If 6 months later, this giant asteroid really hits the earth, is there any way for humans to avoid danger?
Giant Asteroid Really Hits Earth
We all know that during the evolution of the earth, there have been many mass extinction events caused by asteroids hitting the earth. The closest one to us is the fifth mass extinction that occurred 65 million years ago. Extinction, then, will a similar catastrophe occur on Earth in the future?
NASA simulated disaster warning: humans have only 6 months left
Some time ago, NASA and scientists from many times around the world jointly conducted a simulation experiment. The theme of this experiment is: a giant asteroid was discovered about 35 million miles away from the earth, and it is moving towards Flying towards the earth, in about 6 months, it will hit the earth, what should we do?
Judging from the time reserved in the simulation experiment, it seems that there is still plenty of time. However, this does not mean that humans can escape, because there are many settings in this experiment.
For example, for this asteroid that is about to hit the earth, there is no way humans can prevent it from hitting the earth. The only thing we can do is to make some related preparations on the earth.
So, what should humans do? The researchers believe that even if there are still 6 months left before hitting the earth, humans are powerless. Whether human civilization can continue depends entirely on their luck. At the same time, it also depends on the final landing of the asteroid. where is the location.
Of course, if it is big enough, even if it falls in no man's land, the entire ecological environment and climate environment of the earth will fall into a "dark period" lasting tens of thousands of years through a series of chain reactions triggered by the huge power after the impact. Among them, human beings may not be completely extinct, but human civilization may be interrupted because of this.
How long in advance of warning is enough for human beings to be fully prepared?
Over the years, NASA has conducted 5 related simulation experiments. The results show that if humans want to take precautions in advance, it will take at least 10 years.
That is to say, when we find that an asteroid has the risk of hitting the earth, in order to avoid disasters, we need to make early warnings and precautions 10 years in advance, so that human civilization will not disappear because of this.
So, in these 10 years, what do humans need to do? First step: know your enemy. The researchers said that in the first stage of this 10-year period, humans need to try to get close to it and get detailed information about it, such as how big and wide it is, and what is it made of? If it hit the Earth, where would it most likely land?
If it is more than 500 meters in diameter, it means that if it lands in a densely populated area, then an area the size of France will be completely destroyed.
Secondly, it is necessary to observe its trajectory to determine where it is most likely to collide with the earth, and this process will take at least 5 years.
In the end, it is to find a way to eliminate it. With a 10-year disaster warning in advance, in the absence of other disasters, it is possible for humans to destroy this asteroid in space, or to make it through space impact. Its forward path deviates, and from colliding with the earth, it turns into a brush with the earth.
Now, NASA has decided to conduct space experiments. In the fall of next year, NASA plans to launch an asteroid defense weapon to destroy a near-Earth asteroid in space. If it is successful, it will also mean the ability of humans to avoid space hazards. will be greatly improved.
How many near-Earth asteroids harm Earth?
In terms of quantity, the number of near-Earth asteroids discovered by scientists is about 20,000, and these are only the number of near-Earth asteroids that threaten the earth through observation and research, and the real situation is even more.
Among these near-Earth asteroids, there are more than 2,000 near-Earth asteroids with a diameter of more than 1 km, which means that if any of them hits the earth, it will plunge the earth into a devastating catastrophe.
And even larger, there are hundreds of giant asteroids that will directly destroy human civilization, which means that there are a large number of time bombs around the earth, and no one knows when they will hit the earth. The current level of human science and technology is only to closely monitor them, and even so, there are still many fish that slip through the net.
So, is the Earth at risk of being hit in the future? The answer is yes, in 2004, scientists discovered an asteroid with a diameter of about 332 meters, which will hit the earth in about 2036.
Although through research in recent years, scientists believe that the probability of it colliding with the earth has been reduced to one in a million, but this does not mean that humans are safe, and it may still collide with the earth.
You must know that if an asteroid with a diameter of 40 meters falls, it may destroy a city. It is conceivable how powerful an asteroid with a diameter of 332 meters is. Do you think humanity will be destroyed by an asteroid impact in the future? Welcome to leave a message and tell us your opinion!

NASA predicts: Asteroid may hit the earth many years later, and its destructive force is unprecedented
In 1994, at a distance of hundreds of millions of kilometers, the Shoemaker-Levy 9 meteorite collided with Jupiter, starting a desperate collision between heaven and earth, which shocked biologists with sweat. The tremendous kinetic energy caused by this impact is equivalent to 2 billion nuclear bombs. Okay, it hit Jupiter, and everyone just sat on the mountain and watched the tiger fight.

Microbiota, microbiome or microflora: how to speak correctly and why it is for health.
You've probably heard the phrase, "We are what we eat." But modern science says more precisely: we are also those who live in us. Until 2016, it was believed that there are many times more bacteria in our body than our own cells. The latest calculations by mathematicians show that we divide the body with our microorganisms by about 50/50: about 30 trillion of our cells versus 38 trillion bacterial ones.

