DNA bolsters Bulgaria's John the Baptist bones claim

{Re-Post from Yahoo News}

DNA bolsters Bulgaria's John the Baptist bones claim

The remains, which include a molar and a piece of cranium, were found in July 2010 in a marble sarcophagus in the ruins of a medieval church on the island of Sveti Ivan, or Saint John, off Bulgaria's Black Sea coast near the resort of Sozopol.

They are on display in a church in Sozopol where thousands of worshippers have flocked to view them, untroubled by questions about their authenticity.

"When I first heard this story in 2010 I thought it was a bit of a joke, to be honest," said Tom Higham of the University of Oxford's Radiocarbon Accelerator Unit, one of the world's top laboratories for carbon dating of archaeological material.

Higham's team dated a knuckle-bone to the first century AD, when John the Baptist would have lived, while geneticist colleagues from the University of Copenhagen established the full DNA code of three of the bones.

The genetic analysis showed that the bones were from the same person, a man who most probably came from the Middle East.

Higham, who is an atheist, said that it was obviously impossible to say with any certainty that the remains belonged to John the Baptist. But it could not be ruled out.

"I'm much less skeptical than I was at the beginning. I think there's possibly more to it. But I'd like to find out more," he told Reuters on Friday.

12 HANDS AND SIX HEADS

Relics of saints or fragments of the True Cross on which Jesus was crucified, according to Christian tradition, have been a powerful draw for pilgrims and tourists for centuries. Thousands of such relics can be found in churches across Europe.

But skeptics have always dismissed these items as a scam to lure the credulous, and some joke that if all the bones said to have belonged to John the Baptist were authentic the Biblical figure would have had 12 hands and six heads.

Higham plans to apply for funding to analyze purported John the Baptist relics from other places to see if any of them came from the same individual whose remains were found on Sveti Ivan.

"I look at this as a bit of fun. I'm not a hard core ecclesiastical researcher. I actually study Neanderthals and stuff like that, older stuff," said Higham.

"But I'm really interested in applying radio carbon dating more widely to find out information about the past."

John the Baptist, who is revered in Christianity and Islam, announced the coming of Jesus and baptized him in the River Jordan. The Gospels say King Herod had him beheaded.

Oxford archaeologist Georges Kazan, who wrote his doctoral thesis on the movement of relics in the 5th and 6th centuries, said that there was historical evidence to support the claim that the Sveti Ivan remains could be authentic.

The evidence includes a small box made from volcanic tuff, or consolidated ash, which was found next to the bones and is inscribed with John's name and his feast day in Ancient Greek.

The tuff came from Cappadocia, in modern Turkey, which was one of the routes used to take purported relics from the Holy Land to Constantinople, now Istanbul, where in the 5th and 6th centuries Eastern Roman Emperors were keen to acquire them.

The emperors, who were copied by pious aristocrats, wanted relics for devotional purposes or to be buried with them.

"They were often bestowed as a sign of favor. The monastery of Sveti Ivan may well have received a portion of relics as a gift from a patron, a member of Constantinople's elite," said Kazan, adding that the island was an easy distance from the Byzantine capital on a major Black Sea trading route.

CERN claims faster-than-light particle measured

CERN claims faster-than-light particle measured | WBRZ News 2 Louisiana : Baton Rouge, LA |

 

GENEVA - Scientists at the world's largest physics lab say they have clocked subatomic particles traveling faster than light.

If that's true, it would break - if not severely twist - a fundamental pillar of physics.

Nothing is supposed to go faster than light.

But scientists say that neutrinos - one of the strangest well-known particles in physics - smashed past the cosmic speed barrier of 186,282 miles per second.

The European Organization for Nuclear Research, CERN, says the speeds were detected in a neutrino beam fired from Geneva to a lab 454 miles away in Italy.

Baffled scientists are asking others to independently verify the measurements or find other more mundane explanations for the measured speed.


I personally cannot imagine how fast this is.  When you start breaking this down into 'real' time it looks something like this:

186,282mps = time a neutrinos travels in a second

186,282mps X 60 seconds = 11,176,920mpminute

11,176,920mpm X 60 minutes = 670,615,200mphour

670,615,200mph X 24hours = 16,094,764,800mpday

16,094,764,800mpd X 365days = 5,874,589,152,000mpyear

THE SPEED OF LIGHT

 In our every day lives light seems to travel from one place to another instantaneously. When we flip on the light in a room there is no delay between when we first see the bulb start glowing and when light illuminates the far corners of the chamber. Our nervous systems are much too slow to notice the rays of light that appear from the bulb and move like a wave washing over the room. 

Light travels at a speed of 186,000 miles a second or 700 million miles an hour. For scale, the distance from the Earth to the Moon is about 239,000 miles. This seems pretty fast and indeed theory says that nothing can travel faster than the speed of light, (until today, 9-23-2011 {emphasis mine}).

When we deal with the immense distances of space, though, even light seems slow. When astronauts were on the Moon it took over a second for the radio waves (which travel at the speed of light) carrying their voices to reach us. Light coming from the sun takes eight and one half minutes to hit Earth. (This means that if the sun were suddenly to go dark, it would take over eight minute for us to notice) Light from the nearest stars, other than the sun, takes four and a half years to get here. From the farthest stars in distant galaxies it can take billions of years for the light to arrive..

The distance light can travel in a year is called a "light year." The light year is one of the basic measures of distance for astronomy.

Here's a picture that gives some idea of how LIGHT travels, in regards to time, from various points in out Solar System:
