Time Travel:- Is it Real? Believe it or Not

Time travel is the concept of movement (often by a human) between different points in time in a manner analogous to moving between different points in space, typically using a hypothetical device known as a time machine. Time travel is a recognized concept in philosophy and fiction, but travel to an arbitrary point in time has a very limited support in theoretical physics, usually only in conjunction with quantum mechanics or Einstein–Rosen bridges. Sometimes the above narrow meaning of time travel is used, sometimes a broader meaning. For example, travel into the future (not the past) via time dilation is a well-proven phenomenon in physics (relativity) and is routinely experienced by astronauts, but only by several milliseconds, as they can verify by checking a precise watch against a clock that remained on Earth. Time dilation by years into the future could be done by taking a round trip during which you move at speeds approaching that of light, but this is not currently technologically feasible for manned vehicles.

The concept is popular in science fiction novels; a science fiction novel written in 1895 called The Time Machine, by H. G. Wells, was instrumental in moving the concept of time travel to the forefront of the public imagination, but the earlier short story "The Clock That Went Backward", by Edward Page Mitchell, involves a clock that, by means unspecified, allows three men to travel backward in time. Non-technological forms of time travel had appeared in a number of earlier stories such as Charles Dickens' A Christmas Carol. Historically, the concept dates back to the early mythologies of Hinduism (such as the Mahabharata). More recently, with advancing technology and a greater scientific understanding of the universe, the plausibility of time travel has been explored in greater detail by science fiction writers, philosophers, and physicists.

Theory used for Time Travel

 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 were 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 time like curves, which are world lines 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 space times which contain closed time like curves (such as Gödel spacetime), but the physical plausibility of these solutions is uncertain.

Relativity predicts that if one were to move away from the Earth at relativistic velocities and return, more time would have passed on Earth than for the traveler, so in this sense it is accepted that relativity allows "travel into the future" (according to relativity there is no single objective answer to how much time has really passed between the departure and the return, but there is an objective answer to how much proper time has been experienced by both the Earth and the traveler, i.e., how much each has aged; see twin paradox). On the other hand, many in the scientific community believe that backward time travel is highly unlikely. Any theory that would allow time travel would introduce potential problems of causality. The classic example of a problem involving causality is the "grandfather paradox": what if one were to go back in time and kill one's own grandfather before one's father was conceived? But some scientists believe that paradoxes can be avoided, by appealing either to the Novikov self-consistency principle or to the notion of branching parallel universes.

Time travel or spacetime travel

An objection that is sometimes raised against the concept of time machines in science fiction is that they ignore the motion of the Earth between the date the time machine departs and the date it returns. The idea that a traveler can go into a machine that sends him or her to 1865 and step out into exactly the same spot on Earth might be said to ignore the issue that Earth is moving through space around the Sun, which is moving in the galaxy, and so on, so that advocates of this argument imagine that "realistically" the time machine should actually reappear in space far away from the Earth's position at that date. However, the theory of relativity rejects the idea of absolute time and space; in relativity there can be no universal truth about the spatial distance between events which occur at different times (such as an event on Earth today and an event on Earth in 1865), and thus no objective truth about which point in space at one time is at the "same position" that the Earth was at another time. In the theory of special relativity, which deals with situations where gravity is negligible, the laws of physics work the same way in every inertial frame of reference and therefore no frame's perspective is physically better than any other frame's, and different frames disagree about whether two events at different times happened at the "same position" or "different positions". In the theory of general relativity, which incorporates the effects of gravity, all coordinate systems are on equal footing because of a feature known as "diffeomorphism invariance".

Bermuda Triangle:-Science or Myth

Bermuda Triangle:-Science or Myth

In last Post we understood what is Bermuda Triangle and where is it, But in this post we will try to learn some Scientific explanations for this.

Of course, despite this now being repeated as an explanation for disappearances in the Triangle on numerous documentaries and articles since then, it turns out magnetic variation is something ship captains (and other explorers) have known about and had to deal with pretty much as long as there have been ships and compasses. Dealing with magnetic declination is really just “Navigation by Compass” 101 and nothing to be concerned about, nor anything that would seriously throw off any experienced navigator.
In 2005, the Coast Guard revisited the issue after a TV producer in London inquired about it for a program he was working on.  In this case, they correctly changed their tune about the magnetic field bit stating,

Many explanations have cited unusual magnetic properties within the boundaries of the Triangle. Although the world’s magnetic fields are in constant flux, the “Bermuda Triangle” has remained relatively undisturbed.  It is true that some exceptional magnetic values have been reported within the Triangle, but none to make the Triangle more unusual than any other place on Earth.

