Weapons of the future
Although humankind is capable of doing great actions, at the same time it can do terrible actions! The worst thing that people are capable of, is war! For this we need weapons. So, every country in the world is spending a lot of money, every year, so it can make more powerful weapons. Today the most important weapon is an armed soldier, but in future this may change. Even today, US army is spending a lot of money in developing aircrafts and robots that are capable of replacing soldiers in many danger situations. The common situation where robots are necessary is deactivating bombs!
In the future we shall have different kinds of weapons as well! One of them can be a Meshworm. This is a small robot that can move using artificial muscles that mimic the way an earthworm moves. It can be used to set up the explosive or to spy enemy forces. It is very strong, so hitting it or stepping on it wouldn’t stop it!
Microwave Ray Gun will be used to inject a loud sound into human head! Microwaves will be injected through the skull, so protective earplugs are useless, directly to the inner ear. It will recognize these microwaves as loud sound and the enemy soldier will be disabled.
Maybe the worst weapon of tomorrow will be Space lasers! The idea is to use artificial satellite to fire a massive laser beam on any location on the planet. This weapon will eliminate the need for standard warfare, but it will have a devastating effect on the world!
