Harvard physicist: Earth should sign an interstellar treaty with alien civilizations to prevent cosmic catastrophe

Published

(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.

Earth-like world covered by raging volcanoes found in space

Published

Scientists at the University of California have discovered a planet
that may bear a resemblance to Earth. However, unlike our planet, this
peaceful planet is covered with fierce volcanoes. News of the discovery
was published in the journal Nature.

The new planet was discovered using the Kepler telescope, which
explores outer space in search of exoplanets. According to scientists,
the planet is in the life zone of its star and may have conditions for
the development of life.

However, the presence of volcanoes on the surface of this planet may
mean that it is not suitable for life. This is due to the fact that
volcanoes can emit gases into the atmosphere, which can be poisonous to
living organisms.

On the other hand, scientists believe that the presence of volcanoes
on this planet may mean there is a magnetic field that protects it from
harmful cosmic rays. This may be one of the factors contributing to the
development of life on this planet.

Although the planet is 110 light years away from Earth, scientists
hope that it could be the subject of future research. However, this will
require new telescopes and more accurate measurement methods.

Interestingly, the search for exoplanets is one of the hottest topics
in modern astronomy. Scientists around the world are looking for
planets that may have conditions for the development of life. Some of
these planets are only a few light years away from Earth.

In addition, there is a theory that life on Earth may have originated
through volcanic activity. Volcanoes may have created the conditions
for the formation of the first organic compounds, which then led to the
emergence of life.

Asteroid 1994 XD: Threat to Earth or opportunity for space exploration?

Published

By

On June 12, 2023, the asteroid 1994 XD, which is over 500 meters in
diameter, will approach Earth. Despite the fact that it will be 3.1
million kilometers away, which is 8 times the average distance to the
Moon, many are asking – can this asteroid become a threat to our planet?

It is worth noting that asteroids, like comets, pose a threat to the
Earth, but the probability of collision with them is very low. In
addition, there are many programs and projects to track space bodies,
which allow you to identify a potential threat in time and take measures
to prevent it.

However, asteroids are also of interest to scientists and space
research. Studying the composition and structure of these bodies can
help scientists better understand the origin of the solar system and the
possibilities for life in space.

For example, asteroids may contain water and other elements necessary
for life, which could be used to build space stations and bases on
other planets. In addition, studying asteroids can help scientists
develop methods to defend against potential threats from space.

The asteroid 1994 XD was discovered in 1994 by the Kitt Peak
Observatory and has not posed a threat to Earth since then. Its close
approach to our planet will be an opportunity to study this cosmic body
in more detail and expand our knowledge of space.
