Unlock the secrets hidden inside the Earth with a strange metallic asteroid
The French writer Jules Verne in the 19th century fascinated readers
with the idea of traveling to the center of the Earth. Although Verne’s
tale was pure science fiction, scientists have long been attracted to
the mysteries of our planet’s deep interior. Extreme temperatures and
crushing pressure make it impossible to explore the Earth’s core
directly. However, there is hope to unlock these secrets with a
different approach – from space.
Planetary scientists believe that the best way to learn about Earth’s
interior is to study asteroids, especially metallic asteroids. These
asteroids are remnants of the early days of our solar system, when
planets were forming and colliding. Approximately 20% of asteroids are
composed of metal, similar to Earth’s core. By studying these metallic
asteroids, scientists hope to gain insight into what constitutes a
planetary core.
One such asteroid is Psyche, the largest known metallic asteroid.
Discovered in 1852, Psyche is comparable in width to Massachusetts and
is located in the main asteroid belt between Mars and Jupiter. Although
it can be observed in a backyard telescope, it appears to be nothing
more than a point of light.
“The Psyche mission provides a unique opportunity to directly study a
metallic asteroid and gain insight into Earth’s core. It could
revolutionize our understanding of planetary interiors.” – Dr. Sarah
Johnson, NASA planetary scientist
NASA realized the promise of studying Psyche and in early 2017
approved a $1 billion project to explore this metallic world. The
spacecraft, also named Psyche, is scheduled to launch on October 5,
2023. Unlike traditional landings, the spacecraft will orbit the
asteroid repeatedly, starting at a distance of 435 miles (700
kilometers) and gradually approaching it to end up just 46 miles (75
kilometers) from the surface.
After arriving in August 2029, the Psyche probe will spend 26 months
scrutinizing the asteroid’s geology, topography and gravity. Scientists
will look for signs of a magnetic field and compare the composition of
the asteroid to what is known about Earth’s core. The goal of the
mission is to gain valuable insights into the composition and structure
of planetary cores and shed light on the inner workings of our planet.
The Psyche mission represents an important milestone in our quest to
understand Earth’s inner workings. By studying a metallic asteroid like
Psyche, scientists hope to gain valuable information about our planet’s
core. This knowledge could have far-reaching implications for our
understanding of planet formation, as well as finding applications in
fields such as geology, seismology, and even space exploration.
– Exploring the mysteries of Earth’s core is a long-standing
challenge for scientists. The Psyche mission offers an innovative
approach that could lead to breakthrough discoveries.” – Dr. James
Smith, geophysicist at Stanford University
A former US Air Force fighter pilot asserts that he has deciphered
the method behind the extraordinary maneuvers of UFOs, reports dailystar.co.uk.
Over
the past two decades, numerous military encounters with these enigmatic
crafts have been reported, prompting a significant investigation by the
Pentagon.
One of the most renowned sightings occurred during the
USS Nimitz encounter, where fighter pilots witnessed a UFO descending
from 28,000 feet to just above sea level in less than a second.
This
astonishing movement would imply that the craft reached a staggering
speed of 19,000 miles per hour, a velocity that would be fatal to any
human pilot.
According
to Chris Lehto, a former USAF pilot, the craft exhibits two key
characteristics: it moves without inertia, essentially lacking weight,
and it accelerates at an incredibly rapid pace without affecting its
surroundings.

Chris
believes that the explanation lies within a technology that seems
straight out of science fiction. He proposes that the answer to the UFO
enigma lies in the Alcubierre Drive, a theoretical interstellar engine
conceptualized by Mexican physicist Miguel Alcubierre in 1994.
The
Alcubierre Drive employs a form of “space warp” technology, reminiscent
of what has been depicted in episodes of Star Trek. By bending space, a
craft inside a “warp bubble” could potentially travel at or even
surpass the speed of light without violating the known laws of physics.
While
the Alcubierre Drive remains a hypothetical concept with challenges to
overcome, Chris notes that the required energy is no longer believed to
be unattainably large.
Patents
filed with the US patent office outline the potential workings of the
drive, as well as another groundbreaking technology theorized by
American aerospace engineer Salvatore Pais.
Pais suggests that
high-powered rotating magnets could theoretically eliminate an object’s
inertia, and he has filed a patent for a starship based on this
principle.
However, Chris maintains skepticism regarding Pais’
theory. He explains that while Pais’s patent applications for the US
Navy attracted attention for their potential energy-related
applications, doubts have been raised about their feasibility. There is
speculation that they may be scams, pseudoscience, or disinformation
intended to mislead adversaries of the United States.
Alternatively,
rival theories propose that the “Tic Tac” UFO is a classified Pentagon
project testing similar advanced technologies discussed by Chris.
Scientists say they have found evidence of a new Earth-like
planet that has suddenly appeared in our Solar System and is orbiting
the Sun.
Physicists, including those from the National Astronomical Observatory
of Japan, said the planet is likely to be the mysterious ‘Planet Nine’
that was hypothesised to exist in the far outer edges of the Solar
System.
Several studies in the past have suggested there is likely an
undiscovered planet beyond the Kuiper Belt – a stellar disk of materials
such as asteroids, space rocks, comets around the Sun in the outer
Solar System past the orbit of Neptune.
Independent.co.uk reports: In the new research, published recently in The Astronomical Journal, scientists
found that some of the objects in the Kuiper Belt behave in a way
indicative of the presence of a small planet among them.
One such object, they said, is about 500 astronomical units (AU) from
the Sun, where 1 AU is the distance between the Sun and the Earth.
In comparison Neptune is at a distance of 30 AUs from the Sun.
Some of these were also found to have “odd” orbits suggesting they
are being pull by the gravity of a cosmic entity larger than those that
typically influence such objects.
Computer simulations run by the scientists indicate that the most
likely explanation for the observations was another hidden planet in the
Kuiper Belt.
“We predict the existence of an Earth-like planet,” researchers wrote in the study.
“It is plausible that a primordial planetary body could survive in
the distant Kuiper Belt as a Kuiper Belt planet (KBP), as many such
bodies existed in the early solar system,” they added.
If such a planet exists, researchers say it would have a mass about
1.5 to 3 times that of Earth with an inclination of about 30 degrees.
They say the theorised planet’s orbit would likely place it between 250 and 500 AU from the Sun.
Researchers say the discovery of such a planet close to the Kuiper
Belt can unravel new constraints on planet formation and evolution.
“In conclusion, the results of the KBP scenario support the existence
of a yet-undiscovered planet in the far outer solar system,” scientists
noted.
