      There is gravity everywhere! Gravity acts on anything that has mass, and the more massive something is the more gravity it has. This is why the planets go round the sun, because we are attracted to the sun’s gravity. It is also why we live in a galaxy because all the stars are pulled towards each other under gravity and form a galaxy!

      We can go to even bigger scales… because galaxies have gravity, they attract other galaxies!! We are actually being pulled towards our nearest galaxy neighbour, Andromeda!
      And then you get galaxy clusters, where lots of galaxies are pulled towards each other, and then super clusters and so on!!

      So everything has gravity and everything in the Universe is moving under the gravitational pull of something else.
