So I was thinking today while having fried rice on my dining table: "I will annihilate you!"
Ever been so angry that the good-old simple "annihilate" doesn't express your feelings? Well, adding a bit of physics to annihilate someone certainly sounds kool, but later today I found out:
In physics, the word is used to denote the process that occurs when a subatomic particle collides with its respective antiparticle. Since energy and momentum must be conserved, the particles are not actually made into nothing, but rather into new particles. Antiparticles have exactly opposite additive quantum numbers from particles, so the sums of all quantum numbers of the original pair are zero. Hence, any set of particles may be produced whose total quantum numbers are also zero as long as conservation of energy and conservation of momentum are obeyed. When a particle and its antiparticle collide, their energy is converted into a force carrier particle, such as a gluon, W/Z force carrier particle, or a photon. These particles are afterwards transformed into other particles.
Or, if you didn't read through all that: Annihilation is "the process that occurs when a subatomic particle collides with its respective antiparticle."
Or, in laymen terms: You short-circuit atoms.
Now comes the questions of practicality. Just exactly how practical is it, to actually annihilate someone? That's the problem. The pre-requisites to doing this is huge, and you have the entire humanity, the stake-holders of your "anger issues", at risk of being vapourized.
So... to physically annihilate someone is actually pretty hard, and you'd need a few googolplex dollars worth of equipment to do so. When you say to someone "I will physically annihilate you!", you are actually saying:
"I will take a enormous amount of particle accelerators and binding equipment and use up more than all the power that humans have ever used to create an anti-matter version of you (which has around 99.9999....% chance of failure) and then I will launch the two versions of you towards each other in a vacuum."
So although it sounds awesomely kool, it's not exactly the most efficient or practical way of dealing with that guy (or girl) who replaced your whip-cream with tooth paste yesterday morning. Frankly, if you can call this a Design Problem, then this would be some horrible design.
With that said, the next time when someone gets angry at you and tells you that they will physically annihilate you, feel free to say back to them:
"I'd really like to see you try."
