The Milky Way galaxy has approx. 100,000,000,000 stars and it's 1 of approx. 1,000,000,000 or so galaxies. So this nitwit is ready to conclude there are no more "earths" after a very crude form of investigation of 110 planets around 25 or so stars that at this point can ONLY, ONLY detect Jupiter-sized planets.
Utter rubbish from a pseudo-scientist who had to work hard to find something to write about.
There is only one data point. And that is us. All else is speculation. However, using probability, we can make some predictions. Thusly was born the "Drake Equation".
the book was
"the rare earth"
written by brownlee and another u of wash prof
an amazing book.
They go thru all the arguments why complex life is so rare. This is my solution to fermi's paradox.
Why is this surprising? If we're using gravitational anomolies to detect planets, of course it's going to be easier to find large planets that are close to their sun, because the effects of gravity are much greater.
Drake equation ping. I always go back and forth on this ....
When there are billions of stars in each galaxy, and billions of galaxies, it's kinda hard to believe we're unique.

Well said.
Jupiter is not habitable: it is too cold, and is mostly composed of dense gas. And it is unlikely that extrasolar giant planets would support life either.
This type of thinking always amazes me. Yes, life that evolved on Earth has adapted to the conditions found on Earth, no surprise here. Would it be so surprising that life elsewhere in the universe would adapt to the conditions there?

We've been over all this time and again on FR. Current detection methods select a highly specific (and probably highly unusual) sample which tells us little about Earth-like (or even Jupiter-like) worlds.
The idea that these close binary brown dwarf systems formed differently from our solar system in no way supports the title of this article, even if the idea is perfectly correct.

What is your opinion of the arguments made in "Rare Earth". The Drake equation only gives the upside, but doesn't seem to take into account the conditions that would preclude higher forms of life. For instance, the radiation conditions in the core of galaxies and in the arms of spiral galaxies are too high to allow the survival of higher life forms. That leaves the area between the arms for habitable zones in spiral galaxies, and stars only stay in between the spiral arms for extended periods of time if they are 1/2 the radius of the galaxy from the center of the galaxy. These factors alone remove several orders of magnitude from the number of possible stars that could sustain higher forms of life.
This seems too easy but "In the beginning God created the heavens (plural) and the earth (singular)"
IIRC, they have a common ancestor Tümuch Beer...
I thought our planets' orbits were "wildly elliptical."
Ding Ding Ding! We have a winner!
It's called a "selection effect" - the data sample looks biased towards hot Jupiters, but that's only because current detection technologies find those preferentially. Give it about 10 years and we will have much better data with the new surveys coming on line. Anyway, personally I find it amazing that we now know of 10 times as many planets OUTSIDE our solar system as IN it!
