The life span of humans is only a few decades, and long-lived people can get a hundred years old. Therefore, compared with the mountains, rivers and rivers in nature, many people lament the ephemeral of life and the longevity of heaven and earth. However, in fact, nothing in this world is immortal. Even the sun, moon, stars, there will be a day of death.
From this perspective, it is not only the existence of the earth, but also in the universe.
1. Phobos, which will eventually die,
, just like the earth, , Mars, is also a planet with satellites. Moreover, there are two planets on Mars: Phobos and Phobos. Among them, many scientists believe that based on the force of Mars, about 40 million years later, Phobos will disappear from above Mars: either the Phobos hit Mars and become a mountain on Mars (of course, it is also possible to say it is a mound), or it will be directly to pieces and eventually become the halo of Mars.
In fact, like Mars, when other planets are torn into pieces and then turned into halos, it is nothing new in the solar system: about 100 million years ago, there was a planet around Saturn , which was torn into pieces by Saturn's gravity, and finally formed Saturn's rings . Of course, Saturn's rings will disappear one day in the future. Even the Earth has had collisions with other planets in history and once had the Earth ring.
Rings of Mars, Saturn, and Earth rings have actually witnessed one thing: that is, the planet will no longer exist. There is even a theory: assuming that our earth is too close to Jupiter , then the earth may also be torn into pieces by Jupiter's force and eventually become Jupiter's halo. Of course this is not alarmist, but the real astrophysics .
Assuming that one day the earth will appear near Jupiter for no reason, then for humans on Earth, everything their homeland and possess will be torn to pieces and distributed over Jupiter.
2. The demise of the earth
Of course, it is unlikely that the earth is close to Jupiter. However, this does not mean that the earth is not likely to be destroyed. Scientists believe that in about 7 billion years, the sun will evolve into an red giant , and the planets in the solar system will be heavily affected at this stage. The final outcome is that the sun that becomes a red giant will annex the major planets of the solar system, including the earth, and the earth will no longer exist.
Of course, 7 billion years are essentially not much different from ten thousand years for humans, and they are all unattainable years. But one thing is undeniable, that is, the earth will also die one day. As the sun becomes red dwarf , it also means that the sun is also beginning to demise.
3, the Betelgeuse that is about to explode,
Betelgeuse is about 640 light years away from the earth. In other words, the Betelgeuse we are seeing now is actually the image 640 years ago - that is, the state of the early Ming Dynasty in China. For the earth, Betelgeuse is a very long distance away. However, Betelgeuse's fate has attracted great attention from human astronomers and cosmologists. Because, since 1996, the brightness of Betelgeuse fluctuated. Sometimes, Betelgeuse makes people feel bright, and sometimes, Betelgeuse makes people feel dark.
Betelgeuse is an red superstar , so in this state, it makes people wonder if Betelgeuse is going to face the crisis of explosion. After some speculation and prediction, scholars of astrophysics finally concluded that Betelgeuse will explode in about 900,000 years. Perhaps, the explosion of Betelgeuse will no longer exist.
Although the earth is 640 light-years away from Betelgeuse, if Betelgeuse explodes, it will inevitably produce gamma rays . Many scholars believe that the Betelgeuse explosion will not affect the earth, but in fact, whether it really affects it or not, for the earth, it will happen 900,000 years later.
In fact, looking at the entire universe, too many planets are heading for destruction. So, nothing in this world is immortal. For humans, living every day is the most important thing.
