Is it strange we have not heard or seen another civilization yet? Well according to this article that make sense if these advanced civilizations are picky on where they setup camp. In the article provided by interestingengineering.com and written by Ameya Paleja points this out wonderfully.
"Could this be the reason why we haven't spotted them yet?
Believers in the Drake Equation may have found just the right explanation for why alien civilizations haven't been spotted by humanity yet. A new study published by U.S.-based researchers states that alien civilizations are likely looking for particular types of stars when trying to establish an intra-galactic base, and our Sun simply does not meet their criterion, Universe Today reported.
In the year 1950, Enrico Fermi and Michael Hart pointed out the huge gap in the application of the Drake Equation, the estimation of the number of civilizations in our galaxy. While the Drake Equation suggests a high mathematical probability for the existence of advanced alien civilizations, Fermi and Hart wondered why hadn't we spotted one yet. This was dubbed the Fermi Paradox.
SETI does not make sense
Years later, Hart published a detailed paper further analyzing the Paradox wherein he stated that civilizations could rapidly expand through a galaxy by sending out ships to the nearest 100 stars who would then repeat the process, enabling galaxy-wide expansion in a short period of time.
According to hart's calculations, our galaxy could be traversed in just 650,000 years, and an advanced civilization would have made contact with humanity by now. Since there haven't been any, Hart concluded there are no alien civilizations out there, and therefore, missions like Search for Extra-Terrestrial Intelligence (SETI) do not make sense.
The American astrophysicist also went on to state that if there was ever any attempt to colonize our Solar system, it would be by our descendants,
But what if the Sun isn't exciting?
In a paper that has recently been accepted by the Astrophysical Journal for publication, authors, Jacob Haqq-Misra and Thomas Fauchez from the Blue Marble Space Institute of Science and American University, respectively, point out flaws in the Fermi Paradox itself.
The authors state that since all stars in the galaxy are not the same, it makes sense if alien civilizations are a bit picky about where they would like to put up their colonies. Another study in 2021, had suggested that long-lived civilizations would rather pick the low-mass K and M-dwarf star systems to maximize their longevity in the galaxy.
Both K and M-dwarf stars are long-lived stars when compared to a yellow dwarf like our Sun. While this might not make a huge difference to humans, authors suggest that alien civilizations capable of colonizing solar systems would definitely take this into consideration while making their decisions.
Irrespective of the advanced stage of civilization, an attempt at colonizing a solar system would still involve the dedication of lots of resources, and civilization would not bet its resources on a star that would die out sooner, even if it meant by a few million years.
According to the researchers' estimates, an advanced civilization could take about two billion years to reach all low-mass stars, and there could be multiple civilizations attempting this right now in our own galaxy, something we can't write off just because we haven't spotted them. Programs like SETI could help us in this endeavor to spot them.
In our lifetimes, we would definitely not be able to replicate their success, but that does not mean we should not look for their signs either.
The paper was published in the Quarterly Journal of the Royal Astronomical Society.
Abstract:
An expanding civilization could rapidly spread through the galaxy, so the absence of extraterrestrial settlement in the solar system implies that such expansionist civilizations do not exist. This argument, often referred to as the Fermi paradox, typically assumes that expansion would proceed uniformly through the galaxy, but not all stellar types may be equally useful for a long-lived civilization. We suggest that low-mass stars, and K-dwarf stars in particular, would be ideal migration locations for civilizations that originate in a G-dwarf system. We use a modified form of the Drake Equation to show that expansion across all low-mass stars could be accomplished in 2 Gyr, which includes waiting time between expansion waves to allow for a close approach of a suitable destination star. This would require interstellar travel capabilities of no more than ∼0.3 ly to settle all M-dwarfs and ∼2 ly to settle all K-dwarfs. Even more rapid expansion could occur within 2 Myr, with travel requirements of ∼10 ly to settle all M-dwarfs and ∼50 ly to settle all K-dwarfs. The search for technosignatures in exoplanetary systems can help to place constraints on the presence of such a "low-mass Galactic Club" in the galaxy today."
So if smaller stars are a preference then it stands to reason we have been looking in the wrong places. In any event what do you believe about other civilizations in our universe?

I have lost a lot of faith with the Medical Community and the Governments over the last several years, but there are a few good things that can raise above the corruption and the pushing of drugs a new approach to heal people. The following is from www.gaia.com and written by Hunter Parsons that does not involve any drug or pushing an ineffective so called vaccine that the drug company is not held accountable in any way but they use sound! The use of sound can regrow bone tissue! Here is the story:
"The future of regenerative medicine could be found within sound healing by regrowing bone cells with sound waves.
