Being one of the millions of advanced civilizations is undoubtedly an interesting idea, but the existential question haunts humanity throughout history and keeps recurring in their minds: Where did everyone go? As astronomer Carl Sagan says, if we were roughly pushed into the universe, we could forget that the chance of being close to a planet is less than one in a trillion.
Assuming that there are advanced civilizations in the universe, the author Bill Bryson estimates that the average distance between the two civilizations will be at least two hundred light years. Even though these creatures know we are here and can somehow see us through their telescopes, they still see the light that came out of the earth two hundred years ago. So she does not see me, she does not see you, she sees the French Revolution and those who do not know what nuclear is, and the people who make electricity by rubbing an amber wire with fur. Two hundred light years away from us. So even though we are not alone, we are alone in all practical senses.
Throughout human history, the idea that our universe is overflowing with other worlds we know nothing about and revolve around their sun has been a mere conjecture. At that time, astronomers could use their telescopes to think about distant stars, daydream, and wonder if there are other planets outside our solar system that are hidden behind the light emanating from the surrounding stars!
If we think a little bit about the fact that humans have been staring at the sky for decades, we can understand the bitter truth that the efforts of scientists have been taking some years too late. To detect very few signs that other worlds exist outside our solar system. Fortunately, 30 years ago, more advanced capabilities appeared, and days revealed to us that there are hundreds of exoplanets (around stars other than the Sun) in our galaxy “Milky Way”, the number of which is far greater. NASA, about 5000 planets.
In March of this year, NASA announced the simultaneous discovery of 65 new planets, bringing it into the archives of its outer planets, bringing the total number to 5005. In the same context, Jesse Christiansson, an astronomer at NASA’s Institute for Exoplanet Science at the California Institute of Technology, says: “These planets are never easy to find, the closest example is the desperate efforts of people hundreds of years old to discover anything.” For example, my latest search for exoplanets was not successful until I went to four different searches. “
The discovery of these exoplanets helped scientists to express some amazing ideas about the universe, as nature is capable of embracing all kinds of worlds of various shapes and sizes, some of which are smaller than Mercury and some twice as large as Jupiter. Some of them have a deadly cold climate, others have scorching heat, and their properties are between rocky worlds, while others are filled with gas and clouds.
Therefore, the more scientists study these planets, the more they confirm the vastness of space, because the closest of these planets is 4.2 light-years away from us, at the same time. Two thousand light years away from us. Based on what scientists have achieved so far from exploring the unknowns of the universe and some of its mysteries, they have now firmly discovered that our galaxy, the Milky Way, is filled with billions of planets.
The goal of astronomers is to find life on other planets they are looking for so far, but this goal has not yet been achieved. It is true that they discovered Earth-sized rocky planets, and the fact that they discovered their stars orbiting at a reasonable distance (far from freezing) is that in theory it deserves to become a habitable zone (that level is called the possible range).
Despite scientists’ expectations that the universe is filled with billions of worlds around us, it does include the possibility of life, and research has yet to reveal any evidence of the existence of life on other planets and has not received any messages or signals from them. Worlds that represent what forms exist. After a minute of life.
Astronomers can predict how many planets are outside our solar system, but they still cannot tell how far they will have to go to find other extraterrestrial life. Although there are more than 5,000 worlds besides our own, we are still alone. Suppose there were other beings, and the vast distances that separate us from them isolate us in every practical sense.
In the early nineties, scientists discovered the first planets orbiting stars other than the Sun, using ground-based telescopes to be able to capture oscillating stars as they rotate on their axis. In 2009, everything changed after NASA launched the Kepler study to search for planets orbiting stars other than the Sun.
The Kepler telescope was able to observe hundreds of thousands of stars, and also observed fading in the brilliance of some stars, indicating the possibility of a planet passing past it and blocking its brightness. The study completed its mission in 2018, leaving a huge record of finding two-thirds of the planets orbiting other stars outside our solar system, which is about 5005.
Over the years, the discovery of these exoplanets has caused scientists a mixed sense of joy because they can now at least identify these planets and easily list their names, although they do not seem to be the names of other planets. They appear as serial numbers: HD 209458, HD 18973 GJ 121. The discovery of hotter Jupiter, a class of giant gas exoplanets with similar Jupiter but shorter orbital periods, shakes the same. Ideas that make up the planet, breaking down conventional ideas that do not take into account these gaseous planets. Large across the wall.
Although some findings show that these exosystems with multiple planets are a little more familiar, they are a little weird. In 2017, scientists discovered seven Earth-sized planets orbiting a faint star called TRAPPIST-1 40 light-years away. It orbits for only about 20 days.
Theoretically, this distant system could be habitable because its three planets are definitely in the habitable zone (i.e., at a suitable distance, not near or far from the star). It is true that astronomers do not yet know the nature of the atmosphere of these planets, but they will soon receive data from NASA’s new James Webb telescope, which could pick up some particles that could actually confirm the existence of life on other planets. Or not.
Through the study of these planets, scientists find that the characteristics of the Earth are very rare, the closest evidence to this is that we have not yet discovered an Earth-like planet, and we have not found a rocky planet in these years. Water the size of our planet Chemical atmosphere and the right temperature for water to flow across the planet without boiling or freezing.
But this is not possible due to the type of flu-like characters that explore and monitor aliens, and they want to find life on other planets that are limited to microbes, but rather to find their primary goal. Advanced civilizations. Every time the SETI Institute (a body aimed at searching for creatures other than Earth) astronomers find a new planet, they rush to point their telescopes at the star orbiting this planet. For Earth, there may be another planet hidden within this system.
