How would an alien civilization change if they met us? It would forever change both their and our civilizations much as the recently discovered Brazilian tribe pictured below will be forever changed by modern mankind, which they didn’t even know existed until fairly recently. The photo is an aerial shot. No one has met these people yet.
Exactly! To date, no life has been found on any other planet or meteor. We would really like to find life elsewhere, and the most likely candidates within reach would be the moons of Jupiter and Saturn.
Beyond that you have to go interstellar. Since it would take hundreds or even thousands of years to reach even the nearest stars at the fastest speed we’ve ever achieved in space, interstellar travel is unlikely now or in the future.
Put away Star Trek and Star Wars. Aliens are not visiting us and we are not going to visit them, whatever they may look like.
I know. It’s old news already. Everybody knows. Here’s the new take on it. Follow along.
Imagine we want to go to some place that might have life. We don’t know if there’s life or not, but we want to go and find out.
To quote the NASA website, designed to generate funding for NASA so that Trump won’t cut it out of existence, it says: (This is where the old news already follow along part comes in.)
|NASA’s Spitzer Space Telescope has revealed the first known system of seven Earth-size planets around a single star. Three of these planets are firmly located in the habitable zone, the area around the parent star where a rocky planet is most likely to have liquid water.
The discovery sets a new record for greatest number of habitable-zone planets found around a single star outside our solar system. All of these seven planets could have liquid water – key to life as we know it – under the right atmospheric conditions, but the chances are highest with the three in the habitable zone.
“This discovery could be a significant piece in the puzzle of finding habitable environments, places that are conducive to life,” said Thomas Zurbuchen, associate administrator of the agency’s Science Mission Directorate in Washington. “Answering the question ‘are we alone’ is a top science priority and finding so many planets like these for the first time in the habitable zone is a remarkable step forward toward that goal.”
Bla bla bla. To date, no extraterrestrial microbe has ever been found — not even in our own solar system. We have not even found a fossil of a microbe. We have no idea whether life exists on any other planet in the universe other than here.
We want to find life. It will finally prove life evolves. No need for God!
It hasn’t happened yet.
Is it possible life exists elsewhere? Yes.
No proof of that above statement exists.
GIven so, are we being visited by aliens and is the bungling government covering it up? No.
Anyway, how do we go and find out? That’s 40 light years away. It would take the fastest spaceship 700,000 years to get there.
We’d need a generational spaceship. You and your mates blast off. You live your life on the spaceship. You have kids. You die. They have kids, they die. For many generations. Finally you arrive. Just like Earth traveling through space.
Well, guess what? We are already on a generational spaceship. It’s called Earth. It’s traveling through space. Generations come and go. Sometime in the future we may or may not see if there’s life out there other than us. No need to build a spaceship.
