When will the world end? Discovered by the world of CONICET – Diario El Ciudadano y la Región

Christian Giubon is a researcher and associate professor at the Institute of Theoretical and Experimental Astronomy (Iate) and the Scientific and Technological Center (Conicet) and with a team of experts he was able to determine when and how the end of the world will happen. . To reach this conclusion, he studied the evolution of stars and their relationship to the planets that surround them.

“The work consists of studying how the size of stars develops according to their lives, and what happened with the giant planets around other stars that are similar to the Sun. Each of these that we see in the sky has one or more nearby planets, then by observing stars from different ages, a reconstruction is made history and one can infer how the process is going and what will happen to the planets around it,” Gibbon explained.

The researchers had to understand the evolution of stars and what equations govern their size and temperature. “This has been applied to the Sun and the number of years of fuel remaining has been determined to increase its size and reach the orbit where the Earth is. This will happen in about 5,000,000,000 years, much longer than we will live.”

This conclusion was reached through physics: “Everything we know about nuclear energy and its reactions and the amount of energy released we learned from astronomy. The sun conducts nuclear reactions inside it and this is what makes it contain light, energy and heat. Nuclear energy is balanced with gravitational energy, and this is the reason Being that big. When it runs out of fuel now, which is mostly hydrogen, it will start using helium and get bigger. This will change the conditions of physics. That’s what we’ve tried to model and predict in terms of time.”

“Imagine that the planet is a ball of gas with a high temperature. As it increases in size, the sun will swallow Mercury and Venus, which are closer, and when it begins to multiply, the atmosphere is closer and closer to Earth. After that, it will expel all of the Earth’s atmosphere, leaving a planet without an atmosphere Atmospheric and certainly without gases. And at some point, it will end up swallowing the Earth, ”he explained, detailing what the end of the world will be like.

He explained: “By then there will be no living being, we shouldn’t even worry. Today we’re talking about inhabited space travel, imagine what we can do as humanity in 100 or 200 years, we can search for other planets, colonize different parts of the universe, Now that we know that in every star there is at least one or several planets.”

Are there other dangers to humanity?

“The most dangerous thing for mankind has always been the asteroids orbiting the solar system, if there are any large asteroids that can hit the Earth. There are many programs from NASA and other agencies that monitor, but there is a high degree of uncertainty, and the space is very vast, and it is huge.” , and so full of emptiness and at the same time stuff, that one doesn’t have all the cards in hand to know what’s going to happen. It’s not like it’s going to happen tomorrow, but you never know, you’re never quite sure,” declared the expert.
