Because the Earth’s core can cool: Cold can make our Earth uninhabitable. How can the earth become like mars.
London – in a world astronomy Dazzle and anxiety lie close to each other. Latest example: A few days ago it was still said that a file The asteroid can save the global economy on its own. Now all orgasm is suddenly null and void?! According to British Express, thermal processes could make human life on Earth impossible. A research team reported cold Earth and made comparisons to the icy desert of Mars. Will the Earth soon turn into a cold, deadly wasteland? What is behind the search?

Cooling the Earth’s core: the research team warns that the Earth can emit a lot of heat
Why is science actually interested in exploring a second Earth? as the last one Göttingen’s research team discovered the second Earth*, it was definitely mainly about taking astronomy to a new level, which is outer space And better understand all its phenomena. In terms of climate change and resource depletion, dealing with one plays a role Second, Earth is probably ‘better’ as a place to reboot However, a more important role.
The search for other planets that could provide an important potential habitat also appears to be in light of the latest research: Earth could cool, according to the researchers. In order to understand the processes behind it, you have to go back to the beginning. Our Earth was formed about 4.5 billion years ago. Since time immemorial, the Earth’s core has been continuously releasing heat through the mineral bridgemanite. The core has long melted and meets the most common minerals in the mantle at the mantle boundary. So heat energies are transferred and transmitted more and more towards the Earth’s surface.
What are the layers of the earth called?
Earth’s inner core
Heat flows from the inside out—a process that, Express reports, eventually means Earth’s core may cool completely one day. There is talk that Earth could take on an evolution similar to Mars. He, too, was vibrant. Now, however, the Red Planet is known only as the Barren Earth. However, the orb depicts an interesting phenomenon. According to the previous The head of NASA could soon make colonization of Mars “possible” through complex processes. Anyway, it’s clear why NASA would like to continue researching the issue of life on Mars in the next 10 years want to answer.
Earth Composition: Cooling magma produced the Earth’s crust
The past few years of research have made Earth’s composition more and more understandable. According to an article by weltderphysik.de, the early days of our planet were marked by the fact that the Earth was enveloped in an ocean of magma. In astronomy, one talks about the ocean of magma, which is also responsible for the formation of the moon was necessary. But the Earth’s crust can develop only thanks to the magma ocean. News.de reports that one day the magma cooled, after which the earth’s crust emerged from the mineral bergamanite.
The research team, which addressed the potential problem of a cooling planet, began irradiating the metal with a laser. Japanese scientist Motohiko Murakami and his colleagues wanted to explore the relationship between temperature and pressure between Earth’s layers. In the course of their experiment, they increased the atmospheric pressure between Earth’s layers of the mantle and core. The temperature of the bridgemanite mineral rose – and the researchers around Murakami came to a conclusion.
When did the earth get cold? According to researchers, much faster than expected
When bridgmanite cools, post-perowski mineral is formed – a finding that was already known to science in advance, but may still be relevant for later research. As Murakami says, “However, as the amount of post-perovskite increases at the core-mantle boundary, the cooling of the mantle may accelerate further.” The research team expects the experiment to provide “a new perspective on the evolution of Earth’s dynamics.” In any case, the results so far speak for themselves.
According to Murakami, all the results indicate that “Earth, like the other rocky planets Mercury and Mars, is cooling and becoming inactive much faster than expected.” In research circles, one does not want to give up the Earth completely. Why is the comparison with Mars nonsense?
Earth’s core is cooling – like Mars once did? In comparison, the red planet is much smaller
The Red Planet is smaller than the Earth and therefore could cool down faster. There is currently no reason to panic about a cold shock in the near future anyway: “We still don’t know enough about this type of event to determine its timing,” Motohiko Murakami confirmed. Thus, there are no predictions about whether it will be cold and when the Earth can cool down – contrary to the calculations, When the sun can destroy the earth.
