Clarke, often characters will try to hail unknown entities. It's a way to start a relationship, whether friendly or hostile, with the mysterious 'them'. For example, a spaceship crew might hail an unidentified object in space. This action can lead to discovery, adventure, or danger, which are all common elements in science fiction.

FTL, or Faster - Than - Light travel, is a common concept in science fiction. It allows characters to traverse vast distances in space quickly.

For example, in some alien planet descriptions, fractal patterns might be used to depict the strange and complex geological formations. It gives a sense of something that is both beautiful and alien at the same time.

In 'Arrival', the linguist Louise Banks has to figure out a way to communicate with aliens to prevent a potential global catastrophe. The whole idea of being able to understand an alien language and use it to change the future is a very tenuous and high - stakes situation, similar to what we might consider a 'hail mary' in science fiction.

The first use of science fiction? That's a tricky one. But one of the very early uses was probably to make sense of the world around people in a new way. Back in the day, writers started using science - fictional ideas to comment on society and progress. For example, in the early works, they might have been exploring the idea of new forms of transportation or communication. 'Frankenstein' was a big step in this, as it not only had scientific elements like the creation of life but also delved deep into moral and ethical questions that came with scientific progress. This early use set the stage for science fiction to become a genre that would continue to explore the relationship between science, society, and the human psyche.
