Intelligent life in the universe is rare. Rare and light years away from other intelligent life.
Most life in the universe would be of the complexity of slime or maybe single cell life. Finding a culture capable of building a Hubble telescope or splitting the atom would be quite a discovery
If they were to locate us, they would stay and contact us.
It is light years away from the next possible planet that can sustain life
I disagree. I think this solar system (
The Milky Way) is over flowing with life. See this
That dot which is circled is earth. It was taken by the Voyager 1 space probe in 1990. The distance was 3.6 billion miles away.
Every person that has ever lived and died did so on that dot. Every war, species, invention all happened on that pale dot,
There are hundreds of billions of planets (dots) in our galaxy and there are hundreds of billions of galaxies in the universe, each with hundreds of billions of planets (dots)
The idea that a single dot in the vastness of the cosmos is the only planet with life is just…nonsensical.
The search for extra terrestrial life relies on radio telescopes. Radio waves travel at the speed of light and humans have been broadcasting them for the better part of a century. So, how much distance has been covered in that 100 year period? This will help:
That blue dot in the cutaway section is around 200 light years in diameter. So basically human's have only been able to broadcast 100 light years away in any direction. The center of our galaxy is 26,000 light years away.
Needless to say, humans radio waves have not gone very far.
And if something was there to receive the message and respond, it would take 52,000 light years to get back. Feel free to wait.
And in order for humans to receive a radio wave from an alien world, humans radio telescope(s) have to be pointed directly at the spot in which a radio wave might be picked up, on the exact date and time in which that radio wave will reach earth.
Also what if that alien civilization is far more advanced than human's are and they don’t use radio waves anymore ? What their planet has gone extinct? Or, they are more primitive than humans are and have not yet discovered radio waves ? The X factor is endless.
It's a bit premature to make claims that life does not exist anywhere else in the universe. If life can evolve here using the most abundant elements in the cosmos, life can evolve elsewhere.
Life on Earth is made up of hydrogen, oxygen, carbon and nitrogen. Those four elements, along with helium, are found throughout the macrocosm in abundant supply.
