How close have we gotten to the Center of the Earth?
The distance to the center of the Earth is 6,371 kilometers (3,958 mi), the crust is 35 kilometers (21 mi) thick, the mantle is 2855km (1774 mi) thick — and get this: the deepest we have ever drilled is the Kola Superdeep Borehole, which is just 12km deep.
How far is the distance to the center of the Earth?
6,371km The distance to the centre of the Earth has been taken as the volumetric mean radius of the Earth: 6,371km. Note that this distance and the depth of geological layers varies across geographical locations. Depths shown are maxima, except where stated.
How deep do you have to drill to reach the center of the Earth?
You'd soon arrive at the inner core, around 5 million meters below the surface. The inner core is one giant sphere of solid iron, so it would definitely be challenging to get through. But if you did find a way, you'd soon hit the halfway point, about 6.4 million meters down, also known as the center of the Earth.
What would happen if you jumped into a hole through the Earth’s center?
Without air, there would be no air resistance. You would therefore accelerate to incredible speeds as you fall, reaching a maximum speed on the order of tens of thousands of kilometers per hour . You reach earth's center in a matter of minutes or hours instead of weeks.
Why we Cannot go to the Centre of the Earth?
We cannot go to the centre of the earth, since the temperature and pressure increase enormously as we go deeper inside the earth.
Is it possible to travel to the center of the Earth?
You can never "get" to the center of the Earth with any machine, because the pressure would be far too great. We can "see" down there indirectly by using the seismic waves from earthquakes that take place on the other side of the world.
Is Journey to the Center of the Earth possible?
No, you can't hike or spelunk or even tunnel down to the center of the Earth, even if movies like The Core or this summer's 3D adventure flick, Journey to the Center of the Earth, suggest otherwise. To find out about our planet's insides, scientists rely on very different tricks. And, apparently, a little luck.
How hot is it 1 mile underground?
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.
What was found in the deepest hole on Earth?
Microscopic plankton fossils were found six kilometres (3.7 mi) below the surface. Another unexpected discovery was a large quantity of hydrogen gas. The drilling mud that flowed out of the hole was described as "boiling" with hydrogen.
Why did Russia stop drilling the Kola Superdeep Borehole?
Drilling was stopped in 1992, when the temperature reached 180C (356F). This was twice what was expected at that depth and drilling deeper was no longer possible. Following the collapse of the Soviet Union there was no money to fund such projects – and three years later the whole facility was closed down.
Why did they stop drilling to the center of the Earth?
In the late 1980s, the German Continental Deep Drilling Program attempted to drill their own borehole. That project ended because of high temperatures, too. At depths of 9 100 metres, they reached temperatures close to 260 degrees Celsius!
Do you think it is possible to travel to the center of the earth?
You can never "get" to the center of the Earth with any machine, because the pressure would be far too great. We can "see" down there indirectly by using the seismic waves from earthquakes that take place on the other side of the world. When there is a large earthquake, it puts a lot of energy into the Earth.
Is it possible to go to the Centre of the earth?
We cannot go to the centre of the earth, since the temperature and pressure increase enormously as we go deeper inside the earth. Also, no technology has been invented yet to travel deep into the earth.
What would happen if we drilled into the Earth’s core?
Without air, there would be no air resistance. You would therefore accelerate to incredible speeds as you fall, reaching a maximum speed on the order of tens of thousands of kilometers per hour . You reach earth's center in a matter of minutes or hours instead of weeks.
Why can’t people go to the center of the Earth?
You can never "get" to the center of the Earth with any machine, because the pressure would be far too great.

When there is a large earthquake, it puts a lot of energy into the Earth.
How deep in the Earth can humans go?
approximately 7.5 miles How Deep is the Deepest Hole Ever Dug? The deepest hole ever dug is the Kolo Superdeep Borehole in Murmansk, Russia. It reaches approximately 7.5 miles below the Earth's surface (or 12,262 meters). But the hole is only nine inches in diameter (that's about 23 centimeters), so it's impossible for anyone to fall into it.
How far can humans go underground?
The deepest point ever reached by man is 35,858 feet below the surface of the ocean, which happens to be as deep as water gets on earth. To go deeper, you'll have to travel to the bottom of the Challenger Deep, a section of the Mariana Trench under the Pacific Ocean 200 miles southwest of Guam.
What is the deepest a human has been underground?
The Kola Superdeep Borehole was just 9 inches in diameter, but at 40,230 feet (12,262 meters) reigns as the deepest hole. It took almost 20 years to reach that 7.5-mile depth—only half the distance or less to the mantle.
Why can’t we dig deeper into the Earth?
As depth increases into the Earth, temperature and pressure rise. Temperatures in the crust increase about 15 °C per kilometer, making it impossible for humans to exist at depths greater than several kilometers, even if it was somehow possible to keep shafts open in spite of the tremendous pressure.
What was found at the bottom of the deepest hole on Earth?
Scientists found microscopic fossils of single-celled organisms at 4.3 miles (7 kilometers) down. And at nearly the same depth, they discovered water. They also found that the temperature at the bottom of the hole reached a blistering 356°F (180°C). Being too hot to continue, drilling officially halted in 1994.
What was found in the Kola Superdeep Borehole?
The Earth has gas. Unexpectedly, helium, hydrogen, nitrogen, and even carbon dioxide (from microbes) were found all along the borehole. There is no basalt under the continent's granite. This was a huge surprise. Seismic suggested that at 9,000 metres the granite would give way to basalt.
What lives in the Centre of the Earth?
Deeper still. Go deeper, and at 1,000 metres you can still find life. Most inhabitants at this level are tiny invertebrates such as white springtails and mites. But there are also larger species such as Geophilus hadesi.
What would happen if you drilled to the Center of the Earth?
Without air, there would be no air resistance. You would therefore accelerate to incredible speeds as you fall, reaching a maximum speed on the order of tens of thousands of kilometers per hour . You reach earth's center in a matter of minutes or hours instead of weeks.
What would happen if we drilled a hole through the Earth?

Will we ever reach the Earth’s core?
Short answer: No. On the large scale you can think of the Earth as a big ball of fluid. Withstanding the pressure of the bottom of the ocean is something that we are barely able to do, and that is only 0.2% of the way to the center of the Earth.
How hot is the Earth’s core?
9,392° Fahrenheit Temperature in the inner core is about 5,200° Celsius (9,392° Fahrenheit). The pressure is nearly 3.6 million atmosphere (atm). The temperature of the inner core is far above the melting point of iron. However, unlike the outer core, the inner core is not liquid or even molten.
Has anyone ever dug into mantle?
No one has ever drilled into the mantle before, but there have been a half dozen serious attempts. Decades ago, the Russians drilled deeper than anyone has ever gone. Their Kola Superdeep Borehole was started in 1970 and still holds the world record for the deepest hole in the ground.
What was the temperature at the bottom of the Kola Superdeep Borehole?
While the temperature gradient conformed to predictions down to a depth of about 10,000 feet, temperatures after this point increased at a higher rate until they reached 180 °C (or 356 °F) at the bottom of the hole. This was a drastic difference from the expected 100 °C (212 °F).
How much gold is in the Earth’s core?
Wood has calculated that 1.6 quadrillion tons of gold must lie in Earth's core. This may sound like a lot, but it is really only a tiny percentage of the core's overall mass—about one part per million. The core holds six times as much platinum, Wood notes, "but people get less excited about that than gold."
How fast would you need to travel to escape Earth’s gravity?
7 miles per second If you want to completely escape Earth's gravity and travel to another moon or planet, though, you need to be going even faster – at a speed of at least 7 miles per second or about 25,000 miles per hour.
