How are rebreathers in science fiction different from real - life ones?

In science fiction, cryogenic chambers are often more advanced and have fewer limitations. They can keep people in suspended animation for centuries or even millennia without any damage to the body or mind, while real - life cryogenic technology is still in its early stages and has many challenges. For example, currently, we can't ensure that the brain will be intact after long - term freezing.

Well, one big difference is the portrayal of the forensic scientists themselves. In fiction, they are often super - heroes who can crack any case with their forensic skills. In reality, they are highly trained professionals but face many limitations such as budget constraints and imperfect evidence. And in fictional stories, forensic evidence is usually the key that directly leads to the culprit, while in real - life investigations it's just one part of a complex web of evidence and witness testimonies.

Well, the ones from science fiction are often much more extreme. Real minerals and metals have known properties and limitations. But in science fiction, like the unobtainium in Avatar, it has properties that are highly exaggerated for the story's needs. It's super - strong, super - valuable, and has a role in the plot that a real - world material couldn't play without major technological leaps.

Rebreathers in science fiction can have various functions. They might enable characters to explore areas with toxic atmospheres. Some rebreathers are depicted as advanced devices that can recycle and purify air for an extended period, which is crucial for long - term space missions or deep - sea dives in fictional stories. Also, they can be a key element in the survival kit of a stranded astronaut or a deep - sea explorer.

The most obvious difference is the technology. Real - life castles have moats, drawbridges, and thick stone walls for defense. But in science fiction, castles might have force fields and laser turrets. Also, science - fiction castles can exist in places like other galaxies or on asteroid belts, which is impossible for real castles.

Science - fiction pacifists are often in more extreme situations compared to real - life ones. They might be in a universe where entire planets are at war or there are races with completely different values. Real - life pacifists usually work within the framework of international laws and human society. In science fiction, pacifists may have to come up with unique solutions like using time - travel to prevent a war that has been prophesied. They also might be part of a civilization where non - violence is a very rare concept, so they face more challenges in getting their ideas across.

Real - life spacecraft are much more limited in terms of speed and capabilities compared to those in science fiction. For example, we don't have warp drives yet.

Well, in science fiction, drones are often much more advanced. They might have capabilities like invisibility or super - fast speed which real - life drones don't have. For example, a sci - fi drone could be invisible to the naked eye and be able to zip through the air at incredible speeds.

Sci - fi caverns often hold otherworldly ecosystems not found in real caverns. Real caverns have their own unique ecosystems, but in science fiction, they can be filled with plants and animals that are completely alien, with strange shapes and abilities that defy biological understanding.

In science fiction, EMTs often deal with non - human patients. This is a huge difference from real - life EMTs who mainly deal with humans. For example, in a sci - fi movie, an EMT might be treating a lizard - like alien with three hearts.
