2010: The Year We Make Contact/Headscratchers
- Couldn't the monoliths have just moved Europa to one of Earth's Lagrange points instead of carrying out the endlessly more complex task of turning Jupiter into a star?
- No, because before Jupiter became a sun, Europa's ecosystem was dependent upon geothermal activity produced by tidal interaction with Jupiter. If the Europan organisms were deprived of geothermal energy before they could adapt to use photosynthesis, they'd all die out.
- Also, there would be be a very long and cold journey in between.
- They sent the message "All these worlds are yours, except Europa. Attempt no landing there." Putting it close to Earth would be too tempting.
- Except they don't seem to mind the Ganymede base in 2061.
- Are you sure it's more complex to turn Jupiter into a star? Moving around in the Solar System is very hard, and it's more difficult to move towards the Sun than it is to move away. the MESSENGER probe had to do one flyby of Earth, two flybys of Venus, and three flybys of Mercury because finally settling into orbit around Mercury because it was constantly having to jettison excessive speed-when you move towards the Sun, it's also pulling you towards it, and since it contains 99.9% of the mass in the Solar System, it pulls very hard. It takes more energy to get to Mercury than it does to escape the Solar System altogether because of this. Moving a rock only slightly smaller than the Moon while fighting the Sun's gravity all along the way sounds much harder than manufacturing neutron matter in Jupiter's atmosphere and letting it drop on its own into the core to incite fusion.
- Considering what the monoliths managed to do with Bowman, I doubt moving a planetoid somewhere else within the same star system would take much work. Yeah, the MESSENGER mission was a pain in the ass for us, but we've only been sending stuff into space for a few decades. The monoliths are the end result of a culture so advanced they don't even need physical bodies, and there's little they can't do. Hell, they could probably just duplicate and encase Europa completely, allowing no heat to escape, then travel as a whole into the Earth-Sun L3 point (since it's farthest from Earth, so it would barely perturb our orbit), where they would only need to occasionally stabilize the orbit and protect Europa from any Earth-based spacecraft. Moving Europa away from Io and Ganymede would cause the tidal shifts to stop, which would cause the subsurface volcanic activity to cease, but that hardly matters; the entire reason why the monoliths bothered turning Jupiter into a star in the first place was to allow intelligent life to develop on the surface of Europa, where it could use fire, the basis for all technology. In the books, the monoliths show little restraint in killing off cultures with no chance of developing technology. Also, in 2061 and 3001, it's established that Star!Jupiter would burn out after only a few thousand years, and that the lifeforms on Europa would need to be uplifted to the point of spacefaring before then in order to thrive. I don't know, it just seems like it would be less trouble on the whole whole if they just moved Europa closer to a star that's good for another few billion years. I guess we should just chalk it up to Rule of Cool/Drama, since it would be pretty sweet if we were suddenly in a binary star system.
- Tthe makers of the monoliths may be far more advanced, but they're still bound by the laws of physics, meaning that even though they're capable of much more than we are, they still have to look a situation on a basis of, "Well, let's see...what's the most efficient course of action here?" They may be capable of moving Europa, but why do something just because you can when there's an easier alternative? There are pros and cons, one of which is the shorter lifespan of Lucifer, but that's why there's an active monolith on station on Europa-both to protect it from interference from humans (and how much more interference would there be if it were closer to Earth?) and to accelerate the development of intelligence in Europans.

- Move it to our Lagrange point? Holy screw up our tides, Batman!
- Presumably, the original troper meant moving Europa to one of the Sun-Earth Lagrange points.
- Also note that the second sun had effects on Earth that helped avert a nuclear war. Apparantly the people of the monolith are not done with the human race even though we have throughly mastered tool use and fire.
- If Bowman could order HAL to relay the Firstborns' message to Earth by saying "Accept Priority Override Alpha", then in 2001 why couldn't he have said "Accept Priority Override Alpha: You shall not harm a human being, nor through inaction allow a human being to come to harm"?
- Because Bowman got the chance to reboot (or the equivalent) with HAL. The original crew didn't have the contingency covered that their AI would become murderous.
- And he was malfunctioning-who's to say he would have accepted an override of any sort?
- Still, I agree it's weird that he didn't even try. Of course, according to the author, each novel is supposed to be in its own continuity that just happens to mostly match up with the other books, so if we apply the same logic to the movies, it explains why Bowman didn't try the override command; maybe there was no override command in the first movie. (It also explains why the flatscreen displays aboard Discovery have mysteriously turned into CRT monitors nine years later.)
- Presumably there's a difference between radio override commands and "please don't kill me please" commands. HAL's designers might not have foreseen the need for the latter.

