supports: Time travel is the concept of movement (such as by a human) between certain points in time, analogous to movement between different points in space, typically using a hypothetical device known as a time machine, in the form of a vehicle or of a portal connecting distant points in time. Time travel is a recognized concept in philosophy and fiction, but traveling to an arbitrary point in time has a very limited support in theoretical physics, and usually only in conjunction with quantum mechanics or wormholes, also known as Einstein-Rosen bridges. In a more narrow sense, one-way time travel into the future via time dilation is a well-understood phenomenon within the frameworks of special relativity and general relativity, but advancing a large amount of time is not feasible with current technology. The concept was touched upon in various earlier works of fiction, but was popularized by H. G. Wells' 1895 novel "The Time Machine", which moved the concept of time travel into the public imagination, and it remains a popular subject in science fiction. Edward Elmer Smith (also E. E. Smith, E. E. Smith, Ph.D., E. E. "Doc" Smith, Doc Smith, "Skylark" Smith, orto his familyTed; May 2, 1890  August 31, 1965) was an American food engineer (specializing in doughnut and pastry mixes) and an early science-fiction author, best known for the "Lensman" and "Skylark" series. He is sometimes called the father of space opera. Science fiction (often shortened to SF, sci-fi or scifi) is a genre of speculative fiction, typically dealing with imaginative concepts such as futuristic science and technology, space travel, time travel, faster than light travel, parallel universes, and extraterrestrial life. Science fiction often explores the potential consequences of scientific and other innovations, and has been called a "literature of ideas." It usually avoids the supernatural, and unlike the related genre of fantasy, historically science fiction stories were intended to have a grounding in science-based fact or theory at the time the story was created, but this connection is now limited to hard science fiction. Fantasy Press was an American publishing house specialising in fantasy and science fiction titles. Established in 1946 by Lloyd Arthur Eshbach in Reading, Pennsylvania, it was most notable for publishing the works of authors such as Robert A. Heinlein and E. E. Smith.
