Diamond History The earliest diamonds were found in India in 4th century BC, although the youngest of these deposits were formed 900 million years ago. A majority of these early stones were transported along the network of trade routes that connected India and China, commonly known as the Silk Road.

About The Big Hole Digging commenced at the Kimberley mine site in 1871. After a further two diamonds were found in the area, a diamond rush ensued and miners arrived in their thousands. The hill disappeared in a flurry of prospection, as picks and shovels yielded 2 722 kilograms of diamonds.

The earliest recorded cultures used diamonds to portray strength, the value of love, and even instruments of magic. That value is likely due to a diamond’s natural strength and unique visual appearance in combination with its relative rarity. Even a low-grade gem-quality diamond is still a thing of value and beauty.

A 100-year-old copper mine in the mountains near Salt Lake City, Utah hosts a pit that extends three quarters of a mile deep and spans 2.5 miles. At 215 meters, the Kimberley Diamond Mine in South Africa is one of the largest holes in the world dug by human hands. We also dig, of course, for science.

Kola Superdeep Borehole SG-3

Deepest drillings The Kola Superdeep Borehole on the Kola peninsula of Russia reached 12,262 metres (40,230 ft) and is the deepest penetration of the Earth’s solid surface. The German Continental Deep Drilling Program at 9.1 kilometres (5.7 mi) has shown the earth crust to be mostly porous.

Geologists calculate that, for every mile you dig beneath the Earth’s surface, the temperature rises 15º F and the pressure increases simultaneously at a rate of about 7,300 pounds per square inch. Violations of the 15-degrees-per-mile rule are unknown and constitute the notorious forbidden zone.

To dig to China, you’d need to start your journey from Chile or Argentina — the location of China’s antipode (or opposite point on Earth). You would need a super-powered drill to get through rock and metal within Earth’s three layers. First, there’s the Earth’s crust.

It is used when a hole is so deep that it is (humorously) supposed to be going to go right through the earth and come out the other side. …

This is all because Earth is a sphere, of course, meaning that if you dig straight down in the northern hemisphere you’ll end up just as far from the equator in the southern hemisphere.

You would just float, being pulled equally by gravity in all directions. That said, you would still be traveling at an unparalleled speed, so you’d zip right through that awesome feeling pretty quickly. As you pass through Earth’s center, still moving at 6 miles per second, the process would begin to reverse.

The question we had was, what would happen if you dug a hole all the way through the earth(from one side to the other, right through the middle) and dropped an object into the hole? The answer is as follows. So the stone would keep on moving, going straight on up the other side of the hole, towards China.
