Stromatolites and Fundamental Forces

The video explores Earth's history, focusing on the evolution of life and recent fossil discoveries. It discusses the Late Heavy Bombardment and the possibility of life existing over 4 billion years ago. New findings in Greenland suggest life may have begun earlier than previously thought. The video also covers fundamental forces of nature and a potential new particle that could indicate a fifth force. SciShow's Patreon plans for a new show are also highlighted.
