Other planets in the universe explode, will the earth be affected?

Our earth has never been really safe. There is a lot of powerful energy in the whole universe, which is enough to destroy the earth easily. For example, 65 million years ago, an asteroid with a diameter of 10 km hit the earth, which led to the tragic fifth extinction event on the earth, and the dinosaurs that ruled the earth for 65438+600 million years. All of them were killed in this incident. Of course, there is also an extremely deadly explosion in the universe, that is, supernova explosion. Supernova explosions are caused by some stars. Running to a certain age, the surface exploded violently. This kind of explosion is extremely bright, and the sudden electromagnetic radiation in the process can often illuminate the whole galaxy where it is located.

Simply put, when some stars in the universe come to the end of their lives, violent explosions may occur. Because the mass and volume of stars are very large. Therefore, their shock waves may span hundreds of light years and bombard our earth, which will eventually lead to a devastating blow to life on our earth.

And this is really not alarmist. 640 kilometers away from the earth, there is an extremely dangerous time bomb, which is Betelgeuse. Betelgeuse is the fourth order of Betelgeuse, also known as Alpha Orion. It is a red Supergiant star in Orion. It is the twelfth brightest star in the earth's sky except the sun. Betelgeuse is currently in the red giant stage.

So its volume has expanded to an unimaginable size. If Betelgeuse is affected to the center of the solar system, its surface will surpass the asteroid belt. And may reach and surpass the current orbit, thus completely sweeping Mercury, Venus, Earth and Mars. Because Betelgeuse is too far away from us. In addition, the volume of Betelgeuse has been changing, which makes it almost impossible for scientists on earth to accurately measure the specific size and mass of Betelgeuse. What is certain, however, is that Betelgeuse will probably explode soon. It is even possible that Betelgeuse has exploded.

Scientists have been interested in Betelgeuse since it was first discovered by humans in 1920. In 20 19, scientists found that the brightness of Betelgeuse began to change. Most people think Betelgeuse will explode soon. Until 2020, with the intensification of the brightness change of Betelgeuse, some scientists think that this plot may have arrived here. However, in subsequent observations, scientists found that the brightness of Betelgeuse was slowly rising, which meant that Betelgeuse did not explode. Scientists estimate that the four dates of Betelgeuse exploded within 654.38+0 million years. So what will happen to us once Betelgeuse explodes? According to the current scientific cognition. The explosion of a distant super nova is unlikely to bring any devastating results to the earth. Because the particles released by supernova explosion are very small, neutrinos are harmless to human body. When a star explodes, we will first observe a cloud of particles called neutrinos, which will pass through the earth, even if a supernova explosion will illuminate our galaxy. In theory, 99% of the energy will be released into these particles. But when these tiny particles pass through the earth and our bodies, they won't do us any harm. At the same time, because Betelgeuse is more than 640 light years away from us, according to the current scientific cognition, supernova explosion will only affect the life on the nearby planets within ten light years.

Therefore, our earth is far from the influence of Betelgeuse. Of course, some people are worried about the gamma ray explosion after Betelgeuse's explosion, if the direction is just aimed at the earth. It may also destroy the earth's biosphere. But don't worry about this, because Betelgeuse is a red Supergiant star with a thick hydrogen coating, which represents. Once Betelgeuse explodes, the jet generated by its explosion will be swallowed up by the hydrogen cladding. Meanwhile, Betelgeuse is a red Supergiant star, while the red Supergiant star breaks through radiation. It is impossible to hand in gamma rays, only ultraviolet rays and visible light, which cannot harm the earth's atmosphere. So even if Betelgeuse does explode, Our earth is not in danger. At present, scientists believe that Betelgeuse is likely to have these two endings. First, it will become a neutron star with high density after the big bang. Another kind. It is believed that he will become a black hole with eight times the mass of the sun after the Big Bang. Once Betelgeuse explodes, we will reach the earth in about 640 years. Seeing an extremely bright celestial body, its brightness is likely to reach the brightness of the moon seen on earth. But in the next few weeks, it quickly darkened, which means. In the distance, Betelgeuse may have exploded, which is because it is more than 640 light years away, so it will take us more than 640 years to really see the gorgeous scene produced by its explosion.

Of course, in the vast universe, our earth is too small, and there are many great forces that can make our earth disappear completely. But our earth is lucky enough. Our home planet, the sun, leads us to live in the suburbs of the Milky Way, far from the center of the Milky Way, with few stars. The nearest star is far away from us. There is also the distance, so that we are rarely influenced by other stars. And we need to be more worried about asteroids that often fly over the earth. They hit the earth at high speed. The loss is beyond our imagination. In the future, once there is an event that can really destroy the earth, then we humans may really go extinct. But by then, maybe we have achieved interstellar migration, or we have enough technology to deal with this disaster. This is Titan Studio. Thank you for reading.
