Question Your World

People all over the world, regardless of race, age, location, or culture all have one thing they can always talk about, the weather. Our day to day world is always subject to changes in the weather. Sometimes weather produces violent storms, catastrophic gusts of winds, or sudden extreme changes. For example, recently the United States seems to have experienced an extreme bout of arctic cold.

Way back around the time of dinosaurs the first crocodiles started to appear. After millions of years of evolution they have become the intense hunters and frighteningly large reptiles that we know today. These animals are the alpha predators in some parts of the world, are stealthy hunters, some have the strength to bring down a small elephant, and they just got even scarier! One of the scariest questions in the world just got answered. That question? Can crocodiles climb trees?

As we move into the future with more powerful technology and a better understanding of the past we are starting to piece together the past as accurately as possible. Our origins have fascinated us for nearly all of recorded history and continue to do so today. With this better understanding we can finally start to answer some of the big questions about our existence on Earth as the dominant species. So, how did we become who we are?

Knowing something is a pretty relative concept. For a long time we knew that the Earth was the center of the universe, later we learned we were wrong about what we once knew. So, accuracy means a lot when we say we know things. Using technology, we've been able to accurately know a lot of things about our natural world. There are still many things big things left to learn about, such as the size of the known universe. How accurate are our measurements of the universe?
