Kreitsauce's Musings

As I said in a previous post, I’ve been reading a fascinating book by Hugh Ross entitled Why the Universe is the Way it Is. Dr. Ross has a Ph.D. from the University of Toronto and is the president of Reason to Believe ministries. He’s spoken at over 300 colleges and universities. While Ross’ book is by no means exhaustive, it does an excellent job of helping the reader realize how very, very, VERY unlikely it is for us to exist without a Creator. A disclaimer: Ross does seem to believe in some form of theistic evolution, at least to the extent that God allowed the universe to evolve and then stepped in to make humans several billion years later. I prefer to believe that God either created the entire universe with the appearance of age (since He did so with Adam and the rest of life on earth) or that- thanks to general relativity- God’s act of creation actually did some really cool things to the flow of time. I tend to go with the second option, but I’m not going to explain the whole theory in detail at this time. I also see some value in studying whether or not light itself could be slowing down.

Below you’ll see a few reasons why the earth is not only uniquely designed to support life, but also to allow mankind to view the heavens. God wanted us to discover His universe.

• For starters, there’s the atmosphere. It’s clear. If you read up on the atmospheres of other planets, you’ll notice that very few of them have clear atmospheres. If it weren’t clear but still breathable, we’d have no idea what space looked like.
• Then there’s the moon.Where else in the solar system can you witness a complete solar eclipse? Where else can the sun’s corona become viewable to scientists thanks to a perfectly round moon that regularly eclipses the sun? Earth is the only place this is possible because the distance between earth, moon, and sun, as well as the size and shape of all three bodies, is exactly right!
• In spite of how bright it appears, the moon actually only reflects 7% of the light the sun’s light. By comparison, the earth reflects 39%, Jupiter and Saturn’s moons reflect 60-90%, and Neptune reflects 73%. If the moon reflected more light than it did, we would have a hard time seeing much of the universe for most of the year!
• In a similar vein, the other planets are just so positioned that they don’t hinder our view of the night sky. Mars only comes close to earth once every 26 months and reflects only 15% of its light. Venus reflects 65% of its light, but because it lies between the earth and sun, we see very little of its light. If Mars and Venus were switched, Venus would be ten times brighter all night long, and we’d have a hard time seeing anything near its position in the sky. Switch Mars with Jupiter, and viewing distant galaxies would be impossible.
• The dust cloud from the galactic spiral arms that- as  I mentioned in the previous post- shield our solar system from lethal levels of radiation also block out much of the light from the rest of the galaxy. Other galaxies are made visible to us.
• Nebulae in our galaxy are relatively dark and very far from us. Things could have been very different. The Orion Nebula (located in Orion’s sword) is the closest “star nursery” to earth, and it blocks out a patch of sky the diameter of two moons. If, however, the Orion Nebula were switched, say, with the Tarantula Nebula, a full quarter of the night sky would be blocked out, and the nebula would be bright enough to cast shadows! We’d have a hard time seeing much in that case!
• Our galactic cluster is small and spread out, ensuring our ability to see many light years beyond our own galaxy.

As I hope you’re beginning to see, God not only cared about our ability to survive on our home planet, but He also wanted us to be able to witness creation. Of course, if you don’t believe that God made it all, all you’re left to say is: “What a wonder that we dwell in a galaxy in which we can see all its wonders!” But who believes in us getting this lucky?
