A century Pejelajahan Radio To Reach Alien.
Since the discovery of radio a century ago, humans have malakukan broadcast into space in the hope of, any alien can listen and learn from our presence.
Although the waves reach a distance of 200 light-years in all directions, but it still takes light 118,800 years to reach the entire Milky Way.
Tiny yellow dots that look smaller than planet Earth in this photo released – reveals that so far there are limitations of broadcasting since Marconi discovered radio in 1895.
When we consider that there are billions of galaxies like our own galaxy in the universe, the search for extraterrestrial life may not end in a short time.
Science blogger, Adam Grossman, the man who created the diagram ‘Humanity Bubble’ using images renowned Nick Risinger, joked on his website: “It has made me feel small, sad and alone.”
However, if it will only spend four minutes to get to Mars when traveling at the speed of light, with a distance of 200 light-years is not a small achievement.
Given the recent evidence of an earthquake on Mars, it shows that there is alien life on the Red Planet. We all hope to be able to create a set of radio that can reach Mars.
