Through the Earth: why it is impossible to build a tunnel to the other side of the planet.

According to ТСН: The idea of a tunnel connecting opposite points on Earth often appears in science fiction. But modern studies show that such a project is impossible due to physical and technical limitations.

The studies in question detail deep geophysical observations.

Research Limitations

The deepest borehole drilled by humans, the Kola Superdeep Borehole in Russia, reached a depth of 12,263 meters. At these depths, water-saturated rocks and metamorphic granite were discovered, which came as a surprise to scientists.At the same time, China has begun drilling a 10-kilometer mine, but this is only part of the way, as the thickness of the continental crust is about 30 km, and the oceanic one is about 7 km, which causes additional logistical problems.

Physical Barriers

The main barriers are the immense pressure and high temperature. Pressure increases by one atmosphere every three meters. Near the planet's core, it is so great that ordinary substances turn into 'atomic soup'. The temperature in the outer core can reach 5,200°C, making it impossible to cool instruments.

Even imagining materials capable of withstanding the temperature of the Sun, the inner core of the Earth, which consists of a massive solid sphere of nickel and iron, becomes the next obstacle. At the center of this sphere, any object would be in a state of weightlessness, and after crossing the center of gravity, would begin to 'stretch' in the opposite direction. Scientists emphasize: a tunnel through the Earth is impossible not just due to technical limitations or lack of funding but because of the fundamental properties of matter and the laws of physics.

It should be noted that it was previously discussed what astronauts experience in space and what smells arise in outer space.

In conclusion, the discoveries and explorations of the deep layers of the Earth remain a mystery. Scientists continue to seek answers to questions about the deep structure of our planet, but the idea of creating a tunnel through the Earth remains in the realm of fantasy. Furthermore, for example, more detailed studies of complex geological conditions may help to understand not only our planet but also other celestial bodies.
