Have you ever wondered how exactly the precious metals came to be? Why are they so rare in the composition of the Earth? Although there are plenty of convincing answers to these questions provided by theology, scientists have been doggedly pursuing the answer since at least the middle of the 20th century.
In the six-plus decades since, they have still yet to turn up any definitive or particularly compelling answers. Yet, the new discovery of a galaxy 98,000 light years away could hold the key to unlocking this puzzle.
The Lustrous Reticulum II
The galaxy in question was discovered last year orbiting our Milky Way Galaxy and is known as Reticulum II (Galaxies and constellations are generally named for their shape). Interestingly, Reticiulum II is absolutely loaded with precious metals–gold, silver, and platinum.
What’s strange is that the researchers studying Reticulum II concluded that this abundance of precious metals could not have originated there. So-called “r-elements” like the precious metals are very heavy, and require a great deal of energy to form. In fact, this process is so energy-intensive that scientists haven’t been able to replicate it in a laboratory.
Anna Frebel, a researcher and astrophysicist from Massachusetts Institute of Technology (MIT) involved in the study, confirmed this: “The process for making [these elements] just doesn’t work on Earth. So we have had to use the stars and the objects in the cosmos as our lab.”
Just a Theory
The theory about how the precious metals came to be is as follows:
“R-process elements were created by neutron star explosions in dwarf galaxies and were transported to our planet by getting embedded into stars and asteroids.”
Part of why Reticulum II may help solve this mystery is that neutron star collisions are far more common in the early formation of dwarf galaxies than they were in the early history of the Universe.
This research has led to an intriguing implication–that the precious metals originally came to our planet from elsewhere in outer space. If this is the case, Reticulum II could offer a wealth of insight into how these metals are made and where else we might find them.
