This is not science.
It is pure speculation, based on numerous assumptions.
Yes. Pure BS. Total rubbish.
The Drake Mistake.
Yes, but it’s still interesting to wonder about.
The sun is “good” for many millions more years.
Will human civilization last as long as our sun?
I doubt it.
Agreed. "Researchers" have a sample size of exactly one - humans - on one planet. That's a pretty poor statistical sample for what, about 100 billion stars in the galaxy?
Consider. First, the 100 billion number is just an estimate, no-one has actually counted them.
How many of those stars have planets orbiting them? Another estimate. As our technology and techniques have improved this guess, er, estimate has continued to change.
How many of those planets orbiting stars are in the "habitable zone?" Another guess.
How many of those planets in the habitable zones have the right elements in the right proportions to support life? Another guess.
How many of those planets have actually experienced life? Another guess.
On how many of those planets has intelligent life occurred? Another guess.
On how many of those planets has mere intelligent life evolved into civilizations? Another guess.
Finally, we get to the apparent reason for their "research" - on how many of those planets have these civilizations fallen. Another guess.
In the end, you can find fairly intelligent, well-reasoned arguments that the galaxy is teaming with intelligent life, or that it is a barren void, and just about any position in between. The real takeaway is we simply do not know and have no way of knowing - yet.
Absolutely agree!
It is pure speculation, based on numerous assumptions.
Actually, it IS science. The problem is, science is being morphed before our eyes and hoisted onto society as something that is settle fact.
There was a recent post on social sciences, that featured this brilliant give and take involving a Harvard faculty member critical of Charles Murray from the original article, that is worth reprinting - it is with regard to the "certainty of SCIENCE":
"so why should we let someone teach social science that we know to be wrong in our social science courses?"
Because it is possible that you are wrong.
Science is not mathematics. Newtonian physics was wrong. And social science is a further three rungs down in certainty from science.
Your level of certainty and arrogance about what can be said, and probably thought, smacks of religion, and not science. This is a political religion that permeates academia at the moment. And which I am fairly sure you will swear does not infect you, while the rest of us can see the symptoms quite plainly.
Only religions ban heretics from speaking because of the wrong-think they might cause. Real science loves a good heretic. In fact, honestly, the entire goal of science is to be a heretic. To have an idea that no other person ever had. Science is the pretty much the antithesis of your thought-police approach.
And most of academia used to be the antithesis of your thought police approach as well, until the religion of leftism took it over, with the direct help of people like you.
Someone had some computer time they had to use & needed one more publication for their yearly P&T evaluation.
Just like America’s cities.
It’s nonsense, not enough time or material in the universe for the self generation of life.
It is pure speculation, based on numerous assumptions.

Yep, sounds like a lot of anchoring going on.
Exactly:
“But, assuming life does arise reasonably often and eventually becomes intelligent...”
A “study” where they assume their conclusion!
Here, I’ll do my own study:
“Study shows Live Science Studies are Hogwash”
Assuming Live Science publishes studies based entirely on circular logic reasonably often, we conclude that Live Science is essentially hogwash at its core.”
Wow. I will have to get another BS article based on science fiction. Heinlein is dead....
“It is pure speculation, based on numerous assumptions.”
After reading your statement, global warming comes to mind. But with global warming there is a political motivation.
Indeed it assumes all planets and human life evolved at the same rate impossible.
You just described 80% of all cosmology...
Your response completely correct
yea aliens...
It’s bad sci-fi.🙄
