From beginning to end, there are no alien spaces and creatures in the location and content of the film. The only thing that attracts people's minds to other planets is a falling meteorite, but even so, the film still shows no traces of possible alien life. Before watching the movie, I once saw a film critic say, "This may be a new way for alien creatures to invade the earth, but it is only to copy the life of the people on earth to achieve the purpose of aggression." What the film really shows is a disaster caused by a physical phenomenon, not a purposeful invasion of alien life. If conditions are ripe, this phenomenon will occur without this meteorite.

2. About the essence of flicker.

The core sci-fi setting in the film is this kind of shimmer, which is called flicker, plastic wrap, or the poisonous circle in the amazing survival. In short, this thing is the curse.

Before she died, the female physicist in the film said that her inference about low light was correct, and low light reflected all objects. I suddenly realized. Remember the beautiful photos of them in the jungle of area X?

Newton used the dispersion principle of prism to reveal the secret of rainbow. The beautiful rainbow we see is actually caused by the refraction of light. Is that clear now? The shimmer is actually a very thin prism, which refracts the sunlight outside, causing the rainbow color in the X area. Twilight is more than just refracting light. It refracts all objects. How does a prism refract all objects? Here is another concept: wave-particle duality.

Maybe some colleagues or sci-fi lovers have heard the story of constantly chauffeured De Broglie. Yes, de Broglie discovered matter waves. Usually we think that light is a wave and matter is composed of particles, but de Broglie tells us that waves and particles are interlinked, and matter is both a wave and a particle. This is wave-particle duality. Then light is a wave, and a prism can refract and reflect light. Our body (everything) is made up of particles, and particles are also waves. Can a prism refract and reflect particles?

3. speculation about x region

A meteorite fell into the lighthouse, forming the X zone and emitting a shimmer. I saw a brother who studied theoretical physics post a film review @LPP, which mentioned that the abnormal gravity in X area caused the clock in this area to slow down. I stayed in area X for a week, but it seems like four months outside. In my opinion, it is possible. According to the general theory of relativity, strong gravity will cause the clock effect and the corresponding magnetic field effect to be annihilated, but at the same time, strong gravity also means great influence on living things. If the gravity is really that strong, the grass will not grow at all, and it will lie on the ground directly, and people will not stand upright normally, and will be crushed into patties.

So besides the gravitational effect, what other effects cause the clock to slow down? I think there is some kind of medium inside the X region, which changes the nature of this region and slows down the speed of light (pay attention to the speed of light in vacuum)! You know, in the relativistic effect, reducing the speed of light can also slow down the clock. As for the truth, emmm, you should ask the original. I'm just offering an unlikely possibility.

4. creatures in area x

In the film, it is repeatedly emphasized that the DNA of creatures in the X area has undergone tremendous changes, plants have mutated, plants have grown on animals, and reptiles have appeared on soldiers (this paragraph was reconciled in the cinema because it was too bloody). Under normal circumstances, DNA in organisms is copied in strict accordance with procedures. When an error occurs, the immune system in the organism will remove the wrong cells to ensure the normal operation of the system. But some wrong cells will bypass the immune system and replicate themselves indefinitely. This is cancer. As can be seen from the film, most people who enter the X area get cancer because of the strong radiation in this area. It goes without saying.

However, due to radiation and refraction, some plants are cross-seeded. Crocodiles even have multiple rows of teeth (I immediately think of polyploidy). Bears that eat shepherds will make the same sound as shepherds, and plants will grow on people. This is a bit illusory. According to the film, the DNA of some organisms should be reflected by low light, completely implanted into the DNA of another organism, and expressed in another organism. Imagine, if our world grows something we eat, wouldn't it be a bit like the movie? This is beside the point.

There is another phenomenon in area X, that is, the perfect replica, which appeared three times in the film. The first time was two sika deer, the second time was Kane, and the third time was Lena. This perfect replica is even more amazing. In my guess, it is very likely that the creatures near the lighthouse will be perfectly copied. The lighthouse is located in the center of X area, where not only DNA will be reflected by low light, but also protein, inorganic salts, water and other substances in organisms will be reflected to form new copies.
