Size of universe 93 billion light years wide ! We are How many Dwarfs in front of the endless space! Just how big the universe is diffused? Is there a limit? Can we measure its size? Such questions have always attracted the human brain. Yet we did not have any strong and logical guess how big our universe. After years of scientific research and labor, Now Scientists are in a position to say that how big is our universe.
According to Recent Research
According to new research our universe is 93 billion light-years wide. A light-year is a unit of distance which is used in the space where the distance is very long. It is the astronomical distance that light can travel in one year. Light moves at a velocity of about 300,000 kilometers (km) each second. One light-year is equal to 9,500,000,000,000 kilometers.
What is our status !
Our solar system is a small part of the Milky Way. Our Milky Way galaxy has 200 billion suns(stars). The solar system where we live, it has eight planets, many asteroids, and satellites. The latest estimates that there may be 100 to 200 billion galaxies in the Universe. This is only guessing. The actual number of galaxies may be 10 times more than we’d estimated. In the Endless spread of the universe, our Earth existed the same as a drop in the Ocean. Today the human population on Earth is just over seven billion. Along with the human, many types of trees, plants and animals inhabit here. Amidst all these, in the great expanse of space, our own existence is as sand particles in the great desert.
how much big our Universe
In the early 20th century that scientists have differed on how much big our galaxy. Harlow Shapley, American scientist said that our galaxy “Milky Way” is about three million light years wide. While Heber Curtis considered our galaxy is only 30 thousand light-years wide. But today, scientists agree that our galaxy is 1 to 1.5 million light years wide. Like Milky Way, countless galaxies are in the universe. By measuring their distance, we can learn about the true size of the universe.
Size of universe 93 billion light years wide
The universe is rapidly expanding. According to scientists’ research the most distant star from Earth is about 14 billion years old. That means its light took 14 billion years to reach Earth. Because the universe is rapidly expanding, that’s why today that the star is 46.5 light years away from us. On this basis, scientist guessing our universe has now been 93 billion light-years wide.

Harlow Shapley was an American astronomer. He used RR Lyrae stars to correctly estimate the size of the Milky Way Galaxy and the sun’s position within it by using parallax.
