The latest newly discovered meteor impact that did not cause the Younger Dryas
There is little doubt among archaeologists that the Younger Dryas, a cold snap following the initial retreat of Ice Age conditions some 11,000 years ago, had a major impact on human history. It seems that humans are highly motivated to return the impact to the Younger Dryas. Two times in recent years, evidence of an impact, a celestial object whacking into the Earth, has been suggested as the cause of the famous climatic “two step.” As sexy as impacts are, however, it is very unlikely that the Younger Dryas was caused by one.

How many satellites are there, and will there be?
The number of satellite circling the Earth right now is approaching 5,000. The number that are not broken, and are being actually used, is just over 1,000. However, Space X, Elon Musk’s megacompany, is approved to launch well over 10,000 satellites over the next several years, to serve a single purpose: Give broadband internet to every human on Earth no matter where they are. Continue reading How many satellites are there, and will there be?
Is White Supremacy and Lynching People Racist?
Sen. Cindy Hyde-Smith got all titillated the other day when she thought about sitting in the front row of a public hanging. In the context of her race to be Senator of Mississippi. Which is the state in which the most recent well known lynchings took place, and that probably had more lynchings per capita than any other state. Her opponent, Mike Epsy, is a black man. Continue reading Is White Supremacy and Lynching People Racist?
