Humans cannot leave the solar system

What happened to Voyager

By Karen GillanahPublished 2 years ago 4 min read

The Earth orbits in the vast solar system, and together with the Sun and seven other planets, it forms the solar family. As a member living on Earth, humans have never left the solar system since its inception.

For humans, it is almost impossible to leave the solar system. Long interstellar distances trap humans in a corner of the universe, and the river of stars will wrap us up on Earth. And the history of the Voyager encounter, but also once again proved that mankind can not get out of the solar system at this point, this is how it is?

The farthest away from the Earth's spacecraft

With the continuous development of human science and technology, the exploration of space for human beings is no longer an unattainable dream. Exploration of the universe for mankind, both an unknown journey is also a civilization across.

The spacecraft invented by mankind carries the dream of the human universe. Since its invention, the spacecraft seems to be born for solitude, in the vast and endless universe, always flying toward a distant goal, alone on an endless interstellar journey. And Voyager 1, is in this interstellar journey of the most lonely vehicle.

Voyager 1 is a space probe launched by NASA in 1977, the initial mission is to help humans explore Jupiter and Saturn.

However, during one of its missions, Voyager 1 deviated from its original orbit due to the gravitational influence of Titan, so NASA eventually decided to change Voyager 1's orbit and let it continue its "journey" in space.

In 45 years, Voyager 1 has traveled nearly 23 billion kilometers in space, making it the longest-distance flying vehicle in history. Interstellar travel for Voyager 1 is both a romantic and lonely journey.

From the moment it left Earth, Voyager 1 was destined never to return to its home. During its long journey, Voyager 1 has witnessed both the majesty of Saturn's rings and the treacherous beauty of Jupiter's aurora borealis.

Nearly 6.4 billion kilometers from Earth, Voyager 1 turned back to capture its last images of the planet, saying its final goodbye to Earth and continuing its journey into deep space.

As of today, Voyager 1 is still operating normally, traveling into the unknown of space. The energy carried by Voyager 1 can support Voyager 1 to continue to fly until 2025, and after 2025, Voyager 1 will be completely disconnected from Earth, becoming a "forever wandering" space probe in interstellar space.

Solar system cage?

As the farthest-flying vehicle in human history, Voyager 1 to about 17 kilometers per second at ultra-high speed in space, so far, Voyager 1 has been in space for nearly 23 billion kilometers.

But even so, Voyager 1 has not yet flown out of the solar system, it has reached a place just out of the area affected by the solar wind. For Voyager 1, it will take at least another 40,000 years to get out of the solar system.

But this long-time assumption for the human race itself is a paradox, in 40,000 years, even if Voyager 1 can get out of the solar system, the human race has long ceased to exist.

And for humans, out of the solar system is not just a simple matter of crossing a long distance our solar system for us is likely to be a "cosmic cage" like existence.

How big is our solar system? The universe does not give us an exact answer. Most of the solar system we know today is defined by humans themselves. Initially, we used Neptune as the dividing point between the solar system and extrasolar space, and later, we used the Oort cloud as the new solar system dividing point.

If we use the latest Oort cloud as the boundary point, then the diameter of the solar system will reach 200,000 astronomical units, which is 2.99x 109 km. Whichever is the historical point of demarcation, it is a very distant existence for us. With such a long distance, it is as if we are trapped in a "giant cage".

And because the sun is constantly evolving, the strength of the solar wind emitted by the sun is also constantly changing. The change in the strength of the solar wind will bring about a change in the range of the "heliosphere top" in the solar system. Therefore, when the vehicle crosses the top of the heliosphere, the resistance is not clear.

How to fly out of the solar system?

For human beings, if they want to fly out of the solar system, the main point is to overcome the long distance in interstellar space. And humans want to cross such a long distance in a short time, which means we need to develop a vehicle that can reach the speed of light.

But according to the current human technology, the development of light-speed vehicles for us is almost impossible. To reach the speed of light, then we need to be able to reach the speed of 300,000 kilometers in 1 second. Take the speed of Voyager 1 as a comparison, Voyager 1 is currently able to achieve the speed of 17 kilometers per second.

Obviously, in front of the speed of light, Voyager 1 is like a slow-moving "turtle". Increasing the speed of the vehicle in a short period is extremely difficult for humans, so on the technical level, we still need a very long time to develop a higher-speed vehicle.

If you can not reach that fast speed, then you can only invest a lot of time in interstellar travel at the cost of a long distance to cross. We all know that the human life span is limited, if you want to cross the long interstellar distance, then you have to develop the "frozen body" technology so that you can enter a dormant state.

For humans, it is extremely difficult to cross the long interstellar distance. The only thing we can do now is to develop science and technology in the hope that someday in the future we can develop a high-speed spacecraft to support our interstellar travel.