Chinese EVs Closing In on America After Canadian Tariffs Deal
The electric vehicle race is no longer just about climate goals or consumer choice — it has become a geopolitical contest. And in early 2026, a subtle but powerful move by Canada may have tilted the board. By agreeing to sharply reduce tariffs on Chinese electric vehicles, Canada has opened a door that the United States has worked hard to keep shut. While Chinese EVs are still largely barred from the American market, they are now edging closer than ever — not by crossing the border directly, but by entering through Canada. This development raises a pressing question: Are Chinese EVs closing in on America, and what does that mean for the future of North American auto markets? The Deal That Changed the Game Canada’s new agreement with China allows up to 49,000 Chinese-made electric vehicles per year to enter the Canadian market at a tariff rate of just over 6%, a dramatic drop from the previous 100% tariff that effectively blocked them. On paper, the quota seems small. In reality, it carries enormous symbolic and strategic weight. For years, both Canada and the United States aligned closely on keeping Chinese EVs out, citing concerns over unfair subsidies, national security, and the protection of domestic auto industries. This new deal marks a clear shift — and a divergence from U.S. policy. Canada didn’t make the decision in isolation. The EV tariff reduction was part of a broader trade reset with China, tied to agricultural exports such as canola and efforts to stabilize a strained economic relationship. Why Chinese EVs Matter So Much China is the undisputed leader of the global electric vehicle industry. Its manufacturers produce EVs at scale, often at prices Western automakers struggle to match. Brands like BYD, Nio, and Xpeng have already expanded aggressively into Europe, Southeast Asia, and parts of the Middle East. North America has remained one of the final fortified markets — until now. Chinese EVs are appealing not just because they’re cheaper, but because they’ve rapidly improved in quality, range, and technology. For consumers priced out of North American and European EV models, Chinese vehicles offer something rare: affordability without sacrificing features. Canada’s decision gives Chinese automakers their first legitimate foothold in North America — and footholds tend to grow. Why the U.S. Is Nervous The United States still enforces a 100% tariff on Chinese EV imports, making them effectively unsellable in the American market. But Canada’s move has triggered concern in Washington. U.S. officials argue that Chinese EVs entering Canada could indirectly pressure American markets, influence supply chains, and weaken Washington’s leverage in future trade negotiations. There’s also a political dimension. Both major U.S. parties have framed Chinese dominance in EVs as a strategic threat — not just to auto jobs, but to technological leadership. Modern EVs collect vast amounts of data, and lawmakers have raised concerns about cybersecurity and foreign data access. While Chinese EVs aren’t rolling onto American roads yet, their presence just across the border changes the conversation. Canada’s Risk — and Opportunity Inside Canada, the reaction has been mixed. Automotive hubs like Ontario worry that opening the market could undermine domestic manufacturing and strain relations with the U.S., Canada’s largest trading partner. Some leaders have called the deal “lopsided,” warning it could cost jobs if American retaliation follows. Others see opportunity. A more competitive EV market could lower prices for Canadian consumers and accelerate EV adoption. It may also attract Chinese investment into Canada itself — including factories, battery plants, and supply chain partnerships. If Chinese automakers choose to build in Canada rather than simply export to it, the country could position itself as a bridge between Chinese EV innovation and North American demand. That balancing act — between economic opportunity and political risk — defines Canada’s strategy. Are Chinese EVs Really ‘Closing In’ on America? For now, the answer is: not directly — but strategically, yes. Chinese EVs sold in Canada won’t automatically flood the U.S. market. Regulations, trade rules, and tariffs still stand in the way. But proximity matters. Supply chains overlap. Consumer awareness spreads. Manufacturing footprints expand. There’s also the possibility of a workaround: Chinese companies could eventually build EVs in North America to bypass tariffs altogether. This idea has already been floated — but it faces fierce resistance from U.S. lawmakers and unions. Still, history shows that once a global industry leader gains regional access, momentum often follows. What This Means for Consumers For Canadian buyers, the impact could be immediate: more choice and lower prices in an EV market that has long been criticized for being expensive and limited. For American consumers, the effect will be indirect — at least at first. But increased competition could eventually pressure U.S. automakers to reduce prices, improve features, and accelerate innovation. The larger question is whether North America wants competition or insulation — and how long insulation can realistically last in a globalized EV economy. The Bigger Picture: A Global EV Power Shift Canada’s tariff deal reflects a broader reality: China’s dominance in electric vehicles is reshaping global trade, whether governments like it or not. Europe is already grappling with an influx of Chinese EVs. Emerging markets are embracing them. And now, North America has its first real crack in the wall. This isn’t just about cars. It’s about who controls the future of clean transportation, supply chains, and industrial policy. Final Thoughts Chinese EVs aren’t driving down American highways yet — but after Canada’s tariff deal, they’re closer than ever. This move doesn’t spell immediate disruption, but it does signal a shift. One country has decided that economic pragmatism outweighs political alignment. And in doing so, Canada may have opened the door to a new phase of EV competition in North America. Whether that door swings wider — or slams shut — will depend on how the U.S., automakers, and consumers respond. One thing is certain: the EV race just entered a new chapter.
