I am going to take a quick time out from book writing here and make a post...
By boosting the power of the Keck II telescope atop Mauna Kea volcano, astronomers believe they have glimpsed light from some of the universe's first stars, seeing farther into space than ever before.
How far, you may ask? Scientists said they were able to see light generated by galaxies 13 billion years ago, when the universe was only 500 million years old. (The universe is 13.7 billion years old.)
Read the news article: Telescope gives deepest view of space
Did you know that looking through a telescope is a little bit like getting into a real-life time machine? When we look at space bodies, we are seeing what they looked like in the past. For example, when we look at the sun (which I don't recommend, by the way), we are seeing what the sun looked like 8 minutes ago. When we see Alpha Centari (our nearest star) which is located 4 light years away, we are seeing it as it appeared 4 years ago. Likewise, the Andromeda galaxy (our nearest galaxy) is 2 ½ million light years away.
So when this article says that astronomers are seeing stars that are 13 billion light years away, that means they are peering back in time at the universe as it appeared in its infancy.
We live in such a wonderful time. It truly does give new meaning to the words in Psalm 19, "The heavens declare the glory of God; the skies proclaim the work of his hands. Day after day they pour forth speech; night after night they display knowledge."
P.S. For me personally, understanding the concept of light travel caused me to abandon any remaining doubts I had about believing in an ancient universe. At that point, I didn't know all of the answers or how everything fit together, but I knew that believing in a universe that was only a few thousand years old was a direct denial of God's revelation through nature. God cannot lie. It's not in His nature. So why would we think that He has created the entire cosmos to display His glory, to proclaim His love, His eternal nature, and Divine righteousness, but have the whole thing premised on a lie - that the universe is old when it is, in fact, young? That just doesn't make any sense.
I reasoned that whatever the message of the cosmos is, it has to at least be plain enough so that unbelievers can interpret it correctly. Otherwise, Romans 1:18-20 cannot be true. How could unbelievers be held accountable for their denial of the Creator when the information about that God set up to proclaim the message about His existence is all premised on a lie? Unbelievers don't even have a fair chance to understand message in the first place, so how can they be responsible for their rejection of the Creator? See the problem here?
