Although the universe is expanding and all galaxies move away from each other, this does not happen locally. Thus, the Andromeda Galaxy is approaching the Milky Way at a speed of almost 120 kilometers per second by reducing the distance of 2.5 million light years separating us. With this breakneck speed in about 3.75 billion years the galaxies will unite. When they collide, it is believed that the Sun and other stars will probably not collide with stars of Andromeda, but the two galaxies will form a single elliptical galaxy shape. The process of this compound is estimated to last 1 billion years, according to scientists in our solar system will not only survive, but the Earth will see a unique spectacle in the sky as the two galaxies will merge. Conflicts - Galaxies combinations of the enormous distances between them may be the only way to contact intelligent beings from different galaxies.
