- Chances We’ll See It: Medium
Lightsabers are insanely popular science fiction inventions notable for their time in the Star Wars Universe. Are they actually possible? Today, we can make stuff like them but not to the same effect. It’s easy to make a sword that can display a laser-like sword. However, it won’t often be a cutting laser. The reason it is so hard is that containing the light of the laser is difficult.
Once it goes out, something has to stop it from continuing. If that is present, it means the laser cannot be as strong as it is in Star Wars. They are capable of cutting through nearly anything. We do have something like them presently though. The U.S. Armed Forces were given something called the “Metal Vapor Torch,” which looks exactly like a lightsaber in 2012. Tons of other types of these things have been seen since.
