Hi, just reading an article in the Irish Independent about OGLE (Optical Gravitional Lensing Experiment) Scientists who have discovered a potential earth-like planet (using the gravitional signature of the planet from the light emitted from it). This planet resides in the constellation Sagittarius and is 20,000 light years away. That if I am right would be roughly 200,000 trillion kilometers away. (Light moves at a velocity of about 300,000 kilometers (km) each second. So in one year, it can travel about 10 trillion km).
It got me thinking about distances and our tiny place in the scheme of things. The nearest big galaxy to ours is a stunning 21,000,000,000,000,000,000 kms away. Now this is were your head is going to get totally destoryed if you think too long on it, the Hubble telescope galaxy list contains 3000 galaxies. Its coverage so far is around an area of sky of only about 0.04 degrees on a side, meaning that we
would need 27,000,000 such patches to cover the whole sky. That means Hubble is probably capable of detecting 80 billion galaxies but that is only observable ones.
With an area of space so incredibly vast and that is only the small area we can barely observe, you really start to feel exceedingly tiny? With this in mind, our whole base of religion would seem slightly cocky? Do you think our religions would be destroyed if we discovered life elsewhere in space?
