The Phony Physics of Star Wars Are a Blast

I am huge Star War fan. The first movie came (no, not episode 1) when I was young, so I grew up thinking about Falcon Millennium And Lightsabers. Maybe my interest in science – even if it is not exactly a scientific imagination. Oh, there A nice way to start the student’s battle, which says a lot: Is the stars war “science fiction” or is it “imagination space”?

Either way, you have to admit that there are things there Look Like science. I mean, at any time you deal with things in space, it is an opportunity to talk about science. This is exactly what I will do, because today is the day of the stars war. It may be the fourth with you!

What are the scientific things in Star Wars are not scientific? I will go to some of the most interesting ideas, but don’t mistake me. I use these mistakes as a way to talk about science, but I don’t think it needs to be repaired. The most realistic star war is likely to be boring. Read, you will see what I mean.

Sound

The opening scene in Star Wars A massive star shows a smaller rebellious ship. You hear the engines, and give you the impression of a strong bowl. Unfortunately, this is not possible.

Let’s think of a moment for a moment. Suppose you click on the coffee mug on the side with a spoon. You hear a gentle small blush. This is because the tap causes the cabinet to swing back and forth, which pushes the surrounding air and pressure. This compressed air and then pushing on the other near the air with expansion. The whole process produces a pressure wave, and this wave of pressure is what we call the sound.

Can you have a healthy wave without air? certainly. You don’t need air, but you need Something For the pressure wave to travel through. This may be solid or water or in fact anything that allows high pressure pressure on parts of lower pressure. Sound waves need a type of average to “wave”. In space there is nothing.

Well, this is not so completely TRUE. There are charged molecules such as protons and electrons that move across space – from solar wind or debris from explosive stars. In the solar energy system, there is also some dust. However, the density of this “gas” will be very small, you can barely measure it. Very low to move the sound.

So why do Moviemans makers put the sound there in a vacuum? Well, most of us were not in space, and when things collide silently, it seems wrong. The voice of the destroyer reminds us of the huge star with the large ocean ship that passes near something that we can attach.

How do you direct this thing?

One of the big ideas in physics is that the forces change the movement of an object. If you apply a fixed and continuous power to an object – and there is no counter -power like wind pull – the object will speed up and Complement To accelerate forever.

We call the second law of this Newton, and it works with multiple powers on an object by replacing it with a single force called clear power, as shown below. here M It is the vehicle block and A It is its acceleration.
