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.
One of the best is 'The Time Machine' by H.G. Wells. It's a classic that introduced many concepts of time travel. The story follows an inventor who travels far into the future and discovers a society divided into two species, the Eloi and the Morlocks. Wells' vivid descriptions and thought - provoking ideas about evolution and class struggle in the future make it a must - read.

One characteristic is the integration of science and fiction in a unique way. They might not always be strictly scientific in terms of the time travel mechanism but still make it seem plausible within the context of the story. They also often explore different historical periods. This is seen in many of the 'Doctor Who' novelizations. The Doctor travels to various times in history, from ancient civilizations to the far future, and the stories are as much about the historical settings as they are about the time travel concept itself.
In some science fiction novels, historians might time travel through advanced technological devices like time machines. For example, in H.G. Wells' 'The Time Machine', a device is used to travel through time. Historians could use such a machine to directly visit different historical periods to observe and study events first - hand.
Some great time travel science fiction novels include 'Time and Again' by Jack Finney. It has a really interesting take on time travel where the protagonist travels back to 19th - century New York. 'Kindred' by Octavia Butler is also a notable one. It uses time travel to explore issues of race and slavery as the main character is transported back to the antebellum South. Additionally, 'Replay' by Ken Grimwood is about a man who repeatedly relives his life, which is a unique form of time travel in a way.

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.
