ince many centures of human history gold has been fascinating us.When we think about gold, we think about wealth and currency. Gold has a long history of symbolizing financial power in european cultures.However, pre-Columbian people had a different viewpoint on this matter.In many pre-Columbian civilisations gold was seen as divine and was believed to had fallen from the sky.
Tha amount of gold that a person possessed represented rather amount of spirituality than wealth and social status.
Modern science permits us to answer on the question where is gold from and solve the mystery.
All gold in the Universe may come out of collision of neutron stars – this is the last theory resulting the observation of neutron stars colliding. This collision can be observed once in about 100 000 years. Unlike elements like carbon or iron, gold cannot be created within a star. Instead, it must be born in a more cataclysmic event – like one that occurred last month known as a short gamma-ray burst (GRB). Observations of this GRB provide evidence that it resulted from the collision of two neutron stars – the dead cores of stars that previously exploded as supernovae. Moreover, a unique glow that persisted for days at the GRB location potentially signifies the creation of substantial amounts of heavy elements – including gold.
“We estimate that the amount of gold produced and ejected during the merger of the two neutron stars may be as large as 10 moon masses – quite a lot of bling!" says lead author Edo Berger of the Harvard-Smithsonian Center for Astrophysics (CfA). A gamma-ray burst is a flash of high-energy light (gamma rays) from an extremely energetic explosion. Most are found in the distant universe. Berger and his colleagues studied GRB 130603B which, at a distance of 3.9 billion light-years from Earth, is one of the nearest bursts seen to date. The resulting collision brings together so much mass in one location that it collapses on itself, triggering the formation of a black hole. Close observation of this latest neutron star collision has revealed the contents of this ejected matter.
Because scientists know how often these collisions occur, and can now infer roughly how much material is generated with each event, they can compare the total amount of heavy elements produced by neutron star collisions with the known amount in the universe. The team’s conclusion, which was also published in The Astrophysical Journal Letters, is that these events are a sufficient explanation for all of our heavy elements, including gold. After it’s created in these sorts of collisions and ejected outward, the heavy elements are eventually incorporated into the formation of future stars and planets in the surrounding universe. Which means that all the gold on Earth probably comes from the collision of two distant stars.
So the pre-Columbian people belief that gold had fallen from the sky come true…..
