When talking about the already majukah human civilization? If it is indeed already advanced, then how nilanya? Then there is the quantitative method to measure it Kardashev scale is called. Created in 1964, the Kardashev scale aims to measure the level of progress of human civilization based on how humans generate energy. Formulated in 3 stages, Nikolai Kardashev (Astrophysical scientists leading Russia) send into phase 1, phase 2 and phase 3.
In the first stage the level of progress, human civilization is able to produce energy from all energy that reaches Earth from the Sun. To achieve the progress of the civilization phase 1, mankind must envelop the whole earth’s surface with solar panels that will of course be a not too pleasant for livable. But in the future, mankind can pair a very large solar panels in space satellites and transmits its energy to Earth via laser. This is very likely to occur and is currently still under development in the laboratory (Leopold Summerer & Oisin Purcell, 2009). After mankind was able to achieve this, then we reach civilization progress stage 1.
The second stage is the human race was able to utilize the entire energy from the Sun to produce energy. Unlike the first stage emphasized at the energy up to the Earth, and only partially just energy gets to Earth. On the second stage was the capture whole energy emitted by the Sun. To reach the stage, the human race must make a Dyson sheath apparatus transparent energy harvesters enclosing the entire area of the Sun as shown in the picture below. Dyson has been dianalis and sheath do calculation mathematically about on what the most optimal radius to get energy. It can be read on paper courtesy of Viorel Badescu in 1995 entitled “The Radius of Sphere Dyson’s” (Viorel Badescu, 1995).
The third stage is able to utilize the entire energy that exists in the Galaxy Andromeda. To achieve this, the human race must be able to access the energy from the black hole supermasif contained in the center of our galaxy. Ways and mechanism of phase 3 is still not formulated until this article was created. Kardashev stop number 3 on his scale, but other scientists have proposed levels even further.
Level 4 is able to harness the energy that exists in the entire universe consists of several groups of galaxies. And most recently, the level of the 2nd phase 5 is able to utilize the entire energy of the universe.
So, how does the scale of humanity at this time based on the Kardashev scale? In 1973, the famous astronomical genius named Carl Sagan estimated that we were still in the numbers 0.7. And now, in 2017, the value we are on number 0.72. Scientists estimate that humans will achieve stage 1 in 100-200 years, stage 2 takes 1000-2000 years away, and phase 3 membutukan least 100,000-1.000.0000 years again.
Thus, Kardashev scale based on a, from the year 1973 until 2017, the human race was not very forward-forward.
