“Two possibilities exist: either we are alone in the Universe or we are not. Both are equally terrifying” – Arthur C. Clarke
There is a pretty good chance that we are not alone in the Universe, that’s because there are billions of planets in our galaxy alone and some of those are similar to earth. Now to understand why there is the possibility of life on another planet, we need the understand the basic ingredients that create life on Earth.
Water, carbon or nitrogen and an energy source like the sun. So scientists are putting their efforts to study more and more about planets similar to earth. If they are similar to earth, then there is a great number of chances that we are not alone.
But still, scientists haven’t found an alien. Because space is so large that we have an observable universe of 46.508 billion light-years, which is nothing in comparison to the actual size of space.
In 1977, NASA launched Voyager 1. It was launched with a Golden Record for an alien civilization to find and listen to. If they discover this, it’ll be a great way for them to learn about us and find where we live.
It contains greetings in 55 languages, earth’s sounds like volcanoes, wind, rain, frog, elephants, heartbeat, train, tractor and even a kiss, traditional music from different cultures, recording of brainwaves, 116 pictures of human life and direction back to earth.
Everyday Voyager 1 moves further away from earth and the Golden Record can be played for more than a billion years. In 40 years since Voyager 1 was launched, it was travelled more than 17 trillion kilometres.
Between September 16, 2018, and October 30, 2019, researchers have detected unknown signals occurring every 16.35 days. Over four days, the signal would release each hour. Then, it would go silent for another 12 days. The expected source can be half a billion light-years away.
