A groundbreaking study from the University of Copenhagen has presented a fresh perspective on Earth’s formation, suggesting it occurred in a few million years, far quicker than the previously believed 100 million years. The research indicates that Earth was formed through the fast accumulation of small pebbles, and water’s existence is a byproduct of this formation process. This theory provides a promising outlook for the potential of habitable planets beyond our Solar System, given that water is a critical ingredient for life.
Earth formed in a few million years, much quicker than previously thought, through the rapid absorption of pebbles, dust, and icy particles, according to a new study from the University of Copenhagen. This finding enhances the likelihood of other habitable planets in the Universe due to the byproduct of water from this formation process.
When we walk around in our everyday life, we might not think of the Earth itself very often. This planet is, however, the foundation of our existence, providing the air we breathe, the water we drink, and the gravity that holds us to the ground.
Until recently, researchers believed that it took over 100 million years for Earth to form, with water being delivered by fortuitous collisions with water-rich asteroids such as comets. A new study from the University of Copenhagen, however, suggests that Earth’s formation might not have been a matter of pure luck.
A New Theory of Earth’s Formation
Professor Martin Bizzarro of the Globe Institute and co-author of the study explains, “We show that the Earth formed by the very fast accumulation of small millimeter-sized pebbles. In this mechanism, the Earth was formed in just a few million years. It appears that the presence of water on Earth is a byproduct of its formation.”
The research results indicate that Earth was created much faster than previously thought, and the presence of water is an anticipated outcome of this formation process. This information has significant implications for our understanding of planets outside our Solar System.
Implications for Habitability in the Galaxy
“With this new planet formation mechanism, the chance of having habitable planets in the galaxy is much higher than we previously thought,” Bizzarro says. Habitability is the potential for a planet to have the right ingredients at its surface for life to develop, and water is a key ingredient. Associate Professor Martin Schiller, also a part of the study, elaborates, “People have debated how planets form for a long time. One theory is that planets are formed by the gradual collision of bodies, progressively increasing their size over 100 million years. In this scenario, the presence of water on Earth would need a sort of chance event.”
Silicon Isotope Constraints on Terrestrial Planet Accretion
Monte Carlo simulations of Fe–Ni isotope evolution of the terrestrial mantle during concurrent accretion and core formation in μ54Fe57/56–μ58Ni62/61 space. Ellipses represent 2 s.e. intervals for the measured BSE, IIIAB and CI isotope compositions. The grey lines represent the evolution of the proto-Earth mantle during pebble accretion. The colored lines represent various outcomes of the Moon-forming giant impact depending on the fraction of the Theia’s core that equilibrated with Earth’s mantle during impact. The equilibration degree is shown by the color scale and circles highlight 10% and 30% of equilibration with Theia’s core. Credit Nature, DOI: 10.1038/s41586-023-06135-z
Role of Dust Particles in Earth’s Formation
A paradigm shift in this belief, however, is introduced by the new study, which offers a fresh theory of Earth’s creation. “There was a disk around the young Sun where the planets were growing. The disk was filled with small dust particles. Once a planet reaches a certain size, it sort of acts like a vacuum cleaner, sucking up all that dust very quickly, which contributes to its growth to Earth size in just a few million years,” explains Ph.D. student Isaac Onyett, the corresponding author of the study.
This “vacuuming” of small dust particles played a pivotal role in Earth’s formation and ensured that water was delivered to our planet. The disk also contained icy particles, which were absorbed along with the dust, contributing to the presence of water during Earth’s formation. This shift in understanding raises the probability of water being present on other planets.
Predicting Water on Other Planets
“This theory would predict that whenever you form a planet like Earth, you will have water on it. If you go to another planetary system where there is a planet orbiting a star the size of the Sun, then the planet should have water if it is in the right distance,” asserts Bizzarro.
The researchers used silicon isotopes to understand the mechanisms and timescales of planet formation. By analyzing the isotopic composition of over 60 different meteorites and planetary bodies, the team established genetic relationships between rocky planets like Earth and Mars and other celestial objects. This approach offered insight into the types of building blocks that assembled to form Earth and the process by which they came together.

The Bible says, God.
Scientists say, stuff happens.................
Louis Farrakhan’s house...................
I believe six days, too.
Same folks who do the climate stats??
God Himself.
” A new study from the University of Copenhagen,”
I watched a documentary weeks ago on this. Not new.
Everyone thinks they know how God did it but they don’t know crap
If I knew how God did anything, I’d be rich.............I’m not....................
as if designed that way... hmmmmmm
So...
Basically it is really all about climate change?
From cold, watery, pristine dust particles to a hot ball surrounded by a watery surface...
Glad that is cleared up...
“Professor Martin Bizzarro ...”
It seems that this is Bizzarro world.
Man can not create. He can only MANipulate.
Science continues to make up new theories that continuously contradict their old theories.
I do like this latest bit of nonsense. As they try and throw in the Alien Life baloney.
‘The Bible says, God.’
and exactly how did God happen...?
Let’s write another paper with no way to prove or disapprove the theory.
God is eternal. He has no beginning, He has no end. Organic life is a genetic mutation. Our lives are measured in years and decades. We wither and die. Before Him we are nothing. We exist because He allows it; we will be destroyed because He demands it.
God plans well.
Thanks Red Badger. A nice two-fer.
