fate the solar system – Although we often feel that the earth beneath our feet is firm and comforting, nothing in the universe is supposed to last forever. One day our sun will die, and before its nucleus is compressed to the size of a white dwarf, it will release much of its mass into space. Then the remnant of the sun will gradually lose its heat after a thousand trillion years until nothing more than a cold, dark, dead rock mass remains. Of course, at that time there will be no more news about the solar system. According to the new simulation, it will only take 100 billion years for the planets in the solar system to escape through the galaxy as the dead sun passes, leaving no trace of the system. Astronomers and physicists have spent at least hundreds of years trying to figure out the ultimate fate of the solar system. “Understanding the long-term dynamic stability of the solar system is one of the oldest puzzles in astrophysics, and its history goes back to Newton himself because Newton speculated that bilateral interactions between planets would eventually destabilize their orbital dynamics.”

But the issue is more complicated than you think. The greater the number of objects in a dynamic system that interacts with each other, the more complex that dynamic system becomes and the more difficult it is to predict the position of objects in it. This challenge is called the “polymorphic problem.” If this period is more than 5 to 10 million years, a great deal of uncertainty will appear in the calculations. But if we can figure out the fate of the solar system, then perhaps we can know how the universe evolved on a scale far beyond its current age of 13.8 billion years. In 1999, astronomers predicted that the solar system would slowly and steadily It will disintegrate over a period of at least one billion billion years (1,018 years or a quintillion years). They calculated how long it would take for Jupiter and Saturn to orbit Uranus. Therefore, according to the results of this group, the solar system will disintegrate sooner than we thought. The primacy of the sun will be affected. About 5 billion years later, the sun swells at its death and turns into a red giant, then swallows Mercury, Venus, and Earth. The sun then releases about half of its mass into space in the form of solar wind. The mass of white dwarfs left by the sun is only 54% of the current mass of the sun. Second, when the solar system orbits the center of the galaxy, almost every 23 million years, other stars approach the solar system so close that they can disrupt the orbits of the planets.

“Considering the reduction in the mass of the sun and the swelling of the orbits of the outer planets, the impact of these uninvited guests will increase,” the researchers wrote in their paper. “If enough time is available, some of these stars could get so close to the solar system that they can grab the remaining planets or destabilize their orbits.” The powerful Hoffman 2 Cluster was implemented for outer planets (Mars was not included in the calculation to reduce costs because its effect was negligible). These simulations were performed in two stages: one stage until the end of the solar mass reduction and the other stage in the period after that.

Red Giant

Although performing 10 simulations may not provide a good statistical population, the researchers found that the same scenario occurs in each simulation. As the sun eventually evolves into a white dwarf, the orbits of the outer planets become larger, but the planets remain stable in their orbits. Nevertheless, Jupiter and Saturn are locked in a steady 5-to-2 orbital intensification – every five times Jupiter orbits the Sun, Saturn orbits the Sun only twice (this inevitable orbital intensification has been raised many times, especially by Isaac Newton himself). Inflation of planetary orbits, together with the effects of planetary orbital intensifications, make the system more vulnerable to disturbances due to the close passage of stars. Thirty billion years later, such perturbations disrupt stable orbits, causing the planet to easily escape the gravitational pull of its host star. All the planets in our solar system, with the exception of one planet, go out of orbit and roam freely in the galaxy like the “Rouge Planets”.

The last remaining planet will orbit the sun in another 50 billion years, but its fate is certain. Eventually, the planet will be ejected from its orbit under the influence of gravity. Eventually, 100 billion years after the sun turned into a white dwarf, nothing will remain of the solar system. The time scale of this scenario is much shorter than the scale proposed in 1999 for the final fate of the solar system. And researchers have been careful to point out that current observations of the galaxy’s local environment and estimates of passing stars are both likely to change in the future. So this scenario is by no means final and may change in the future. Even if the estimates for the destruction of the solar system change again, the same thing will happen billions of years from now. Humans are unlikely to survive billions of years to witness such an event. So do not worry and sleep well! Further details of the study are published in The Astronomical Journal.

Although we live on Earth and want to travel to other planets like Mars, nothing on the planet lasts forever, and one day they will all be destroyed. This day will probably be earlier than our previous predictions. One day in the future, our sun will die, and before its nucleus turns into a white “white dwarf”, it will lose a lot of mass and emit heat so that In the end, nothing was left but a cold, dark and dead rock. This process will take place in another trillion years. By then, other solar systems will be destroyed. According to new simulations, it will take only 100 billion years for each planet in the galaxy to escape, leaving the dying sun alone. Astronomers and physicists are trying to find out the final fate of the solar system.
