(ORDO NEWS) — Scientists have been studying the path of our planet and the entire solar system through the Galaxy and have stumbled upon a strange cycle that repeats approximately every 200,000 million years .
In addition to rotating on its axis, our planet rotates around the Sun and passes through the Milky Way galaxy, which itself is in motion. We travel through the Milky Way galaxy as a giant space family.
In addition to being huge and massive, our Milky Way galaxy is also in motion. It has stars, planets, gas clouds, dust particles, black holes, dark matter, and more, all of which contribute to and affect its gravity.
From our point of view, the Sun rotates once every 220-250 million years, being at a distance of about 25,000 light-years from the center of our galaxy.
Everything is in motion
The Milky Way galaxy, known as the spiral galaxy, is made up of four main spiral arms and many arm fragments known as offshoots.
Everything in our galaxy, including our solar system, travels through space through these spiral arms.
How does this affect our planet, if at all?
To find out, geologists decided not to look into space, but deep into the Earth, observing tiny grains of sand, in the hope of understanding how our planet was built and what processes could contribute to its formation.
Let’s ask a geologist
Geologists observe the composition of mineral grains smaller than a human hair. They then extrapolate the supposed chemical processes to understand how the Earth formed.
Scientists are now linking the tiny grains to Earth’s place in the galaxy, taking this observation to new heights. Their findings are reported in a scientific paper published in the journal Geology titled ” Did Transit Through Galactic Spiral Arms Lead to Crust Formation on the Early Earth? “.
The goal of astrophysicists is to better understand the universe and our place in it. Physicists develop models to describe the orbits of astronomical objects using the laws of physics.
Despite what we may believe, the surface of the planet has undoubtedly been affected by the cosmic environment. Meteor impacts, periodic changes in the Earth’s orbit, fluctuations in solar radiation and gamma-ray bursts are all part of this process.
Recently meteorite impacts have been linked to the formation of the Earth’s continental crust, forming floating “seeds” in our planet’s outer layer.
Now the researchers have identified a cyclicity in the production of this early continental crust , which indicates the presence of a powerful driving force.
Magma, molten or semi-molten material, is responsible for the formation of many rocks on Earth. In addition to the fact that magma forms from the mantle the hard, slowly flowing layer beneath our planet’s crust older pieces of pre-existing crust can also be reheated to form magma. Solid rock is formed when liquid magma cools.
Mineral grains grow as magma cools and can trap decaying elements such as uranium, creating a kind of stopwatch that records the age of minerals.
In addition to trapping other elements, crystals can also capture the composition of the parent magma.
This information, combined with the composition of the earth’s crust, allows scientists to reconstruct the chronology of its formation.
Using the Fourier transform, they can decipher the fundamental frequencies of the signal.
Based on this approach, the production of the crust on the early Earth had an approximate cycle of 200 million years .
An even weirder cycle
A similar cycle can be found elsewhere. The Milky Way galaxy and our solar system revolve around the supermassive black hole at its center, but at different speeds.
As our solar system races around the arms of the galaxy, the spiral arms rotate at 210 kilometers per second, while the sun moves at 240, meaning our solar system moves along the spiral arms.
Based on this model, our solar system enters the spiral arm of the galaxy approximately every 200 million years .
There may be a relationship between the time it takes for a galaxy to rotate through the spiral arms and the time it takes Earth’s crust to form but why?
The Oort Cloud is believed to revolve around our Sun at the far reaches of the Solar System.
It is hypothesized that when the solar system periodically moves in spiral arms, the interaction between it and the Oort cloud can expel material from the cloud, bringing it closer to the inner solar system. There is even a possibility that some of this material will hit the Earth.
Scientists believe that these periodic high-energy impacts can be tracked by tiny mineral grains that have kept a record of the formation of the earth’s crust. Collisions with comets excavate large volumes of the earth’s surface, which leads to the melting of the mantle as a result of decompression.
