travel in science fiction

It's a bit of both. Some theories in physics, like Einstein's theory of relativity, suggest that time can be warped under certain conditions, which is scientific. However, we haven't actually achieved practical time travel yet, so in most cases it remains in the realm of science fiction. For example, the idea of using a time machine to go back and change historical events is still very much a fictional concept.

Well, in hard science fiction, interstellar travel is tough. For example, the time dilation effect from traveling at relativistic speeds is a big deal. Astronauts might age much slower than people on Earth. Also, the need for self - sustaining ecosystems on long - journey spacecraft is crucial. Without proper life - support systems, survival becomes impossible.

When it comes to interstellar travel in hard science fiction, there are various technological concepts. Ion drives are a possibility. They can provide continuous thrust over long periods. There's also the idea of using black holes' gravitational slingshot effect to gain speed. However, all these technologies are still far from being realized in real life and require a lot of scientific breakthroughs.

One great time travel science fiction book is 'The Time Machine' by H.G. Wells. It's a classic that introduced the concept of time travel in a very imaginative way. The protagonist travels to the far future and witnesses the evolution of humanity in disturbing ways. Another is 'A Wrinkle in Time' by Madeleine L'Engle. It combines time travel with elements of fantasy and adventure, following a young girl's journey through different dimensions and times to save her father. Also, '11/22/63' by Stephen King is excellent. It's about a man who travels back in time to try to prevent the assassination of President Kennedy.

Fiction. Modern science has not been able to prove that time travel is possible. Scientists have explored concepts like time dilation, but this is not the same as actual time travel. Time dilation occurs in situations like when an object is moving at a high speed relative to another, but it doesn't allow for traveling to different historical or future periods in the way we imagine time travel.

It also helps in understanding human nature better. When characters travel through time, their reactions to different historical periods can reveal a lot about their values and beliefs. In 'A Connecticut Yankee in King Arthur's Court', the main character's attempts to modernize the past show his confidence in his own time's superiority. Moreover, time travel in science fiction has inspired real - world scientific thinking. Scientists sometimes get ideas from fictional time - travel concepts, even if they are not yet possible in reality.
