“ A huge sinkhole in Guatemala City, Guatemala, crashed into being on Sunday, reportedly swallowing a three-story building and echoing a similar 2007 sinkhole also in Guatemala. The sinkhole has likely been weeks or even years in the making - floodwaters from tropical storm Agatha caused the sinkhole to finally collapse, scientists say. The sinkhole appears to be about 60 feet (18 meters) wide and about 30 stories deep. ”

Scientists measure Earth's history
“ I do think a lot about how inconsequential humans are in the big scheme of things. We have not yet even proved we're a viable species compared to dinosaurs, for example. Dinosaurs were around from 230 million years ago to 66 million years ago. That's a long time. They were very successful. Humans have been around for maybe a million years. It doesn't look like we're going to have that long of a legacy but we'll see.”

I have been thinking and saying that for years but this is the first time I see it written by somebody else, by a MIT's professor of Geology not some other opinionated dude like me. I also always use dinosaurs as a comparison..
“ EARTHTIME is an organized, community-based international scientific initiative aimed at sequencing Earth history through the integration of high-precision geochronology and quantitative chronostratigraphy. Our main goal is the development of the geochronological techniques necessary to produce temporal constraints with uncertainties approaching 0.1 percent of the radioisotopic ages.”
