Speed of the light !!



|Speed of Light in Gravity|

An observer outside gravitational fields measures the speed of light locally (in his location) at 299792.458 km/s but when he looks towards a black hole he sees the speed of light there to be as slow as a few meters/s. At the same time an observer freefalling into that black hole measures the speed of light locally (in his location) at 299792.458 km/s; when he looks towards the black hole he sees the speed of light there much slower; when he looks away from the black hole he sees the speed of light there much faster. When he looks towards outside gravitational fields he sees the speed of light there a zillion km/s. In 1915 (10 years after Special Relativity) Einstein developed another theory called General Relativity where gravity causes the speed of light to become relative

|Cosmological Speed of Light|

Astronomers just confirmed the existence of "Dark Energy", a mysterious repulsive force that acts in opposite to gravity. This "Dark Energy" is causing the entire universe to expand at an increasing rate. This Dark Energy is even causing distant galaxies to recede from us faster than our local speed of light. Scientists today do not know what this "Dark Energy" is but they know that it is dragging inertial frames apart. This means that light en route is being dragged away from us. This makes observers to see distant inbound light at effective speeds less than 299792.458 km/s and to see distant outbound light at effective speeds greater than 299792.458 km/s. However every inertial observer measures the speed of light locally (in his location) at 299792.458 km/s in any direction.

|12000 Lunar Orbits/Earth Day|

The measured speed of light in local inertial frames is 299792.458 km/sec. So if you want to make a comparison with "299792.458 km/sec" then you have to make it in a "local inertial frame". When we compare the nominal speed of light with 12000 Lunar Orbits / Earth Day inside the gravitational field of the sun (non-inertial frame) we get 11% difference; however when we compare them outside the gravitational field of the sun (inertial frame) we get zero% difference: The distance to the sun is not a constant, so as the distance to the sun increases the difference in energy causes the length of the lunar orbit to change. When the Earth-moon system exits the solar system the geocentric frame travels in a straight line (becomes inertial) and 12000 Lunar Orbits / Earth Day becomes equivalent to the speed of light.


Laughter is the Best Medicine!!

|THE HEALTH BENEFITS OF HUMOR AND LAUGHTER|

Humor is infectious. The sound of roaring laughter is far more contagious than any cough, sniffle, or sneeze. When laughter is shared, it binds people together and increases happiness and intimacy. Laughter also triggers healthy physical changes in the body. Humor and laughter strengthen your immune system, boost your energy, diminish pain, and protect you from the damaging effects of stress. Best of all, this priceless medicine is fun, free, and easy to use..!!

Laughter is strong medicine for mind and body
Laughter is a powerful antidote to stress, pain, and conflict. Nothing works faster or more dependably to bring your mind and body back into balance than a good laugh. Humor lightens your burdens, inspires hopes, connects you to others, and keeps you grounded, focused, and alert.
With so much power to heal and renew, the ability to laugh easily and frequently is a tremendous resource for surmounting problems, enhancing your relationships, and supporting both physical and emotional health.
Laughter is good for your health
Laughter relaxes the whole body. A good, hearty laugh relieves physical tension and stress, leaving your muscles relaxed for up to 45 minutes after.
Laughter boosts the immune system. Laughter decreases stress hormones and increases immune cells and infection-fighting antibodies, thus improving your resistance to disease.
Laughter triggers the release of endorphins, the body’s natural feel-good chemicals. Endorphins promote an overall sense of well-being and can even temporarily relieve pain.

Laughter protects the heart. Laughter improves the function of blood vessels and increases blood flow, which can help protect you against a heart attack and other cardiovascular problems. 

Ancient language discovered on clay tablets found amid ruins of 2800 year old Middle Eastern palace


Archaeologists have discovered evidence for a previously unknown ancient language – buried in the ruins of a 2800 year old Middle Eastern palace.

