Looking Up At The Stars Is The History Of The Universe
How big is the known universe now? 46.5 billion light years in radius. That is, 93 billion light years in diameter. This area is known as the “observable universe” [1].
In fact, we can’t really observe beyond 46.5 billion light years. We don’t even know exactly what the boundaries of the universe are. The radius of 46.5 billion light-years is calculated.
We all know that the age of the universe is 13.8 billion years. Theoretically, we can only see up to 13.8 billion light years away. The farthest galaxy we have observed so far is about 13.3 billion light years away from us [2].
The oldest star we have found, with an age of about 13.7 billion years, is called Methuselah [3] (Methuselah is the longest-lived biblical figure).
So why do we see 46.5 billion light years away?
This requires an understanding of our perception of the universe. It was 400 years ago that man first used a telescope to actually look at the universe. In 1609, Galileo used a homemade 33x telescope to see the moon, and saw the moons next to Jupiter [4]. Galileo realized that it was possible that the Earth was not the center of the universe. He made the first human telescope, with a diameter of only 4 cm. The function of Galileo’s telescope is probably similar to that of a toy telescope nowadays. Modern people cannot use this low configuration of the telescope to see Jupiter. This means that ancient people have very good eyesight.
6500 years earlier than Galileo — the Sumerians. With the eyes to see the nine planets directly [5]. The ancient people of China, 2000 years ago in the Zizhi Tongjian have a record of Jupiter.
When we look up at the stars, all the stars appear to be twinkling, seemingly similar, but in fact they are different. The stars that are far away from us, it will take longer for its light to reach us. So the stars we see are the stars of the past.
For example, when we look at the moon, it is the moon of a second ago. When we look at the sun, it is in fact the sun of 8 minutes ago [6].
The stars at different distances, some are decades old, some are hundreds of years old. When you look up at the stars, all of them are the “history” of the universe. The history of the entire universe is written on the sky. If the entire starry sky is the history of the universe. We should see one thing:
The Big Bang
We should be able to see the explosion of the universe in a single moment. If the Big Bang was exactly 13.8 billion light years away, and the universe has existed for 13.8 billion years, its light should have reached Earth for the first time by now. So we should be able to see the Big Bang from the sky for a moment. Then why can’t we see it?
Actually, we can see it. It just took too long for it to fly over, and the light was too weak. The naked eye can no longer observe. But the machine can detect. This is called the “cosmic microwave background” [7].
The first detection of the “cosmic microwave background” in 1964, also verified the birth of the universe, indeed, began with the Big Bang. The Big Bang has been captured on film. We should be able to capture the arrival of Anunnaki on Earth as well [8]. If we want to see if Anunnaki came to Earth 6500 years ago, we can go to a planet 6500 light years away from Earth and observe the Earth with a telescope. At this point in time, the observation is 6500 years ago on Earth. So compared to the planet 6500 light years away, we are in their future.
And conversely, we can look at a planet 6500 light years away and also observe the history of that planet 6500 years ago. They are also in our future. We are in each other’s future. We are seeing each other’s past.
We see the entire universe as the past. And the aliens are observing the Earth from a distance, and they are seeing our history. Neither of us can see the future of the other. We are all living in each other’s future.
