This Comet Stinks
I’m very disappointed.
The huge chunk of gas (called G2) that was supposed to be engulfed by the supermassive black hole at the center of our galaxy in a wonderful display of pyrotechnics never did and now they think they know why. It’s really a star.
The war against anti-science agents in the public school systems around the United States never ends. Battles are fought in perpetuity in all 50 states. Here is one battle in Arizona which involves the censorship of science thanks to the efforts of a few activists on the opposing side.
A mystery may have been solved as to why Animals didn’t flourish earlier in earth’s history even though oxygen levels should have permitted it. Scientists claim it’s because oxygen levels at that time were a fraction of what we thought they were.
Big multi-cellular life really proliferated on the earth in the period of geologic history called the Proterozoic about 800 million years ago. But the preceding billion years or so seemed to have enough oxygen for the simple organisms then existing to take advantage of. The bottom line question then has been: What the hell took so long?
