Harvard physicist: Earth should sign an interstellar treaty with alien civilizations to prevent cosmic catastrophe
(Planet Today) Harvard University astrophysicist Abraham Loeb recommends establishing an interstellar treaty with advanced alien civilizations that may be residing in the Milky Way and the neighboring galaxy, Andromeda. He says that this treaty would prevent a cosmic catastrophe that can wipe out the Earth.

Loeb, who was the longest-serving chair of Harvard’s Department of Astronomy, made the suggestion in an article published May 23 in the Scientific American. He opened his article with a warning that highly advanced alien civilizations might have the capacity to build a particle accelerator as wide as our solar system. This gigantic particle accelerator would collide electrons at the Planck energy, the scale where gravity must be described quantum mechanically.
If activated, the particle smasher could create a “soap bubble” of dark energy that would expand and disintegrate anything in the path of its detonation wave. This wave would travel through space at the speed of light and unleash a massive amount of energy that could destroy the Earth.
“The bad news is that we would not receive any advance warning before this cosmic disaster hit us in the face because no precursor signal can move faster than light to alert us to the risk,” Loeb wrote. He added that the powerful wave would wipe out all organisms on the planet in the same way that the Chicxulub impactor wiped out the dinosaurs 66 million years ago: “We would never know what hit us.”
The astrophysicist suggested establishing what he called the “Planck Collider Treaty” to prevent anyone from building a destructive particle accelerator. It would be similar to the Partial Nuclear Test Ban Treaty, signed in 1963 by the United States, United Kingdom and the Soviet Union. This treaty banned the testing of nuclear weapons in the Earth’s atmosphere, in outer space or underwater.
Loeb said that without the Planck Collider Treaty, humanity could only hope that highly advanced civilizations would behave responsibly. He added that humanity only has to sign an agreement with other civilizations that might be existing in Milky Way and Andromeda.
“[It] does not extend beyond the Local Group of galaxies,” he said, referring to the group of 54 or so galaxies to which the Milky Way belongs. “Even without a treaty signed or honored on extended intergalactic scales, the accelerated expansion of the universe will ultimately save us from the risk of a Planck collider catastrophe.”
He explained that all galaxies outside of “Milkomeda” – the result of the eventual merger between Milky Way and Andromeda – will eventually move away at superluminal speeds. Once they reach a boundary called the cosmic event horizon, nothing happening could affect the Earth.
“The accelerated cosmic expansion will carry away from us all the risky Planck colliders within distant galaxies, ultimately protecting us from any mishaps in them,” he said. “This constitutes yet another example of Mother Nature being kind to us.”
Interstellar object could be evidence of alien civilizations
In a book titled “Extraterrestrial: The First Sign of Intelligent Life Beyond Earth,” published early this year, Loeb argued that the interstellar object ‘Oumuamua was a discarded piece of alien technology that was powered by sunlight.
‘Oumuamua, which was the first known object to visit our solar system, mystified scientists when it was discovered in 2017 because it accelerated and deviated from its predicted trajectory. This could have been easily explained if ‘Oumuamua were a comet expelling gas and debris. But it did not display a comet’s tail or any other visible evidence of this outgassing.
‘Oumuamua was never photographed up-close during its brief visit – scientists learned of its existence when it was already on its way out of our solar system. This left a lot of unanswered questions as to its shape and other properties.
Loeb’s theory was that the interstellar visitor was a light sail – a spacecraft powered by sunlight – owned by a highly advanced extraterrestrial civilization. This could explain why the object accelerated, he said.

An organization of civilian volunteers dedicated to the study of
unidentified flying objects (UFOs) has issued a statement based on
decades of studying eyewitness reports. According to Mutual UFO Network,
“alien bases” may be hiding off the coast of Alaska, reports the-sun.com.
Researchers
say the deep waters in this region may hold something surprising. After
analyzing reports from the ship’s crew from 1945, they hypothesized
that alien objects could be lurking underwater, off the coast of the
state.
Alleged sightings of alien spacecraft nearly 80 years ago
have become a key point in research. Members of the organization believe
that UFOs move over water and may have “bases.”
Researchers
allege crew members on a U.S. Army transporter ship sailing past Island
Adak saw a massive UFO sized 150 to 200 feet emerge from the water.
Although these reports are nowhere to be found, UFO enthusiasts believe
the unidentified flying vehicles likely were used to commute to
different supposed alien bases hiding in the deep waters.
