Why are alien spaceships round, and why?

I'm sure you've all seen a lot of science fiction movies. In film and television works, we often see aliens. They travel in flying saucers, land on Earth, and go on sneaky activities.

Not only are we interested in this mysterious creature, they fly flying saucers, but they also become a fixed image in our hearts. As we get older, we start to feel a little skeptical. Why is it that in the eyes of most science fiction ** and even some scientists, alien spacecraft fly round flying saucers, while our manned spacecraft and rockets are streamlined structures or planar structures of spacecraft structures.

This makes us wonder why alien spacecraft are so unique, or if something else is going on.

First, it is actually very easy to understandFirst we can see that some rockets and spacecraft do not make long voyages and are actually only flowing within the confines of the Earth. There is an atmosphere in the upper part of the Earth. However, if we want to fly out, we must have a streamlined top structure.

Otherwise, too much pressure can cause serious friction damage, so our ships are generally streamlined.

Second, but in the universe, spaceships don't have so many requirements. In the universe itself, it is a vacuum state. No matter which way you fly, there's basically no air to back you up, so you get very far away.

Whatever mindset you design, it doesn't make much of a difference. That's just because we're all people with common sense. Also, since the alien has reached the level of interstellar travel, he certainly won't really fly directly into space.

He usually wants interstellar travel, either to travel at the speed of light, or through wormholes. The conditions of the voyage, his spaceship structure is in a relatively static weak state in time and space, which is a matter of minutes and seconds, so he does not have to worry about whether the structure of the spaceship will be hindered.

Three, so the alien spacecraft does not need to be streamlinedIt can be built like a flying saucer because they don't need to have very strict requirements about the way it flies. In the face of science and technology, all structures can be controlled, but the UFO structure in the eyes of humans should still be the result of the popularity of science fiction writers back then, but it inadvertently expounded the possibility of alien technology, so the alien spacecraft is a circular structure similar to a flying saucer.

There are two reasons for this, on the one hand, because the UFO was originally conceived as round, and then people have the stereotype that this is the case, and on the other hand, the circle is indeed more material-efficient than other shapes.

Because of the arc, that is, the streamlined resistance is small, in order to satisfy human curiosity about aliens, people try their best to imagine that everything seems real.

Until now, no one has seen aliens at all, so it is not known whether the alien ship is round or not.

Everyone should have watched the American film and television blockbuster "Transformers", and in this sci-fi movie, it was originally a car, or a fighter jet, but they were actually a kind of metal alien, and it was conjured up.

However, according to the research carried out by scientists in the United States, the UFO work that has been provoked around the world, we all know that the speed of the space flying saucer is very fast, and there is a certain degree of disturbance ability. However, we basically don't have any understanding of what kind of thing she herself is in the face of a space flying saucer, according to common sense, aliens should leave the earth in some kind of driving thing, but how do we know that it may be an alien that can be transformed?

In addition, we human beings have not really found a complete space flying saucer so far, and it is very likely that it was before the aliens, and we can't just believe in the conclusion, but one day, we will definitely figure out the true nature of this work!

The universe and nature are unknown to people, and the mysteries are endless, and people must be in awe of nature. If you're interested in these contents, follow them.
