A new study proposes that our Universe may have appeared thanks to a low mass supernova as the scientists propose a new beginning for our Solar system.
The latest study was carried out by a team of University of Minnesota’s School of Physics and Astronomy researchers led by professor Yong-Zhong Qian.
The results of the study were published in the Nature Communications journal.
Also joining in on the research are Projiwal Banerjee, the study’s lead author, the University of California, Berkley’s Wick Haxton, and Monash University’s Alexander Heger.
The birth of our Solar Systems is one of the most asked, discussed, and controversial scientific questions.
As the generally accepted idea is that the Universe was formed by the so-called Big Bang, a new team of scientists has come to propose a change in triggers.
Professor Qian and his team have proposed a new Solar system mother in the form of a low mass supernova. A low mass supernova is the name given to star which has reached the ending of its life-cycle and is exploding.
The team of researchers focused and based their research on short-lived nuclei. These radionuclides are the result of a stellar explosion which has left traces.
As these short-lived nuclei were known to have existed at the beginnings of our solar system, traces of them were found on meteorites.
The radionuclides are present in meteorites in the form of isotopic anomalies.
One of the causes which have been pointing towards a supernova beginning are these exact meteorite isotopic anomaly traces.
Studies seem to suggest that the reason for the nuclei short lifespan is their origins. Further research also seemed to note the fact that a high-mass supernova would not have left such traces.
Beryllium-10, a 10 mass units, 4 protons, 6 neutrons nuclei marked the beginning of their research. Initial studies and models revealed that Beryllium could be determined by both low and high mass supernovas.
The researchers used models of known low mass supernovas so as to test their theory. By using these models they have also proven that the aforementioned celestial formations are the source of the nuclei.
As such, low mass supernovas were determined as being the most likely source for the appearance of these early, short-lived nuclei.
With these short-lived nuclei being amongst the first traces to appear and still be available in relation to the Universe, scientists are proposing a new study.
The team is planning on furthering and advancing their research as they believe that they may have stumbled upon one of the Universe’s great mysteries.
To put it simply, scientists believe that some 4.6 billion years ago, a cosmic event disturbed a cloud of dust and gas.
This, in turn, is thought to have triggered a gravitational collapse which most probably led to the appearance of our solar system.
Previous studies believed a high mass supernova as being the most likely cause. However, the new study to be carried out by the scientists will seek to determine and prove that the trigger that pulled the gun on our Universe was a low mass supernova.