The use of sound as a healing modality has an ancient tradition all over the world. The ancient Greeks used sound to cure mental disorders; Australian Aborigines reportedly use the didgeridoo to heal; and Tibetan or Himalayan singing bowls were, and still are, used for spiritual healing ceremonies.
Recently, a study showed an hour-long sound bowl meditation reduced anger, fatigue, anxiety, and ...
Not a fan of a Defense Agency studying Anti-Gravity and other Exotic Tech, but if the commercial world and make this technology cheap that will change our world yet again. The following is about three minute read and from www.gaia.com. The below was written by Hunter Parsons:
"Wormholes, invisibility cloaks, and anti-gravity — it’s not science fiction, it’s just some of the exotic things the U.S. government has been researching.
A massive document dump by the Defense Intelligence Agency shows some of the wild research projects the United States government was, at least, funding through the Advanced Aerospace Threat Identification Program known as AATIP.
And another lesser-known entity called the Advanced Aerospace Weapons System Application Program or AAWSAP
The Defense Intelligence Agency has recently released a large number of documents to different news outlets and individuals who have filed Freedom of Information Act requests.
Of particular interest are some 1,600 pages released to Vice News, which ...
As our technology gets better we are discovering more about the history of mankind and pushing the timeline back further and further. The following article is from www.gaia.com and written by Michael Chary that discusses this new find that changes the historical timeline:
"Over the past decade, there have been a number of archeological revelations pushing back the timeline of human evolution and our ancient ancestors’ various diasporas. Initially, these discoveries elicit some resistance as archeologists bemoan the daunting prospect of rewriting the history books, though once enough evidence is presented to established institutions, a new chronology becomes accepted.
But this really only pertains to the era of human development that predates civilization — the epochs of our past in which we were merely hunter-gatherers and nomads roaming the savannahs. Try challenging the consensus timeline of human civilization and it’s likely you’ll be met with derision and rigidity.
Conversely, someone of an alternative...
Not sure if you have heard of a show on YouTube called "The Why Files". If not you should check it out it is interesting and has some humor with it on different subjects. Last weeks was on a different theory how the Universe works and how main stream Science is attempting to shut it down like is always seems to do if it goes aguest some special interest. Today it is akin to what happened to those who questioned the Earth was the Center of the Universe that main stream so called Science all believed during the Renaissance period, They called any theory that the Earth was not the Center of the Universe misinformation. Does this sound familiar today? People laughed and mocked people like Leonardo da Vinci, Nicolaus Copernicus, Georg Purbach as crack-pots, conspiracy theorists, nut-jobs and they were suppressed and even imprisoned for their radical thoughts and observations. Again it sounds like today in so many ways. In any event this is a good one to ponder and see even if a bad idea ...
Seemingly chaotic systems like the weather and the financial markets are governed by the laws of chaos theory.
We all have heard about chaos theory, but if you have not or have forgotten what chaos theory is well here you go from interestingengineering.com:
"Chaos theory deals with dynamic systems, which are highly sensitive to initial conditions, making it almost impossible to track the resulting unpredictable behavior. Chaos theory seeks to find patterns in systems that appear random, such as weather, fluid turbulence, and the stock market.
Since the smallest of changes can lead to vastly different outcomes, the long-term behavior of chaotic systems is difficult to predict despite their inherently deterministic nature.
As Edward Lorenz, who first proposed what became commonly known as the Butterfly Effect, eloquently said, "Chaos: When the present determines the future, but the approximate present does not approximately determine the future.""
You may have heard the term about chaos theory as a butterfly flaps its wings in Brazil,...
I for one have lost trust in Medical Doctors due to COVID and reflection that they seem to push pills for everything and untested so called vaccines that is using a unproven technology because the Government and the Medical Boards of the State told them to. There are a very few exceptions. Thus they do not address the key problem just prescribe more and more pills to keep you alive an sick longer for them and Big Phama to profit from you. Will AI do any better? Well that depends on what was used for the training of AI. If it also pushes pills and vaccines without question then you have the same problems noted above. However, if the AI Training includes all possible forms of treatment and they zero in on the right issues for the true problem then there is possibilities they would be way better than most of the current Medical Doctors today.
The following is from an article from interestingengineering.com and written by Paul Ratner:
