They have no idea how much energy it takes to escape the sun's orbit. We use hundred of tons of fuel to orbit one ton communication satellites.
If the earth's core were uranium and fissioned you wouldn't even get to Mars. The current output of the sun would not either.
It would be far simpler to move underground where it's warmer and use nuclear for energy.
The imdb reviews are 90% fake 10* reviews. That doesn't make sense for a movie with limited US release. Are they Chinese propaganda?
sharethis movie is ridiculous and just poor overall, watched it on Netflix and could not wait for it to end
The film was heinous in its stupidity.
It was at about a six year old level and totally stupid regarding science.
I mean even superhero movies will have some kind of mild fantasy science explanations for superpowers. You can buy them if you accept the basic premise that something beyond the everyday is happening.
This is about turning Earth into a spaceship with near future technology and going on a 2500 year journey through space. Meanwhile, it's still light out on Earth, it's not like 500 below zero, and so on.
It was crazy bad but I guess could have been better if it was more distant in the future and more exotic technology was used, like force fields, etc.
It's still light out because they're still in the solar system. And it is pretty cold, cold enough to freeze a person to death immediately.
shareI think this film is more fantasy than harry potter - yet pretending to be sci-fi.
Having said that - I wonder if some conclusions can be drawn from the film - I suspect that China sees itself as the savior of the humankind, hence the film and its premise. To be fair, China does have a legit space program in place (CNSA). It also has big goals in space exploration - though we haven't seen any results thus far. But this film.... was a joke through and through.
It was a global effort, not Chinese. That particular plan to bounce off Jupiter was proposed by the Israeli team. The 2 Chinese kids thought of it independently and their team carried it out.
The father was insubordinate and disobeyed the orders of the United Earth Government including the Chinese.
The thrusters alone weren't supposed to get earth out of sun's orbit. That's why they had to use Jupiter to slingshot earth out of the solar system.
And the thrusters were fueled by fusion, not fission, so it should output much more power.
At every turn they soiled the pants of science. I wasn't expecting pure science but I was expecting some level of intelligent sci-fi to help overlook the nonsense. I was able to enjoy "Space 1999" back in the day despite its foolishness. Perhaps I would have been more forgiving if I could have seen it with subtitles and not dubbing (I hate dubbing). This level of taking-liberties may as well have led to them killing a giant space beast and making a planet-sized fur coat out of it to drape around the Earth.
Even beyond the absurdities, most of the characters were severely unlikable. Only the dad and the female military captain were likable. I will give it a few points for looking very good most of the time. This movie sucked. 3/10
"They have no idea how much energy it takes to escape the sun's orbit. We use hundred of tons of fuel to orbit one ton communication satellites."
Not sure about this. It's all about constant acceleration. You'll need several years, and this is explained in the movie. We indeed use tons of fuel for satellites, but mainly for getting them to orbit (i.e. to escape Earth's gravity). It's different in the movie, it's all done on the ground, depicted at a larger scale by orders of magnitude.
"It would be far simpler to move underground where it's warmer and use nuclear for energy."
The problem was the sun, which was going to engulf the Earth. The only alternative was to leave the planet (which they did, as plan B).
If they were light out, it's because they were near the engines, which were facing the sun all the time. It's also explained the Earth's rotation was fully stopped. What doesn't make sense to me is that they use this to explain the freezing temperatures. It should be the opposite, if you are facing the sun all the time, temperature will rise (unless you get too far from the sun).
While this movie might seem illogical/stupid, it is no more than, I'd say the vast majority of scifi movies from Hollywood.
