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,...

China is playing with peril. still, America will intermediate militarily to cover the island, If China invades Taiwan. This is what US President Joe Biden said during a meeting with the leaders of the Quintet in Tokyo on May 23. China is not sitting still. 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 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 a stock split?

When you enjoy stock in a company, you enjoy a portion of the company itself. When that company makes further plutocrats and the stock price goes up, you can make plutocrats by buying and dealing with the stock.  But what happens when the company decides to do a stock split? And why would a company indeed want to resolve their stock in the first place?  Stock splits are when a company divides the share of its stock into a multiple of generally two or three, but it can go as high as 100 or indeed 1000. So if a company had 1000 shares on the request, a stock split would turn those shares into 2000 or 3000 shares generally. And if you possessed one share at the time of A2 for one stock split, you'd all of an unforeseen own 2 shares of the company but the price would also be cut in half. unyoking a stock does not add any value innately. It's not a way for companies to just double their request cap. So why would companies do this just for fun? Well, unyoking a stock and therefore p...

Why do Bangladeshis hate India?

The liberation war is going on in December 1771. India didn't share directly in the emancipation war. They're conducting political conditioning on behalf of Bangladesh. About one crore deportees have taken retreat in India. The temporary headquarters of the Mujibnagar Government has been set up in Kolkata. The freedom fighters bivouacked in the border region of India and attacked the Pakistani army from there.  On the autumn of December 3rd, the also Chief of Army Staff General Shyam dialled the Chief of Staff of India's Eastern Army, Lieutenant General Jack Jacob. Manik told Jacob to tell Prime Minister Indira Gandhi that Pakistani aeroplanes have bombed fields in the western part of India. Indira Gandhi decided incontinently. India declared war against Pakistan.  Indira Gandhi's government honoured Bangladesh as an independent country on December 6. Bangladesh has completed fifty times of age. Bangladesh's relationship with India is fifty times old. But in the las...

What is Algorithmic trading as well Arbitrage trading? How does it works?

This stock request can be, if Coracias, beast to those that do not understand it, but currently you do not indeed need to understand it to make a plutocrat. The rise of the digital information age and AI has brought about a new way of stock trading called algorithmic trading. occasionally appertained to as automated trading or black box trading. This is basically a program that can trade stocks at high pets and frequency impeccably in line with the request. These programs are given constraints and instructions like timing, price, quantum, et cetera. And a stoner can OK tune how exactly they work. So how does it work also? Let's take a look. Take for illustration an average dealer. They buy 50 shares of a company. When the 50-day moving average goes above the 200-day moving normal. This is basically a specialized index that the stock is due to rise in the short term. also the same dealer would vend that stock when the 50-day moving average goes below the 200-day moving normal. Or th...

What is infinite money glitch? How does work fractional reserve banking system ?

  What if I told you that the entire modern financial system functioned on an infinite money glitch where billions, no trillions of dollars were created out of thin air day after day, and at any point the whole system could collapse? Oh, you. You wouldn't be surprised.    But what I just said was the truth, and it's something called fractional reserve banking, otherwise known as the Infinite Money glitch. Here's how it works.  When someone deposits $1000 in the bank, the bank does not hold on to all of that money. Rather, the bank will just keep 10% a $100 as reserves and then loan out the rest or $900 to other people or companies charging interest on the loan. Making additional money for the bank, the Lendy, or the person that took out the $900 loan then goes on to spend that money. To simplify the scenario, we'll say that that person with a $900 loan immediately paid someone else that $900. At this point, when looking at this small financial system, there's a tota...
