Is 93 billion light years away the edge of the universe? How can we reach the edge of the universe?

We may often see that the diameter of the universe is 93 billion light-years, and then may have such questions:What is 93 billion light-years away? Is it the edge of the universe? In fact, the answer is simple:93 billion light-years away is our universe. However, some children are not happy to answer this way. Since it is still our universe, why is it said that the universe is 93 billion light-years away? This starts from the origin of 93 billion light years.

Find the end of the universe? Photos taken by the Hubble Telescope and found something wrong

Hubble has found the end of the universe? In Einstein’s time, physics was a bit earthy. At that time, some people were measuring”ether”, thinking that there was ether outside of the earth. As long as the ether can be measured, the center of the universe can be found. Possibly, the theory of relativity reveals that space-time influences each other, and Newton’s absolute space-time does not exist (or is not perceived).

The discovery of the largest structure in the universe, which is 10 billion light-years, changed the perception of scientists

There are many celestial bodies in the universe. From our point of view, the earth is a huge planet, with a diameter of 12,756 kilometers and a circumference of 40,000 kilometers. We drove at high speed, and it was not more than a thousand kilometers a day. However, Jupiter’s volume is the earth. 1000 times the size of the Sun, 1.3 million times the volume of the Earth, there are hundreds of billions of stars like the Sun in the Milky Way. The diameter of the Milky Way is known to be 160,000 light years, but in the observable universe, galaxies like the Milky Way are There are trillions of them.

Another giant structure found in the universe:like a wall, spanning 1.4 billion light years

A few days ago, a research team from abroad made another amazing discovery:a super structure called”Antarctic Wall” was observed. The super structure contains hundreds of thousands of galaxies, like a thick wall, traversing the universe In the middle, the span exceeds 1.4 billion light years, which is another giant structure discovered by astronomers after the famous”Sloan Great Wall”.
