The Andromeda Galaxy collides with the Milky Way

Scientists and astronomers say that the next two galaxies, Andromeda and the Milky Way, will collide in the next 4billion years. At 2 million light-years away, the Andromeda galaxy is one of the closet galaxies to the Milky Way. The Milky Way galaxy is 100,000 light-years in diameter; The diameter of the Andromeda galaxy is 220,000 light-years. These two galaxies are large galaxies. The collision of two small galaxies creates one larger galaxy. The two galaxies, Andromeda and the Milky Way, are both large. Two large galaxies, such as Andromeda, collide with the Milky Way every 9billion years. Okay; Now the question is what happens to the Earth? It is estimated that in another 2billion years, the Sun at the center of the Solar System will turn into a red giant and destory the Earth. In this estimation, there are two answers that reach them the most: 1=> The Sun grows so big that it devours the Earth. 2=> The Sun grows so large that the Earth burns like a piece of wood and nothing remains on the Earth. However, scientist are wondering how the Earth can be saved. In future, scientists and astronomer with technology and science that is many times better than today; Maybe they can save the Earth. #The_Andromeda_Galaxy_collides_with_the_Milky_Way
