Question

Do alien really exist? Breif Discussion please..

Answer 1

hey...here is your answer.........❤️❤️❤️

The Milky Way has about a hundred billion stars in it, with some estimates four times larger than that. In 2009, NASA launched the Kepler spacecraft to search for planets around distant stars. What the Kepler mission found was nothing short of astounding. We know that most stars have planets (over 80%). About a quarter of those planetary systems have a planet at a distance from the star that would allow for liquid water. And, of those, 10% to 20% of the time those planets are around the same size as Earth. Combining those numbers, we can estimate with some accuracy that the number of possibly habitable planets in our galaxy is in the neighborhood of 2 billion.

While there is some uncertainty in this estimate, it is relatively firm. We are far less certain in our estimation of whether life will be created, if it will survive, and if intelligence will evolve. If these life-related probabilities are high, say above 50%, then life should be extremely common in our galaxy. If those numbers are low, we could be alone.

For all these factors, we only have our own Earth to guide us. And, of course, generalizing from a single instance is not a wise thing to do. However, we are not completely ignorant even with just our single planet to study.✨✨✨✨✨✨
