問題詳情：
Neil Armstrong, the first man ever to set foot on the moon, is best remembered by his words “That’s one small step for (a) man, one giant leap for the mankind”. Once, in an interview with his son, he said it was difficult to watch a sci-fi movie with his dad, because Armstrong would keep complaining about how unrealistic their vision of space were.
In fact, even the Oscar-winning Gravity, described as “the most realistic space movie ever” by Forbes, is not 100 percent faithful to reality. Here is part of a former NASA astronaut – Garrett Reisman’s movie review.
On the whole, it’s a great movie. But the question that most people want me to answer is how realistic it was.
In general, sci-fi movies are usually far-fetched. So it’s amazing how many things Gravity gets right. The danger of space debris（殘骸）is very real. There are currently more than 600,000 pieces of debris larger than 1 cm orbiting Earth and they pose a great risk to spacecrafts. However, in the movie, astronauts can see the debris coming and quickly seek shelter. In reality, debris can travel at 20 times the speed of sound, which means that if you can see it, it’s already too late to hide.
Another huge error was – there was absolutely no reason for the male astronaut Matt Kowalski to sacrifice himself!! He lets go of the hand of his female partner, Ryan Stone, and drifts away into space. In reality, Kowalski wouldn’t have flown away when Stone let go of his hand. Instead, he would have just stayed floating in that spot.
In the movie, Stone travels from the Hubble Telescope to the International Space Station and then to the Chinese Space Station Tiangong, where she finds an escape vehicle to take her back to Earth. But this is actually the biggest error in the movie. The Hubble, the International Space Station and a Chinese space station are not neighbors. Getting from one to the other requires so much energy that not even space shuttles had enough fuel to do it. In addition, space stations travel in different orbits, and they travel quickly. And it would be physically impossible to get from one to the other.
There are other, more minor details that are just unrealistic. For example, Stone doesn’t wear a cooling garment（降温服）under her spacesuit to protect herself from the heat in space.
. . . Yes, I could go on and on about all the things Gravity got wrong. But who cares? All of these inaccuracies were done to help advance the plot or to add drama to the films. This is entertainment, not a documentary.
