Dinosaurs were said to have slowly died after a pretty large asteroid hit the earth. It seems that a recent bit of work on the subject has determined that the asteroid may have been half the size than originally thought. A paltry 4-6 kilometers across…I don’t know about you, but that seems pretty damn big!!!
Another thing that appartently occurred during the Cretaceous era, was that there wasn’t a lot of cloud cover to protect the atmosphere, and reflect the sun’s energy. Temperatures rose dramatically, and it is suggested that it effected plant growth, and the whole food chain. The researchers are paticularly interested in the effects of green house gases, so we can try to fix our current global warming crisis.
On the other end of the spectrum was the year 1600. An eruption of a Peruvian volcano may have cooled the earth and created grave conditions for crops, with frost and famine killing plants, and may have created great social unrest.
Today seems to be a busy day on the science front!
When I was a kid, I would lie on the porch at night with my sister and stare up at the stars. We would try to wrap our heads around the vastness of the universe. That it went on forever. Or does it? The Big Bang theory is kind of hard to understand, but if you have ever asked “what happened before the Big Bang”, then here is a neat story. My only question about this article, is where do you come up with the math to recreate the Big Bang and before?