The discovery is important because it may help reveal the ethnic and cultural origins of some of history’s first ‘barbarians’ – mountain tribes which had, in previous millennia, preyed on the world’s first great civilizations,  the cultures of early Mesopotamia in what is now Iraq.
Evidence of the long-lost language - probably spoken by a hitherto unknown people from the Zagros Mountains of western Iran – was found by a Cambridge University archaeologist as he deciphered an ancient clay writing tablet unearthed by an international archaeological team excavating an Assyrian imperial governors’ palace in the ancient city of Tushan, south-east Turkey.
The tablet revealed the names of  60 women – probably prisoners-of-war  or victims of an Assyrian forced population transfer programme. But when the Cambridge archaeologist – Dr. John MacGinnis - began to examine the names in detail, he realized that 45 of them bore no resemblance to any of the thousands of ancient Middle Eastern names already known to scholars.
Because ancient Middle Eastern names are normally composites, made-up, in full or abbreviated form, of ordinary words in the relevant local lexicon, the unique nature of the tablet’s 45 mystery names is seen by scholars as evidence of a previously unknown language.
The clay tablet text originally formed part of the palace’s archive – used by local  Assyrian imperial officials to record their administrative, political and economic decisions and actions.
The 60 women (including the 45 with evidence of the previously unattested language) were almost certainly being deployed by the palace authorities for some economic purpose (potentially a female-associated craft activity like weaving). Indeed the text mentions that some of them were being allocated to specific local villages.
Typical names, borne by the women – the evidence for the lost language – include Ushimanay, Alagahnia, Irsakinna and Bisoonoomay.
Now archaeologists and linguistics experts are set to analyse the mystery names in even greater details to try to discover whether the letter-order or letter frequency shows any similarities to previously attested ancient tongues to which this mystery language could be related.
The 45 women are thought to come from somewhere in the central or northern Zagros Mountains – because that is the only area in which the Assyrians were militarily active at the relevant time where the ancient languages are still largely unknown.
It’s likely that the women were compulsorily moved from their Zagros Mountains homeland and assigned to work near Tushan sometime in the second half of the 8th century BC – probably as a result of conquests carried out in the Zagros by the Assyrian kings Tiglath Pilasser III or Sargon.

The excavation of the palace at Tushan is being carried out by a German archaeological team directed by Dr. Dirk Wicke of Mainz University as part of an archaeological investigation into the ancient Assyrian city led by Professor Timothy Matney of the University of Akron in Ohio. Full details about the discovery of the mystery names are published in the current issue of the Journal of Near Eastern Studies. !!

Clothing in the ancient world !!

The clothing used in the ancient world strongly reflects the technologies that these peoples mastered. Archaeology plays a significant role in documenting this aspect of ancient life, for fabric fibres, and leathers sometimes are well-preserved through time. In many cultures the clothing worn was indicative of the social status achieved by various members of their society

Ancient Egyptian clothing

In Ancient Egypt, flax was the textile in almost exclusive use. Wool was known, but considered impure as animal fibres were considered taboo, and could only be used for coats (they were forbidden in temples and sanctuaries). People of lower class wore only the loincloth (or schenti) that was common to all. Shoes were the same for both sexes; sandals braided with leather, or, particularly for the bureaucratic and priestly classes, papyrus. The most common headgear was the klafta, striped fabric square worn by men. Feather headdresses were worn by nobility.

Certain clothing was common to both genders such as the tunic and the robe. Around 1425 to 1405 BCE, a light tunic or short-sleeved shirt was popular, as well as a pleated skirt.

Clothing for adult women remained unchanged over several millennia, save for small details. Draped clothes, with very large rolls, gave the impression of wearing several items. It was in fact a haïk, often of very fine muslin[dubious – discuss]. The dress was rather narrow, even constricting, made of white or unbleached fabric for the lower classes, the sleeve starting under the chest in higher classes, and held up by suspenders tied onto the shoulders. These suspenders sometimes were wide enough to cover the breasts and were painted and colored for various reasons, for instance to imitate the plumage on the wings of Isis.

Clothing of the royal family was different, and was well documented; for instance the crowns of the pharaohs (see links below), the nemes head dress, and the khat or head cloth worn by nobility.

The most expensive dog !!


The most expensive dog ever sold!!

The most expensive dog ever sold was recently in March 2011, a red “Tibetan mastiff” called Big Splash, or “Hong Dong” in Chinese.  This most expensive dog ever is already 11 months-old and already stands nearly three-feet-high at the shoulder and weighs more than 180lbs, says his breeder, Lu Liang.   He was purchased by a chinese multi-millionaire coal baron.


‘Big Splash’ sold for an amazing 10 million Yuan which is about 1.5 million US Dollars and beats the earlier record set by another Tibetan Mastiff Tibetan mastiff” called Yangtze River Number Two which was sold to a chinese woman in 2009 for a whopping 4 million Yuan (About $609,000).   But this still doesn’t make the Tibetan Mastiff generally the most expensive dog breed !!

The most expensive shoe !!
