore the economic feasibility of large-scale antimatter laboratories
  • Investigate alternative energy sources and their efficiencies compared to antimatter
  • Learn about the implications of antimatter in theoretical physics and potential applications
USEFUL FOR

Physicists, energy researchers, economists, and anyone interested in the future of antimatter production and its implications for energy generation.

Ok, I've just been reading this http://www.cem.msu.edu/~cem181fp/antimatter/antimatter.html and it says that even if Fermilabs increases its production of antimatter to 5 times its current output then it would still take another 200,000 years to get 1 miligram of that stuff...
I know this might sound simple but can't they build lots of labs arround the world where they all produce the same amount of antimatter as the one they have now? that would reduce the amount of time we would have to wait for that darn 1mg, right?

Well, that's with current technology. Remember in those 200,000 years, the world population of scientists wouldn't be exactly just wasting time. That number should fall in time.

Notice that Fermilab isn't a dedicated Antimatter factory, but a laboratory. If we should ever wish to go into full industrial production of the stuff, then we can produce it at far better efficiencies than currently. But for the moment, we don't quite need all that much antimatter.

Remember, a little antimatter goes a long long way.
E = mc^2
= 0.001 * 9 * 10^16
= 90000000000 kJ in 1 miligram

This is equivalent to the amount of energy given out in the complete combustion of 1.6 *10^6 kg of Methane.
 
Oh, and you need to double that because it's matter-antimatter annihliation, turning the reacted matter into energy too.
 
re anti matter

and it costs a lot

Certainly, let's build 200,000 labs. Er, wait, if they cost $10 billion apiece (if we use Philadelphia building contractors) that would require the entire next hundred years of the US's GDP.

I don't think anti-matter will ever be a useful thing since it requires such a vast amount of energy to make a quantumitessimal (if that's not a word, it should be) quantity of it.
