Is anybody out there?

Because one of my hobbies is Astronomy so I would like to share with you a new topic and I hope one day I will have my own telescope.

“During the past 2 billion years, millions of Sun-like stars have passed near our solar system, yet there’s no indication that extraterrestrial have ever come here. An advanced civilization close enough to transmit purposely toward Earth would also be close enough to have discovered with its own space telescopes – Earth’s remarkable atmosphere and, thus the existence of Earth life, long before humans evolved here. Stars that are now within a few hundred light –years of Earth have already been our neighbors for millions of years. If extraterrestrials discovered 1 million years ago that Earth is a living world, what might they have done next? Should we learn that life exists on a world orbiting a nearby star, how could we resist the temptation to go there? How else could we determine whether alien life is constructed from the same molecules as terrestrial life and see what a real alien creature is like? Having long ago discovered our living planet with their space telescopes, the technological extraterrestrial would very likely have had the curiosity to investigate Earth. But clearly, they have not come, because once here, after a very long and potentially dangerous voyage, why would they leave? We can therefore be virtually certain that no nearby civilization exist. Perhaps the nearby extraterrestrial are not interested in building a space telescope capable of discovering living worlds or, once found, traveling to investigate those worlds. Earth could have been identified from afar as a living world. Any technological civilization that came within a few hundred light-years of Earth during the past 2 billion years would have had to choose between floating by for millions of years and never learning about terrestrial life, or, alternatively, sending a spaceship to our solar system. But at this very moment, at least 15,000 stars within 300 light years of Earth host Earth-mass planets in their habitable zones – yet there’s a great silence. Will we discover intelligent life beyond Earth? I’m clearly inclined to believe we will.”

Ciao Michaela! Anche a me affascina l'Astronomia ed il pensiero di altre forme di vita nell'Universo... Sono d'accordo con il tuo post: se gli extraterrestri fossero su una stella vicina, sarebbero già venuti a visitarci...sono anche affascinata dalla teoria secondo cui gli alieni sarebbero tra noi,camuffati da esseri umani...chissà se un giorno si manifesteranno...lo spero!

If there are aliens among us what do you think they want or what are they looking for? Also how did they get on Earth without being seen? Is anybody out there? 13669

Sono molto affascinata dalla "teoria" presentata nel film "Men in black", riguardo al rapporto tra umani ed alieni...

I didn't know about this movie but it looks more like a fantasy movie, but it's also interesting. However I don't believe that aliens are disguised as humans. Is anybody out there? 71293
