Are we alone in the universe?

A dog! They are looking at the stars in the sky. As we see. May or may not be breathing. Creating or not creating. But one question is right between them. Just like us. Are we alone in the universe? When the Armstrongs returned from the moon, they were quarantined for several days. Why? Because if a virus or any other germs came through them from the moon, i.e. very close to our satellite, scientists thought about the possibility of life in this satellite, isn't it strange? Let's go to the universe in search of life. Earth is the only source of life? This question is very old. There are ten thousand times more stars in our Milky Way alone than there are sand dunes on this planet. To be more precise, this number is ten to the power twenty-two to ten to the power twenty-four or more. If five percent of its stars are like our sun, then the number stands at five hundred billion billion stars. Very good talk. If we assume that even one out of every five Sun-like stars has water and life-creating chemicals. Then the number is one hundred billion billion planets. great


Do one thing. Let's cut ninety-nine percent from this one hundred billion billion. Assume that only one percent has a chance of survival. So how much did it cost? One hundred and one million planets. So where are they all? Nobel Prize-winning Italian, American scientist, M. Rico Fermio asked one day, that there are so many Earth-like planets that have the possibility of life. Where are they? If we are less intelligent than them, why are there no civilizations on so many planets? Our advanced intelligence accomplishes that. So why are they not communicating? The answer is hidden somewhere in the universe and time which is still unknown. SCTL has been trying for years to get a signal from the universe. Research has been going on for decades but the received signal is zero. Let's talk about this. In search of life, we ​​must first look at the basics. Whatever we see with our eyes is extremely complex. How is it possible to think that the question does not come because you are used to seeing it? Chemistry is necessary for the creation of life.


We are a vast storehouse of chemical reactions. Now, what is required for this reaction? First of all, energy is needed. Such as light, heat, etc. Just the right amount. This is why Venus or Jupiter do not have life because they are either too close or too far away from the Sun. Next, different chemical elements are needed. All planets have chemical elements. But the need is the material that creates the existence of animals. such as oxygen or carbon. And the need for the most useful liquid, why water? Because the atoms in the vapor-liquid cannot bond. Again on hard ice, they can not move. For this reason, even if ice exists on many planets, life does not exist. So evolution can definitely be needed. Looking at Earth we see that the first cells were probably born in hot volcanic water. In the language of biology, it was once impossible. What we teach can be prepared from basic and simple elements. It is not possible to throw away the alien theory made of a completely unnatural material. Because science still does not know much. Now let's look at the universe. Planets that are members of Earth are called exoplanets. So far scientists have found 3800 exoplanets. Kepler Six to F is one and a half times bigger than our Earth. Located twelve hundred light years away. There is a strong possibility of the existence of water on this seven billion-year-old planet. Trappist One D is forty-one light years away. Tea Garden B is twelve light years away. K to Eighteen B is located one hundred and eleven light years away. Each of these has the potential to contain water. Evidence of atmospheric water vapor has even been confirmed in K28B. We have only scratched the surface of the wonders of the universe.


Well, do you know Drake's equation? No no. There is nothing to fear. You will understand. Those who have watched the Cosmos TV series know that Call, Second, and his friend and fellow researcher at Cornell University explained this equation very simply. If you don't see it, you can see it. Abbreviated here N is the number of communication-capable civilizations in the universe. r is the birth rate of stars. SP is the number of stars around which the planet is orbiting. NE Average number of potentially habitable planets present in stars orbiting planets. FN is the number of all planets where life is likely. FI is the total number of planets that have developed life. A number of planets with civilizations possessing technology capable of transmitting radio waves into space are suitable for FC detection. A time when intelligent beings are broadcasting their existence to the universe to communicate. This formula has been debated for many years. Drake also gave the approximate value of this equation. Then came the solution of equation ten. That is, only in our galaxy at least ten communication capable, civilization is possible. Later NASA found the value of this equation to be two decimal three one. NASA thinks they are on the verge of a discovery. Who knows what that is? Brake's formula is a simple and easy representation so that it is possible to easily calculate the number of advanced civilizations by setting the values ​​of the variables. But so far it has not been possible for us to calculate that number. Because we don't know a standard. It is not possible to say that we will know in the near future. But the hope is that if one value is known, the way to extract other values ​​will be revealed. If the calculation of the hope of the Drake equation is true. And intelligent civilizations in the Milky Way galaxy can master wireless technology.


Then at least wireless communication with them is possible. If these civilizations were randomly distributed throughout the galaxy with a diameter of one hundred thousand light years, the distance to the nearest civilization would be about two hundred light years. That means that even at the speed of light it would take two centuries for a message to return from there. Radio Web is currently the only means of communication with the universe. Someday, a better medium will be discovered. Maybe then it will be possible to communicate or maybe not. In science, the possibility always leads to better thinking. But what is it really? If we find alien life they are less intelligent than us then maybe there is nothing to worry about. But if the intellect is advanced. But then there is a problem. Can the possibility be completely ruled out in our case for a race of people better than those who lost Neandertal? We are too busy. Actually, we are alone to see it. Time will tell whether it is good or bad. Maybe that's where science begins. Or who knows? Maybe end there.

Why the US government 30$ trillion owe?

  The United States is in a lot of debt. Currently the country owes $27.2 trillion. But who would even lend them that much money? Who does the US owe this massive sum?  Well, the answer to that is pretty simple. In large part, it owes itself that money, but there's also quite a few other countries it owes to. the US essentially owes two groups of people, the general public, which can be other countries or even investors in the US and itself. But before we get into who makes up those groups and what the percentages look like, first let's get some basics. Whenever the US government needs money, it raises that money through the issuing of savings bonds or treasury bonds. These bonds are basically pieces of paper that say the US will pay the person or agency that buys it back with a little bit of interest. Many people want to buy bonds because they're pretty solid investments, like banks, foreign governments, and maybe even you. The debt ceiling, which you may have heard about,...

