Geoscientists from Scotland’s University of St. Andrews say they have evidence that will disprove the “Snowball Earth” theory; the idea that 600 million years ago, the planet was completely encased in ice a kilometer thick. They say rocks in Scotland show that even during the coldest period, the ocean water wasn’t frozen, which means that some parts of the Earth always remained unfrozen. 
The scientists did agree however that “Hell” would freeze over once the Lions won the Super Bowl. (Although we are starting to get a small glimmer of hope!)