As
the “secret reports” of the sailors aren’t available, investigators
have taken it upon themselves to unravel the mystery surrounding the
unidentified flying objects and they believe the ocean has alien bases
that humans aren’t aware of.
Enthusiasts claim that UFOs may be
using “underwater networks” or wormholes as superhighways to travel
between points in the universe. UFO researcher Johnny Enoch added that
such objects could serve as a vehicle for aliens.
There are also
theories that other places on Earth could serve as bases for alien life.
A mountain in Seoul, South Korea is believed to be hiding a UFO,
according to Dr. Steven Greer.
An episode of the series “The
Alaska Triangle” features satellite imagery that claims to show one of
the “alien bases” in the Pacific Ocean off the coast of California.
Meanwhile,
another researcher featured in the program showed markings from the sea
bed that she claimed could have been roadways for aliens.
While
the mysteries of the ocean remain unsolved, researchers continue their
search, trying to unravel the mystery of what may be hiding in the
depths of the waters off the coast of Alaska.
A volcanic comet the size of a mid-sized US city has
violently exploded for the second time in four months as it continues
racing toward the earth. And following the massive eruption, the cloud
of ice and gas sprouted what looked like a pair of gigantic devil horns.
The city-sized comet, named 12P/Pons-Brooks, is a cryovolcanic — or
cold volcano — comet. It has a solid nucleus, with an estimated diameter
of 18.6 miles, and is filled with a mix of ice, dust and gas known as
cryomagma. The nucleus is surrounded by a fuzzy cloud of gas called a
coma, which leaks out of the comet’s interior.
When solar radiation heats the comet’s insides, the pressure builds up
and the comet violently explodes, ejaculating its ice-cold innards into
space through seeping cracks in the nucleus’s shell.
Live Science report:
On Oct. 5, astronomers detected a large outburst from 12P, after the
comet became dozens of times brighter due to the extra light reflecting
from its expanded coma, according to the British Astronomical Association (BAA), which has been closely monitoring the comet
Over the next few days, the comet’s coma expanded further and developed its “peculiar horns,” Spaceweather.com
reported. Some experts joked that the irregular shape of the coma also
makes the comet look like a science fiction spaceship, such as the
Millennium Falcon from Star Wars.
The unusual shape of the comet’s coma is likely due to an irregularity in the shape of 12P’s nucleus, Richard Miles, a BAA astronomer, told Live Science after the comet’s previous eruption.
The outflowing gas is likely being partially obstructed by a notch
sticking out on the nucleus, Miles said. As the gas continues to expand
away from the comet, the irregularity in the coma’s shape becomes more
defined and noticeable, he added.
12P is currently hurtling toward the inner solar system, where it
will be slingshotted around the sun on its highly elliptical 71-year
orbit around our home star — similar to the green comet Nishimura, which
pulled off a near-identical maneuver on Sept. 17.
12P will reach its closest point to Earth on April 21, 2024, when it
may become visible to the naked eye before being catapulted back toward
the outer solar system. It will not return until 2095.
This is the second time 12P has sprouted its horns this year. On July
20, astronomers witnessed the comet blow its top for the first time in
69 years (mainly due to its outbursts being less frequent and harder to
spot during the rest of its orbit). On that occasion, 12P’s coma grew to
around 143,000 miles (230,000 km), which is around 7,000 times wider
than the comet’s nucleus.
It is unclear how large the coma grew during the most recent
eruption, but there are signs the outburst was “twice as intense” as the
previous one, the BAA noted. By now, the coma has likely shrunk back to
near its normal size.
As 12P continues to race toward the sun, there is a high probability
that we will witness several more major eruptions. It is possible that
those eruptions will be even bigger than the most recent one as the
comet soaks up more solar radiation, according to Spaceweather.com.
But 12P is not the only volcanic comet that astronomers are currently
monitoring: 29P/Schwassmann-Wachmann (29P) — the most volatile volcanic
comet in the solar system — has also had several noticeable eruptions
in the last year.
In December 2022, 29P experienced its largest eruption in around 12 years, which sprayed around 1 million tons of cryomagma into space. And in April this year, for the first time ever, scientists accurately predicted one of 29P’s eruptions before it actually happened, thanks to a slight increase in the comet’s brightness in the lead-up to the icy explosion.
