Well actually the way lightsaber work is that they superheat has causing it to ionize. This is called plasma. The plasma is then held in a thin shaft by a magnetic field similar to the force, but in this case, made by technology. The plasma is between 20,000 and 40,000°C. This then means the blade is at least as hot as the surface of a star. But lightsabers come with a problem. If they’re this hot turning one on would be fatal to everyone close. First the handle would turn to plasma as well. Then the wielder would be instantly disintegrated. After that the heat wave would melt and disintegrate anything in the room. Then anything within a mile would be melted. Then within minutes anything within 10 miles would reach 3,000°C. Which is really really hot. Lightsabers may not seem hear based, but when you break down the science, they are.

I’ve got something to say to this. While the details are decent the handle is way too thick and short to be useful. And it looks like vader’s saber but yellow
