About The Universe 2: Our Neighbourhood: The Earth and The Nature of Planets

October 18, 2006 Leave a comment

When I was a kid, I had a Time Life book called The Universe. It was published in 1967, two years before man first set foot on the moon. The Universe went into great detail about the neighbouring planets in our Solar System, but hardly talked at all about what lay outside. Without the internet or the money to buy books to find out more, I wondered about what is out there beyond the Solar System for many years. If you’ve been wondering too, then I’m going to tell you soon enough!

But first, let’s start at home with our own planet: Earth. In this chapter, I’m not going to try and explain the ‘how’ or ‘why’ of Earth, just the ‘what’; I’ll explain the overall behaviour of the Earth without explaining why it came to be this way. We’ll go into that later. Read more…

Some years ago, I had a young American girlfriend. One day, she told me she “didn’t believe in evolution” (evolution is the process by which plants and animals evolve over thousands or millions of years into more complicated or refined species). She said it as if evolution was something you could choose to believe in or not – like Santa Claus.

I was quite startled by this – it made me wonder what kids are being tought in schools in the U.S. these days – but, I should not have been so surprised. Nobody had ever bothered to explain evolution to her and she had no reason to ask: as a Christian with strong faith, for her, God created the Earth and put plants, animals and humans on it.

I am still friends with my ex-girlfriend and recently I approached her with renewed enthusiasm to try and give her meaningful answers about evolution and the general nature of physics and the universe, partly inspired by reading some books and other scientific material including an overdue re-read of Stephen Hawking’s A Brief History of Time. Brief History is meant to be a no-nonsense guide to modern physics for the layman, but in my personal opinion is still far too complicated for the person with no science background to understand. So I decided it would be interesting to publish a mini-guide of my own. Read more…
