The "present" view

Presentism holds that neither the future nor the past exist - that the only things that exist are present things, and there are no non-present objects. Some have taken presentism to indicate that time travel is impossible for there is no future or past to travel to; however, recently some presentists have argued that although past and future objects do not exist, there can still be definite truths about past and future events, and that it is possible that a future truth about the time traveler deciding to return to the present date could explain the time traveler's actual presence is the present. This view is contested by another contemporary advocate of presentism, Craig Bourne, in his recent book " A Future for Presentism" although for substantially different (and more complex) reasons. In any case, the relativity of simultaneity in modern physics is generally understood to cast serious doubt on presentism and to favor the view known as four dimensionalism (closely related to the idea of block time) in which past, present and future events all coexist in a single spacetime.

General Relativity

The theory of general relativity does suggest scientific grounds for thinking backwards time travel could be possible in certain unusual scenarios, although arguments from semiclassical gravity suggest that when quantum effects are incorporated into general relativity, these loopholes may be closed. These semiclassical arguments led Hawking to formulate the chronology protection conjecture, suggesting that the fundamental laws of nature prevent time travel, but physicists cannot come to a definite judgment on the issue without a theory of quantum gravity to join quantum mechanics and general relativity into a completely unified theory.

Tourism In Time

Stephen Hawking once suggested that the absence of tourists from the future constitutes an argument against the existence of time travel (a variant of the Fermi paradox). Of course this would not prove that time physically impossible, since it might be that time travel is physically possible but that it is never in fact developed (or was cautiously never used); and even if it is developed, Hawking notes elsewhere that time travel might only be possible in a region of spacetime that is warped in the right way, and that if we cannot create such a region until the future, then time travelers would not be able to travel back before that date, so "This picture would explain why we haven't been over run by tourists from the future. Carl Sagan also once suggested the possibility that time travelers could be here, but are disguising their existence or are not recognized as time travelers.

Time Travel In Theory

Some theories most notably special and general relativity, suggest that suitable geometries of spacetime, or specific types of motion in space, might allow time travel into the past and future if these geometries or motions are possible. In technical papers physicists generally avoid the commonplace language of "moving" or "traveling" through time ("movement" normally refers only to a change in spatial position as the time coordinate is varied), and instead discuss the possibility of closed timelike curves, which are wordlines that form closed loops in spacetime, allowing objects to return to their own past. There are known to be solutions to the equations of general relativity that describe spacetimes which contain closed timelike curves, but the physical plausibility of these solutions is uncertain.

Time Travel

Time Travel is the concept of moving between different moments in time in a manner analogous to moving between different points in space, either sending objects (or in some cases just information) backwards in time to a moment before the present, or sending objects forward from the present ti the future without the need to experience the intervening period ( at least not at the normal rate). Some interpretations of time travel also suggest that traveling backwards in time might take one to a parallel universe whose history could begin to diverge from the traveler's history after the moment the traveler arrived in the past.

Although time travel has been a common plot device in fiction since the 19th century, and one-way travel into the future is arguably possible given the phenomenon of time dilation based on velocity in the theory of special relativity (exemplified by the twin paradox) as well as gravitational time dilation in the theory of general relativity, it is currently unknown whether the laws of physics would allow backwards time travel. Any technological device, whether fictional or hypothetical, that is used to achieve two-way time travel is known as a time machine. (Taken from: wikipedia.org)

Mothman Sighting

I don't know whether this is real or fake because it was pictures slideshow and I can't say its fake or real. I grabbed the video from Youtube.com. It depends on you whether you want to believe it or not because we haven't seen the real footage of Mothman recently. But many people connect Mothman with bad predictions (when we see mothman, bad things will happen in a few minutes after that) and some say Mothman is Angel of Death. Until now, we do not know about the existence of Mothman.

Mothman Analysis

There are several theories concerning the Mothman phenomenon.

A large collection of first-hand material about the Mothman is found in John Keel's 1975 book The Mothman Prophecies, in which Keel lays out the chronology of the Mothman and what he claims to be related parapsychological events in the area, including UFO activity, Men in Black encounters, poltergeist activity, Bigfoot and black panther sightings, animal and human mutilations, precognitions by witnesses, and the December 15, 1967 collapse of the Silver Bridge spanning the Ohio River.

Keel's first book was the basis of a 2002 film, The Mothman Prophecies, starring Richard Gere, Laura Linney, Debra Messing and Will Patton, directed by Mark Pellington. A companion book called the The Eighth Tower, also released in 1975, was derived from material edited from The Mothman Prophecies by the publishers.

In conjunction with Sony/Screen Gems, cryptozoologist Loren Coleman claims to have served as one of the movie's publicity spokespersons, discussing his interpretation of the Mothman events in Mothman and Other Curious Encounters. Coleman created and hyped something called the "Mothman Curse", whereby researchers would be targeted for death adding more to the list in April 2007. Coleman's writings claim that early eyewitnesses never described a "moth" but a large bird. However, the only withness to date who still claims this description seems to be Tom Ury. Witnesses such as Faye DeWitt, Marcella Benett, and Linda Scarberry have repeatedly stated on national TV that the Mothman was half human.

Andy Colvin, a photographer and documentary filmmaker who claims to have seen the Mothman, has produced to books and a reality series on Mothman called The Mothman's Photographer, featuring John Keel and almost 50 witnesses. Colvin's sister took a snapshot of him in 1973 that allegedly shows a Garuda in the background. After researching various forms of Buddhism and certain Native tribes, Colvin's series proposes that both the Garuda of the Far East and the Thunderbird of the Native Americans are synonymous with Mothman, and that Mothman may be an archetypal "guardian angel" who exposes criminal activity at pivotal moments by sending visions, dreams and messages to ordinary humans. The Mothman's Photographer presents evidence that Mound, WV, witnesses separately saw the Mothman, aliens, the Dover Demon, the Virgin Mary, plasma figures, "intelligent", globes of light, and the Flatwoods monster in the same location.

One of the early theories is that the Mothman was a misidentified Sandhill Crane, which, in th elate 1960s had been a problem in surrounding regions. Sandhill Cranes can reach a height of 6 feet, achieve wingspans of 10 feet, have the general appearance described, glide for long distances without flapping and have an unusual shriek. Other recent theories suggest the possibility of the Mothman being a barn owl, an albino owl or perhaps a large Snowy Owl (based on artist's impressions of the mysterious, flying animal). Skeptics suggest that the Mothman's glowing eyes are actually red-eye caused from the reflection of light, from flashlights or other light sources that witnesses may have had with them.

The word "Mothman" was an invention by an Ohio newspaper copyeditor, after the first news stories of the "Big Bird" sightings appeared. (Taken from: wikipedia.org)
