It always amuses me when scientists discover how little they really know about the world we live in. It always interests me as to how much more we have to learn and how it impacts our own learning and what we teach. |

Has anyone read the article?
The diamond is 4.5 billion years old, when scientists only expected diamonds to be 500 million years old at the most.
Would I like a 4.55 billion diamond?
Yes! |
