Aha, gravity!

What makes everyone and everything pull together? We feel it in our muscles when lifting something, but we don’t really notice it in our daily lives. Why does an apple thrown into the air sooner or later fall down, towards the centre of the Earth? Or why does a space rocket need so much power and force to break itself free from Earth?
