Find out how many light years our universe has expanded

Washington, July 11, 2020, Saturday

The sky is considered to be infinite, it has no end. The universe is so large that it is difficult to estimate. However, according to the information received, after years of hard work, scientists have also measured the universe. The universe is estimated to be 3 billion light years wide. Light is the unit used to measure long distances in years. The speed of light is bright. It covers a distance of 3 lakh km per second. The light year is determined by the distance traveled by the light year in a single year.

Light years are considered to be the basis for such long distances as it is extremely difficult to show in miles or kms. Chappell believed that this galaxy was not so large. While Curtis calculated its distance to be 60,000 light years. However, this is very old.

It is now assumed that the Milky Way is 1.5 million light years wide. Given the vastness of the universe, the Earth is about the size of a drop of water in the Pacific Ocean. The universe is still constantly expanding. Two stars are measured by radio waves. Called the Cosmic Destroyed Ladder. Radio waves are sent to other planets and stars. The distance between the planets and stars is determined by the time it takes for these waves to come and go. This requires large telescopes. A similar telescope is installed in Puerto Rico. Its name is Arecibo.

However the universe is so large that radio waves fall small to measure it. At this point the brightness of the star and the speed of light help. The galaxy Adromeda is about two and a half million light-years from Earth. As something moves away from us, our eyes move away from it. Scientists call this process Redshift.

Because the light emanating from any star is lost around. There seems to be a difference in its color. In the same way, its distance can be measured by understanding the shining stars as milestones. However, this is not a strong basis for calculating distances, since it was discovered in 1905 that not all stars are the same. However many also believe that it is very difficult to say how big the universe is.