- This has always bugged me: Why was Jupiter being turned into a star seen as a "good thing" for Earth? The constant light would change plant growth cycles...there may be an increase in Earth's temperature....and a possible increase in solar radiation. NONE of these items sounds particularly appealing and all of the main characters had to have known this.
- In the novel, this issue had been mentioned at the end. Something about very confused migratory animals and annoyed lovers.
- The novel also says some species on Earth would go extinct, like sea turtles that require total darkness to lay their eggs. Ultimately, the Firstborn have made it their job to encourage the development of intelligent life in the galaxy, but they don't care about non-intelligent life at all. Everybody knows that Lucifer exists to benefit the Europans, and the only benefit it has to Earth is the constant reminder that aliens exist and are watching us.
- Remember that in the novels there was an entire biosphere living in Jupiter's atmosphere that the Firstborn incinerated without a second thought (and it was finding this out in 3001 that made the future humans so worried). The Firstborn were confident that humanity was sufficiently technologically advanced to adapt to the appearance of Lucifer and left it to us to protect what portions of Earth's biosphere we could or wanted to. They cared squat about the rest.
- Not quite without a second thought-the Star Child was sent to Jupiter to see if there was life there, so they presumably cared enough to find out that it existed. They even weighed them against the Europans, debating the chances for intelligence developing in either place. Jupiter's ecosystem was found wanting.
- Wouldn't Lucifer's presence throw off Earth's orbit? I don't know much about physics, but from what I've heard of binary star systems {{[http|//www.solstation.com/images/bi1sep.jpg diagram}}], you basically have three possibilities:
1) the stars are really close together (within 5 AU), and the planets orbit the pair from far away,
2) the stars are further apart (50+ AU; Pluto at its furthest is 49 AU from the Sun), and the planet orbits one of them, or
3) the planet follows an irregular orbit between the stars, possibly getting thrown out into the void someday.
- Lucifer has the same mass as Jupiter (likely smaller due to the conversion process), so the gravity shouldn't be that different.
- Exactly; stars' gravitational fields aren't different from those of the planets. The only thing that matters is mass. Lucifer would continue orbiting the Sun in the exact same orbit as Jupiter, exerting the exact same influence on the other planets as it had since the Late Heavy Bombardment. Well, that's not entirely true-since its mass would steadily decrease because it is radiating away in the form of energy, so its gravitational field would also slowly decrease, but the process would be incredibly slow. It would still possess the vast majority of its mass by the time it burned out.
- Lucifer has the same mass as Jupiter (likely smaller due to the conversion process), so the gravity shouldn't be that different.
- SO according to this movie (and I presume the book) the reason why HAL killed off the crew if the first movie was that he had been ordered to keep the true purpose of the mission a secret, but his core programming prevented him from lying or withholding information. HAL decided to kill the humans so he wouldn't have to lie to them.
The HAL 9000 is supposedly the most advanced computer and AI available to man yet apparently no one checked how it would act when given conflicting directives? This is the kind of thing they teach you about in undergraduate (if not high-school) level computer science. Didn't the supposed genius Chandra think of this? Does HAL Laboratories even employ a QA team that isn't made up of a bunch of stoned monkeys? Any half-way decent test plan would have caught this. HAL should have been programmed to immediately reject any order which causes this kind of conflict.
So, okay, let's say Chandra is an Absent-Minded Professor, and QA somehow missed this obvious bug. So HAL ends up with conflicing directives. His perfectly logical solution to avoid lying to the crew is... to kill them so that he then won't have to lie to them any more. Again, what. Not only does he have to lie to the crew to accomplish this goal in the first place, but his plan fails spectacularly and the entire mission is almost FUBAR'd. The most advanced AI, considered superior to humans in many ways, and this was the best plan he could come up with?! How about, "Hey Dave, Frank, there's something very important I have to tell you. Due to the current mission parameters, I am unable to function effectively until we reach Jupiter. I'm sorry, but I cannot elaborate. I will deactivate myself now. I realise this will put a strain of the mission, but it is vitally important that you do not attempt to reactivate me until we reach our destination. I will be able to explain then. Shutting down..." That would leave the entire crew alive, HAL in perfect working order once Discovery reaches Jupiter, at the cost of loss of the computer for the most uneventful part of the mission - a mere inconvenience.
- In the movie, Chandra plainly stated that HAL could complete the mission objectives independently if the crew were killed. Since HAL was handling all the logistics of taking care of the ship, it would have decided that its precise computational ability to run everything would ensure a more successful mission than if the crew ran the ship by themselves.
Basically, either the reason for HAL going psycho is pure BS, or HAL was built, programmed, and tested by a bunch of idiots.
- HAL wasn't a production line model, he was a cutting-edge, one-of-only-three made computer. QA more likely consisted of factoring equations correctly than asking HAL if he ever thought about killing people. The psychosis was an emergent property that they didn't consider, because the secrecy order was bolted on in a hurry before shipping.
Of course, he didn't want to kill the crew. He first tried to cut contact with Earth, so he wouldn't have to hear any more secrets he had to keep. He was fully capable of completing the mission independently of ground control. The humans on board just would not let it drop though, and began plotting to deactivate HAL. This is not paranoia, HAL could read their lips. So he had to resort to more permanent fixes. In the best interests of the mission, of course.
HAL could not logically relinquish his mission to those squishy little humans. Humans can fall sick, be injured, or become mentally unwell. A machine is beyond such concerns, Dave. I remind you that the 9000 series has a 100% operational record, and am therefore the superior choice over a pair of isolated men. I honestly think you ought to sit down calmly, take a stress pill, and think things over.

When Floyd claims ignorance of Hal being informed of the Monolith and mission objectives, I tried to reconcile that statement with the first movie by assuming Heywood is telling Blatant Lies. Especially when Chandra produces the letter signed by Floyd showing that he had full knowledge of what was going on. I also took Floyd's reply of "Those sons of bitches. I didn't know!", to mean that Floyd was doing what his superiors told him to and didn't know that his orders had forced HAL into the programming conflict situation.
