That’s some serious climate change!
So is this a thinly veiled reference to Robert Reichhhhhhhhhh?
Best candidates are those orbiting G2V stars, like our own.
Many are within 300 light years.
With an estimated average distance of 10 billion light years between galaxies, if there were only one intelligent species per galaxy, they would only likely have a chance of meeting if their respective galaxies got close enough to collide.
We can probably test that hypothesis in about 4 billion years when the Milky Way and Andromeda galaxies are expected to collide (Better check whether your car and homeowner insurance policies cover such galactic collisions.)
This story is BS.
...
That’s very convincing. /s
I said guess, not bet.
And I do have the Fermi Paradox on my side.
To anyone who says I’m wrong I say:
Show me the aliens!
Similarly Frank Tipler limited his claim, "Extraterrestrial intelligent beings do not exist" (Royal Astronomical Society, Quarterly Journal, Vol. 21, Sept. 1980, p. 267-281) to the Milky Way galaxy.
An answer to the question of whether the Milky Way galaxy is the only one with extraterrestrial intelligent beings will include the same factors which likely limit the number of Milky Way planets with intelligent beings to approximately one.
In addition there are also the other factors, such as whether there are unique galactic features necessary for intelligent life (regardless of whether they have the capability of intergalactic travel) to exist within that galaxy, which are only found in such special galaxies as the Milky Way, e.g., the size and shape of the galaxy, the size and activity of the galactic center black hole, the abundance and distribution of other black holes within the galaxy, the frequency of collisions with other galaxies, the amount of dark matter present.

I said that my QUESS is: one human-level-intelligence per galaxy, on average.
It would explain why our galaxy so far is generating questions like the Fermi Paradox... because WE are the one intelligence in THIS galaxy.
Just my opinion, of course. But I am ever-interested in this issue and always enjoy discussing it.
With regard to red dwarf stars, my GUESS is that almost none of them harbor much in terms of complicated evolution, but I PREDICT that those intelligences (hopefully we are one of them) that do achieve star travel will end up colonizing planets around red dwarf stars, for the simple reason that those are the stars that will still be around — and still be pumping out heat and light — HUNDREDS of billions of years from now.
But did she destory it or just brighten it up?
No one has claimed you said or ask the question which I had raised and then commented on.
Regarding your comment that intelligent beings “will end up colonizing planets around red dwarf stars,” such planets would not have an Earth-like natural environment, although domed communities could be built with an artificial environment.
Another possibility is that a sufficiently advanced intelligence could build a Dyson sphere around the red dwarf, to harness practically all of the energy emitted by that sun for providing environmental conditions in which to live.
I thought this was going to be a movie about why white males should leave the planet...
sorry, carry on.
I think you are right, there is nothing intelligent out there. (Sometimes, that includes us.)
I like the idea of Dyson swarms better than Dyson spheres. Think of the stress on the sphere material as you get closer and closer to the poles. Seems like a pretty difficult engineering problem, even for future engineering gurus.
But anyway, your point is well taken. Swarm or sphere, lock in most or all of the red dwarf energy and have a completely-enclosed domed world outside the orbit of the swarm/sphere.
This assumption, if I'm not mistaken, implies that in an infinite universe of galaxies, each having a Gazillion stars, with every star having a 1 in a Gazillion chance of harboring life, 1/e of all galaxies will have no life, and likewise 1/e galaxies will have 1 star harboring life, with the remainder having 2 or more stars harboring life, including 3 in 1000 having 5 such stars, and 1 in 10000 having 7 ... all based on the Poisson distribution.
