Time travel is the hypothetical activity of traveling into the past or future. Time travel is a widely recognized concept in philosophy and fiction, particularly science fiction. In fiction, time travel is typically achieved through the use of a hypothetical device known as a time machine. The idea of a time machine was popularized by H. G. Wells' 1895 novel The Time Machine.It is uncertain if time travel to the past is physically possible, and such travel, if at all feasible, may give rise to questions of causality. Forward time travel, outside the usual sense of the perception of time, is an extensively observed phenomenon and well-understood within the framework of special relativity and general relativity. However, making one body advance or delay more than a few milliseconds compared to another body is not feasible with current technology. As for backward time travel, it is possible to find solutions in general relativity that allow for it, such as a rotating black hole. Traveling to an arbitrary point in spacetime has very limited support in theoretical physics, and is usually connected only with quantum mechanics or wormholes.

A microscopic multi-celled organism has returned to life after being frozen for 24,000 years in Siberia, according to new research.Scientists dug up the animal known as a bdelloid rotifer from the Alayeza River in the Russian Arctic.
Teleportation, time travel, antimatter and wireless electricity. It all sounds far-fetched, more fiction than fact, but it's all true. Everybody is used to science fiction featuring science that seems, well, not very scientific.
On the net since 1999, Andy's Anachronisms is devoted to exploring the themes of time travel and alternate history in books, movies, television, and pop culture in general.
Cryonics (from Greek: κρύος kryos meaning 'cold') is the low-temperature freezing (usually at −196 °C or −320.8 °F or 77.1 K) and storage of a human corpse or severed head, with the speculative hope that resurrection may be possible in the future.
Hi there! Writing a letter to the future can be a powerful experience. And receiving a surprise letter from the past can be an even more powerful experience. Check out the testimonials all of the people who agree!.
From millennium-skipping Victorians to phone booth-hopping teenagers, the term time travel often summons our most fantastic visions of what it means to move through the fourth dimension. But of course you don't need a time machine or a fancy wormhole to jaunt through the years.
Virtual reality can be used to give the illusion of going "back in time", according to an exploratory study. In this virtual world, subjects were able to reduce how many people a gunman killed, an event they had unknowingly been part of.
Forget Dr Who; Chris Wild is a real Time Lord. The 40-year-old ex-museum curator and entrepreneur describes himself as a retronaut - someone who goes back in time "using just his perception".
Time travel is the concept of movement between certain points in time, analogous to movement between different points in space by an object or a person, typically with the use of a hypothetical device known as a time machine.
Physicists have confirmed the ultimate speed limit for the packets of light called photons - making time travel even less likely than thought. The speed of light in vacuum is the Universe's ultimate speed limit, but experiments in recent years suggested that single photons might beat it.
For budding time travellers, the future (or should that be the past?) is starting to look bleak. Hypothetical tunnels called wormholes once looked like the best bet for constructing a real time machine.
The men who left a message in a bottle under floorboards in an Edinburgh house were joiners who helped build the Victorian property - and had 11 children between them.
A conservation team in the US state of Virginia has opened a box containing Confederate war memorabilia believed to be more than 130 years old. It contained newspapers, books and ammunition dated to the US Civil War.
