It all started with me looking up at the sky one night and asking myself what I thought was a very simple question: “how does the Moon affect us and other animals on Earth?”. When I started asking this question around I got a lot of confusing and contradicting answers. So the first thing I thought I should do was to speak to an astronomer to find out what exactly the moon does to our planet. Prof. Tim O’Brien, associate director of the Jodrell Bank observatory, did an excellent job at explaining to me how and why tides our formed. I was actually quite embarrassed when I realised I knew so little about the science behind sea tides.