The modern Bermuda Triangle legend didn’t get started until 1950 when an article written by Edward Van Winkle Jones was published by the Associated Press. Jones reported several incidences of disappearing ships and planes in the Bermuda Triangle, including five US Navy torpedo bombers that vanished on December 5, 1945, and the commercial airliners “Star Tiger” and “Star Ariel” which disappeared on January 30, 1948 and January 17, 1949 respectively. All told, about 135 individuals were unaccounted for, and they all went missing around the Bermuda Triangle. As Jones said, “they were swallowed without a trace.”
It was a 1955 book, The Case for the UFO, by M. K. Jessup that started pointing fingers at alien life forms. After all, no bodies or wreckage had yet been discovered. By 1964, Vincent H. Gaddis—who coined the term “Bermuda Triangle”—wrote an article saying over 1000 lives had been claimed by the area. He also agreed that it was a “pattern of strange events.” The Bermuda Triangle obsession hit its peak in the early 1970s with the publication of several paperback books about the topic, including the bestseller by Charles Berlitz, The Bermuda Triangle.
However, critic Larry Kusche, who published The Bermuda Triangle Mystery: Solved in 1975, argued that other authors had exaggerated their numbers and hadn’t done any proper research. They presented some disappearance cases as “mysteries” when they weren’t mysteries at all, and some reported cases hadn’t even happened within the Bermuda Triangle.

After extensively researching the issue, Kusche concluded that the number of disappearances that occurred within the Bermuda Triangle wasn’t actually greater than in any other similarly trafficked area of the ocean, and that other writers presented misinformation—such as not reporting storms that occurred on the same day as disappearances, and sometimes even making it seem as though the conditions had been calm for the purposes of creating a sensational story. In short: previous Bermuda Triangle authors didn’t do their research and either knowingly or unintentionally “made it up.”
The book did such a thorough job of debunking the myth that it effectively ended most of the Bermuda Triangle hype. When authors like Berlitz and others were unable to refute Kusche’s findings, even the most steadfast of believers had difficulty remaining confident in the sensationalized Bermuda Triangle narrative. Nevertheless, many magazine articles, TV shows, and movies have continued to feature the Bermuda Triangle.
Because the number of disappearances in the Bermuda Triangle is no greater than any other similarly trafficked area of the world’s oceans, they don’t really need an explanation. But if you’re still convinced that the Triangle is a ship graveyard, relative to other regions that get around the same number of travelers, here are some natural explanations from the Coast Guard to combat some of the “alien” and other fantastical theories.

The majority of disappearances can be attributed to the area’s unique features. The Gulf Stream, a warm ocean current flowing from the Gulf of Mexico around the Florida Straits northeastward toward Europe, is extremely swift and turbulent. It can quickly erase any evidence of a disaster.
The unpredictable Caribbean-Atlantic storms that give birth to waves of great size as well as waterspouts often spell disaster for pilots and mariners. (Not to mention that the area is in “hurricane alley.”) The topography of the ocean floor varies from extensive shoals to some of the deepest marine trenches in the world. With the interaction of strong currents over reefs, the topography is in a constant state of flux and breeds development of new navigational hazards.
Not to be underestimated is the human factor. A large number of pleasure boats travel the water between Florida’s Gold Coast (the most densely populated area in the world) and the Bahamas. All to often, crossings are attempted with too small a boat, insufficient knowledge of the area’s hazards and lack of good seamanship.

Mermaids

Real Mermaid Found Dead :- Real Pictures No Fake

Mermaid found at Porbandar and Karachi beach, oh really?

For those of you who grew up following the conventional wisdom of ‘you believe only when you see’, these images could be startling! In today’s day and age when computer imagery and special effects are employed to make any visual jazzy, and exciting, if you believe only because you see, and then spread the information, you could possibly lead to more confusion and chaos.

These pictures, supposedly of a mermaid (or Jalpari), apparently found in Karachi, Pakistan, and subsequently spotted in Porbander, Gujarat, has caught many eyeballs in the internet space. Here’s she, the angelic Ariel, the in-flesh version of the cutesy mermaid of Disney’s The Little Mermaid series. But is she for real? Or are these some leaked out pictures straight from the sets of a Hollywood movie? Or is this just a prank to elicit ‘look- how-I-made-em-fools’ reactions? We, for sure, have no clue!
What we do know, for sure, is that while Miss M’s fin and her axial appendages may make the visual look real, her sharp facial features, her carved lips and high cheekbones make her the glamorous beauty of the underwater world. “Oh, she must be the sexiest mermaid around,” squealed someone. Maybe the ‘mermaid’ has just taken a leap of faith, after realising her rare beauty, landed on our shores, perhaps to participate in our de rigueur beauty pageants!
PS: Though Miss M’s shiny diving suit looks pretty impressive, we wonder where her oxygen mask is.

