An unavailable form of helium that was formed shortly after the Big Bang erupted from the Earth’s metal base, a new modeling study has revealed.
Most of this gas in the world, called helium-3, is primordial and was formed after the Big Bang about 13.8 billion years ago. Some of this helium -3 combines with gases and dust in the solar nebula – the space, twist and fall that is thought to have led to the creation of the solar system.
The presence of the Earth in a large reservoir of helium-3 is further evidence to support the idea that the Earth was formed in a nebula of the developing sun, not on its side. the time of his disappearance, investigators say.
Helium-3 “is a marvel of nature, and a symbol for the history of the Earth, that there is so much of this isotope in the Earth,” said research lead author Peter Olson, a geophysicist at the University of New. Mexico, spoken in a language (opens on new page).
Helium-3 is an isotope, or similar, of helium that has one neutron instead of two normal elements in its nucleus. It is a rare gas, containing only 0.0001% of the helium on Earth. From various processes, such as the radioactive decay of tritium, a radioactive isotope of hydrogen. But because helium is one of the oldest in the universe, most of the helium-3 comes from the Big Bang.
Scientists have already found that about 4.4 pounds (2 kilograms) of helium-3 escapes from Earth each year, mostly in the middle of the ocean. tectonic plates (opens on new page) group, the researchers wrote in the study, which was published online March 28 in the journal Geochemistry, Geophysics, Geosystems (opens on new page).
“This is enough to fill a balloon the size of your desk,” Olson said.
But scientists do not know how much helium-3 is found in the base and clothing, or how much helium-3 is in Earth’s deposits.
For the research, the research team compared the amount of helium to two important periods in Earth’s history: when the earth was first formed, when helium accumulated, and in after the foundation of the world. month, as more of this gas is lost to our planet. Scientists believe that the moon was formed when an object as large as Mars and Earth met about 4 billion years ago.
This event melted the Earth’s waste so that most of the helium in our planet could escape.
However, the Earth did not lose its helium-3 at that time. It holds some of the rarest gases, constantly flowing out of the earth. The reason for such water is a good one, “because it doesn’t have to deal with significant effects compared to other parts of the earth’s system,” the researchers wrote in the study. It does not enter the tectonic plate carrier, that is. release helium gas.
The researchers compared the new helium-3 leakage count with features of helium isotope activity. These figures put between 22 billion pounds (10 teragrams) and 2 trillion pounds (1 pentagram) of helium -3 on Earth – a large amount, indicating that the Earth in a solar nebula with high levels of gas.
Their features of gas conversion “change during the formation of the Earth and development in relation to the metal base as a source of leaky water to provide the rest of the Earth with helium-3, “the researchers wrote in the study.
However, because these results are related to comparisons, the results are not robotic. The team needs to make a lot of assumptions – for example the Earth took in helium -3 as it did in the solar nebula, helium entered the base metals and some helium left in the reason for the dress. These assumptions, along with other doubts, relate to the length of the solar nebula in relation to the speed of the Earth’s movement, which means that there is less helium-3 in it. the reason is before they can count, scientists say.
But researchers hope to find new evidence to support their findings. For example, the presence of other gases produced by the nebula, such as hydrogen, flowing from Earth from the same locations and values as helium-3, could be a “gunshot” that indicates the cause is the cause, Olson said. “There are more mysteries than facts.”
