All the metals in the world are white metal: new study
A new study has found that all the metals on earth are white.
The research, which is published in the journal Physical Review Letters, shows that the ratio of iron to copper in the Earth’s crust, the key determinant of its magnetic properties, is the same across all of its metallic elements.
“This is a remarkable result, given that we know so little about the physical processes that control the physical properties of the Earth,” lead author Peter Rietveld from the University of Copenhagen, Denmark, said in a statement.
“The results indicate that we cannot explain the distribution of these metals using conventional methods.”
Copper, for example, has a much lower concentration of copper than other metals, and has a lower melting point, meaning that the metallic components in its structure are more readily transformed into their component metals when heated.
Iron, on the other hand, has much higher melting point than copper, meaning it is more easily converted to its component metals.
The results are important because the discovery of the magnetic properties of some metals could potentially lead to more accurate predictions of Earth’s magnetic field.
The discovery of this magnetic property was made using the neutron star merger, an event where an extremely large number of neutron stars collide with one another, generating powerful explosions.
The collision of the neutron stars causes them to lose energy, which creates the intense gamma rays that can disrupt Earth’s magnetosphere, which protects us from solar radiation.
This discovery of how Earth’s environment changes over time could help scientists to predict when the magnetic field is likely to start to fluctuate, a process known as magnetic reconnection.
While the study does not prove that white metals exist, the results are intriguing, and could help us to understand how the Earth is constantly being reshaped by these collisions.
“Our study shows that white metal is not the only metal with a magnetic property that is not easily understood,” said lead author Stefanie Rehm from the Department of Physics at the University Leuven, Belgium.
“What we found is that white is not just another metal.
There is another metal out there with a different magnetic property.”
The researchers have previously found that white-metal materials, which are more common than black, were also less likely to undergo magnetotailing, a phenomenon where the Earth starts to rotate faster than the Sun and becomes hotter.