Mermaids

Mermaids:- Real or Imagination

A mermaid is a legendary aquatic creature with the upper body of a female human and the tail of a fish. Mermaids appear in the folklore of many cultures worldwide, including the Near East, Europe, Africa and Asia. The first stories appeared in ancient Assyria, in which the goddess A targatis transformed herself into a mermaid out of shame for accidentally killing her human lover. Mermaids are sometimes associated with perilous events such as floods, storms, shipwrecks and drownings. In other folk traditions (or sometimes within the same tradition), they can be benevolent or beneficent, bestowing boons or falling in love with humans.
Mermaids are associated with the mythological Greek sirens as well as with sirenia, a biological order comprising dugongs and manatees. Some of the historical sightings by sailors may have been misunderstood encounters with these aquatic mammals. Christopher Columbus reported seeing mermaids while exploring the Caribbean, and supposed sightings have been reported in the 20th and 21st centuries in Canada, Israel, and Zimbabwe.

In mythology, mermaids — or mermaid like creatures — have existed for thousands of years.
The first myths of mermaids may have originated around 1000 B.C. — stories tell the tale of a Syrian goddess who jumped into a lake to turn into a fish, but her great beauty could not be changed and only her bottom half transformed.
Since then, many other mermaid stories have appeared in folklore from various cultures around the world. For instance, the African water spirit Mami Wata is mermaid in form, as is the water spirit Lasirn, who is popular in folklore in the Caribbean Islands.
Throughout history, various explorers have reported sightings of mermaids, the most famous of which was Christopher Columbus.

Columbus claimed to have spotted mermaids near Haiti in 1493, which he described as being "not as pretty as they are depicted, for somehow in the face they look like men," according to the American Museum of Natural History.

Captain John Smith is described in Edward Rowe Snow's "Incredible Mysteries and Legends of the Sea" (Dodd Mead, January 1967) as seeing a big-eyed, green-haired mermaid in 1614 off the coast of Newfoundland; apparently Smith felt "love" for her until he realized she was a fish from the waist down.

Experts believe Columbus, Smith and other mermaid-spotting explorers really caught glimpses of human-sized marine mammals called manatees and dugongs.
Indeed, despite past and recent "sightings" of the mythical sea creatures, mermaids, like the Lock Ness Monster, may just be a case of mistaken identity.

With nearly three-quarters of the Earth covered by water, it's little wonder that, centuries ago, the oceans were believed to contain many mysterious creatures, including sea serpents and mermaids. Merfolk (mermaids and mermen) are, of course, only the marine version of half-human, half-animal legends that have captured human imagination for ages.C.J.S. Thompson, a former curator at the Royal College of Surgeons of England, noted in his book "The Mystery and Lore of Monsters" (Kessinger, 2010), "Traditions concerning creatures half-human and half-fish in form have existed for thousands of years, and the Babylonian deity Era or Oannes, the Fish-god, is represented on seals and in sculpture, as being in this shape over 2,000 years B.C. He is usually depicted as having a bearded head with a crown and a body like a man, but from the waist downwards, he has the shape of a fish covered with scales and a tail."

Greek mythology contains stories of the god Triton, the merman messenger of the sea, and several modern religions, including Hinduism and Candomblé (an Afro-Brazilian belief), worship mermaid goddesses to this day. In folklore, mermaids were often associated with bad luck and misfortune. They lured errant sailors off course and even onto rocky shoals, much like their cousins, the sirens  — beautiful, alluring half-bird, half-women who dwelled near rocky cliffs and sung to passing sailors. The sirens would enchant men to steer their ships toward the singing — and the dangerous rocks that were sure to sink them. Homer's "Odyssey," written around 800 B.C., tells tales of the brave Ulysses, whose naked ears were tortured by the sweet sounds of the sirens. In other legends — from Scotland and Wales, for example — mermaids befriended, and even married, humans.

Scientific Proof

In 1997, the Bloop was heard on hydrophones across the Pacific. It was a loud, ultra-low frequency sound that was heard at listening stations underwater over 5,000km apart, and one of many mysterious noises picked up by the National Oceanic and Atmospheric Administration (NOAA). Several articles in the years that followed popularised one suggestion that the Bloop might have been the sound of an unknown animal due to the "organic" nature of the noise, a theory that elevated the Bloop to the level of a great unsolved mystery.

 However, the NOAA is pretty sure that it wasn't an animal, but the sound of a relatively common event -- the cracking of an ice shelf as it breaks up from Antarctica. Several people have linked to the NOAA's website over the past week excitedly claiming that the mystery of the Bloop has been "solved", but as the information on the NOAA website was undated and without a source, Wired.co.uk spoke to NOAA and Oregon State University seismologist Robert Dziak by email to check it out. He confirmed that the Bloop really was just an icequake -- and it turns out that's kind of what they always thought it was. The theory of a giant animal making noises loud enough to be heard across the Pacific was more fantasy than science.

In Next Blog will show some real proofs to explain this mystery more deeply.
