Earth Barely Tall Enough to Ride Life Ride

Ok, so it was a bad joke. Apparently, the Earth is just barely big enough to support life. The National Geographic is reporting this new research that says the Earth is barely big enough for plate tectonics, which are critical to CO2 formation and maintenance, which in turn is critical for life. It’s an interesting finding, because it means that if we want to look for a place in outer space that could hold similar conditions as Earth, we need to be looking for much larger, rockier places. Maybe the Earth is a one in a gazillion place?
