Are wormholes pure science fiction or have some scientific basis?

Yes, wormholes are often considered science fiction. They are theoretical passages through spacetime that have not been proven to exist in reality. Most of our knowledge about wormholes comes from the realm of science fiction novels, movies, and TV shows, like 'Interstellar' which features a journey through a wormhole.

In science fiction, astral projection is often a wild concept with little scientific basis in the real world. It's mainly a product of creative imagination to explore ideas like out - of - body experiences and different planes of existence.

As of now, they are mostly science fiction. We don't have any evidence that wormholes actually exist. They are a theoretical construct based on complex physics equations. So, until proven otherwise, we can think of them as science fiction.

Dragons are definitely fiction. They're these amazing, fantastical creatures that we come across in fantasy literature and games. There's no scientific evidence or real-life sightings to suggest they're anything but made-up for entertainment and storytelling purposes.

Hypersleep is mostly fictional. There's no solid scientific evidence for it as we know it in science fiction.

No, currently there is no scientific basis for pre life stories. The idea of pre life memories is more in the realm of the spiritual and philosophical. Scientists deal with facts that can be measured, observed, and replicated. Memories of pre life, which are often anecdotal and vary greatly from person to person, don't fit into the scientific method. However, that doesn't stop people from believing in them on a personal or spiritual level.

A novel with a scientific basis but a wrong explanation from a physical point of view was considered soft science fiction. Soft science fiction usually contains some technological elements, but the explanation of these technologies often does not completely conform to the laws of physics. In this type of novel, the development of technology was often due to supernatural reasons or attempts based on imagination of the future. For example, the " Galaxy Empire " series and " 2001: A Space Oasis " were all masterpieces of soft science fiction. Hard science fiction, on the other hand, emphasized the physical basis of technology and its practical application. In this type of novel, the development of technology was often based on the need to solve real-life problems or the prospect of future technology. For example, the " Three-Body Problem " series and " Wandering Earth " were all representative works of hard science fiction. Although some soft science fiction novels might contain some technological elements that did not conform to the laws of physics, most soft science fiction novels paid more attention to the imagination of the future and the exploration of technology rather than simply applying the laws of physics.

A science fiction novel about wormholes or stargates was called the Star Trek series. The series was written by George R. R. Martin, which told the story of a human-created interstellar exploration ship, Star Trek, leading the crew to explore the unknown interstellar space. The series contained many sci-fi elements about wormholes and stargates, and became a classic choice for many sci-fi fans.

There was currently no conclusive scientific basis for the human blood buns. In the old days, folk superstitions believed that human blood could cure lung cancer (lung cancer), and some people bought steamed buns dipped in human blood from the executioner to cure the disease. However, the Chinese medical community had gradually stopped using human blood as medicine in the Ming Dynasty, and Li Shizhen clearly opposed the use of human blood or human organs as medicine in the Compendium of Materia Medica. Therefore, the human blood bun was more of a product of superstition and lacked scientific evidence to support its treatment effect. Modern medicine already had more scientific and effective methods to treat lung cancer, such as anti-tumor drugs and immune therapy. Therefore, the treatment effect of the human blood bun had not been verified by science.

One scientific fact often found in science fiction is the concept of relativity. For example, in many space - themed science fictions, time dilation as predicted by Einstein's theory of relativity is depicted. When spaceships travel at near - light speeds, time passes more slowly for the astronauts on board compared to those on Earth. This has been a staple in science fiction stories to create interesting plotlines about time differences between space travelers and those left behind on the home planet.
