Aliens Would Not Attack Us: Is Humanity The Hostile Civilization?
Contrary to what many believe, it is the humans who would end up attacking an alien species, and not the other way around. This has been revealed by the science, technology and travel journalist Jamie Carter.
Some researchers claim that the behavior shown by humans towards other humans and nature shows that we are a hostile species. Therefore, they believe that in the future, if extraterrestrial contact is possible, it is more likely that humanity will be the first to attack.
The author of the article Jamie Carter, proposes a vision that almost nobody has considered; there is more chance of humans attacking an extraterrestrial civilization than the opposite.
Should we send messages into space in an attempt to contact advanced extraterrestrial civilizations? Or, maybe we should be afraid of being attacked?
These 2 questions are often contradictory, but most of the time we miss something important. It is likely that we are the “hostile aliens”.
Carter contacted Alberto Caballero, author of an experimental article to learn more about this version. His work determines how many dangerous alien civilizations might exist and how likely they are to invade us.
The number is staggeringly small. Extrapolating data on the history of invasions in the world in the last century, the military capacity of the countries involved and the global growth rate of energy consumption … there is a 0.0014% chance that the Earth will be invaded by a technologically advanced civilization.
This figure is based on the fact that the more advanced a civilization is, the less likely it is to attack again. After all, energy consumption is the method used to divide civilizations on the Kardashev Scale .
The Kardashev Scale and why they wouldn’t attack us
On this scale we can see Type I civilizations: those capable of harnessing the main sources of energy on their planet. Including the energy coming from its star.
Type II civilizations are capable of storing all the energy released from their star. Most likely through the Dyson Spheres . Its energy consumption is 10 orders of magnitude higher compared to that of a Type I civilization.
Finally, the Type 3 civilization, capable of accessing and controlling much of the energy generated by the entire galaxy.
Wait. Why would technologically advanced Type 1/Type 2 civilizations that consume more energy be less likely to invade?
“Data from last century shows that the frequency of invasions between countries have gradually decreased as time goes by,” said Caballero.
“Based on that data a civilization like humanity would be more likely to invade than a Type-1 civilization, but they would not have the means to travel to an extraterrestrial planet.”
Caballero also thinks there haven’t been any studies that estimate the prevalence of malicious civilizations or the probability of extraterrestrial invasion, hence his own effort. “It has not been possible to contrast the potential benefits versus the risks of sending a serious message,” he said.
There will be no aliens attacking each other, at least for now. So why the fear about attempts to make contact (known as messaging extraterrestrial intelligence or METI)?
“For the general public, the fear probably comes from all the decades of Hollywood movies about alien invasions,” said Caballero. Only in a very few movies – such as 2016’s Arrival – are extraterrestrial invaders peaceful.
In other words … calm down, look up, and think about something you might want to say to another intelligent civilization thousands of light-years distant.

Recently, a group of experts from Harvard University, led by physics
professor Avi Loeb, announced the possible presence of alien space
debris in Earth’s orbit, reports the Daily Star.
Leading
space research expert Professor Loeb is confident that the discovery of
such “interstellar objects could help expand our knowledge of possible
alien civilizations and technologies. A team of scientists is conducting
research to confirm that some of the objects in our orbit may be
connected to other star systems.
During an interview with Live
Science, Professor Loeb explained that these objects could enter the
solar system from interstellar space, defying Jupiter’s gravitational
pull and occupying limited orbits around the sun.
Some of them may
have technological origins similar to the probes sent by mankind into
interstellar space, such as Voyager 1 and Voyager 2, Pioneer 10 and 11
and New Horizons.
However,
despite these interesting assumptions, Professor Loeb did not specify
what specific objects he was talking about. In his research report, he
notes that there could be “a significant number” of potentially
detectable objects in Earth’s orbit.
To confirm their assumptions,
the team of scientists uses computer simulations and the Vera Rubin
Observatory (Chile) with a high-resolution camera of 3.2 billion pixels.
This will allow for regular observations of the Southern sky and the
possibility of detecting several captured objects about the size of a
football field.
It is assumed that these interstellar objects passed through the
boundaries of the solar system and may carry unique information about
other civilizations and their technologies. If we could confirm the
origin of these objects, the mysteries that open before us, this would
be a real breakthrough in space exploration.
Professor Loeb
expresses hope that the new research will not only help expand our
knowledge of extraterrestrial technologies, but may also lead to the
discovery of new alien civilizations . Answers to such questions can be
of global significance and influence our understanding of the place of
mankind in the Universe.
And
while there are still many questions and assumptions, the study by
Professor Loeb and his team opens a new chapter in space exploration.
Each new discovery can be the key to deciphering the mysteries of the
cosmos and the possibility of encountering alien life forms.
Betelgeuse, a red giant on the brink of death, continues to show
unusual behavior. After the Great Blackout, which occurred in late 2019
and early 2020, the star became unusually bright. It is now the seventh
brightest star in the sky, while it normally ranks tenth. This has led
to speculation that Betelgeuse is preparing to explode in a
spectacularly large supernova.
However, scientists believe it’s too early to tell, and it’s likely
that this behavior is due to ongoing fluctuations after the Great
Blackout of 2019, and the star will return to normal within a decade.
Betelgeuse is one of the most interesting stars in the sky. It is
about 700 light-years from Earth and is a red giant in the last stage of
its life. It is also an unusual star for a red giant because it was
previously a monster blue-white O-type star, the most massive class of
stars.
Betelgeuse has changed its spectral type because it has almost
exhausted its hydrogen reserves. It now burns helium into carbon and
oxygen and has expanded to a gigantic size: about 764 times the size of
the Sun and about 16.5 to 19 times its mass.
Eventually it will run out of fuel to burn, become a supernova, eject
its outer material, and its core will collapse into a neutron star.
Before the Great Blackout, Betelgeuse also had periodic fluctuations
in brightness. The longest of these cycles is about 5.9 years and the
other is 400 days. But it seems that the Great Blackout caused changes
in these oscillations.
A new paper by astrophysicist Morgan McLeod of the
Harvard-Smithsonian Center for Astrophysics has shown that the 400-day
cycle appears to have been halved. This pulsational cycle is probably
caused by expansion and contraction within the star. According to
simulations carried out by MacLeod and his colleagues, the convective
flow inside Betelgeuse may have risen and become material that separates
from the star.
