I am definitely fascinated by this story.
Fascinating that they’re employing artificial intelligence/machine learning algorithms to discover patterns. I guess we should be expecting AI everywhere during this digital revolution we're in.
in the early 1900 Albert Einstein continued the work of a scientist by the name of Lorentz. It was on general relativity. The bases of; the theory of relativity is light and the speed of light. One of the conclusions of all work on relativity is: we cannot travel at the speed of light.
1) And so, all objects that are more than a few earth years away from us, are unreachable. Either by us or by them. And so, how would anyone living outside our planetary system ever reach us? If we could find a way to travel at sub light speed for ever, it would take thousands of years to go anywhere. And for what? and think of the evolution of the travelers, they would not be anything like the creatures that left their home.
2) in the 1960's they did all sorts of monitoring of radiation/radio signals in all directions, they found nearly identical signals. And so the sense is, the universe is expanding like a balloon. Making all travel paths arcs. So, unless worm holes are real, impossible to take short cuts.
3) Earth's atmosphere, size (so gravitational pull), location relative to the sun, etc. led to human life (even you religious guys...read up on the Higgs Boson, you will find that creationism and evolutionism are not mutually exclusive...the inner most part of all particles is: empty space...read the book of genesis: and from nothing came ....). So the odds that another such setup exists is negligible. Thus making humanoide living creatures virtually impossible.
4) Read your Professor Hawken's work on black-holes and the theory of time. The big bang theory and singularities..Effectively all existence may have began at one moment in time. Thus making all entities in our Universe the same age. Why would you expect some life form to be so much more advanced than we are? and physical limitations on us (not being able to travel at the speed of light), not apply to them?
We are alone. One tiny planet, the 3rd from the sun. Who, thanks to incredible circumstance has life on it. (again, whether God, accidentally or a a combination of God and accidents). If in the millions of entities out there, another body is similar and has something living on it, we will never know. We are receding as a people. As our population grows, food will be our sole preoccupation. What is out there will have zero meaning. In 100-1000 years, we will not be living in space, or doing a whole lot of sci-fi. We will be trying to eat on a planet that is experience soil erosion at 1-2% a year, that continues to grow at 1-2% a year and when a cross over point gets hit...then you religious guys need to kick in, because: God help us.
Save the millions spent on crap, use to it create a balance of life here. So that our descendants can have food and water and air and pharmaceuticals to survive. Otherwise, we risk two stone ages.
