How Big Is the Universe¿ 🌌 ¦ The Size of the Observable Universe Explained

Do you know that we live in a universe They can see only that part of it. whose light has yet to reach us But the question is, how big is the universe really? And is there any limit to it at all? We live on Earth, which orbits the Sun. The Sun is just one star among the billions of stars in our Milky Way galaxy. And in the celestial sphere, there are stars of the Arabs. The astonishing thing is this that our entire Milky Way is also just a very small part of the universe Today we start from Earth The Sun is the center of the solar system. And then they will travel to the observable universe. In the end, we will also know this What do scientists say about the actual size of the universe? Number one: How small is the Earth? The ground feels extremely vast beneath us. Yet, compared to the universe, this is extremely small. The diameter of the Earth is approximately 12,742. It is 12,742 kilometers. If you compare the volume of the Earth to that of the Sun The sun is so big. about 1.3 million inside it Up to 1.3 million people can be accommodated in the land area. And the sun is not any large star in the universe either. Our solar system is on number two The planets, including Earth, revolve around the Sun. We call this entire region the Solar System. The average distance from the Sun to the Earth is approximately 150 million kilometers. That is 15 kilometers and the time it takes for light to travel from the sun to the Earth About 8 minutes 20 seconds It takes 8 minutes and 20 seconds. When we look at the sun You actually see the Sun almost 8 minutes ago. You are looking at the state from 8 minutes ago It is this very thing that helps us understand the average of the universe. It comes to the third floor. What is the year of light? The distances in the universe are so vast. It becomes difficult to express them in kilometers. That's why the scientist Noury Sal Light Air is used A light-year is the distance It's a light that one sees almost once a year. Think Light in one second It can orbit around the Earth nearly seven and a half times. It's on number four. This is the national flag of Keshan. Now we are moving far beyond our solar system. Our sun is part of the Milky Way galaxy. Malkee Way is a very large cake. In which hundreds of Arab stars may exist One orbit around the center of the Milky Way galaxy for our Sun Nearly 23 crores to complete It could take up to 230 million years. Since dinosaurs have existed on Earth During this period, our Keshan was on its journey. It's on number five. Were the Mlecchas the entire world? No This might be the most surprising thing about this video. Malki Way is only one of the many. Scientists have observed countless other galaxies through telescopes. In each of them, there are crores of Arabs. There could be even more stars than that. Some are so far away from us. It took the Arabs seven centuries for their light to reach us. Number six is located in Kabul observation How big is the universe? Now let's get to the actual question. How big is the universe? According to scientists, the observation of Kabul The diameter of the universe is approximately ninety-three It means that the Arab Spring has been a year. It is very important to understand one thing here. The age of the universe is approximately 13.8 It means 13.8 billion years. Observing the Universe at Ninety Three That is the Arab Nourie year. How can it be wide? The reason is the expansion of the universe. As the light was traveling toward us This self-destruction continued to spread. That is why today, the most remote regions The current distance could be several times greater than this distance. What light had illuminated the journey? Number seven is with me. Is the entire universe Ninety Three? Is it really just the Arab Noury year? Here is the answer. We don't know. Ninety-three billion years The size of the universe is not finite. rather, the observable universe It's a small diameter. Perhaps the entire universe It's much bigger than this. And in some scientific models This possibility also exists. that the entire universe could be infinite It means we don't know this. at the end of the universe A wall by the side There is a final place available. Yes or no? It comes at number eight. Why is the universe expanding? Approximately 30.8 Arab years 13.8 billion years ago The universe is extremely hot. She was in a state of confusion. This task is generally Bing is called It wasn't like that. inside the khala There was an explosion. And other things spread out in the empty space. Rather, the veil itself was spreading. That's why such distant harvests They keep moving away from each other. It comes at number eight. Does the universe have a center? Another interesting question is this one If the universe is expanding Where is its center? According to the current cosmological model The expansion of the universe No one is coming from a particular center. toward which we could point As a simple example Imagine the surface of a fog. With points made on it When the dust blooms You move away from each point from the other point. The universe is more complex than this example suggests. However, understanding the spread of this notion Data is being provided. Is there a us in the universe? Is there life elsewhere besides Earth? The question is also very interesting. Because in the universe there are countless Stars and planets exist. A scientist on another planet Possible consequences of life Trying hard But so far, apart from the Earth A place for the preservation of land Left, not discovered. That is why we cannot say with certainty that we are in the universe Are they alone or not? It comes at number nine. How much of the universe can we see? This is also an undeniable fact. our most powerful telescopes It cannot see the entire universe either. We can only see the observable universe. The light from areas outside this one We haven't reached you yet. Due to the expansion of the universe Not observable by us This means that That part of the universe As we can see Perhaps the entire universe Spending is a part. At the end, once again, a question How big is the universe? We know that it is observable. The universe is approximately ninety-three Tiranowe Arab Nuri keeps a candle burning all year. But the entire universe It could be bigger than this. And possibly also Its full stature is above. We could never obtain a definite answer. Our land Sun System Solar And the king's servant, the eunuch In this great universe It is only a very small part. Perhaps the universe's The most astonishing thing is this No, not how big she is Rather, this is what it is: About it, we How little you still know If you are amazed by such a I like information.
