How Many Galaxies Are There in the Universe? – How many galaxies are there in the universe? Well, that is a very interesting question, isn’t it? Yes, the universe is obviously large and there are a lot of going on inside the universe. To discover how many galaxies exist there in the universe is a tough job.
As we know, the Milky Way or the galaxy that our solar system is in is only a tiny part of the whole universe. Surely, advanced science and equipments will be needed to determine how many galaxies are there in the universe. However, below is some estimation that you can consider.
The Estimation of the Number of Galaxies in the Universe
Countless astronomers have been working from time to time to determine the number of galaxies in the whole universe. They used advanced science to predicts the number. The estimation that we have today is approximately one hundred billion galaxies. It is just an estimations and a lot of astronomers think that the number could be even bigger than that.
The method used by the astronomers to make prediction or estimation about the number of galaxy is usually by taking sample of a particular region of the universe then counting the galaxies in that particular region. After that, they used advanced science to multiply the number of the galaxy in the particular region so that it meets the estimations of the number of galaxies for the whole, entire, universe.
Can the Number Improve?
Certainly. The estimation of one hundred billion galaxies in the universe is not a final number. It is believed that galaxies will always change over time. They move, they collide, and they merge to each other, and so on. That is why the number of the galaxies in the universe can easily improve.
If a group of stars and planets starting to collect together and they are all held by the gravity, a new galaxy will be born. It is believed that new galaxy emerges almost every day, making the number of one hundred billion is not permanent.
Those are the things that you need to know about the number of galaxies in the whole universe. Knowing that there are over one hundred billion galaxies in the entire universe, you should know better now that there will be many interesting out there, beyond the earth, to explore. At least by knowing how many galaxies are there in the universe, you can estimate how big the universe is.
