Scientific Predictions and the Bible: Unknown Facts Revealed by God
If the Bible is inspired from the one true God then we would expect its statements about science to be compatible with the characteristics of that God as revealed in the Bible as discussed in the first part of this four part series on Scientific Predictions and the Bible. The scientific statements in the Bible should be accurate, culturally relevant, and instrumental in God's primary goal of redeeming individual people so that they can have a relationship with him. It is also reasonable to propose that scientific statements in the Bible may have a kind of dual understanding just as certain Messianic prophecies have a dual fulfillment as discussed in the second part of this four part series. In this third blog entry on the subject let's look at some cases in the Bible where there is an accurate scientific statement that was not known when the Bible was written but has since been verified.

A Small Big Universe
The universe is unfathomably large. Our galaxy, the Milky Way, is made of around 200,000,000,000 stars and there are about 200,000,000,000 galaxies in the visible universe. The Milky Way galaxy is about 100,000 light years across, which is 9.5 × 1017 km (6 × 1017 miles). (A light year is the distance light travels in a year which is 9,500,000,000,000 km or 6,000,000,000,000 miles.) We can see galaxies that are so far away it has taken about 13 billion years for their light to reach us. Since the universe is expanding, those galaxies have continued to recede away from us during the time it took their light to reach us. So the present size of the known universe is approximately 93,000,000,000 light years across in all directions. That is, the universe we can see is now a sphere about 9 × 1023 km (6 × 1023 miles) in diameter. We talk about the "visible" or "known" universe because that is all of the universe we can see. We have no idea how large the universe is beyond that.
It is impossible to understand how big this is. Consider something much smaller, the distance to the nearest star which is about 4.3 light years away. If we could travel to that star at about the same speed as the Apollo astronauts traveled to the moon, it would take almost 1 million years to get there. That is just to the closest star in our galaxy! Even if we could travel at the fastest speed of any object ever created by humans it would take about 30,000 years to reach the nearest star. You can do the math, but even at that extreme speed it would take 700,000,000 years to cross our galaxy.
