Fifth-level planets: human activities affect the earth in a “mixed” state

A new study suggests that the enormous impact of human activities on the Earth or the Earth will enter a “mixed” state, to the next planet level transition.

一项新研究指出,人类活动对地球产生的巨大影响或将使地球进入一种“混合”状态,向下一行星级别过渡。

Many of the ideas for advanced civilization come from the Kardashev scale in the process of scientists’ tireless search for alien life. The system was originally proposed in 1964, according to the hypothetical alien life can use the energy level to alien civilization grading. But scientists in a new study to further, put forward a new classification mechanism. The basic idea of ​​the mechanism is that the living creatures on a planet can have an effect on its energy flow, making it unsynchronized with the advanced level of civilization. According to this system, experts say that the Earth may be from the four planets (that is, biological activity began to have a significant impact on the planet’s energy flow) to the final five planets. On the fifth-class planets, “energy-intensive species” will have a huge impact on the planet. Earth is currently in the “human world” stage, with the impact of mankind as a significant sign.

Researchers point out that human activity even affects the evolution of the entire planet. “We assume that from the perspective of cosmic biology, Earth’s entry into the human world indicates that we are moving towards the next planet level,” says researchers at the University of Rochester and the University of Washington. “We have studied this problem from the perspective of the solar system and extraterrestrial planets, and in our view, entering the human world can be seen as the beginning of the ‘mixed’ state of the earth, from the current planetary level to the next level “The new classification system is based on” non-equilibrium thermodynamics “(non-equilibrium thermodynamics). It refers to the extent to which energy flows do not match in the process of “free energy generated by non-biological activities, biological activities and technical activities on the planet”.

In general, planets can be divided into five levels.

The first level consists of a planet that does not have the atmosphere, such as Mercury and the Moon.

The second level is to have a thin atmosphere composed of greenhouse gases, but there is no life of the planet, such as Mars and Venus.

The third-stage planets may have a thin, bio-viable atmosphere, and some biological activity, but not enough to affect the evolution of the planet. Researchers say the current solar system does not have such a planet, but early earth, and even Mars (if it really once had life) may have belonged to this level.

The fourth stage of the planet has a suitable biological survival of the dense atmosphere, photosynthesis and surface organisms began to have a significant impact on the energy flow of the planet.

On the fifth level planets, “energy-intensive” creatures will have a huge impact on the evolution of the planet.

While the grading system will help to find developed extraterrestrial life, the researchers are more concerned with the importance of using the system to understand the state of the earth. “We found seven extraterrestrial planets in the relatively close Trappist-1 planets, which necessitated a reexamination of life on Earth,” says Marina Alberti of the University of Washington. “This enriches our understanding of the dynamics of coupled galaxies and provides a new way to pursue long-term sustainable development: the ecological evolutionary dynamics that form a mutually beneficial and win-win relationship with coupled galaxies.”

This The new classification system may also lay the foundation for future research on the common evolution of planets, energy-intensive civilization living on these planets will have a huge impact on it. Scientists point out that these planets must be considered as a continuum of these interactions. “Any planet that can support energy-intensive civilization for a long time must have similar thermodynamic properties.” The authors write that ” These features, even if they only understand their outline, can help us to understand the direction of the next effort to make human civilization more sustainable. “Or, in short,” if we do not even know the future direction of development Figure 2: Earth is currently in the “human world” stage, with the impact of mankind as a significant sign.
