The Secret to Life in the Universe: The Goldilocks Zone and the Three-Body Problem

The secret to life in the universe has been researched extensively. Our world is a magnificent planet that is home to many life forms and is full of life. People, animals, and plants living on Earth are very lucky in a sense because as far as we know, there are no other known living species in our solar system or near our solar system. According to some scientists, there may be microbial life on Jupiter’s moon Europa or Saturn’s moon Enceladus. It is thought that there may be frozen oceans on both planets’ moons, and that there may still be heat in the center of these moons, and that there may be microbial organisms living in the depths of the ocean. However, it is thought that it is impossible to find plants, animals, or intelligent life forms either here or around our Solar System. So what happened is that while there are 9 planets in the solar system, including Pluto (normally Pluto is no longer considered a planet), life only emerged on Earth. In fact, if we count the interstellar space around us, why can’t we find any traces of life other than us? The most basic reason for this is the concept called the Goldilocks zone and this has even been mentioned in the world-famous TV series the Three-Body Problem.

What is the Goldilocks Zone?

The Goldilocks zone refers to the region of a planet orbiting a star where the ideal conditions for liquid water to exist are present. This region is also called the “habitable zone”. It takes its name from the fairy tale “Goldilocks and the Three Bears”. In the fairy tale, the golden-haired girl Goldilocks visits the homes of three different bears until she finds the house where everything is “just right”. Similarly, when a planet is in the Goldilocks zone, it means that the elements such as temperature, atmosphere, and water needed for life to develop are “just right”. The importance of the Goldilocks zone requires

• Presence of liquid water: Liquid water is the most fundamental element for life as we know it. Many biochemical reactions occur in water and are necessary for cells to function. The Goldilocks zone ensures that the surface temperature of a planet is high enough for water to remain liquid, but low enough that it does not evaporate.

• Composition of the atmosphere: The right atmospheric composition is also important for life to thrive. The atmosphere protects the planet from harmful radiation from the sun and regulates temperature. Planets in the Goldilocks zone tend to have atmospheres that contain the oxygen and other gases necessary for life.

Distance: The distance of a planet from its star is also important for the Goldilocks zone. Planets that are too close to the star are extremely hot, while those that are too far away are extremely cold. Planets in the Goldilocks zone receive the right amount of light and heat for liquid water to exist, and are also at the right distance for biochemical reactions, such as photosynthesis, to occur in the atmosphere. Also being too close to the sun and its activity can prove harmful to the planet and its living occupants.

Discovery of the Goldilocks zone

The idea of ​​the Goldilocks zone was first put forward by astronomer Harlow Shapley in the 1930s. Shapley noticed that the amount of light a planet orbiting a star receives depends on the planet’s orbital distance from the star. This suggested that some planets would be in the temperature range necessary for liquid water to exist. The Goldilocks zone idea was further developed by astronomers in the 1960s and 1970s. During this period, scientists began to consider other factors that might be necessary for a planet to be habitable. These factors include the composition of the atmosphere, the planet’s magnetic field, and its geological activity.

The Goldilocks zone and space exploration:

The width of the Goldilocks zone varies depending on the type of star and its brightness. For stars like the Sun, this zone covers an area of ​​about 0.5 to 2 times the distance from the star. Outside this zone, planets are either too hot and water evaporates or too cold and water freezes. Scientists use various methods to study the atmospheres of planets in this zone and search for the presence of water. Space telescopes and spectrometers are used to measure the atmospheric composition and temperature of these planets. In addition, space probes and sensors can directly search for water on the surfaces of these planets. The Goldilocks zone is an extremely important concept for space exploration. Scientists use telescopes and probes to search for Goldilocks zones in our solar system and other star systems. These studies could help us discover the existence of extraterrestrial life. However, there is still much we don’t know about the Goldilocks zone. For example, we don’t know exactly what composition the atmosphere of a planet must have for it to be habitable. We also don’t know if life exists outside of the Goldilocks zone in our universe.

Are There Any Exoplanets in the Goldilocks Zone?

However, the idea of ​​the Goldilocks zone has fundamentally changed the way we search for life in the universe. We are no longer just looking for planets similar to Earth, but also for any planet or exoplanets where liquid water can exist. This could help improve our understanding of how common life is in the universe. Research on the Goldilocks zone and exoplanets provides information not only for space science, but also about the climate and future of the Earth. It is being investigated whether climate change will cause the Earth to leave the Goldilocks zone and what the effects of this will be on life.

The Goldilocks zone is a concept that shows the delicate balance of life in the universe and how rare and valuable the existence of life is. In fact, if we think of the famous book or series The Three-Body Problem, the living community there lives on a planet orbiting 3 stars, and because the planet is not in the Goldilocks zone, the civilizations established by the living beings on this planet are constantly destroyed and forced to start over. They have stable and unstable eras in the 3-Body Problem and due to the nature of physics, it is impossible to guess the exact orbits in a three-body problem. Hence, the Santi decide to come to Earth. In fact, this series or book also shows that the Goldilocks zone is very important for both life and for the survival of intelligence. Let’s say that for now, we are lucky that our planet is in the Goldilocks zone as human beings, but maybe one day we will discover other planets that fit this description.
