Buried deep under a hill in central China, surrounded by an underground moat of poisonous mercury, lies an entombed emperor who's been undisturbed for more than two millennia.

The tomb holds the secrets of China's first emperor, Qin Shi Huang, who died on Sept. 10, 210 B.C., after conquering six warring states to create the first unified nation of China.

The answers to a number of historical mysteries may lie buried inside that tomb, but whether modern people will ever see inside this mausoleum depends not just on the Chinese government, but on science.

"The big hill, where the emperor is buried - nobody's been in there," said archaeologist Kristin Romey, curatorial consultant for the Terracotta Warrior exhibition at New York City's Discovery Times Square. "Partly it's out of respect for the elders, but they also realize that nobody in the world right now has the technology to properly go in and excavate it."

The warring states

Qin Shi Huang (pronounced "chin shuh hwang") was born in 259 B.C., first son to the king of Qin, one of six independent kingdoms inside modern China. These kingdoms had been warring for more than 200 years, but through a combination of military strength, strategy and natural disasters, Qin Shi Huang conquered them all, proclaiming himself not just a king, but also an emperor - the first of China.

Scholars still debate the details of how this occurred, and what unique tactics allowed the Qin emperor to achieve what no one had managed before.

When he died, Qin Shi Huang was buried in the most opulent tomb complex ever constructed in China, a sprawling, city-size collection of underground caverns containing everything the emperor would need for the afterlife. The ancient Chinese, along with many cultures including ancient Egyptians, believed that items and even people buried with a person could be taken with him to the afterlife.

But instead of burying his armies, concubines, administrators and servants with him, the Qin emperor came up with an alternative: clay reproductions.

Shocking discovery

In 1974, a group of farmers digging wells near Xi'an, China stumbled upon one of the most shocking archaeological discoveries of all time. The life-size terracotta solider they dug out of the ground turned out to be just one of an army of thousands, each utterly unique, with individual clothing, hair and facial features.

For almost four decades, archaeologists have been excavating the site. So far, they've uncovered about 2,000 clay soldiers, but experts estimate there are more than 8,000 in total.

"They're going to be digging there for centuries," Romey predicted.

Still, scientists have yet to touch the central tomb, which holds a palace containing the body of Qin Shi Huang.

"It's really smart what the Chinese government is doing," Romey told LiveScience. "When we went into [Egyptian King] Tut's tomb, think about all the information we lost just based on the excavation techniques of the 1930s. There's so much additional that we could have learned, but the techniques back then weren't what we have now."

"Even though we may think we have great archaeological excavation techniques right now," she said, "who knows, a century down the road if we open this tomb, what they're going to say?"

Even though they number in the thousands, each terracotta soldier has painstakingly detailed armor, facial features, hair and clothing.

To open the tomb?

The decision whether to explore the tomb anytime soon, or ever, is up to the government of China. That decision will likely be influenced by the pace of technological progress.

"In archaeological conservation, every year you have major new developments," Romey said. "When we began excavating [the soldiers] in the '70s, the minute they were exposed to air and sunlight, the pigment just flaked off. Now they've figured out a new technique where they can actually preserve the paint as they excavate."

Perhaps, if science advances enough, that excavation wouldn't cause serious damage to the burial site, and the tomb will finally be opened. [ Album: The Seven Ancient Wonders of the World]

"I wouldn't be surprised if you had some sort of robotic visual survey going in there at some point," Romey said.

And despite their desire to protect the treasures of antiquity, archaeologists are itching with curiosity to find out what's inside Qin Shi Huang's central tomb.

Rivers of mercury

Ancient writings say the emperor created an entire underground kingdom and palace, complete with a ceiling mimicking the night sky, set with pearls as stars. Pits full of terracotta concubines have never been discovered, though experts predict they exist somewhere in the complex.

And Qin Shi Huang's tomb is also thought to be encircled with rivers of liquid mercury, which the ancient Chinese believed could bestow immortality.

"It's kind of ironic," Romey said. "This is probably how he died, by ingesting mercury. He was taking all these mercury pills because he wanted to live forever and it killed him by the age of 39."

That moat of mercury also presents another reason why archaeologists are loath to explore the tomb just yet - doing so would likely be very dangerous, according to soil samples around the tomb, which indicate extremely high levels of mercury contamination.

In the end, scientists and historians must always weigh their desire to know more with the damage such inquiry would cause.

"Archaeology, ultimately, is a destructive science," Romey said. "You have to destroy stuff in order to learn about it."
