Aliens can move the planets of the solar system, astronomers say
Planetary scientist Matthew Clement of the Carnegie Institution’s Earth and Planetary Laboratory and colleagues claim that aliens can alert us to their presence by moving the planets around, reports inverse.com.
Experts say that an alien civilization can organize entire solar systems of planets. They can also bombard moons and planets with asteroids to change their orbits and signify their presence, planetologists say.
According to astronomer Matthew Clement, this ambitious planetary shuffling will provide an opportunity for aliens to advertise their presence to us.
In a recent article in the Monthly Notices of the Royal Astronomical Society, Clement and his colleagues suggest that a sufficiently powerful and motivated alien civilization could create entire solar systems with planets.
Planetologists believe that this could be done with an object the size of an asteroid. To do this, it will be enough to direct it to the correct course in order to influence other planets with gravitational shocks, gradually moving them to different orbits.
“This actually happens,” Clement tells Inverse. “We are fairly confident that the Solar System’s giant planets moved around significantly after they formed, as they had repeated flybys with leftover debris and with stuff like Pluto.”
Scientists believe that doing such a thing is not entirely out of the realm of science fiction. Clement says there’s already serious speculation about using gravitational nudges from another small object to steer an asteroid into a closer orbit for mining.
And already now we are using the same principle to launch spacecraft into more distant orbits (or send them flying outside the solar system).
“It would take millions of years to have one asteroid, or a number of asteroids move a planet-sized thing that [necessary] amount of distance,” says Clement. That’s an order of magnitude longer than our species has even existed.
“But if you’re a more advanced civilization, maybe you could think on million-year timescales.”
A technologically advanced alien culture might find a way to apply gravity to an entire planet to change its orbit.
While it’s hard for us to imagine how to do that, Clement says that in terms of clean energy needs, any civilization tech-savvy enough to harness most or all of their star’s energy could do so in just over two (Earth) years.
“It is worth considering that any civilization can only broadcast itself for a short period of time,” says Clement.
Some technologies may outlive their creators – for example, our radio transmissions will propagate into space long after we’re gone, and Lageos satellites (a pair of laser reflectors in very stable orbits 5,900 kilometers above Earth) are likely to stay in orbit longer than The earth will remain habitable.
Alien space debris stuck in Earth’s orbit, researchers say
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.
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.
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
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.
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.
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 is acting strange again
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
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.
