This is explained in the novel 2010: Odyssey Two. Jupiter's mass hasn't changed. It follows that there's no need to reconfigure the solar system to accommodate it: Do you have any idea what happened?’ ‘Only that Jupiter’s turned into a sun.’ ‘I always thought it was much too small for that. Didn’t someone once call Jupiter “the sun that failed”?’ ‘...

The justification for this is given several times over in the books, twice in 2010 alone:And because, in all the Galaxy, they had found nothing more precious than Mind, they encouraged its dawning everywhere. They became farmers in the fields of stars; they sowed, and sometimes they reaped.And sometimes, dispassionately, they had to weed.Life on Jupiter very ...

I meant catastrophic in the sense that the orbits would be thrown into chaos. Everything would want to orbit both the sun and the new star No, they wouldn't. Planets orbit a star because the star is much bigger, not because it is a star. Replace our sun with 2^30 kg of caramel pudding and absolutely nothing will change (other than getting colder). Jupiter ...

It definitely is a reference to Alien. It is self-explanatory and I know that Arthur C. Clarke knew Sigourney Weaver somehow, or somebody related to her because in one of his books, he referred to her as talented young lady, or similar, while mentioning this movie. And he, of course, knew the whole plot was wildly implausible, because if anything came from ...

Rotation around the roll axis of a long thin object isn't stable; a mathematical explanation of why can be found in this Physics StackExchange question. Even if Discovery was initially tumbling on its roll axis the instability would cause conversion to end-over-end rotation over time.

Life on Jupiter is in fact mentioned in the novel that the "2010" movie is based on: Bowman's avatar visits both Europa and Jupiter, and finds primitive (not intelligent) life forms in both places. The Monolith's controllers let him know that they consider it very unlikely for the gaseous lifeforms on Jupiter to ever achieve intelligence, but see that ...

2001: A Space Odyssey was written concurrently with the development of the film. This is covered in the Development section of the Wikipedia article, for example: Early drafts included a short prologue containing interviews with scientists about extraterrestrial life, voice-over narration (a feature in all of Kubrick's previous films), a stronger emphasis ...

The mass of Jupiter remained the same; the black monoliths increased its density until it began fusing hydrogen. Since its mass did not change, the orbits of our solar system would not be affected.

In the book, the Discovery's centrifuge (carrousel) spins on the yaw (vertical) axis of the sphere. from chapter 17 of 2001: The equatorial region of the pressure sphere - the slice, as it were, from Capricorn to Cancer - enclosed a slowly rotating drum, thirty-five feet in diameter. As it made one revolution every ten seconds, this carrousel or ...

If you watch the 2001 clip more carefully, you can see that most of the time, the actors are walking with a very stilted step (also mentioned in comments). Either the floor, or their shoes, are magnetized, which would be more practical than velcro for an environment that isn't carpeted. Nearly every scene in the pod bay in 2001 has them walking the same way, ...

While it's common, especially in sci-fi and popular science, to call Jupiter a "failed star", it's rather a misleading description. Let's look at some stars... Brown Dwarfs The smallest objects science considers "stars" are brown dwarfs. These are objects that are not massive enough to fuse ordinary hydrogen in their cores, but can fuse ...

There is a brief (but inconclusive) discussion on this issue within the film's tie-in novel; 2010: Odyssey Two. ‘I’m sure you will, Vasili,’ Floyd agreed. ‘But there’s a more important question. Why did they do it?’ ‘A warning?’ ventured Katerina over the ship’s intercom. ‘Against what?’ ‘We’ll find that out later.’ The implication seems to be that ...

More than one version of the 2001 book were published. You are correct in that the first draft had the monolith in orbit around Saturn. However, during the development of the film, this was moved to Jupiter. It is said that the special effects of the time could not show a ring system to tha satisfaction of Stanley Kubrick. Another 2001 book was published ...

They have velcro on their shoes. ("The stewardess came walking up the narrow corridor to the right of the closely spaced seats. There was a slight buoyancy about her steps, and her feet came away from the floor reluctantly as if entangled in glue. She was keeping to the bright yellow band of Velcro carpeting that ran the full length of the floor - and of the ...

If the ship had a torque applied to it perpendicular to the axis of rotation, conservation of angular momentum would cause the centrifuge to start to precess, inducing an end-over-end flipping. Such a torque could happen from the air slowly leaking out through the airlock doors (HAL was not online to make corrections).

Of the four major moons, Europa was the only one with an abundance of liquid water (under the ice). So, the monolith was warning humanity to keep clear of Europa and allow this life to develop. The message also states "ALL THESE WORLDS ARE YOURS" before the proscription against interfering with Europa - meaning humanity is free to expand and inhabit the ...

Scientifically in order for Jupiter to become the smallest type of standard star star (red dwarf) you would need 79 more jupiters to condense together. However a red dwarf doesn't emit the same kind of energy as our sun, it is far more radioactive. Creating a star the size Jupiter is now that emits the same kind of light and heat as the sun does is ...
