What are the common scenarios involving retroviruses in science fiction?

In science fiction, retroviruses are often depicted as a major threat to humanity. They can be shown as causing widespread pandemics, mutating humans into strange creatures, or being used as biological weapons. For example, in some stories, a retrovirus might be accidentally released from a lab and quickly spread across the globe, decimating the population.

One common scenario is the accidental creation of a dangerous mutant in the genetics lab. This mutant then escapes and causes chaos. Another is the discovery of a way to cure all diseases through genetic manipulation in the lab, but there are moral and ethical debates about who gets the treatment first.

In a dystopian science fiction, Trump's use of Twitter (or a fictional equivalent) could be a means of mind control. Every tweet is a form of subliminal messaging that brainwashes the public into believing whatever he wants. The population has lost the ability to think critically, and any form of dissent is quickly silenced, creating a very Orwellian - like dystopia.

Common scenarios of gene editing in science fiction include the correction of genetic disorders on a large scale. This could mean that in a fictional world, every baby is genetically 'perfect' thanks to gene editing. Another scenario is the use of gene editing to enhance cognitive abilities far beyond normal human levels. This might lead to a society where there is a huge gap between the 'genetically enhanced' and the 'naturals'. Additionally, gene editing is sometimes used to adapt humans to extreme environments, like deep - sea or outer - space environments in science fiction stories.

One common scenario is when a spaceship is about to be captured by the enemy. To prevent the enemy from getting valuable technology or information, the crew activates the self - destruct mechanism. For example, in the 'Star Trek' series, some ships have this option. Another scenario could be a malfunctioning super - weapon or research facility that poses a great threat. To avoid a catastrophe, self - destruct is triggered. In some cyberpunk - themed science fiction, a self - aware AI that realizes it's being misused might choose to self - destruct to prevent further harm.

In science fiction, one common scenario is creating an army of clones for warfare. For example, in some stories, evil organizations clone a large number of soldiers who are identical in strength and skills, which poses a great threat to the world. Another scenario is using clones as replacements. A person might create a clone of themselves to take over their life when they are tired of it, but this often leads to identity crises and moral dilemmas.

One common scenario is in steampunk - inspired science fiction. Here, gas lights are a staple. They fit well with the aesthetic of a world that combines Victorian - era technology with a more advanced, often alternate - history take on science. The gas lights in such settings are often elaborate and ornate, lighting up cobbled streets and grand, steam - powered machines.

One common storyline is about the discovery of ancient ruins on a planet in the Altair system. Scientists or adventurers explore these ruins, which might hold the secrets of an extinct civilization. They have to decipher the strange symbols and technologies left behind.

One common storyline is the discovery of a hermaphrodite species. This often leads to a reevaluation of human understanding of biology and gender. For example, in a space exploration - themed story, humans encounter an alien race that is hermaphroditic, and they have to learn to communicate and interact with them, which challenges their own cultural and social norms.

Another scenario is when an alien spaceship arrives on Earth. This can range from a peaceful arrival, like in 'Close Encounters of the Third Kind', where the aliens seem to be interested in communication, to a more menacing one as in 'Independence Day' where the aliens come to invade.
