Today's Top Space Headline: "Alien Civilizations May Not Be Technologically Advanced"



"Perhaps Earth was lucky to see technology arise (in the spirit of the novel Origin by Dan Brown)," observes Avi Loeb, chair of the astronomy department at Harvard University, founding director of Harvard's Black Hole Initiative and director of the Institute for Theory and Computation at the Harvard-Smithsonian Center for Astrophysics. He also chairs the advisory board for the Breakthrough Starshot project. The image above shows the finale of the Cassini Mission spacecraft.

As we discover numerous habitable planets around other stars in the Milky Way galaxy, including the nearest star, Proxima Centauri, one cannot help but wonder why we have not yet detected evidence for an alien civilization. As the physicist Enrico Fermi asked, “Where is everybody?” Even though the first interstellar object to be discovered in the solar system, 'Oumuamua, had an unusually elongated shape as might be expected from an alien probe, it does not appear to maneuver and is radio-quiet below the level of a single cell phone.


True, a signal from an alien civilization might be subtle or sophisticated, but the disappointing silence of the sky may also indicate that long-lasting extrastellar civilizations do not use technologies that would make them visible to our telescopes, writes Loeb, in Scientific American

Based on our own experience, we expect that civilizations much older than ours will be scientifically savvy and hence technologically advanced. But it is also possible that a simpler lifestyle rather than scientific prosperity has dominated the political landscape on other planets, leading to old civilizations that are nevertheless technologically primitive.

Maybe, maybe, lots of maybe's. Give me some god damn aliens already.

"Alien Civilizations May Not Be Technologically Advanced"

Only speculation and maybe's, could be's, and might be's + numerous others..........Blah blah blah. Nobody cares about these redundant articles. There are no aliens and we will not discover any, ever, end of story.

The probality of life, intelligence and techology is certainly hogher than zero, othewise we wouldn´t be reading this article. Universe is just huge. I´m sure we are not theonly ones who won this lottery.


You must be a fucking idiot or religious to think in the entire universe with trillions of planets that earth is the only planet with life on it. Maybe you should retake some basic math classes.

"Advanced" has more than one meaning. Depending on the conditions under which exo life started and evolved, technologically "different" could be more appropriate.

@Rizla, a big place no doubt, but Earth is the only known planet to harbor an advanced intelligent life form in the universe to date. So there are no aliens, can you comprehend that?

Religion is for the weak minded and desperate.

There is zero evidence of alien life forms or proof they exist or not, the point is mute and will be debated forever.


Have you perused the entirety of the universe to come to the definitive conclusion there are no advanced alien civilizations out there? How the heck can you say that? Earth is the only known planet yes, that doesn't mean it'll be that way forever. If you can understand mathematical probability, then you wouldn't make such flippant statments as "advanced aliens don't exist".

The universe came into existence with a lot of hydrogen, a little helium, and a trace of lithium; every heavier element must be created in nuclear fusion inside of stars. This takes a while. Perhaps we're the first life form to arise within the middle-aged heavy-elements universe?

We know that there's lots of life in water on THIS planet; perhaps the water-covered planets are teeming with non-technological life that never discovered fire, or metallurgy.

And perhaps, all the other life-bearing planets are simply so incredibly far away that we haven't detected them yet?

Either we're the only ones here, or the universe is teeming with life waiting to be found. Either way, it's an amazing thought!

Once a level of organised societal development was reached, the rate of technological development for a culture, wherever it started on Earth, seems to have been identical.

Comparing the Americas to Eurasia, the cultures in both places followed an almost identical development line; from farming, to metallurgy, to cities, to building ziggurats, to developing pictographic pre-cuneiform/hieroglyphic-Luwian style writing, and making bronze from arsenical copper. This happened in exactly the same way, and speed, in both the old world, in Iran and Mesopotamia, and in the new world, in Peru and Mesoamerica.

From farming to smelting bronze took about 5000 years, in the old and new world, the same rate of development. But, the old world discovered farming 5,000 years before the new world did and therefore got started in developing all the key technologies first. So now, the civilisations of the old world control the planet. It's not that they developed faster, it's just that the old world got a 5,000 year head start.

So, let's conquer those uncivilised aliens bastards before they develop the technology to conquer us! Hurry!!

@ Rizla, just like I said in my comment above.

There is zero evidence of alien life forms or proof they exist or not, the point is mute and will be debated forever.

@ thunder

Maybe you should educate yourself on things like the James Webb telescope. It may not happen in our lifetimes but you really seem to be some kind of nostradamus with all your assertions about the future. Absence of evidence is not evidence of absence, especially at the scale of the universe, we may find evidence one day of microbes or maybe even advanced life. To say it'll be debated forever is moronic hubris. Go educate yourself.
