I didn’t misspeak. Black holes help us know the position/orientation of Earth.
“They … reveal jerks in Earth's rotation speed and wobbles in its axis that arise from earthquakes and hurricanes. …used in turn to correct GPS devices, which would otherwise lose track of Earth's spinning surface.”

We use distant black holes to know the position of Earth in space. If we invented GPS and didn’t use them to confirm our position, GPS would be inaccurate and unusable because we could not tell the precise positioning of Earth even though we’d know the relationship between your car and a satellite.

Ah! But GPS wouldn’t work without black holes so they very much do affect our daily lives

And now I have emails from legitimate humans who want to book meetings with me who are using LLMs to send me verbose emails that paraphrase my writing back to me.
Wish there was a polite way to tell them that they should stop and just write me an imperfect email that doesn’t read like spam.
