20 myths we believe in thanks to cinema

We have bad news for you: velociraptors were tiny feathered dinosaurs, lemmings did not commit suicide, and before the advent of the Internet, Americans received scientific information from Hollywood. We do not always expect that everything will be shown as it is in the film, and we are often ready to restrain our distrust, but sometimes it is simply impossible not to notice how absolutely idiotic myths are imposed on us.

In fact, the blades of a helicopter propeller are quite fragile. They are filled with foam or a light substance called "honeycombs", since the purpose of the screw is to cut air, not concrete. When a helicopter crashes, the blades are the first thing that falls off and shatters into pieces.

In fact, in space, the laser beam should be invisible. It doesn't matter if such weapons actually exist in real life (and they don't exist). To be visible, laser beams need an environment similar to fog, smoke or dusty air. Our atmosphere, depending on the type of laser, may provide conditions for visibility, but space - never. In a vacuum, we have no chance of seeing a laser beam.

Sorry, gentlemen assassins: such silencers simply do not exist. Silencers reduce the volume of the shot, but do not completely drown it out.

Alas, this is not the case. A concealed-carry bulletproof vest does not protect against automatic fire. He can only save from a pistol bullet, which in itself is wonderful, even despite the broken ribs. A military bulletproof vest is much stronger, but it costs thousands of dollars and weighs more than 10 kilograms.

Nothing like that! Do not confuse space with a swimming pool. Gravity has no effect on the movement of the body in the horizontal plane. And in zero gravity, in the absence of an atmosphere, in fact, a person moves even a little faster than on earth. However, moving slowly is a wise decision, but only in order not to crash into the dashboard or other equipment and not to break something important on the ship.

If this is a real predator, he will never do that. Animals, both living and extinct, demonstrated a type 3 functional Holling reaction, or in other words, biological common sense. If you have a sumptuous dinner on the table in front of you, why knock over a plate on the floor to chase after a waiter who brought some kind of snack by?

Well, no, actually the solution is even more ingenious. Teams to detect and neutralize explosive devices, as a rule, do not cut the wires. Instead, they use a tool that works like a firearm. A semi-automatic carbine or, for example, a sniper rifle. This process is called "active destruction", and it rarely ends with the explosion of a mine.

Actually, it's hard to find a less suitable place for this than a cave. After all, there is no light, which means there is no natural plant food. There can only be those nutrients that somehow got outside, for example, the excrement of bats. It's hard to grow big and strong on such grub. On the contrary, as a rule, cave dwellers direct all their evolutionary abilities to the maximum conservation of energy.

There is nothing like this on any submarine. The fact is that it is terribly crowded there, and every square centimeter is used with maximum efficiency. Even in the most modern submarines, it is barely possible to stand up in the cabins of senior officers. So, the only luxury for the commander is that he sleeps in his cabin alone.

No way! Unless, if you mean a million seconds. For example, the Enterprise ship in the movie "Star Trek: Retribution" would take about 80 hours to reach the Earth's atmosphere. And if it were in a stable orbit, the ship would not lose altitude at all, since orbital rotation does not require thrust at all.

And again we are being deceived. Radiation has nothing to do with radiation in the visible spectrum. Perhaps this idea arose when radium was used to make the tips of the hands of a wristwatch glow in the dark. However, even in those days, this glow was provided by the addition of special chemicals. Radiation is absolutely invisible.

Unfortunately, nothing like this exists. Different drugs make people more talkative and less withdrawn (perhaps the best of them is alcohol), but no substance can make a person tell the truth. In real life, if interrogators inject an arrested person with a "truth serum", it is only in order to deceive him and make him think that he cannot lie now.

However, in fact, in space, the Sun is absolutely snow-white. It looks yellow due to the fact that the earth's atmosphere scatters some of the rays with a shorter wavelength. For the same reason, the sky looks blue. At sunset, the scattering is more intense, so the color of the Sun deviates even more from white and it looks almost red.

Sooner or later, it may fall, but not so fast. Planes tend to plan well, even if the engines no longer generate thrust. The plane, which failed at an altitude of 12 kilometers, will most likely fly about 160 kilometers before touching the ground. So the pilots have some opportunities to prepare for landing on land or on water.

Nothing like that. And why on earth? The actual operating stations are perfectly lit from 7:00 to 23:00, because it creates a more pleasant atmosphere for work and life. There is no reason to keep the staff in the dark, except to create an "underwater effect" for the audience. In this way, we are forced to believe that everything is actually happening at the bottom of the ocean.

Wait a minute, friends. How can all this happen in an airless space? In fact, an explosion in space does not look so spectacular at all: the object suddenly just disintegrates in space. And also, of course, you know what it takes for us to hear the sound. Air, of course. The cosmic explosion, if we had a chance to see it, would have occurred almost in complete silence.

In real life, there may be problems with this. The fact is that the hatches in the elevators are closed from the outside. They are designed so that rescuers can get inside and get passengers out. An elevator shaft is an extremely dangerous space for untrained civilians. If you find yourself in such a trap, going out through the upper hatch, even if it could be opened, is much more dangerous than staying inside and waiting for help.

Most likely, nothing will happen. The pipes leading to the bath are now made, as a rule, of PVC, so there is no simple way to make the bath conduct electric current. In addition, the fuse in the device itself or the automatic interrupter in the dashboard will turn off much earlier than the toaster kills its owner.

Well, there may be serious difficulties here. In fact, the ventilation duct system is filled with a huge number of obstacles in the form of pipes, wires and other things. So you can crawl on them only in the movies, and even then, provided that the person is very small and agile. In addition, this method of movement is accompanied by such a loud sound that it simply cannot be called secretive.

How should I put it, you see. gasoline does not have explosive properties. If you throw a burning match into a barrel of gasoline in cold weather, the flame will go out before the fuel ignites. Gas stations and tanks are pretty safe places if we talk about the explosion of liquid fuel. The risk can only come from its vapors.
