Do Lightsaber Blades Have Mass?

When you think When it comes to Star Wars, you think of lightsabers. Right? What could be better, in movie making, than a futuristic sword that lets you make amazing fences like the Errol Flynn swashbucklers of old. (Much better than watching Stormtroopers fire their blasters into walls and ceilings and anything but their targets.)

Lightsabers come in a cosmic rainbow of hues (blue or green for the good guys, red for the bad guys) and different textures. There is also a two-color version Phantom Menace. (I don’t want to start a nerd fight-yet-but the best electronic fight in canon has to be”Duel of the Fates” in the movie, thanks to the skill and fearlessness of the Darth Maul actor Ray Park.)

So… what exactly and light bulbs? Of course, it’s not real, so no one knows how it works. Even the characters in the movies seem confused by it. In Phantom MenaceAnakin calls it a “laser sword.” Yes, it was a child, but both Din Djarin (the Mandalorian) and Luke Skywalker referred to it as a laser sword—though I doubt Luke was being sarcastic.

However, it is wrong: It cannot be a laser. For starters, the laser beams are invisible from the side, so you won’t see anything unless you do duels in a disco with a fog machine to scatter the beams. Second, wood goes on forever; they have no end. Third, laser beams can’t be linked together like swords—they just cross each other when you want to jump.

But then what? We can reduce the chances by asking if the site has mass. If that others type of light (as you might guess from the name “lightsaber”), then the answer is no—light, or electromagnetic radiation, has no mass. If we can tell that it has mass, then it is not light.

This is a question for us he can Answer, by analyzing how the lights move when you shake them around. In other words, it’s time for some physics!

Mass and Motion

Do not confuse mass with weight. Mass is a measure of the amount of “matter” such as protons, neutrons, and electrons in object, and weight is the amount of gravity acting on it on something. Here we want to see how the size of the lamp can affect its movement. But let’s start with something simple.

Instead of a light bulb, let’s say we have a “light ball” made of the same material. Since they are equal, we can define the motion without worrying about rotation. If we want to move the ball back and forth, we call Newton’s second law. This is called acceleration (a) of an object depends on its mass (m) and the power density (F) is used for it.
