Will the solar system be okay? Scientists discovered that a star is flying towards the solar system!
Andromeda will collide with the Milky Way in 4 billion years. This is almost an undecided fact. Human beings are unable to reverse the arrangement of the universe. But what's even more worrying is that scientists have discovered a wandering star heading straight for our solar system. If these two stars collided, it could mean the end of all life on Earth.
Wandering stars, as the name suggests, wander in space and have no fixed residence. They do not belong to any specific galaxy. Or rather they were, only to be ejected from the system at some point by a supernova or two galaxies hitting each other. Whatever caused these stars to fly away under the gravitational pull of the original galaxy, they were launched at very high speeds. Why?
It's very simple. For example, in order to escape from our own Milky Way galaxy, stars need to move at a speed of 550 kilometers per second to escape the constraints of huge gravity. Fortunately, our sun only moves at a speed of 200 kilometers per second, not fast enough to become a wandering star. But these wandering stars are not uncommon. They may even account for half of the 2,000 trillion stars in the universe, and scientists have discovered that one of them may be heading towards our sun.
This star, which scientists call Gliese 710, will orbit close to our solar system in about 1.3 million years. When Gliese 710 finally reaches us, it will enter the Oort cloud, the outermost layer of our solar system, at a speed of approximately 51,500 km/h. Once it reaches Neptune , the epic countdown to collision will begin, by which time it will still be 10 years away from hitting the sun. At that time, humans had better make full preparations for the coming doomsday and plan their final lives. Of course, 1.3 million years later, the presence or absence of humans may be a problem.
In short, Gliese 710's gravity will disrupt the orbits of our planetary neighbors, causing stability between the planets to collapse and eventually drift. This could push Earth out of the habitable zone. Or, it could turn us into a wandering planet, after being inadvertently ejected from the solar system. Of course, more people are curious about what the collision between Gliese 710 and the sun will look like ten years from now.
Simply put, things will only get worse as time goes by.
One possibility is that the Sun and Gliese 710 will merge into a red nova, which would cause a violent explosion that would release nearly 500,000 times more light than the Sun currently emits. Considering the time it takes for light to travel from the Sun to Earth, you could be completely unaware of this devastating explosion for 8 minutes. But when humans discover all this light, humans may become blind within a millisecond, and then instantly kill humans on the spot. That's because behind this dazzling light would be super-hot gas, and this heat wave could be powerful enough to destroy almost anything in its path.
Starting from the disappearance of Mercury, then to Venus, and the Earth, our atmosphere and oceans will be completely destroyed, turning our planet into a barren rock. The explosion will also produce a large number of high-energy neutrinos , which will annihilate animals and plants at high temperatures. The earth will also be enveloped in deadly ultraviolet and gamma radiation, and even if humans manage to survive the explosion, they will not survive the harmful effects of all this radiation for long, and human eyes, skin, and even DNA will be damaged.
And now, if an alien species uses a powerful telescope to observe all this from a distant galaxy, they will see a bright star surrounded by an excess of red gas, and the infrared light left after the explosion will last for a long time. Visible for some time. But this is not the only way out of all this, there is a more peaceful alternative.
If the two stars move a little slower relative to each other, they may eventually merge into a massive new star as they orbit each other. Our sun will strip mass from its smaller companion star, Gliese 710, and eventually swallow it. Then this extremely hot and bright star would be called a blue giant. While this may sound many times more peaceful, this choice could still mean the end of life on Earth. Since our sun is now a massive blue star, the habitable zone of our solar system will be pushed even further.
Of course, this star is currently only flying in our direction. During the process, it encounters the gravitational pull of other galaxies and may change its direction. So do you think this star will hit the solar system? Will the solar system be okay? Welcome to leave your opinions!
