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.

What is a meme stock? How does work a meme stock ?

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,

How is money created in modern monetary system?

Who controls all of our money? I'm going to focus on the United States and this article only because they're the world reserve currency , but everything in this article affects it.

Introduction of the modern monetary system Around the world today, we see central banks printing money. So here's a question. We're told from a young age that money is hard to come by. We should study to work our whole life to earn it. How then, can all this money suddenly come from nowhere?

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 pu

What are penny stocks in the financial market?

What are penny stocks in the financial market?  If you're looking to make some big returns on the stock market, penny stocks might be the way to go. But there's some of the riskiest investments you can make, and you have just as much chance at losing all of your investment by purchasing them. What are penny stocks in the financial market?  Penny stocks are typically stocks of small companies that trade for less than $5 per share, often even under $1.00 per share. Penny stocks sometimes trade on larger exchanges like the New York Stock Exchange, though most trade over the counter through private trading groups. One might look at penny stocks and think, well, if this $0.50 stock goes to a dollar, I'll quickly double my investment while this is true just because of penny stock. Is cheap does not mean that it is a good investment?  Generally speaking, penny stocks trade very infrequently, meaning that when you do want to sell, it can be hard to find a buyer.
