People walk in the desert, why do many people walk for a few days and find that they are actually go

When we watch TV series, we will encounter many people who get lost in the desert, except for the characters with the halo of the hero and heroine, the setting of ordinary people is to keep walking, but they can never get out, and then they all die because of lack of water or lack of food. In addition, we will hear about an expedition that got lost in the desert and did not make it out, and unfortunately died.

It may be that we think it is strange from God's point of view, because most people think that if you get lost in the desert, you can walk in the opposite direction when you came, and you can always get out without turning a corner. In fact, according to the actual situation, if you get lost in the desert, it is difficult for ordinary people to get out, although walking in a straight line sounds very simple, but basically no one can do it. So most of the people who lost their way in the desert were trapped alive inside.

First of all, if you want to use the compass to walk in a straight line, it is actually very risky. Because the climate in the desert still has a lot of changes, and even a wind and sand blow from time to time, sometimes it will affect the local magnetic field distribution, so the compass is very inaccurate. If you're unlucky, you may be walking in circles by following the compass.

So the danger is still very high.

It is also difficult to move forward according to the reference. If you're lucky, you might come across a plant or two. But in the vast desert, the number of plants is so small that it is difficult to get you out of the desert.

With the exception of plants, there is basically no reference for immobility. Because the shape of the sand dunes is similar, if you follow the sand dunes, it is easy to missee the reference halfway and deviate from the original route.

In addition, it is even more difficult to rely on the sun and moon to move forward, because the sun and moon are also constantly moving, although their movements follow a certain trajectory, but if you look at it from the ground, it is difficult to find your own direction. Over time, there will also be a relatively large deviation, and it is more likely to let yourself fall deeper and deeper.

Normally, when we walk, our two legs are at the behest of our brain, and our brain has to correct the direction according to the information obtained by our eyes, so we can go wherever we want. However, in the desert, the eyes cannot receive the reference information of the surrounding scenery, and the brain cannot effectively control the direction of walking, and there is a slight difference in the stride length of the left and right legs, which will form a step difference, which will cause the direction to be deflected when walking. If you go on like this, the line you walk is two concentric circles, so you will go around in circles.

Because the surroundings are exactly the same, it's easy to get lost.

It's like you're in the forest, it's disorienting.

Because it's hard to tell the way in the desert.

Because the desert is boundless, it is easy to affect people's sense of direction.

The desert is too vast, and there is nothing obvious to identify.

Because the surroundings are all similar.

It may be that following the compass is going in circles.

Because the desert affects people's sense of direction.

Because the desert is so big that there is no end in sight.
