Selected silly reactions

1. Isn't that beautiful? Our Creator God not only created billions of stars that man hasn't even discovered yet, but He also "CALLS THEM ALL BY NAME"!!! -- on He Counts the Number of the Stars! This one is almost touchging in its ridiculousness. I never expeced this kind of reaction... not ever.
2. Maybe the scienntist will eventually peep into God's conference room and see the negotiating going on for the soul of the United States. -- Tony Campbell on The Slatest Commentary.
3. How narrow minded of these scientists to think they actually know a 'rough estimate' of how many stars exist, or how big the universe is. -- johnomazz on digg.com.
4. To lose one galaxy, Matthew Hayes, may be regarded as a misfortune, to lose 90% of the universe looks like carelessness. -- Arthur Scringeflockett, Newquay, Cornwall in The Daily Mail's Comments Section.
5. Actually you have it reversed, in the '60s Peebles and some other guy predicted there should be a large number of Lyman-alpha emitting primeval galaxies. For a long time no one saw the amount expected. But I guess this new paper shows that these primeval galaxies really are out there. -- Steven on Newmark's Door -- Things One Middle-Aged Economist Finds Interesting.
6. More Goddy Stuff.
