200-600 octillion microbes live a mile underground and thrive in 250°F water. Some breathe rocks, specifically uranium. Others eat leftover plants that are hundreds of millions of years old. And they can wait to reproduce for thousands of years when conditions are favorable. Add up all these wild subterranean microbes and they weigh as much as 200 million blue whales, much more than all 7.5 billion humans. And you know what? They’re related to us far less immutable surface dwellers. Bats hear shapes. Songbirds see UV light. Most animals are bioluminescent (including us!) but our eyes are too weak to see it without visual aids. Wonder is everywhere, a gift for all of us. Stay curious, friends. We have so many discoveries to look forward to.
