A striking 
						example of so-called 
						
						settled science
						which was settled 
						prematurely is the question of how the moon got its 
						craters. 
						 
						
						As we entered 
						the Space Age, the debate among geologists and 
						astronomers only considered two hypotheses:
						
							
						
						
						After 
						
						Apollo 
						astronauts returned lunar samples to Earth, analysis 
						revealed a tremendous portion of the material was 
						composed of 'shocked and welded minerals.'
						
						Thus, the impact origin of lunar craters became the 
						consensus scientific theory, and remains so today.
						
						 
						
						Of course, 
						like so much 'settled science,' the dilemma was settled 
						without the successful resolution of countless 
						anomalies. 
						
						In this video, we explore the growing scientific 
						evidence that interplanetary lightning bolts carved the 
						lunar surface.
