Big Picture Science - Deep Time
ENCORE: Think back, way back. Beyond last week or last year … to what was happening on Earth 100,000 years ago. Or 100 million years ago. It’s hard to fathom such enormous stretches of time, yet to understand the evolution of the cosmos – and our place in it – your mind needs to grasp the deep meaning of eons. Discover techniques for thinking in units of billions of years, and how the events that unfold over such intervals have left their mark on you.
Plus: the slow-churning processes that turned four-footed creatures into the largest marine animals that ever graced the planet and using a new telescope to travel in time to the birth of the galaxies.
