Matrix wrote: "Neatorama.com listed 9 physics laws that are completely ignored in Hollywood movies or TV shows. Usually, Hollywood producers follow the laws of physics because they have no other choice. The problem is when people are deceived by stunts in the movies, it seems that they really forget how the real world works.
1. Car explosion
It is often seen in action movies that a car crash or gasoline leakage with a small spark will cause it to explode. The reality is that gasoline can only explode when mixed with 93% air. In general, if you encounter a car accident, don't panic, as panicking may lead to more harm.
2. Sound and light occur simultaneously
In movies, thunder doesn't immediately follow lightning (in reality, sound is slower). Actually, they happen at the same time, whether it's an explosion of explosives or a volcanic eruption, sound and light appear simultaneously.
3. The myth of radioactivity
Movies seem to make you believe that radioactivity is contagious and can make you glow in the dark. The reality is that unless your body is contaminated with radioactive particles, there won't be any signs of radioactivity. Radioactivity is not contagious; if a person is exposed to neutron radiation, they might have slight radioactivity. As for glowing, unless your clothes are made of phosphorus.
4. Shotguns and kung fu send people flying
Some Hong Kong action movies or The Matrix are indeed very entertaining. However, force and counter-force occur simultaneously. Technically speaking, if you see the target being kicked away (or blown away by a gun), the kicker should also fly in the opposite direction, unless they are leaning against a wall.
5. The legend of falling
In action movies, cars often fly over a gap (like a bridge). In reality, don't attempt such things, you will fall into the gap instead of flying over it. The law of physics tells us that gravitational acceleration will make you fall. During the 1989 San Francisco earthquake, a person driving on an elevated bridge tried this, and the result was predictable.
6. The science of sound
Sound does not remain constant. Have you heard of the Doppler effect? If you fall off a bridge and shout, the sound of a woman's voice will sound like a man's, and a man's voice will sound like Kissinger's (?).
7. The direction of bomb explosions
In war movies, bombs around the protagonist always seem to explode upwards because the director arranges underground explosions. In fact, the direction of the explosion is in all directions.
8. Sparks from bullets
Bullets shot from a gun do not produce sparks. Friction on hard metal surfaces can produce sparks, but lead bullets (copper bullets) are dense and soft, so friction won't produce sparks. Sparks are fictional movie special effects.
9. Sound propagation in space
Sound propagation requires a medium."
