when an antimatter atom combines with a matter atom, the masses turn into two high-power gamma ray photons shooting out in opposite directions. that'd probably be able to.... boil water or something to produce energy in some boring way.

or you could just stare at it and melt.

weapons, you can make a huge bomb capable of destroying a small continent, or bullets that explode killing the target instantly.

A battery the size of your thumbnail that will power your car from california to new york without recharging.

Even sooner, there are plans to develop a form of cancer treatment that uses a particle accelerator to make a small amount of anti particles to fire at tumors.

When antimatter collides with normal matter, both the antimatter and matter destroy each other in a process called "annihilation". Basically, it will produce more energy mass-for-mass than nuclear sources. Or it could be used for a weapon that can melt everything.

Incidentally, in my novel I have an aging Charles Pellegrino trying to shoot down the engineers who try to fix his Valkyrie for it to decelerate into Earth orbit (Where fixing means saying 'fuck it' and cannibalizing the engines into a solar sail).

If you could come up with a way to reflect gamma-rays, you could use a matter-antimatter reaction to power an extremely high impulse rocket engine.

i just wrote a paper on this, i had to learn a lot about it in the process.

antimatter has the potential to create really efficient long term spacecraft propulsion, because it reacts instantly with regular matter, annihilating all matter and creating energy instead. it would be better than a sustained nuclear reaction, which would require constant energy input.

however! it costs about 65 billion $ to create a gram of antimatter today, so it's not so feasible at the moment. there is also the potential for terrible, terrible weapons, but again you would need far more than a gram to do significant damage.

make a anti-photon lazer as a supper weapon

Its good for weight/output ratio, so its a very pure fuel. It also explodes pretty well. But it would only be useful in the first if we could more easily make it in the first place, because right now it takes more energy to produce than it puts out, because we can only make extremely tiny amounts

conductors where the positive charge actually does the moving!

Also known as the "photon."

>right now it takes more energy to produce than it puts out

that will always be the case

Never heard that one before. Can anyone develop?

we could produce approximately 120 kilograms of antimatter and use it to COMPLETELY and UTTERLY erase OP's faggotry from this universe

Why isn't positronium stable?

>>2184341
my interests, etc.. etc...

>>2184334
not if we find some property of it that we don't currently know. Scotch tape makes x-rays in a vacuum, what if we find something stupid and similar that makes antimatter?

>>2184366
stfu... who the fuck is "we"? go clean your room.

>>2184366
Damn.

X-rays, graphene...what will Scotch Tape do next?

>>2184366
just looked it up, thats so awesum

that's a wicked comic

This comic is 100% accurate. Where is it from?

>>2184314

Don't forget that it's also clean. not like fission that leaves a lot of irradiated crap behind.

Fusion energy leaves ehm.. helium.

Saturday Morning Breakfast Cereal.

>mfw people think anti-matter could be used for weapons like in a certain dumbshit movie.

I lost faith in humanity so long ago I stopped caring.

>>2186571
What, you don't think antimatter would be effective in a weapon? Extremely high densities of energy, man. You get a huge yield, larger than any other weapon realistically could give for the size of its payload.

>>2186519
Annihilation will not be a useful source of power generation on Earth. We would need an external source of antimatter. Maybe humans will one day coax antimatter away from nebulae and other places.

>>2186519

Helium-5 could be used in superconductors or in cryogenics. It doesn't go to waste, like the stuff that takes thousands if not millions of years to become inert. You mad, nuclear fission?

>>2186582
Relativistic mass impaction would probably be considered more devastating.

>>2184316
When do you think you'll finish your novel? It sounds intriguing from what you've said about it.

>>2186610
How would things get to relativistic speeds? Also, do you know why many meteorites don't survive to become meteoroids?

>>2186611

Well, it was supposed to be long-term sci-fi, but I have expanded the story that takes place in this century so much that I might as well cut it to only this millennium and write the next ones in other books.

So, I'd say, before the middle of next year.

>>2186614
Some Project Daedalus shit could be used I guess.
As for the micrometeroids I can think of several reasons, but it might help if you yourself specify.

Surviving the cruising is hard, though. Charles Pellegrino and Jim Powell proposed using magnetically-guided droplets to double as a radiator and self-fixing impact shield, seriously though, at >90% of c, I doubt the droplet shield will serve as a radiator: Contact with the interstellar medium will heat it up.

For my novel these guys use 'photomagnetic' shields, that is: Ultraviolet lasers ionize matter and this wireframe cone of superconducting wire takes care of deflecting it, consider it an inverted Bussard Ramjet.

Project Daedalus is smalltime, Enzmann probes up of in this bitch.

antimatter bullets. Finally the coil gun has a use again.
