3) if it’s serious about spreading widely, then it “maxes out” the technology with which to do so, approaching the limits set by physical law.

In cases 1 or 2, the civilization will of course be hard for us to detect, unless it happens to be close by. But what about case 3? There, Robin says, the “civilization” should look from the outside like a sphere expanding at nearly the speed of light, transforming everything in its path.

Don't have to have loaded a Jew into an oven to be a Nazi, just marginalize their existence like a good lil' sympathizer and it makes you one!

Presto Chango, you're a Derango!

I don't mean to speak for anybody else who's posted in this thread, so speak up if I'm wrong, but I think the point is that there is a near nil chance that any civilization would become so technologically advanced that they could safely engage in interstellar travel yet manage not to have already suffered an extinction level event... either by their own hands or a fluke accident.

The Earth is 4.5 billion years old and the Universe 13.8. That means there could be other civilizations out there billions of years older than ours. My bet is there is. Thank god the verse is full of what they need so they can ignore us.

Like I said before, I'm not saying that there isn't life on other planets. Statistically speaking the chances that there aren't are almost nil.

But the chances that a civilization can evolve to the point of having technology that allows them to travel to other inhabited planets before they destroy themselves is also just about as small.



As for your cartoon above, it's the first one I've appreciated that you've posted.

I do get a laugh when we claim to have been the first to make something fly on Mars. Maybe a billion years ago there were helicopters all over mars like there is on Earth today.

But we know it all.

Imagine the hypocrisy of a government who will allow businesses to card people to get a job or buy groceries, but won't card people to vote in elections and gives millions of non-citizens free money from taxpayers.

No, but I really enjoyed the book Jesus on Mars by Philip José Farmer.


What does Hoagland have to say?

To cut to the chase, Robin is trying to explain the famous Fermi Paradox: why, after 60+ years of looking, and despite the periodic excitement around Tabby’s star and ‘Oumuamua and the like, have we not seen a single undisputed sign of an extraterrestrial civilization? Why all this nothing, even though the observable universe is vast, even though (as we now know) organic molecules and planets in Goldilocks zones are everywhere, and even though there have been billions of years for aliens someplace to get a technological head start on us, expanding across a galaxy to the point where they’re easily seen?

Robin proposes, plausibly I think, that if you give a technological civilization 10 million or so years — i.e., an eyeblink on cosmological timescales — then either

1) the civilization wipes itself out, or else

2) it reaches some relatively quiet steady state, or else

3) if it’s serious about spreading widely, then it “maxes out” the technology with which to do so, approaching the limits set by physical law.

In cases 1 or 2, the civilization will of course be hard for us to detect, unless it happens to be close by. But what about case 3? There, Robin says, the “civilization” should look from the outside like a sphere expanding at nearly the speed of light, transforming everything in its path.

You so smart.
Terra = Earth. 3rd Planet orbiting Sol. 3rd Rock From the Sun.

Extraterrestrial = Not From Earth.

So you conjure that Aliens must think that Earth-bound Humans are Not From Earth.
You such a genius.

And you are so dumb. What you suggest is that there is no comparable concept in our entire Universe. How you would you know this?

I would add; check out the multi verse theory, string theory. You’ll learn Astrophysicists believe it is possible Terra = Earth may exist in many other dimensions. You should be embarrassed by your unenlightened post rappy.

Planetary scientists suggest a solution to the Fermi paradox: Superlinear scaling leading to a singularity

They began by studying how human civilizations rose and fell throughout history. Next, they studied the history of large cities, and there, too, they noticed that most grew to a certain point and then collapsed. They developed a hypothesis that suggested such rising and falling by alien space civilizations would lead to one of two scenarios. In the first, the civilization would come to realize they were growing too large and would cease traveling to or colonizing other worlds. In the second, they would not recognize their folly and would therefore collapse. From our perspective, both scenarios would have the same outcome—the aliens would not visit us, or even demonstrate evidence of their existence. The distance from them to us would be too far.

The researchers describe their hypothesis as superlinear scaling—where a civilization grows exponentially, colonizing other worlds until they became unable to sustain the energy demands of their constant encroachment. Eventually, if they did not take action, they would reach a singularity—a point of no return, at which they could not save their civilization from collapse. They note that were it not for the vast distances involved, we would likely easily spot evidence of an alien civilization on the point of collapse because it would be emitting enormous amounts of energy.
