The very short answer is that the acceleration from the ship's engines is likely to be quite small. Note that this is an ionic drive that accelerates continually rather than a rocket that expends all of its fuel in a g-force inducing blaze of glory. [On Computer Screen] Failing systems: Life support. Fusion reactor. Ionic Drive Assuming that the ship ...

We are hurtling through space at an insane speed at this moment (30 kilometers per second riding on the back of the earth); did you notice it? No, because you can't feel speed, you can only feel acceleration. "The wind in your face" makes you think you can feel speed, as do the bumps in the road but that's not the speed itself. Again, think of travelling ...

The ending of the film was left intentionally vague by the film's director, Morten Tyldum. In short, he's happy for you to imagine that they went on to have kids, but only if you want to. We had a longer ending with Andy Garcia walking out of the elevator. 'Why is he in one shot?' Because it was two scenes that we shot with him, but we find out that ...

There would be enough technology and expertise on Homestead II. The same question was asked on another SE site a few weeks ago, and the accepted answer there argues convincingly that there may have been people asleep aboard the Avalon with the knowledge and tech necessary to put someone into hibernation. Recall how at one point in the movie Jim tries to ...

The important thing to note here is that like all of the other passenger amenities on board the Avalon, the spacesuits and 'EVA experience' are little more than a fairground ride. Computer Voice: We hope you decide to join us again... for another thrilling experience! We already know from the attempts to break into the crew quarters that our futuristic ...

In the 'Passengers' universe Arcturus is only (approximately) 20 light years from Earth. We can be certain of the ship's flight time because the map room tells us Jim: Wait. How long ago did we leave Earth? Maproom computer: Approximately 30 years ago. and we can be certain of the ship's location because when Jim uses the (laser-based) Comms ...

The description of Earth appears in promotional material from the company which built the Avalon. It is obviously trying to appeal to dissatisfaction with life on Earth, so it implies Earth is too crowded and too expensive. The company believes these claims will motivate the colonists. We do not know whether they are true in some sort of absolute sense, and ...

Narrative magic. Writers rarely worry about numbers. The bigger question is How was he not cooked through He is moving through interstellar space at .5 c outside the ship. Interstellar space is not perfectly empty. There is a thin mist of atoms, mostly hydrogen. There's about 1 atom of hydrogen per cubic cm. While outside the hull then as long as he'...

No. The relative dilation experienced at half light speed would be around 14%. Even if we assume the ship is referring to their remaining journey time in Earth Standard Time (which, for the record it isn't, but let's say it is anyway for fun) that means that their remaining 88 years would be reduced to, at most, 74 years. Given that Aurora is in good ...

The very short answer is that, at least according to the original script, Homestead II is already well under way in terms of colonisation efforts. The earlier colonists have built thriving cities with an eclectic mixture of frontier and modern technology. VIDEO INSTRUCTOR: And none is more beautiful than Homestead II, the Jewel of the Occupied Worlds. ...

The dialogue indicates that the autodoc is designed for a single occupant Jim: Inside the autodoc, you can go back to sleep. Aurora: But there's only one autodoc No explanation is given why this would be the case (nor why they couldn't jerry-rig the autodoc to manage two hibernation sequences) but I think we can assume that Jim investigated the ...

There are potentially two option here; 1) The ship is not obsolete. It remains the acme. Your assumption here is that technology is still advancing and that when they return home, the ship will have been superseded by more advanced technology. The flipside of that is that it's certainly not beyond the realms of reality to imagine that this ship is already ...

I think you are missing time dilation. At 0.5c, time is moving 15% slower on the ship. https://en.wikibooks.org/wiki/A_Roller_Coaster_Ride_through_Relativity/Time_Dilation So it is possible to cover larger distances in less time (our view). Or distance is compressed from people on the ship's point of view. However the number don't line up so well. 32 ...

19 years for the message to reach Earth. 19 years for the response to reach the point Avalon was when the message was sent. 55-19-19 = 17 extra years to reach Avalon. In 55 years, Avalon travelled the same distance that light travels in 17. 17 / 55 = 30.91% BUT there's a catch. To be honest, this answer may not be correct since travelling at this speed ...

Assuming an immediate response, the lasered signals to and from the ship must traverse a total of 55 light years. Since that's 17 light years further than the signals would have to travel if the ship and the message target were stationary, the ship must have traveled 17 light years in the same time that light traveled 55. This gives a relative velocity of ...

Different processes on the ship have different levels of automation. OK, maybe all of them have some level of AI, but the basic orientation programs are meant to be the same for everyone. There's no point in programming them to compute the amount of time that's actually passed, since the pods are only programmed to open when the ship is a few months from ...

At the start of the movie, they are 30 years underway. From that position, the signal takes 19 years to reach Earth. That means, with Newtonian physics, they are 19 light years (ly) from Earth. Average speed = 19 ly / 30 years travel, so about 63% of light speed. For the return signal, arrival is 55 years later (movie is not clear if this is 55 years ...

I believe that another thing should be taken into account: in my opinion the ship is not flying at constant 0,5c velocity. During the movie we see that the ship's engine is constantly in operation, therefore I believe that we should assume the speed of 0,0c at the beginning of the journey (relative to Earth, I believe that we can forget about orbital ...
