Rare Earth Hypothesis - Assignment Example

The theory also explains that most of the universe's large parts do not support complex life calling the places to be dead zones. The places that support complex life are known to be the habitat zones for living creatures.

The habitat zone acts as a primary function having a distance from the galactic center. When the distance between the two places increases, the stars’ content begins to reduce creating terrestrial planets. The dangerous x-rays that are produced from the black hole found at the galactic center including the stars of the neutrons and quasars become less intense. This creates hell the life and enables the hypothesis to identify the early life of the universe. Also, the gravitational that occurs between the stars and the planets becomes less due to the low density caused by the decrease of the stars. This explains that if a planet is far from the galactic center, it is likely to have been hit by a bolide. It is an impact that affects complex life.

2. The population density for the galaxy proves to be 50,000 light years. Having 2, 500 civilizations while assuming that they are equally spaced, their separation will be found by dividing the light years by the civilizations. One civilization will prove to have 20 light years.

3. There is a compatible function between humans and nature itself. In nature, several circumstances lead to human survival. Science and nature have also a new version of the relationship between humans and nature. It proves that the physical substances that surround human beings are complex. There is also a lot of interdependence between humans and nature. This begins with the human genes that can produce several traits creating survival. The lives that are on earth form life that is found only in the biosphere which is the membrane of both plants and animals. On the same note, all the resources like oil are formed due to the heat of volcanic that is experienced under the crust of the earth. Humans have tried to sustain themselves by developing characters that help them to survive. Human beings have the right characteristics to foster sustainability. Human beings can adapt to the new change in the environment making them to adapt new ways of survival. It can be related to desert plants that adapt to the environment by shading down all their leaves to keep the little water they absorb from the soil. Some of the characteristics of human beings include adaptation to climatic changes whenever they are exposed to bad weather. The sharp minds of human beings make them analyze and detect any danger that may face them. Read More
