Raygun

Rayguns are types of directed-energy weapon, so far fictional, as far as is known in generally available information sources. They are classical and very widespread in science fiction. Types of raygun have various names: raygun, ray gun, beam gun, blaster, laser gun, etc. They supply the general role of guns in the scenarios of many stories.

Why rayguns are not generally known to exist in the real world

There are these reasons:-

• For laser guns, see Directed-energy_weapon#Problems with lasers.
• For plasma rifles and similar, see Plasma rifle#Unlikely in the real world
• In many science fiction scenarios, the laws of physics and nature of matter and energy are different from in the real world, for example the fictional Minovsky Physics, which operate in the Gundam fictional scenario.
• Many of them need non-existent materials.
• With current and foreseeable technology the amount of power that they would need is beyond the capacity of any handheld device. Current real energy weapons are large and cumbersome, and real man-portable versions are barely powerful enough to be considered weapons.
