Likely it would be some sort of combination of mirrors, ceramics, and liquid cooling. It would be good enough to get very close to the sun for a SHORT amount of time, but that's it.

The whole premise of the movie is complete bullshit though. Launching fissile material into the sun, even in that quantity, would do absolutely nothing. The sun runs on fusion, not fission. Putting a window on the front of the ship that is heading into the sun is such a stupid idea. The guy on the other ship that would take sun baths would have died from heat and radiation in seconds/minutes.

There is a LOT more wrong with the movie, but I'll leave that to everyone else. I will admit that despite the poor acting, shallow characters, predictable plot line, and completely bullshit story, it was a pretty entertaining movie and was very pretty to watch. I am completely infatuated with imagery of the sun.

>> No.3425182

>>3425012

Well, it would make sense if the movie weren't altered.

Originally the screenplay called for some sort of strange ball disturbance within the sun that was disrupting the fusion process. One which allegedly can exist in the universe, but is currently being tested for at the LHC. The nuke was to dislodge that foreign object.

I think the director decided it would be too complicated to explain to the audience, so that bit of information was cut, but none of the rest of the plot was changed. Resulting in not only an implausible premise, but an outright nonsensical one.

I'll admit that the art direction was the best thing about the movie, but I'd still give everything else in it a solid B rating. It wasn't THAT bad. More specifically,
>predictable plot line
Yeah, I totally see how you would've predicted them running into an abandoned ship, having a horrendously scarred, religious zealot maniac survivor sneak on board and murdering the crew off one by one while having the movie turn into a slasher flick out of nowhere. You'd have to be blind to have not seen that coming.

You know, just because fuck you, here's a direct quote from I, Robot:

"All that had been done in the mid-twentieth century on "calculating machines" had been upset by Robertson and his positronic brain-paths. The miles of relays and photocells had given way to the spongy globe of plantinumiridium about the size of a human brain.

She learned to calculate the parameters necessary to fix the possible variables within the "positronic brain"; to construct "brains" on paper such that the responses to given stimuli could be accurately predicted.

In 2008, she obtained her Ph.D. and joined United States Robots as a "Robopsychologist," becoming the first great practitioner of a new science. Lawrence Robertson was still president of the corporation; Alfred Lanning had become director of research."

The scientific errors aren't that bad and are at least overcomable if you do a little thinking for yourself.

There were machines to analyze the mind. No real problem with that. But all the control was done without any mechanical aid. The Mule himself was born with the power to alter the minds of others. The psychologists of the Second Foundation had to learn it, and they could still only do it if they had eye contact, unlike the Mule.

I believe the parapsychological elements in Asimov's work were added at the encouragement (or possibly insistence) of John W. Campbell, Asimov's friend/editor/publisher, who was into that sort of thing.

I think a better example of an author who writes truly hard SF without sacrificing artistic merit is Kim Stanley Robinson.

Well despite /sci/'s bantering, the movie is scientifically accurate and the most accurate one in recent years (which isn't saying much anyway).

Aside from the follow:
- No clear way for the ship to have artificial gravity
- That scene where the guy floats off to space exposed by the vacuum: could happen, but we will most certainly not possess the skin tones when exposed to a vacuum
- You can reignite the sun when such a bomb, but you will need about a billion of them to pull it off.
- The sun was hit by a supposed "Q-Ball" which caused such a premature death, but our sun will never EVER be dense enough to absorb a Q-Ball.
- Zero gravity does not cause a body to move slowly as depicted in the movie

Also the supposed window and observatory deck in the ship was not a window (since it was on the side of the ship instead of the front), but a giant screen that displayed radio from the sun through various filters and exposures.

I don't remember him being able to control/read minds, just manipulate emotions to the extreme, which isn't really that paranormal, just look at cult leaders or famous people. Now imagine a person whose charm compared to a cult leader's is like cult leader's compared to average 4chan asspie (if I'm making sense here). Person like that would be pretty close to the Mule. For comparison, look at the difference between da Vinci (whatever you may think of him, but let's focus on his abilities) and your local wall mart employee (or a god damn farmer, if you wish to compare people in same ages).

Mirrors and liquid cooling, most likely. Mirrors would most likely only reflect a part of the spectrum, while the rest would be absorbed. No idea how the liquid cooling would work in space, except for the ejecting of the liquid, which would be impractical due to the amounts they'd had to have.
