Gold is rare on Earth in part because it's also rare in the universe. Unlike elements such as carbon or iron, it cannot be created within a star. Instead, it must be born in a more cataclysmic event —a short gamma-ray burst (GRB), like one that occurred last month.
Gold is rare throughout the Universe because it's a relatively hefty atom, consisting of 79 protons and 118 neutrons. That makes it hard to produce, even in the incredible heat and pressure of the 'chemical forges' of supernovae, the deaths of giant stars responsible for creating most chemical elements.
As it turns out, there's a giant asteroid that contains enough gold and other metals to make everyone on Earth a multibillionaire. And NASA uses gold to protect spacecraft from radiation. With all the gold out in space, extraterrestrial mining is a real possibility.
Well, at current market prices, 16 Psyche contain enough gold and other precious metals to be worth roughly $700 quintillion, which is enough to give every single human being on this planet a private fortune of nearly a hundred billion bucks.
In 2012, Yale University scientists published a study announcing the identification of a planet rich in diamonds. Called 55 Cancri e, the planet is "possibly covered in diamond, rather than water and granite," scientists explained at the time. The exoplanet is twice the size of Earth but has eight times its mass.
According to the US Geological Survey, the underground gold reserves are currently estimated at about 50,000 tons. From this perspective, a total of around 190,000 tonnes of gold has been mined like mentioned before, although these numbers vary.
There is an asteroid with a metal-composition that lurks around between Mars and Jupiter while orbiting the Sun and it is made up mainly of gold. Named 'Psyche 16', it was first discovered in 1852 by Italian astronomer Annibale de Gasparis and he named the asteroid after the Greek Goddess of Soul 'Psyche'.
Eventually, scientists calculated that the Sun contains almost 2.5 trillion tons of gold, enough to fill Earth's oceans and more. Still, that's just eight atoms of gold for every trillion atoms of hydrogen — a tiny amount when compared to the mass of the Sun.
But, in its elemental form, gold is significantly rarer than diamonds, Faul told Live Science. After all, carbon is one of the most abundant elements on Earth — especially in comparison to heavier metals like gold — and diamond is simply composed of carbon under immense pressure.
Gold. Interestingly, above-ground silver is actually more rare than gold. In fact, almost all the gold that has been mined to this day is still here, and its use is largely limited to currency, portable wealth, and jewelry.
Gold sank to the Earth's core during the planet's formation. It's only accessible today because of asteroid bombardment. Theoretically, it's possible to form gold by the nuclear processes of fusion, fission, and radioactive decay.
One study found there is only about one gram of gold for every 100 million metric tons of ocean water in the Atlantic and north Pacific. There is also (undissolved) gold in/on the seafloor. The ocean, however, is deep, meaning that gold deposits are a mile or two underwater.
As such, no series of chemical reactions can ever create gold. Chemical reactions change the number and shape of the electrons in an atom but leave the nucleus of the atom unchanged. The ancient alchemist dream of creating gold by simply reacting chemicals is therefore impossible.
The fact that the moon probe Surveyor V1 revealed the existence of an appreciable amount of carbon on the surface of the moon, in the neighbourhood of its site, lends strong support to a conjecture I made in 1965 (Optima 15, 160) that there may well be a relatively high concentration of micro-diamonds on the surface of ...
About 244,000 metric tons of gold has been discovered to date (187,000 metric tons historically produced plus current underground reserves of 57,000 metric tons). Most of that gold has come from just three countries: China, Australia, and South Africa. The United States ranked fourth in gold production in 2016.
Indian households have the largest private gold holdings in the world, standing at an estimated 24,000 metric tons. That figure surpasses the combined official gold reserves of the United States, Germany, Italy, France, China and Russia. See which countries have the largest gold reserves!
As gold prices go up, it's likely more people will be inclined to recycle old jewellery. Either to remodel into new pieces, or simply to cash-out. As gold prices go up, it'd be reasonable to expect that more gold is going to be recycled than at current rates (presently about 30% of supply).
Unlike other metals that form in the Earth's crust, gold comes from space. Stars are made mostly of helium and hydrogen, which provide light. Inside the star's core, nuclear fusion churns out energy. As the star's life comes to an end, a massive stellar explosion occurs known as a supernova.
noun, plural no·nil·lions, (as after a numeral) no·nil·lion. a cardinal number represented in the U.S. by 1 followed by 30 zeros, and in Great Britain by 1 followed by 54 zeros. amounting to one nonillion in number.
In 2019, NASA's Transiting Exoplanet Survey Satellite (TESS) discovered a super-Earth and two mini-Neptunes orbiting a faint, cool star about 73 light-years away in the southern constellation of Pictor.
The long chains then squeeze together to form crystalline patterns like diamonds. The dense diamond formations then drop through the layers of the mantle until it gets too hot, where they vaporize and float back up and repeat the cycle — hence the term "diamond rain."