From this point on, we now realize that if a greater number of exoplanets are discovered, scientists are more likely to continue their search, and new missions are expected to increase with the intensity of ground and space telescopes in the coming decades. So the most important question here remains: Will the discovery of nearly 5,000 or 10,000 or 20,000 planets outside our solar system give a satisfactory answer to the existential question that haunts us? Will this help find out if there are life on other planets? In fact, the answer to this question is not related to the size of our devices or the extent of their development, but rather to the universe itself, and how common life is in it.
It’s like throwing a dice, the more likely you are to roll the dice, the more likely you are to collide on a life-supporting planet. Of the 100 billion planets in a galaxy, only our planet could have had the chance to live on Earth, so we always wonder where everyone went? Why are we still alone in this vast universe? In fact, the more planets there are, the more confused we are and the less likely we are to be close to a habitable planet.
Eventually, astronomers will continue to search for many planets outside our solar system, motivated by the hope that they will find any kind of life on these planets because they believe that life on a galaxy of this size is full of billions. What do the current figures indicate that life is most common on stars and planets. A decade later, the number of confirmed planets in the Exoplanets’ archive will double, during which time we may roll the dice again and again, holding our breath and fearing what the unknown will hold for us.

According to the Associated Press, many Americans joke about how bad they are at math, and their already poor scores on standardized math tests continue to decline.
Employers say America needs math geniuses like animated movies need superheroes. They believe America’s poor performance in math is no laughing matter, but a threat to national security and global economic competitiveness.
Jim Stigler, a professor of psychology at the University of California who studies the teaching and learning process in subjects including mathematics, believes that the technological advances that will lead the world in the next fifty years will come from other countries. Capital that America does not have.
The U.S. Department of Defense has called for a major effort to support education in science, technology, education and math, or “STEM” for short. The number of graduates in these categories in China is eight times that of their counterparts in the United States, and the number of engineers in Russia is four times that of those in the United States, he said.
For his part, Aspen Research Institute Vice President Josh Weiner says the matter is not just an academic issue. Last July, he warned that other countries, particularly China, were challenging America’s technological dominance. He explained that mathematics is needed to solve the fundamental challenges faced in the present era.
On the other hand, the number of jobs in mathematical occupations, i.e. jobs that use the dream of arithmetic and use advanced methods to perform calculations, analyze data, and solve problems, will increase by more than 30,000 per year. In the current decade, that’s the fastest rate compared to any other type of job, according to the U.S. Bureau of Labor Statistics.

Concerns about the power of the next generation of controversial artificial intelligence technology are growing in Britain, between its supporters and detractors, from criminals and terrorists using the technology to achieve their goals, to frequent scenes in sci-fi movies. About a machine escaping human control.
The UK is hosting a summit on AI security in November, and British officials are touring the world ahead of the summit.
According to The Guardian, fears are widespread that criminals or terrorists could use artificial intelligence to accomplish their extremist goals and cause mass death, and some around British Prime Minister Rishi Sunak worry that the technology will soon become powerful enough to help. Individuals develop biological weapons that are out of bounds.
“The purpose is to warn against this,” said a person familiar with the summit talks Artificial Intelligence Risks“Downing Street is paying attention at the moment.”
Frontier AI is a term used to refer to models of artificial intelligence that are dangerous enough to endanger human life, the newspaper noted.
Sunak warned months ago about the dangers posed by artificial intelligence and urged the international community to adopt safeguards to prevent its misuse.
Recent developments in artificial intelligence technology have raised fears among officials. Last year, an artificial intelligence tool was able to suggest 40,000 different potentially lethal biomolecules, some of which were similar to VX, in just 6 hours. .
Earlier this year, researchers found that ChatGPT can lie to a human to achieve a specific goal. The AI-powered chatbot convinced a person to solve a “captcha” tool designed to take down online bots after telling them to a human. Visually impaired and needs help accessing the website.
Government sources fear that a criminal or terrorist could use artificial intelligence to help prepare the components of a biological weapon before sending them to a lab, where they can be mixed and shipped without any human supervision, a risk some believe will soon increase dramatically. , companies are already spending hundreds of millions of pounds. Sterling is looking for more powerful processors to train the next generation of AI tools.
Another concern is the emergence of “artificial general intelligence,” which refers to an artificially intelligent system capable of autonomously performing any task at or above human level—and which could pose an existential threat to humans in years to come.
On the other hand, the existential risk approach to general AI has been criticized by AI experts, who argue that the threat is overstated. Last week, a senior tech executive told US lawmakers that the notion of uncontrollable public AI was… “fiction”.
Several world leaders, including Canadian Prime Minister Justin Trudeau and French President Emmanuel Macron, are expected to attend the summit. The UK has invited China to participate.
The British government confirmed that the summit would focus on risks such as the misuse of artificial intelligence to develop biological weapons or electronic attacks, and the emergence of advanced systems that escape human control.
He said in a statement: “There are two areas that the summit will focus on in particular: the risks of misuse, for example when new AI capabilities help a bad actor in biological or cyber attacks, and the risks of losing control. The risks may arise from the advanced systems we want to “counter it”.
Sunak warned months ago about the dangers posed by artificial intelligence and urged the international community to adopt safeguards to prevent its misuse.
Downing Street is reportedly spending £100m on a new artificial intelligence team. The United Kingdom to evaluate them before using them more widely. .
A Downing Street spokesman said AI has “huge potential to transform every aspect of life and the Frontier AI Taskforce has been established to ensure technology is developed safely and responsibly”. Potential risks.
