Topic: Density Holes
I fell of the anti-rense wagon and decided to take a gander. Looking, of course, for stuff that's actually interesting instead of the normal sky is falling banter. I was greeted with a surprise. They call them Density Holes. We could all use one of those to crawl through right about now.
"The newfound bubbles are technically called density holes. In them, gas density is 10 times lower. The gas in the bubbles is 18,000,000 Fahrenheit (10,000,000 Celsius) instead of the 180,000 degrees Fahrenheit of the surrounding hot gas, which is known as plasma."
