What would an explosion from an anti-matter bomb look like? Would there even be an 'explosion' as we know it? Say, for instance, a starship fires a huge antimatter warhead into a planet. What would the people on the ship see? Would they see an explosion or just the planet vanishing into nothingness? How far away would you have to be to stay safe?

Also, how would you go about making one without accidentally taking out an entire sector of the Galaxy?

All that depends how much antimatter you have. A gram of antimatter can only annihilate with a gram of matter.

I fear you have been corrupted by angels and demons. If so, read this: http://public.web.cern.ch/public/en/spotlight/SpotlightAandD-en.html

If antimatter and matter really react violenty. Then wouldn't it go boom touching the bomb casing?

But the resulting release of energy would be catastrophic.

E=mc², bro. Mind numbing amounts of pure energy would be released. Same thing happens in an atomic bomb. Matter is destroyed. (though not quite as thoroughly)

I always wondered how they keep antimatter stored.

Anyone want to explain?

I'm not debating that; it still depends on the amount of matter and anti-matter you have.

>The inefficiency of antimatter production is enormous: you get only a tenth of a billion (10^-10) of the invested energy back. If we could assemble all 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.

lots of energetic photons, so think heat and light

Fucking plebeians. Nuclear energy has nothing to do with annihilation. It's simply breaking nuclear bonds and releasing THAT energy. Annihilations produce almost exclusively, gamma rays. It would be an entirely different experience than nuclear. Think of the difference between c4 and a nuke. A similar difference would exist between annihilation and nuclear.

Anti-matter is impractical however you look at it.

At the moment, it has to be painstakingly created which costs far more energy than you would ever get back from it. The only way it could theoretically be a viable energy source is if you found a naturally occurring stockpile of it somewhere in the depths of space.

And even then it would have to be somewhere extremely far away so it would probably take more energy to get it, store it and then bring it back than you would get from it.

Oddly enough NASA found a cloud of anti hydrogen a while back.

this is assuming antimatter is harvestable and weaponizeable.

>> No.1513397

If antimatter/matter interaction results in annihilation and gamma rays, isn't is gamma rays that 'spontaneously' form into matter/antimatter pairs? so called pair production? Granted they immediately/almost immediately annihilate eachother, turning back into gamma rays, which of course in time can turn back into matter/antimatter pairs, which. .

What causes the energy of antimatter/matter reactions to change electric charge at such a rate as to be gamma rays? Why not slower or faster?

>> No.1513489

isn't Antimatter produced by Blackholes? it just sucks everything in till there's nothing left. Gravity, mass, light, you name it. nothing can escape it if you get pulled into it's gravitational feild, plus the more it eats the bigger it gets. until eventually it collapses in on it's self and disapears leaving a a big spot of dead space on the map of the universe.

>> No.1513496

how can something that violent ever become harvestable, let alone contained or weaponaisable.
