An astronomer discovers a new galaxy using a telescope. The astronomer wants to investigate how the galaxy is moving relative to the Milky Way galaxy.

In one or two sentences, make a hypothesis about the movement of the galaxy and explain at least one way to test the hypothesis.

Sagot :

No matter what, if you’re in an already existing galaxy, any galaxy outside of your existing territory will be moving away from yours.

The hypothesis about the movement of the galaxy is that;

Galaxies move far from each other continuously

      The milky way galaxy is the galaxy system that has over hundred billion stars and it also includes the solar system. It is also referred to as galaxy and the milky was is described like that because that is its' appearance when viewed from the earth.

       Now, since the astronomer has discovered a new galaxy, it means that the universe is continuously expanding. This is because the universe encompasses everything that exists.

        Now, galaxies move in space and since the universe space is continuously expanding, it means that the galaxies move from each other continuously. This means the farther the galaxy is from the earth or milky way which is an observable part of the universe, the faster will be the movement of the galaxy and the nearer the galaxy is to the milky way, the lesser will be the movement of the galaxy.
