TL;DR: Because the space around Io is full of large amounts of ionized sulfur produced by Io's many volcanoes. There are an absurd number of volcanoes on Io, and they spew out an enormous amount of sulfur. The low gravity and thin atmosphere allows the ejecta to escape Io's atmosphere and reach space. As a result, Io's orbital path is like a donut-shaped ...

Yes, it is absoluely a real Unix system, it was a Silicon Graphics workstation (using IRIX, the SGI System V based Unix) running a three dimensional file system browser. Silicon Graphics were early developers of hardware acceleration for 3D graphics, so it makes complete sense that even in 1993 they had Unix workstations capable of a 3D file system viewer. ...

Because they fail test screenings. The general movie audience does not respond well to realistic depictions of explosions or cannons at a distance. From the other SE, a partial excerpt of a great answer (that you should upvote as well): Most film is art, not life/reality. Sound designers have to match the visual art on screen with the sonic art of their ...

Because of powdered milk's resemblance to cocaine and other drugs, powdered milk is sometimes used in film-making as a non-toxic prop that may be inhaled. Other methods listed on nypost.com are - “It’s usually cornstarch, but you have to put a bit of baby powder into it, because starch is too sticky and heavy,” says Gillian Albinski, the property ...

There was a follow up tweet about this: The IP address equivalent of 555 phone numbers is actually well documented in RFC5737. e.g. 203.0.113.11 is TV safe. http://tools.ietf.org/html/rfc5737#section-3 Which links to Documentation Address Blocks The blocks 192.0.2.0/24 (TEST-NET-1), 198.51.100.0/24 (TEST-NET-2), and 203.0.113.0/24 ...

Normally, no, you could not grow plants in Martian soil... but adding nutrients to the soil makes it perfectly usable. There's a great article about it on Modern Farmer: And, yes, it is possible to grow plants on Mars—kind of. Alone, Martian soil doesn’t have the necessary elements for plant life. “The main thing that’s not in Martian soil is a bunch of ...

Disclaimer: Violence is stupid and dangerous. A blow to the skull is often fatal. I wouldn't say it's easy, but there are several sweet spots on the skull that, when hit with sufficient force, is almost guaranteed to cause unconsciousness. I would suggest the upper part of the jaw bone or the temple. Both places are connected to the brain stem through ...

Recycling effects is a very common tactic in post-production. Once you have an effect that works great, it's simply cheaper and faster to reuse it than to reinvent the wheel over and over again, especially when 99% of the viewers won't notice it. You are one of the few people who noticed that this particular sound was recycled, but there are hundreds of ...

Yes, it's possible. In theory, it's possible to produce a 100% pure sample of any substance; if you isolated and removed any molecules that were not those of your target chemical. The trick is that it's usually very impractical to do so, for various reasons. The cost of purifying chemicals rises sharply as the purity goes up, because you need more expensive ...

His hair is partly burned off in an explosion. As you can (just about) see when he's chasing down Kyle and Sarah after the shootout in Tech Noir, his hair is long and flowing: Then when Sarah and Kyle get to their car, Kyle shoots at the petrol tank of a car in front of him and blows it up, then The Terminator jumps through the flames and catches fire: ...

The appearance of the black hole in Interstellar was not created arbitrarily. It was actually modeled using the real relativistic equations describing the path of light in the gravitational field of a super-massive black hole spinning at near the speed of light. As a result, it may be the most accurate depiction we have to date of what such an object might ...

Some Banks fall under the jurisdiction of certain authorities: it's safe to say criminals would not choose those banks, instead opening an account with a specialized authority.

Apparently Keanu Reeves, after the Matrix experience, got hooked on Martial Arts. But as far as the movie is concerned, we're talking about choreography (you learn moves as when you do with dancing). According to The Matrix FAQ on Imdb: The actors that were hired had some kind of physical background; Carrie Anne-Moss was a dancer and Keanu Reeves used ...

Man Vs Wild isn't real. If you watch the DVD extras, Bear introduces us to his team. There's a rope expert, a survival food expert, a medical guy etc. The point of the show is to show us how to survive in those situations. And at the beginning of each show there's a disclaimer stating that he is accompanied by a team of experts. He builds his shelters to ...

First, movies are unrealistic in these regards. It's no different than the "realism" of zooming in on security cameras and cleaning up the images. It's just not realistic, but it makes for good entertainment and helps with plot advancement. However, that said, there are plenty of people with easy-to-guess passwords. I know plenty of otherwise intelligent ...

I'm gonna have to go against the grain here. As someone who has trained boxing for years, no, it's not even close. It is extremely hard to do in real life, and people don't stay down more than a few seconds. In my entire boxing "career", I've taken thousands of blows, and I've never lost consciousness. I've hit other people thousands of times, and only like ...

First it was 4.2 on Richter scale. 4.2 MW is just unit of energy. I don't think the bomb would have caused a tsunami though - it may have caused huge waves but they wouldn't have reached Gotham. The Bomb was capable of destroying 6 mile radius area. So assuming that bomb was dropped 6 miles away from Gotham in the ocean, the water would have absorbed ...
