As seen in the Star Wars series, no. However, The Berkly institute has developed a contained plasma arc device that looks, sounds, and behaves much like a light saber. It is far from portable though, as it takes a massive amount of power to operate as well as equipment the size of an SUV, not a flashlight.
As a modern-day religious group, the Jedi do indeed exist. However, they are not the Jedi of the films. They adopt names like Jedi-ist and Jedi Realist, and their beliefs are based around the philosophies of the Star Wars films by George Lucas, with some modifications (it looks as though these are site-specific, in most cases).However, if you want lightsabers and laser guns, you're out of luck: these Jedi don't practice telekinesis or build super-technological devices, and they don't fly around in spaceships--so, as cool as it sounds, the Jedi of the films will remain there.
We wouldn't know because if space didn't exist earth wouldn't exist and if earth didn't exist we wouldn't exist! So there you go there is your answer.
Rainbows do exist, yes.
He does exist like God
Well, depending on the creator or master, the colors of a lightsaber tell others what type of fighting style you are. This isn't true all the time, but most of the time. Green: Shii-Cho Blue: Soresu Red or Green: Ataru Green: Djem So Any color, but 2 lightsabers: Jar'kai The unorthodox is using more than two sabers, but that really isn't common, only if the jedi or sith was an alien species that had more than two arms or if it was General Grievous. The color of your lightsaber could also tell about your emotions, as Yoda would say to his younglings.
Real lightsabers such as the ones from the popular movie series Star Wars do not exist. However there are toy plastic lightsabers or glow sticks that will light up.
no starwars lightsabers would be to and to heavy, but if you wanted to extend comedy then cartoon star wars will have squirrels with lightsabers
No
They first used steel swords, then experimented with what they called "Frozen Blaster" technology, but these early Lightsabers were bulky and required a cable attached to a power pack on the Jedi's belt. Further experimentation led to Lightsabers.
YEAH!
Force FX lightsabers are far from childrens toys. They are fairly expensive, and are for serious collectors.
