things that only happen in science fiction

Time travel is also something that only occurs in science fiction. While we can theoretically understand the concept, actually traveling back and forth in time like in 'Back to the Future' is not possible yet. There are so many paradoxes associated with it, like the grandfather paradox. If you go back in time and accidentally prevent your grandfather from meeting your grandmother, then how could you exist in the first place? It's a mind - boggling concept that remains in the realm of science fiction for now.

Mind - reading machines. Although we are making progress in understanding the brain, we don't have a device that can simply read someone's thoughts like in some science fiction novels. It's a very complex and still mostly mysterious area. Our thoughts are not like radio waves that can be easily intercepted and decoded.

No. Mermaids also have a strong presence in mythology. In many ancient cultures' mythologies, mermaids were part of their belief systems, not just fictional stories for entertainment like in science fiction.

Definitely not. Werewolves are not only science fiction. They are deeply ingrained in mythology and superstition from various cultures around the world. In ancient times, people believed in the existence of werewolves as real entities, not just as a fictional concept in a science - based story. Even today, in some horror and supernatural genres that are not strictly science - related, werewolves play a major role.

No. While superpowers are commonly associated with science fiction, there are some real - life examples that could be considered 'superpowers' in a sense. For instance, people with eidetic memory have an extraordinary ability to recall details vividly. However, the extreme and often unrealistic superpowers like flying or shooting energy beams are mainly in science fiction.

Definitely not. Although science fiction is full of all kinds of alien concepts, there are actual scientific theories and studies related to the existence of extraterrestrial beings. For instance, the discovery of exoplanets in the habitable zone makes it seem more likely that there could be some form of life out there, not just in the fictional world of science - fiction stories.

One of the new things in science fiction could be the exploration of post - apocalyptic worlds in unique ways. For example, some recent works focus on how society rebuilds not just physically but also culturally after a major catastrophe. Another new aspect is the use of advanced artificial intelligence concepts that are more in - depth and complex, such as AI entities having emotions and moral compasses.

One thing about science fiction is its ability to envision future technologies. Another is that it often explores different social and political systems. It also frequently features alien species. Fourthly, it can be a great medium for exploring moral and ethical issues. And finally, science fiction has the power to inspire real - world scientific research.

It's both. 'Stranger Things' combines elements of science fiction like the existence of an alternate dimension (the Upside Down) with scientific experiments gone wrong. It also has fantasy elements such as the psychic powers of Eleven. These two genres blend together to create a unique and captivating story.

Definitely! Stranger Things is firmly in the science fiction genre. It builds its story around concepts such as time travel, mind control, and hidden scientific experiments gone wrong. All these aspects contribute to its science fiction nature.
