This film imax is still very good...Science fiction has been written for decades on the theme of space disaster survival. Finally, someone has filmed a movie, which is quite impressive.
(The classic short story of space disaster in my mind is Clark’s "The Summer of Icarus", http://www.guokr.com/post/530215/ , you can compare the themes of the two, they are actually the same.)
— ———————— I’m the dividing line of rework—————————— I’ve
patronized Tucao. Since I have occupied a film critic position, I must at least comment on it symbolically...
Uh,
it’s extremely useful. High technology with a sense of substitution and impact has truly restored a classic theme of science fiction literature.
Therefore, technical control will see tears streaming down his face. Science fiction control will also burst into tears.
But others can't guarantee it. Its story is simple and plain, and its feelings are also simple and plain. To be impressed is to impress, and to not impress is to not impress. This is nothing
wrong ... As for the following slot problems, I am not sure if a person will be indifferent after watching Tucao first and then watching a movie, because I haven't had a second brush. ……Anyway, when I watch a movie, it is very high, and the disbelief of the slot is basically suspended.

But I still have to vomit when I vomit...
vulture.com published an article http://www .vulture.com/2013/10/astronaut-fact-checks-gravity.html , Chinese translation http://www.guokr.com/post/518596/, Interviewed astronaut Scott Parazynski, he said most of the slots. The arrangement is as follows:
Spacesuit
·Space is not quiet, and there is a soft buzzing sound when the spacesuit is working. If it's really silent, that would be a big problem...
·Realistic jetpacks are far from being so good, and the flying speed is very slow.
·Insulation clothes and paper diapers should be worn under the spacesuit...Of course, this is not as good as underwear...
Spacewalking:
·Most of the walks out of the cabin must be tied to a cable, and free flight without a cable is available, but it is extremely rare .
·If you really want to break away from the cable, you have to consider the track problem. After all, they are not in gravity-free space, but are orbiting the earth at high speed, and they cannot fly wherever they advance.
·The fire extinguisher jet propulsion is a classic stem (Wall-E is not an original), but it is actually not easy to use, because it is difficult to ensure that the center of gravity and direction are in the same line, and it is easy to turn.
·The time to get out of the cabin is precious, everyone has work to do, and the heroine will not work alone and the other two will play...
·The well-trained astronauts are very elegant in space walks, and they won’t rush to and fro. Of course you can say that the heroine is a novice, and the heroine is dragged down by her, but... see below.
Astronaut: In
reality, novices like heroines should be called "payload specialists". As the name suggests, she is a payload. Possess certain special professional skills and will return to heaven once, but such people will not take a space walk, nor will they learn to land a spacecraft. It's just passengers. Spacewalking requires several years of professional training and needs to be familiar with every detail of the spacesuit. Six months of training is not enough.
·Astronauts are really prone to dizziness when they first go into space, but they will not arrange to walk outside the cabin a few days ago. I usually feel dizzy when I start walking. It would be dangerous to vomit in a space suit.
· Crying in space, tears will stick to the eye sockets, and will not fly out and turn into water balls...unless you take the initiative to shake them.
space station:
· Hubble, the International Space Station, and Tiangong are all on different orbits, each flying at high speed, it is actually impossible to fly from one place to another.
· Tiangong will not lose altitude casually... Even if it is hit by a large amount of debris, it will take months or even longer to descend from its altitude (about 350 kilometers) to the upper edge of the atmosphere (about 80 kilometers) time. They are not airplanes, they are not parked in the air by lift.
Orbital flight:
·The threat of space junk is great, but now the chain reaction kills most of the satellites is really unlikely...Although it may happen in the future (see Kessel Syndrome)
·They are in orbit, not statically hung in the air, Therefore, the scene where the two people hang on the cable of the International Space Station, since they are relatively still, even if they let go, they will continue to advance along the orbit, and will not float away so quickly. In fact, the male protagonist should hardly produce any tension, and he can go back with a slight pull back.
——————————————————————
Then I will add a few more slots:
· Space junk flies extremely fast. Since it is so fast, it is impossible to stand on the same orbit as a slow space station. Even if the first time I was smashed, it is impossible for the two to return to the same place at the same time the second time.
·The orbit has not been calculated at all. A single ignition can change the Soyuz to a place where it can meet the sky. This luck can no longer be described (if you don’t believe it, you can play the Kerbal space program and feel it yourself... ). And there is no deceleration. Flying out of the Soyuz should carry the speed component of the Soyuz. This will still pass by the Tiangong...
· The movie says that the speed of space junk is 50,000 miles per hour. If this It is the orbital speed, which is three times that of the International Space Station. This speed (approximately 22 kilometers per second) will definitely hit the naked eye before it can be seen. Well, in fact, this speed has already exceeded the speed of the Second Universe, and it’s time to leave the earth... if It is relative speed, so even if the two move towards each other, they have to leave the earth.
·The circling time of the fragments calculated by the male protagonist in the movie is 90 minutes. I don't know how they count it... In fact, 93 minutes is the speed of the International Space Station itself slowly orbiting the earth, and the circular orbit of high-speed debris cannot be this time. I'm not sure if the high-speed debris can find a 90-minute elliptical orbit... But even if it can be found, it can't be calculated by mental arithmetic.
