Mysteries of Egypt :- Mummification

Mummification

The earliest ancient Egyptians buried their dead in small pits in the desert. The heat and dryness of the sand dehydrated the bodies quickly, creating lifelike and natural 'mummies'.  
 Later, the ancient Egyptians began burying their dead in coffins to protect them from wild animals in the desert. However, they realised that bodies placed in coffins decayed when they were not exposed to the hot, dry sand of the desert. 

Mummification has been a real Mystery for the whole world, Till date many theories have been regarded for the same. In this blog we will highlight some of the theories.

 
 
An important man has died and his body needs to be prepared for burial.
The process of mummification has two stages. First, the embalming of the body. Then, the wrapping and burial of the body. 


Embalming:-

 
 First, his body is taken to the tent known as 'ibu' or the 'place of purification'. There the embalmers wash his body with good-smelling palm wine and rinse it with water from the Nile. 



One of the embalmer's men makes a cut in the left side of the body and removes many of the internal organs. It is important to remove these because they are the first part of the body to decompose. The liver, lungs, stomach and intestines are washed and packed in natron which will dry them out. The heart is not taken out of the body because it is the centre of intelligence and feeling and the man will need it in the afterlife. A long hook is used to smash the brain and pull it out through the nose. 

The body is now covered and stuffed with natron which will dry it out. All of the fluids, and rags from the embalming process will be saved and buried along with the body.  The body is now covered and stuffed with natron which will dry it out. All of the fluids, and rags from the embalming process will be saved and buried along with the body. The dehydrated internal organs are wrapped in linen and returned to the body. The body is stuffed with dry materials such as sawdust, leaves and linen so that it looks lifelike. Finally the body is covered again with good-smelling oils. It is now ready to be wrapped in linen.


 In the past, when the internal organs were removed from a body they were placed in hollow canopic jars.
Over many years the embalming practices changed and embalmers began returning internal organs to bodies after the organs had been dried in natron. However, solid wood or stone canopic jars were still buried with the mummy to symbolically protect the internal organs.Each jar has its own properties.

Imsety the human-headed god looks after the liver. Hapy the baboon-headed god looks after the lungs. Duamutef the jackal-headed god looks after the stomach.Qebehsenuef the falcon-headed god looks after the intestines. 
 The body has been cleaned, dried and rubbed with good-smelling oils. Now it is ready to be wrapped in linen. 
Wrapping:-
This is the main part of mummification. Wrapping the corpse in the linen to complete its procedure of afterlife.
First the head and neck are wrapped with strips of fine linen. Then the fingers and the toes are individually wrapped
 The arms and legs are wrapped separately. Between the layers of wrapping, the embalmers place amulets to protect the body in its journey through the underworld. 
.
 
The arms and legs are wrapped separately. Between the layers of wrapping, the embalmers place amulets to protect the body in its journey through the underworld.The arms and legs are tied together. A papyrus scroll with spells from the Book of the Dead is placed between the wrapped hands. A cloth is wrapped around the body and a picture of the god Osiris is painted on its surface.
Finally, a large cloth is wrapped around the entire mummy. It is attached with strips of linen that run from the top to the bottom of the mummy, and around its middle.



A board of painted wood is placed on top of the mummy before the mummy is lowered into its coffin. The first coffin is then put inside a second coffin. The funeral is held for the deceased and his family mourns his death. A ritual called the 'Opening of the Mouth' is performed, allowing the deceased to eat and drink again.
Finally, the body and its coffins are placed inside a large stone sarcophagus in the tomb. Furniture, clothing, valuable objects, food and drink are arranged in the tomb for the deceased.
Now his body is ready for its journey through the underworld. There his heart will be judged by his good deeds on earth. If his heart is found to be pure he will be sent to live for all eternity in the beautiful 'Field of Reeds'. 

In Next Post we will inspect the Coffin with scientific methods. Till then Mystery Continues...

Time Travel:- Is it Real? Believe it orNot

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

Imagine You are having the watch which can let you travel through time in Past or in Future any time. You can Go 8 years forward to take your matured Fixed Deposit in Bank. Also You can live your most happy moments again and again . Wow it is So Fun! This Post is about the same keep reading Pal's.


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.

Bermuda triangle

Bermuda Triangle:- Unknown Mystery



The Bermuda Triangle, also known as the Devil's Triangle, is a loosely defined region in the western part of the North Atlantic Ocean, where a number of aircraft and ships are said to have disappeared under mysterious circumstances. According to the US Navy, the triangle does not exist, and the name is not recognized by the US Board on Geographic Names.Popular culture has attributed various disappearances to the paranormal or activity by extraterrestrial beings. Documented evidence indicates that a significant percentage of the incidents were spurious, inaccurately reported, or embellished by later authors. In a 2013 study, the World Wide Fund for Nature identified the world’s 10 most dangerous waters for shipping, but the Bermuda Triangle was not among them.

The Bermuda Triangle is a large area of ocean between Florida, Puerto Rico, and Bermuda.
The Bermuda Triangle’s bad reputation started with Christopher Columbus. According to his log, on October 8, 1492, Columbus looked down at his compass and noticed that it was giving weird readings. He didn’t alert his crew at first, because having a compass that didn’t point to magnetic north may have sent the already on edge crew into a panic. This was probably a good decision considering three days later when Columbus simply spotted a strange light, the crew threatened to return to Spain.
This and other reported compass issues in the region gave rise to the myth that compasses will all be off in the Triangle, which isn’t correct, or at least is an exaggeration of what is actually happening as you’ll see.  Despite this, in 1970 the U.S. Coast Guard, attempting to explain the reasons for disappearances in the Triangle, stated:
First, the “Devil’s Triangle” is one of the two places on earth that a magnetic compass does point towards true north. Normally it points toward magnetic north. The difference between the two is known as compass variation. The amount of variation changes by as much as 20 degrees as one circumnavigates the earth. If this compass variation or error is not compensated for, a navigator could find himself far off course and in deep trouble.
