According to a recent calculation by a team of biologists and geologists, there are a more living cells on Earth — a million trillion trillion, or 10^30 in math notation, a 1 followed by 30 zeros — than there are stars in the universe or grains of sand on our planet.
Still, it boggled my mind that such a calculation could even be performed.
Could Earth harbor even more life?
How much life is too much?
The finding “allows us to more quantitatively ask questions about alternative trajectories life could have taken on Earth and how much life could be possible on our planet.”
