...the Harvard-Smithsonian Center for Astrophysics found that six percent of red dwarf stars have habitable, Earth-sized planets.


There could possibly be a lot of smeg heads out there.

The whole "rare Earth" thing never did make much sense to me. It operates completely on the assumption that our planet is the most typical example of a habitable world. One of these decades, we'll learn that Earth is actually an odd or extreme case, and that there are millions more that we should have seen sooner.

We have a confirmed sample size of one.

Until we find another, we have no clue how prevalent life really is in the universe.

I wish they wouldn't say that they found habitable planets. We don't know that yet. Size and distance from its star only tell part of the story.

This.

It's just a bunch of guesses based on radio signals. Some radio telescope detected a semi-regular pulse in a certain part of the spectrum from a certain part of the galaxy, and from there they just infer (guess) all this nonsense about habitable planets, liquid water, "the Goldilocks Zone", etc. All bullshiat.

...the Harvard-Smithsonian Center for Astroisphysics found that six percent of red dwarf stars have habitable, Earth-sized planets.

Then the  Harvard-Smithsonian Center for Astrophysics if staffed by idiots. We've found exactly one habitable planet ever. We're living on it. The rest is pure speculation.

Of course we have alien overlords, most of them run foreign corporations.

Can we apply our knowledge of what we know here to what we see out there? We haven't been to other planets in other solar systems, yet we assume gravity and chemistry operate the same and draw conclusions about the entire universe that way. Do you also feel uncomfortable about that?

Conclusions that are often wrong. How about some proof before we go off half cocked? 20 years ago if I told a you the universe is mostly made of matter we cannot see or measure you would have had a good mocking laugh.

This is why science makes a poor dogma. Its only true until its proven wrong.

Or Kryptonians, if you use the Media Astronomy definition of Earth-sized that means 'anything smaller than Neptune and bigger than the Moon'

Have you seen my unicorn? There have been sightings and descriptions of such a creature since antiquity. Surely this is evidence of its existence!

True, but theoretically, they're all "habitable."

Apparently there is some debate about whether habitable planets can exist in a system with a red dwarf store.  Apparently it has to due with the size and closeness of the potentially habitable zone and tidal lock.  The moon thing is interesting though

Correct. And they turned out to be ibexes, from the side.

Surely there is a difference between claiming a new kind of animal when you are surrounded by animals, and claiming it's magic when you've never seen magic?

Then, these questions will arise:

Are they friendly to us?

Do they have weapons of mass destruction?

Will they let us explore the stars?

Will they do business with us?

Will they convert to [insert religion]?

... Are they sexy?.

LOL really? You traveled back in time with Obama and heard it directly from each and every author.

The point is they really don't have enough information to make these kinds of grandiose proclamations.  Its all bullshait. Ask any statistician about his confidence in any model with a sample size of one.

But hey, the magic is real if you believe hard enough.

Our lesson for today: Thinking about the unknown is stupid.  We should only think about what we already know.  Because progress only happens when we stop contemplating what may be over the horizon.

Not really. This is not science. It is science fiction. Its dangerous because it carries the hallmarks of science but without the required rigor that makes it valid. Its "God might may done it" for the Star Trek set.

Wouldn't the probability of finding an Earth-like planet also depend on the metallic content of the star and the surrounding area?  You would need a certain percentage of metallic elements to have an Earth-like planet and given the studies on this topic, the earliest time that the metallic content of the Universe made Earth-like planets possible was about 4.6 billion years ago.

Any intelligent life must be able to manipulate its environment in some way, or else it would not require intelligence(absent the notion of a creative deity). While there may be some kind of extreme environment that requires manipulation of radiation to enable a non-mobile intelligence to evolve, the evolutionary requirement of manipulation most predictably dictates that an intelligence must be capable of motion. Motion, in turn, requires a chemical composition in biologics to be both solid and liquid and likely quasi-states between those two states of matter ("soft" solids like skin, "hard" liquids like mucus). This greatly cuts down on the number of biochemical combinations which are possible. Again, factor in probability - that is, the simplest chemical compositions most likely to survive - and you have a very strong argument for Earth being a typical example of a habitable world.

Nobodies saying exceptions are impossible, but we're just looking at statistics at this point.
