Imagine the Universe! Ten Year Anniversary

Before 1999, astronomers had estimated that the age of the universe was between 7 and 20 billion years. But with advances in technology and the development of new techniques we now know the age of the universe is 13.7 billion years, with an uncertainty of only 200 million years. How did this come to be?

It's amazing. Another thing that amazes me is studies on plate tectonics and how by examination of types of rocks and fossils, and knowledge of the plates they can map where the continents used to be.

Not only that, but the older the rocks, the more simple and primitive the fossils. It's "right there". Evolution. We can pick evidence up right off the ground.
