There are several. The ethics of artificial intelligence is a big one. As seen in 'Ex Machina', where the creation of an AI with consciousness leads to questions about its rights and how it should be treated. Then there's the ethical consideration of genetic engineering. In some science fiction, characters modify their genes or the genes of others, and this brings up issues about playing God and the long - term effects on society. Also, the ethics of information control can be found, like in 'Snow Crash' where the control and spread of information has ethical implications.
One common theme is the ethics of power. In many science fiction stories, characters or groups have extraordinary power, such as in 'X - Men' where mutants have special abilities. The ethical question is how they should use that power, for good or for evil. Another is the ethics of survival. In post - apocalyptic science fiction like 'The Walking Dead', people face moral choices in order to survive.
One common theme is space exploration. For example, in '2001: A Space Odyssey', it shows humans traveling to outer space and encountering the unknown. Another theme is artificial intelligence. 'Blade Runner' explores the idea of androids and what it means to be human in relation to them. And time travel is also a popular theme, like in 'Back to the Future' where the main character goes back and forth in time, changing the course of history.
Alien life forms are a frequent theme. Sci - fi stories may show us friendly aliens like in 'E.T. the Extra - Terrestrial' or hostile ones as in 'Alien'. Post - apocalyptic worlds are also common, such as the one in 'Mad Max' series. These themes allow us to explore different possibilities and challenges in a fictional setting.

Additionally, technological advancements and their consequences on society are themes, like how in 'The Matrix' technology has enslaved humanity.
Time travel is a frequent theme in science fiction. It allows for exploring different eras, changing the past or seeing the future. Space exploration is also a big theme.

And finally, environmental issues are sometimes addressed in science fiction, like how a polluted Earth might look in the future or how we can save it.
Another theme might be the relationship between man and machine. As industrialization was well underway in 1866, science fiction of that time could have been exploring how humans interact with new technologies and machines. This could range from the fear of being replaced by machines to the idea of humans using machines to enhance their capabilities. Also, there could be themes related to social change. With the world evolving rapidly during that period, science fiction might have been speculating on how society would be different in the future due to scientific advancements.
In science fiction, the theme of alien life forms is quite prevalent. Books and movies often depict strange and intelligent alien species, like in 'E.T. the Extra - Terrestrial'.
