Would the number of galaxies change?
Change is the law of nature and our celestial space is way more prone to change that our observable world.
It is imperative to know that our universe is constantly evolving, two galaxies can collide into each other and form a new one after the complete destruction of the former two. This leads us to believe that the total number of galaxies could constantly be changing. While the current known number of galaxies is only a conjecture based on our current research, the number is susceptible to change.
Even our own galaxy has been evolving throughout the years and it is predicted that the milky way will collide with our closest galaxy in another 4.5 billion years.
How Many Galaxies are in the Universe?
Years ago when the great astronomer Galileo looked through his telescope into an ocean of stars, we were first introduced to our galaxy, The Milky Way. Since then the mere size of our universe has continued to baffle us.
Later in 1924, Edwin Hubble detected more fainter stars around nebulae. On further observation through this 100-inch telescope, he concluded that the seemingly fainter stars were too far away to be a part of our home galaxy. Further inspection into his curiosity led him to believe that we might not be the only galaxy in the universe.
Edwin Hubble created the Hubble telescope, which was a turning point in astronomy. The Hubble Telescope, located 525 km above the earth’s surface, helped us see into our galaxies’ past behaviour, formations, and destructions. It also helped assert that our universe is constantly expanding. Since this discovery, the universe’s expansion might also be slowing down significantly.
