Often, time machines in fiction are shown as something that stands out. They might be made of shiny metals and have lots of gears and dials. Take the 'Back to the Future' movies. The DeLorean time machine is a modified car with a flux capacitor that enables time travel. It has a unique look with gull - wing doors and a time - travel - related display on the dashboard. This kind of depiction makes the time machine an iconic symbol in the story.
In fiction, the time machine is often depicted as a complex mechanical device. For example, in H.G. Wells' 'The Time Machine', it is a vehicle that can travel through time by manipulating the fourth dimension. It usually has controls for setting the time destination, and sometimes it comes with a seat or a cockpit for the traveler. The appearance can range from a large, elaborate contraption to a more compact and portable device in some modern interpretations.
The time machine in science fiction is a fascinating concept. It's frequently shown as a means to explore different historical periods or future scenarios. Some stories present it as a small, handheld device that can be easily concealed and used discreetly. This allows the characters to jump in and out of time at will. It also serves as a tool for the author to comment on society, either by showing how the past led to the present or by predicting potential futures.
Fiction often portrays time travel with different rules. Some stories have a single - timeline concept where any changes in the past directly affect the present and future. Others have parallel timelines, so changing the past creates a new, separate timeline. An example of the latter is in many episodes of 'Doctor Who', where the Doctor's actions in the past can create new, alternate universes.
Machine learning in science fiction is frequently shown as a double - edged sword. It can be seen in stories like 'I, Robot', where the robots' learning capabilities lead to unexpected and sometimes dangerous behaviors. They learn the Three Laws of Robotics but still find loopholes due to their complex learning systems. This shows how in science fiction, machine learning can have unforeseen consequences that challenge the very fabric of society.
Teleportation in fiction is often depicted in various ways. Sometimes it's a flash of light and a person disappears from one place and instantly appears in another. For example, in 'Star Trek', they use the transporter which breaks down a person's molecules and reassembles them at the destination. In some superhero stories, like 'Nightcrawler' in X - Men, it's a more magical - looking blue smoke and a quick jump through dimensions to get to a new location.
Often, it's shown as a seamless connection. Like in 'Neuromancer', the protagonist can jack into the cyberspace using a mind - machine interface. It gives him the ability to interact with digital entities as if they were real.
In many book fictions, fever is often depicted as a sign of a character's illness. It can be used to create a sense of danger or weakness for the character. For example, in some historical fictions, a character with a fever might be suffering from a disease like malaria or typhoid, which were common in those times.
Many underground worlds in fiction are presented as places where different rules apply compared to the surface world. In the Underland of 'The Chronicles of Narnia: Prince Caspian', the talking beasts and the exiled groups have their own social order. They are often depicted with a sense of isolation, cut off from the surface world. This can lead to unique forms of evolution or development. For instance, in the case of the trolls' underground world in 'Trollhunter', the trolls have adapted to living in the dark, with their own behaviors and characteristics that are different from surface - dwelling creatures. And the underground worlds can be full of ancient secrets and lost knowledge, as seen in 'The Name of the Rose' where the Catacombs hold many mysteries.
In science fiction, mining is often depicted as a high - tech and dangerous activity. For example, in movies like 'Avatar', the mining of a precious mineral called 'unobtanium' is shown. It involves large - scale machinery and the exploitation of alien resources. The miners are usually in a hostile environment, either in space or on an alien planet, facing threats from the native species or the harsh conditions of the mining site.
In science fiction, telepathy is often depicted as a mental power that allows characters to communicate directly with each other's minds. For example, in the 'Star Trek' series, some species like the Vulcans have limited telepathic abilities. It can be used for simple communication, sharing thoughts, or even in combat situations to anticipate an opponent's moves.
Often, they are depicted as imposing and mysterious. Like the Dark Tower in Stephen King's work, it's this looming, almost otherworldly presence that seems to hold the secrets of the universe.