Beijing's Foreign Ministry prophet Wang Wenbin stressed that Taiwan is an integral part of mainland China. There is no room for concession or concession. Encouraging Taiwan's independence would be like playing with fire. This is what Chinese President Xi Jinping said in 2021. still, there would be nothing to worry about, If the issue was limited to such a war of words. The constitution also has a law on Taiwan called the Anti-Association Law, which states that if Taiwan does not unite with China, also China is naturally obliged to intermediate militarily in Taiwan. multitudinous international relations judges believe that if there is a war between China and the United States in the future, Taiwan will be the flash point of th...

The End of Doller empire !

The End of Doller empire!  Saudi Arabia is in discussions with China to price some of its oil sales in yuan, but as ties with Washington continue to be strained. Beijing and Moscow are diversifying. China and Russia have taken another step closer towards dumping the dollar and agreed to trade in their respective national currencies, the Russian ruble and the Chinese yuan. The End of Doller empire Hi everybody. the US dollar has been the most powerful currency in the world for 80 long years.  This reserve currency status gives the United States such unprecedented power over the world economy that can cripple the economy of any country within a fortnight. And because of this power, it has even dominated giant players like Russia and China. But you know what guys? This is where China and Russia have actually come up with a master plan to kill the dollar dominance in the world. And if you look at the past 10 years data, you will see that it's actually working out quite well. In 19...

What is the meaning of the rate race?

It's complicate to calculate exactly when you joined the rat race. But rest assured you're in this race. Flash back the time of reading in class eight? Ahead of the education test computation Algebra figures doctoring all the complex formulas of wisdom Get up beforehand in the morning at the private instructor's house and study late at night. You must have spent a lot of time busy with work compared to your age? We all spent. At that time, the guardian must have said that this is a many further days. Life is peaceful and peaceful only when the education test is over. You have heard these words numerous times in numerous occurrences of life. Take the SSC test, you get freedom when you get to council. Life will be full of joy once you can get into varsity. Enter the job life formerly. Having fun with your own plutocrat is different. Have you heard of this?  Can you match the numbers standing at the end of the age clock? What do you think? Has life gotten a little easier after...

What is Obsessive Compulsive Disorder?

Depression has an additional air or disease in English which is called Obsessive Compulsive Disorder or OCD and in Bengali it is called Suchibai. Sounds like a very common disease doesn't it? We do not give importance to this disease because it is made fun of because it is considered normal. And on that occasion, this weed grows bigger. Pain increases and that pain is much more intense than depression. Obsessive compulsive disorder (OCD) is a common mental health condition where a person has obsessive thoughts and compulsive behaviors. OCD can affect men, women and children. Some people start having symptoms early, often around puberty, but it usually starts during early adulthood. Here is a detail view of OCD. According to the report of the World Health Organization, about 700,000 people commit suicide in the world every year. Ninety percent of these suicides are due to depression. People with Obsessive Compulsive Disorder or OCD may rarely reach the stage of suicide. But the life...

But let's take a closer look to figure out what exactly a meme stock Meme stocks are a fairly new term, and they spawned out of trading hype and hysteria from 2020 and 2021, with discussions of the stock originating on Reddit or other online forums. Meme stocks garnered and do garner so much attention simply because of how fast they rise for seemingly no reason. Typically a good stock would rise 30 to 50% in a year, but a meme stock could make that move overnight. ...

Who controls of our whole economic money?

  I'm gonna start this article with a quote. Henry Ford once said it is well enough that the people of the nation do not understand our banking and monetary system. For if they did, I believe there would be a revolution before tomorrow morning. I quote this because it encapsulates the fact that the contents of this article may be unsettling compared to the articles that I normally make.  I still feel compelled to make this article because I've been exploring the financial world for the last four years and it's definitely given me a more complete view of the world I want to share some of what I've come across with you guys. I'm also going to do a article about cryptocurrencies like Bitcoin in the future and to understand why Bitcoin and other cryptocurrencies may continue to rise. It's critical that you understand the contents of this article. I hope that you find this topic interesting and that inspires you to do your own research afterwards.  Now, with that sai...

Why money worth anything ?

  Money is arguably one of the most important things in the world. While happiness and joy might outrank it at least on your uplifting Instagram feed, money does seem to make things easier. When you actually stop and think about paper money, though, we're left with a perplexing conundrum. There's nothing inherently valuable about these banknotes, at least today. So why does money have any value at all? Over time? How paper money is valued has actually changed, so to understand how modern money is worth anything. First, we have to look back to the early days of paper money. In the early days of governmental currency, money wasn't paper. Rather, it was usually a coin made of a precious metal like gold or silver. The value of that money was intrinsic as the value of the metal that made it up. If you melted a gold coin down, you'd have the same amount of gold as the coin was worth. As this system of money became impractical, governments decided to come up with a new way of ...

What is post traumatic disorder?

Catherine is a working girl in a city. The house is quite far from the workplace. He has to travel by public transport. One day it was quite late to leave the office due to work pressure. He boarded a bus to go home. And just before the last stop at his house. Quite a lot of the way. So he put it on the seat. The eyes may have come from fatigue. When he opened his eyes he saw that he was the only passenger in the bus and a boy was standing next to the driver. He asked the driver if the bus will not go forward? The driver said he would go. The young driver told her to sit quietly, but the young woman felt that something unusual was going to happen. Much like the sixth Indra someone told him something is very bad. So he wanted to get off the bus. Then the driver increased the speed of the bus. of the young woman. Nothing left to understand. Hell may descend inside the bus within a short time. Something will happen to him that even in his worst nightmares.  The incidents of accidents ...
