    Antimatter Fuel
AI Thread Summary
Harnessing antimatter as a fuel for future space travel presents significant challenges, primarily due to the immense cost and energy required for its production. Currently, producing just one gram of antihydrogen costs around 62 trillion dollars, making it economically unfeasible for practical use. Additionally, the physical laws governing momentum conservation complicate the potential for effective propulsion using antimatter annihilation. While the concept is intriguing and could revolutionize space exploration, the technical and financial barriers remain substantial. Without breakthroughs in storage and cost reduction, antimatter fuel may not be a viable option for future space missions.

Will we be able to harness antimatter so precisely that we use it as fuel in the future? I mean this would mean a great deal in space travel! Thoughts?

Give us some more of your thoughts to provide some context for this double question:
If it takes a million times more energy to make the stuff than it can produce, wouldn't it be rather 'expensive' ?
When used as 'fuel' (probably in the form of annihilation) there's a few physical laws that resist 'harnessing' -- such as momentum conservation. How do you think we could bend that to obtain propulsion ?

My bad. I meant not as a matter of expence but as a matter of exploration of space.

I fully realize that this post will probably get dinged for being un-scientific, but can I just point out that's how a Romulan Warbird is powered, while the OP's idea is how the Enterprise is powered? I just think it's interesting to see the reflection of society's constructs against the actual theoretical physics.

OK, my inner nerd is back in the closet. Sorry again, I'll make him do pushups until he apologizes.

Currently, it is too hard to store meaningful quantities of antimatter to be used as fuel. I don't see that changing any time soon.
 
It might be a good fuel, but a very important factor is money. For 1 gram of anti hydrogen, it costs 62 TRILLION US dollars to make it, and this is only 1 GRAM. I don't think it's ever possible to actually get this kind of money, only for 1 gram! Other than that, the antimatter fusing with matter could also create an explosion. If this explosion SOMEHOW can be contained AND the money won't be that much, then I would think that this is a good idea!
