name something that used to be science fiction

Genetic engineering. It was once a far - fetched idea from science fiction novels. Scientists now can manipulate genes to create genetically modified organisms, develop gene therapies for certain diseases, and even explore the possibility of cloning. This has opened up new frontiers in medicine and agriculture.

Smartphones. In the past, the idea of having a small device that could not only make calls but also access the internet, play music, take high - quality photos, and run countless apps was pure science fiction. But now, smartphones are an essential part of our daily lives.

It could be science fiction. But it might also fall into other genres like fantasy or dystopian.

Sure. The ray gun is a classic science fiction instrument. It's often used by heroes and villains alike in various sci - fi stories. Another one is the gravity boots. They let characters walk on walls or ceilings by manipulating gravity. And the robotic arm is also quite common. It can be used for various tasks, from delicate surgeries to heavy - duty construction in science fiction scenarios.

One well - known instance is in some science fiction novels that envision future space exploration. Elon Musk's real - life efforts in SpaceX have inspired fictional stories where his name might be dropped as a sort of visionary figure who paved the way for interplanetary travel in those fictional universes.

Science fiction is characterized by stories that explore scientific or technological possibilities. It might feature futuristic settings, scientific breakthroughs that haven't happened yet, or deal with the consequences of such advancements. For example, a story about humans colonizing Mars or robots taking over the world could be considered science fiction.

One example is gene editing. In the past, the idea of precisely modifying genes was only in science fiction stories like creating superhumans. But now, with CRISPR - Cas9 technology, we can edit genes relatively easily. Another is virtual reality. It was once a far - fetched idea in sci - fi, but now we have VR headsets that can immerse us in virtual worlds. Also, smart homes were once science fiction. Now, we can control lights, thermostats, and security systems with our smartphones.

Anaglyph is often used in science fiction to create a 3D effect. For example, in some science fiction movies, anaglyph glasses are used to make the viewers feel like they are in the middle of the futuristic scenes. It gives a sense of depth to the otherwise flat images on the screen.

Litany in science fiction is used to set a mood. For instance, a spooky litany in a horror - based science - fiction story can make the atmosphere more eerie. It can also be used to show the unity of a group. When all members of a crew recite a litany together, it shows their bond.

In science fiction, petroglyphs can be used as a mystery element. For example, in some stories, they might be ancient alien markings that hold the key to advanced technology or a long - lost civilization. They add an air of the unknown and ancientness to the fictional world.
