A new study... provides an updated estimate of the likely number of alien civilizations that could exist in the Milky Way. The analysis...starts with revising the Drake equation...
"The classic method for estimating the number of intelligent civilizations relies on making guesses of values relating to life," said Westby in a press release. "Our new study simplifies these assumptions using new data, giving us a solid estimate of the number of civilizations in our Galaxy."
Westby and Conselice...built a key assumption in to their estimate: Life on another planet will arise in a similar way to how it did on Earth.
The duo placed three different sets of limits on these "suitable planets" harboring life with weak, moderate and strong categories with different time frames for life to arise.
The weakest limits allowed them to make estimates on a time frame of greater than 5 billion years, while the strongest limit only assessed worlds between 4.5 and 5.5 billion years old.
When plugging the strongest limits and numbers into their complex new equation...data reveals there could be a minimum of eight CETI civilizations within the Milky Way.
On the other hand, using weaker limits, Westby and Conselice suggest there could be as many as 2,900 worlds where life has found a way that means we may be able to detect them sooner.
Though an interesting new way to examine an age-old question, the work relies on a lot of assumptions. The authors make it clear there is only one data point for intelligent, communicating life and that is humanity. Using us as the basis for other life in the cosmos may itself be flawed because the truth is we simply don't know what other intelligent life might look like or where it might thrive.

We’re transmitting on AM, and they’re listening on FM.
so thats a big fat zero then. man, where is my grant money?
The short of my theory is a civilization that advances too far down the tech tree gradually is effeminiatized by more and more technology and steadily grows more decadent and libtarded until it collapses. I think there might be something to it...especially with recent events.

Local phenomenon. Other civilizations have better sense, which is why we seldom visit other than to experiment on you.
Many sublime ...
Show us incontrovertible proof, excluding Earth, that even one alien civilization exist?
And do they have a God? Oh wait, they don’t believe there is a God.
Even among their IMAGINARY alien civilizatons.
Are most Scientist are full of it?
On your Kardashev scale: There are currently a few more than 8 Type III civilizations with the rest of the 2,900 worlds being broken into Type IIs and Type Is with Type 1s predominating - not counting Orbitals, Rings, and Shell Worlds, nor the billions of individuals living on various General Service Vehicles.
But you’d know all this if you hadn’t been so stupid (indelicate, but true) as to disregard men like James Clarke Maxwell and Nicole Tesla.
Sure as hell, DONT count earth among them.
No, these are not "solid estimates". These are guesses based on updated values. There is a huge difference.

"To consider the Earth as the only populated world in infinite space is as absurd as to assert that in an entire field of millet, only one grain will grow." -- Metrodorus, 4th c BC Greek philosopher
"Heaven and earth are large, yet in the whole of space they are but as a small grain of rice. How unreasonable it would be to suppose that, besides the heaven and earth which we can see, there are no other heavens and no other earths." -- Teng Mu, 13th c AD Chinese philosopher
"But I am not really willing to accept your premise, because it may well be that the means of communications they have are of a kind that we do not know how to receive, and that they would not have the means of communicating with sufficiently powerful radio or optical signals. That is something which, technologically, is too difficult for them but they would have some other means we would not recognize." -- Thomas J. Gold, 'Communication with Extraterrestial Intelligence' (Sagan, ed)
A planet where Coronavirus rules.
It’s life, Jim. But not as we know it.
And that is just in one multiverse
The more civilizations that are out there, the less likely that we would be first. If you want to contact one of them, it makes more sense to listen than to talk.
Where do you see any system going from the simple to the more complex regardless of energy flow (?)
Simple one: salt separating from water.
Entropy is salt mixed with water. evaporate the water, and you have salt and water, not the mixture, a lower level of entropy than the solution.
There are pretty complex crystals that are formed in nature, complex geological shapes, for example.
I admit, those are nowhere near as complex as biological systems, but they are counter examples.
Not sure those example really support your point. Salt mixed with water is not the lower level of entropy but the more complex. Now should the salt and water independently decide to mix and create the solution then that would support your point.
Or a zoo.
Or a farm.
“Of the star systems weve explored so far, 100% have life. Extrapolating this, there are approximately 400 billion civilizations in the Milky Way galaxy.”
LOL reminds me of COVID numbers on any side of that argument.
