"Interstellar crossing" in the physical interpretation, after reading forced to improve a lot of ~

America's "brain-burning blockbuster", "Star Trek" is aggressively the plot of the movie is about an endangered planet, and desperate humans send their last crew to try to find a new home for life by passing through a tunnel in time and space ...

But in the appreciation of the wonderful science fiction lens, a series of professional nouns but let a lot of the viewer "kneeling", more people call "not good study even the film can not understand." What do these "silly points" mean? Is the scene described in the movie possible? Reporter interviewed in the other side of the ocean in Jiangsu Province Astronomical Society secretary General, astrophysicist Li Yu, he said after watching the film, this is only a film, the content of the wormhole, high dimensional space, etc., are physical theory, whether there is really exist, the current human has not been able to prove.

Scientific point of praise

the most accurate black hole model ever seen, people can't "Come back Alive"

As the most dark and dense substance in the universe, black holes ignite many people's imaginations and provide wonderful materials and settings for many science fiction and movies. In this movie, a black hole is actually the most accurate black hole model ever created. This is 30 people, thousands of computers in a year's time, creating a history of the black hole the most accurate model of the face.

The black hole simply says, is the space one gravity is very strong, strong to the light can not escape a point. From the perspective of general relativity, a black hole is a space-time "singularity", and you can think that time and space in a black hole solidified. But it's a very complex thing to get into a black hole, because the gravitational pull of a black hole is so strong that the object is near it, sucked into a huge disk that rotates around the black hole, called an accretion disk. We all know that matter can be converted into energy, and the highest energy conversion rate in the world is the accretion disk near the black hole. Its conversion mode is the secondary school has learned the release of gravitational potential energy. With 0.1 grams of water as an example, the energy released into a black hole can kill 1.8 billion people. So the accretion disk is millions of high temperature plasma, releasing a lot of high-energy rays, such as X-ray, gamma rays. The first black hole astronomers discovered-Cygnus X-1 is a strong X-ray source, a job that won the Nobel Prize for 2002 years.

If there is a black hole, then can humans survive in it? Not。 The gravitational field of a black hole is very sharp and rapidly changing. Any object that falls into a black hole will be stretched by the great gravitational pull of the black hole, like pasta, and torn into a thin piece of matter. In other words, no matter or anyone can survive a black hole, communication is an impossibility. "said the astronomy expert.

Earlier this year, however, the famous cosmologists, Stephen Hawking, had pointed out in the classical theory that black holes do not exist, he admits that his initial understanding of the horizon is flawed, and proposes a new "gray hole" theory that the matter and energy will be released into the universe after being trapped by a black hole for some time. Because all of its knowledge is only theoretical, so what is inside the black hole, there is no saying in physics.

heaven for an hour, the ground has been n years! Physicists have proven "reverse growth" possible!

Such a plot in the film caused a wide "spit trough": the eternal Number first to Damille, on the miller every hour is equal to Earth seven years. Three of Cooper, Amelia and Doyle landed on the airship, while another scientist, Romney, stayed on the wing. Cooper and other people found that Miller only a sea and due to the addition of Messiah gravitational traction and often appear giant sea 潚. Amelia because want to get back recorders caused Doyle failed to catch and return to the airship and was swallowed by the tsunami, the airship because of the water and need to spend about an hour to take off, after the return of the eternal number found for Romney has spent more than 23 years, he even white beard. At the end of the film, when Cooper, who had left Earth for 91 years, was technically a 124-year-old Cooper, he left the appearance. And his daughter is oldest old. Why is there an hour in the sky, the ground has been n years? "To go over there is simply natural reverse growth." "The fans around me said with a smile.

