bit of quibble, but a geological era, as a technical term, describes a duration on the order of 100MYA, which is nearly 1/100th of the age of the universe, making 'nanosecond' a bit of an exaggeration. even if we consider periods on the order of 10MYA (how long ago the titular lake disappeared), that's still on the order of 100000x a human lifespan, versus 1/1000th the age of the universe.
anyway, i bring this up mostly because, while it's widely appreciated that spatially speaking earth exists an a scale utterly insignificant compared to astronomical distances, from a temporal perspective the age of the earth (and the duration of life on earth) are actually quite comparable to that of the universe

- lostlogin 3y agoI might be misunderstanding, but could OP mean ‘age’ and you mean ‘portion of lifespan’?
- GranularRecipe 3y agoI don't think that "lifetime of the universe" is well-defined. The universe would still exist after the heat death.
