Marvel: My Super Ability Is Good Luck!

But some people still couldn't help but spit out:

"Stop making trouble, can you hurry up?"

"Everyone knows it's in the Mariana Trench in the Pacific Ocean."

"It's the deepest place on the earth's surface that humans have discovered, and the Challenger Abyss there is as deep as 11,034 meters deep!

Heard they fell for the trap.

Iron Man Tony․ Stark laughed wickedly,

"Ahh~ mistake!"

It's not that Tony. Stark is ignorant of the urgent situation.

However, according to his character,

He couldn't help but tease them.

By the way, leave yourself a little time to think about how to make the detonation plan to the center of the earth just now successfully implemented.

"Why not?"

The person who just complained stood up and asked:

"Isn't Challenger Abyss the deepest place?"

Tony shook his fingers and said thoughtfully:

"There's nothing wrong with the fact that Challenger Deep is the deepest place on the Earth's surface."

20" but not the closest to the center of the earth."

Facing the questioner's doubts,

Tony Stark gestured towards the famous physicist: green titan Banner,

It means let him explain.

Allow yourself time to think about how you can tackle the tricky business of transforming energy.

And the green titan Banner who has worked with Tony Stark for a long time also understands,

He stepped forward and said:

"My friend, don't get excited, since you asked, let me explain briefly.

With that said, the green titan Banner took a deep breath and said:

"The Mariana Trench in the Pacific Ocean is indeed the deepest known trench in the world's oceans, with an average depth of up to 8,000 meters.

The lowest point in the world and the deepest part of the ocean is the Mariana Trench east of the Mariana Islands in the western North Pacific Ocean.

The Mariana Trench is an arc-shaped depression on the ocean floor, extending 2,550 kilometers with an average width of 69 kilometers.

There are small steep valleys at the bottom of the main trench. In 1957, the Soviet survey ship measured a depth of 10,990 meters.

Later, according to the data given by the National Oceanic and Atmospheric Administration of the country M, the deepest part of the trench is located in the Challenger Abyss, with a depth of 11,034 meters.

So, is this the closest place to the Earth's center?

While the Challenger Deep is the deepest point in Earth's oceans, it's not the closest to the Earth's center.

This is because the earth is not a perfect sphere, but an ellipsoid.

The Earth is slightly bulged near the equator and slightly flattened near the poles, so the lower the latitude, the longer the Earth's radius, and vice versa.

The equatorial radius of the earth is 6378.1 kilometers, which is 7.1 kilometers longer than the average radius and 21.3 kilometers longer than the polar radius.

The polar radius of the earth is only 6356.8 kilometers, and the average radius is 14.2 kilometers shorter.

The latitude of the Challenger Abyss is 11.373 north latitude, and the radius of the earth here is about 6377.3 kilometers (greater than the average radius of the earth), so the distance between the Challenger Abyss and the center of the earth is 6366.3 kilometers.

In contrast, the bottom of the Kola Ultradeep Borehole is closer to the center of the Earth than the Challenger Deep.

The Kola ultra-deep borehole is the deepest borehole ever drilled by humans, currently ranking third in the world, and its deepest reaches 12,262 meters.

The Kola ultra-deep borehole is located at 69.397 north latitude, where the earth's radius is about 6359.4 kilometers (less than the average radius of the earth),

Therefore, the distance between the Kola ultra-deep borehole and the center of the earth is 6347.1 kilometers, which is 19.2 kilometers closer to the center of the earth than the Challenger Abyss.

Although the Sakhalin-I oil well is deeper than the Kola ultra-deep borehole, its deepest point is 12,376 meters.

But its latitude is farther south, at 50.654 north latitude, where the earth’s radius is about 6365.4 kilometers, so its distance from the center of the earth is 6353 kilometers, which is 5.9 kilometers farther from the center of the earth than the Kola ultra-deep borehole.

Likewise, the second-deepest well is located further south, and it is not as close to the center of the earth as the Kola Superdeep borehole.

Since the North Pole has the Arctic Ocean, and the polar radius is the shortest, will the bottom of the Arctic Ocean be the closest place to the center of the earth?

The deepest part of the Arctic Ocean is located in the Litke Abyss, with a depth of 5,450 meters.

Litke Abyss is located at 82.4 north latitude, and the radius of the earth here is about 6357.1 kilometers, so the distance between Litke Abyss and the center of the earth is 6351.7 kilometers,

That's 4.6 kilometers farther from the center of the Earth than the Kola Superdeep borehole, but 14.6 kilometers closer than the Challenger Deep.

Therefore, the Challenger Abyss in the Mariana Trench is not the closest place to the earth's center, but the Kola ultra-deep borehole dug by humans is the closest place to the earth's center. "

after listening

,

The original doubters were also in an uproar.

originally in their minds,

Challenger Deep in the Mariana Trench is the closest thing to the Earth's core.

But they never expected that they missed the simplest condition,

The shape of the earth.

It turns out that a hole drilled by humans themselves decades ago is the closest place on the surface to the core.

The Kola ultra-deep well is a scientific drilling project started by the former Soviet Union in 1970 in the area near the Norwegian border on the Kola Peninsula.

The deepest of these, SG-3, reached 12,263 meters in 1989.

In terms of vertical depth, this borehole was at that time the deepest man-made object on the earth.

However, its well depth records were broken in 2008 and 2011 by the Ashshin oil well (12,289 meters) in Qatar and the Odo390ptuOP-11 oil well (12,345 meters) in Sakhalin Island by Russia’s Ross,

Ranked third in the world.

It was drilled by the scientific research and development center "NEDRA".

Located in the Murmansk region, 10 kilometers west of the city of Zapolyarny.

The well was opened in the northeast of the Baltic Sea Shield, at the junction of the Precambrian ore-carrying mines.

The depth of the well is 12,262 meters, the diameter of the upper part is 92 cm, and the diameter of the lower part is 21.5 cm.

Well SG-3 is purely used for scientific research near the surface of the Moho without exploration purpose.

Therefore, the Kola ultra-deep well SG-3 is still the deepest parametric well in the world.

Its exploration work began on May 24, 1970.

Among the tens of thousands of scientific researchers, only a handful of scientists were able to participate in the research work on site.

All those who participated in the drilling work were given an apartment in Moscow,

The monthly salary level during the working period reaches the annual salary of a university professor.

Sixteen laboratories were set up at the drilling site to study the cores.

The entire research program was carried out under the direct leadership of the former Minister of Geology of the Soviet Union.

but,

Its final 262 meters were carried out between 1983-1993 and took a full decade.

Then the drilling was stopped, and the official reason given was insufficient funds.

Research continued for several years thereafter, until funding ran out in 2006. .