Experts say the phenomenon is in fact consistent with Einstein's theory. According to Einstein's theory, when people move near the speed of light, time slows down. On Earth, scientists have proved this theory through experiments. This phenomenon has been validated. According to Einstein's special theory of relativity, objects moving at different speeds experience differences in time. For example, astronauts on the moon move faster than anyone on earth, and they age slightly slower than anyone on earth, but have not yet reached an obvious level. Unless, your speed is near the speed of light, but from this point it is difficult to achieve. When objects move rapidly in the universe, we can see this phenomenon.

"Fantastic" high dimensional space, the imagination of time warp and space-time tunnel to the extreme

At the climax of the movie, Cooper fell into a dreamy, high-dimensional space. It's like opening a high-energy mode, and this wonderful piece of content also allows all the viewer to "bow down" to the imagination of the film.

According to Li Yu, this part of the content, has been so many years of our time and space tunnel, space-time distorted visual image of the incisively and vividly. The description of the story itself is purely science fiction, which transmits information from one space-time to another. And the hero's own time and space, according to the play is described as the fifth dimension, and our space-time structure is four-dimensional. In fact, the film is very complex in the description of black holes and this hyper-space-time. The film used a word tesseract, the Chinese translation of the four-dimensional super square. From the geometrical point of view, it is the three-dimensional world of the cube in the four-dimensional world performance, like a cube relative to the square. When the hero falls into this space-time structure, he looks at his past wantonly, trying to find a way to communicate with the past.

Theory "nit-picking"

are fast film "play Bad", in fact, the wormhole has not yet been confirmed

In the film, the hero, former NASA astronaut Cooper and his teammates, use a wormhole near Saturn's orbit to enter another planetary system. The wormhole bends the space so that the extra distance travel can be done in an instant.

While entering the wormhole, the colorful light around makes this sound "sci-fi product", more like a colorful disco light. "Is there really a wormhole?" At the time of the movie, a female audience around the reporter was puzzled.

Speaking of "Wormhole", I believe many female readers are not unfamiliar. Before aggressively's Korean TV series "From the Stars of You", handsome to have no friends of the professor is to use it, to and fro to earth and thousands of Chung-yi dating. "Wormhole" is a space-time tube connecting the distant regions of the universe. Dark matter sustains the opening of the wormhole outlet.

Wormholes can connect parallel universes to baby universes and provide the possibility of time travel. The wormhole may also be a space-time tunnel connecting black holes and white, so it is also called "Ash path". If, for example, a piece of paper can be viewed as the usual space, a point from one end of the note to the other will need to span a distance; however, if we connect the two ends together, then the distance between the two points is very short. Wormholes are similar to these "connected" ends.

The wormhole was actually an early-born concept that was found in the solution of Einstein's field equation in 1916 and was formally presented by US physicist Wheeler in the 1950s. The sci-fi significance of wormholes is enormous, because if we have a wormhole, then interstellar exploration will be fruitful. Unfortunately, from the astronomical point of view, there is no evidence to suggest the existence of wormholes so far.

chemistry pushes "not enough", ions push too slow, space station fuel how to solve the

However, Li Yu also believes that there are a number of small areas of the film can be discussed, such as the space station to provide gravity, should be how fast? such as remote space flight, how to solve the space station's fuel? What's the push? If chemically propelled, it would be obvious that 10 space stations would not be enough, and if the ion thrusters were used, the speed would be too slow. As "communication" in different space-time, how does the table "move"? "But it is undeniable that the combination of science fiction and human ingenuity, with complex physics concepts, completes the overlapping and inversion of time, and is a masterpiece in making this film across so many fields." ”

Hide Plot

"Facing the Sun" flying away from the planet, implying a "double star system"

In addition, the film has a lot of "brain hole open" plot. For example, they entered a planet full of water, in order to escape the mountains of the waves, they are facing the "sun" flying away from the planet. "This is a very interesting part of astronomy. Because it implies that the life system they are searching for is made up of binary systems. One of them has evolved into a black hole and the other is a dwarf star. The gravitational pull of a binary system is much larger than the gravitational pull of our solar system, which makes it a huge wave. "Li Yu said.
