Can you recommend some works of most advanced science fiction?

Sure. 'Hyperion' by Dan Simmons is quite difficult. It weaves together multiple storylines and has a lot of deep philosophical and theological discussions within its science - fictional framework. Another good one is 'The Stars My Destination' by Alfred Bester. Its unique narrative style and concepts like teleportation presented in a very complex way can be a real brain - teaser. '2001: A Space Odyssey' by Arthur C. Clarke is also tough in the sense that it's very open - to - interpretation and the scientific and metaphysical ideas are intertwined in a rather abstract manner.

The Daleks from 'Doctor Who' are often considered very advanced. They are a race of cyborgs in armored casings. Their technology allows them to travel through time and space, and they possess powerful energy weapons. They also have a strict hierarchical society centered around their goal of universal domination.

The Culture from Iain M. Banks' novels. It has extremely advanced technology, such as the ability to manipulate matter at a fundamental level. Their ships can create artificial environments and they have a post - scarcity economy, where people are free to pursue knowledge and personal growth without worrying about basic needs.

One characteristic is highly imaginative concepts. For example, in advanced science fiction, we often see new forms of space travel like warp drives or wormhole navigation. It also features complex and believable future societies with different political, social and technological structures. Another aspect is the exploration of deep philosophical questions such as what it means to be human in a world where technology can change our very nature.

I'd recommend 'Snow Crash' by Neal Stephenson. It's a work that combines a lot of different scientific and technological concepts. It has elements of virtual reality, linguistics, and sociology. Also, 'The Three - Body Problem' by Liu Cixin is a masterpiece. It deals with complex astrophysics concepts and the possible existence of extraterrestrial civilizations in a very intelligent way.

The Culture from Iain M. Banks' novels. They are a post - scarcity society with extremely advanced technology. Their ships are sentient and they can manipulate matter and energy on a vast scale. They are also very peaceful, using their advanced capabilities to help other species rather than dominate them.

The concept of artificial superintelligence is very exciting in science fiction. A super - intelligent AI can have a profound impact on the world in science fiction stories, whether it's for good or bad. And the technology of energy shields is also cool. It can protect spaceships or cities from various attacks, which often plays an important role in many science fiction battles.

One characteristic could be advanced energy manipulation. For example, in many sci - fi stories, the most advanced civilizations can harness energy from stars or even from subspace. Another is the mastery of genetic engineering, like creating super - intelligent or super - strong beings.

I'm not sure specifically which '80' you mean here. If it's about works from the 1980s, 'Blade Runner' is a classic. It has a very unique vision of a future Los Angeles and explores themes of artificial intelligence and what it means to be alive.

Edgar Allan Poe also dabbled in what could be considered early science fiction in the 1800s. His stories often had elements of the macabre combined with scientific or technological concepts. For example, 'The Unparalleled Adventure of One Hans Pfaall' which involved a journey to the moon in a rather unique and early take on space travel stories.
