How many miles is it straight through the center of the Earth?
The simple quick answer is 3,958.8 miles – the mean radius of the Earth in miles. In other words, if you dug a tunnel straight down, you'd reach the center of the Earth after going 3,958.8 miles, and then you'd need to go another 3,958.8 miles to reach the opposite side of the planet.
How far is the center of the Earth in feet?
The center of the earth lies 6,400 kilometers (4,000 miles) beneath our feet, but the deepest that it has ever been possible to drill to make direct measurements of temperature (or other physical quantities) is just about 10 kilometers (six miles).
How far would you have to drill to get to the center of the Earth?
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.
How long would it take you to fall to the center of the Earth?
about 42 minutes The gravitational force exerted on the traveler would be proportional to his distance from the center of the earth: it's at a maximum at the surface and zero at the center. The total time required for this trip would be about 42 minutes.
Can you dig to the core of the Earth?
Not only has no one ever drilled to the centre of the Earth, no one has ever even managed to drill through the Earth's crust. In fact, we know more about outer space than we do about what's under the Earth's surface! We know that Earth has layers. The Earth is made up of a crust, mantle, and core.
How long would it take to fall to the center of the Earth?
42 minutes The acceleration of gravity is 9.8m/s2 and the radius of the Earth is 6.378 million meters. This means that you would fall through the entire Earth in only 42 minutes! Can you imagine traveling 8 thousand miles in less than an hour? You maximum velocity at the center would be roughly 8km/s (18,000 mph).
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.
What is the deepest humans have gone into the Earth?
In terms of depth below the surface, the Kola Superdeep Borehole SG-3 retains the world record at 12,262 metres (40,230 ft) in 1989 and still is the deepest artificial point on Earth.
What would happen if you jumped through a hole in 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.
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.
What was found in deepest hole on Earth?
Metamorphic Rock The rock was found out to only be granite, even at the deepest part of the borehole. The change in seismic waves wasn't because of a change to basalt, but simply metamorphic differences in the rock. And then there was also the discovery of flowing water several miles in the Earth's crust.
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!
Has anyone been to the 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 would happen if the Earth stopped spinning for 42 seconds?
All of the land masses would be scoured clean of anything not attached to bedrock. This means rocks, topsoil, trees, buildings, your pet dog, and so on, would be swept away into the atmosphere.
How fast can a human go without dying?
Rapid acceleration and deceleration can be lethal to the human organism. Even Orion won't represent the peak of our speed potential, though. “There is no real practical limit to how fast we can travel, other than the speed of light,” says Bray. Light zips along at about a billion kilometres per hour.
How long would it take to get to Mars?
The trip to Mars will take about seven months and about 300 million miles (480 million kilometers). During that journey, engineers have several opportunities to adjust the spacecraft's flight path, to make sure its speed and direction are best for arrival at Jezero Crater on Mars.
Is there a bottomless pit on Earth?
Despite recurring outlandish claims, these turn out to be nothing more than urban legends, or hoaxes, upon closer inspection. It's true that there are plenty of deep holes that exist, but none are truly bottomless. In reality, even the deepest ones have never penetrated all the way down below the Earth's crust.
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.
What is at the bottom of the Kola Superdeep Borehole?
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 is the deepest man has gone into the Earth?
The deepest hole by far is one on the Kola Peninsula in Russia near Murmansk, referred to as the "Kola well." It was drilled for research purposes beginning in 1970. After five years, the Kola well had reached 7km (about 23,000ft).
What holds the sun in place?
Structure. The Sun is a huge ball of hydrogen and helium held together by its own gravity.
Why don’t we feel the Earth spinning?
But, for the most part, we don't feel the Earth itself spinning because we are held close to the Earth's surface by gravity and the constant speed of rotation. Our planet has been spinning for billions of years and will continue to spin for billions more. This is because nothing in space is stopping us.
What would happen if a human traveled at the speed of light?
Answer: Firstly, the physical consequence of traveling at the speed of light is that your mass becomes infinite and you slow down. According to relativity, the faster you move, the more mass you have. The same works on Earth when you're driving down the freeway.
Will humans ever travel at the speed of light?
So will it ever be possible for us to travel at light speed? Based on our current understanding of physics and the limits of the natural world, the answer, sadly, is no.
Do we age faster in space?
Training on the simulated martian terrain of Mars-500. Scientists have recently observed for the first time that, on an epigenetic level, astronauts age more slowly during long-term simulated space travel than they would have if their feet had been planted on Planet Earth.
How cold is Mars?
about -81 degrees F. Temperatures on Mars average about -81 degrees F. However, temperatures range from around -220 degrees F. in the wintertime at the poles, to +70 degrees F. over the lower latitudes in the summer.

What is the biblical abyss?
In the Bible, the abyss is an unfathomably deep or boundless place. The term comes from the Greek ἄβυσσος, meaning bottomless, unfathomable, boundless. It is used as both an adjective and a noun. It appears in the Septuagint, the earliest Greek translation of the Hebrew Bible, and in the New Testament.
