My all-time favorite wikipedia article, great to see it getting some attention. I find that along with providing great fodder for small-talk (among certain types), it causes me to experience a psychological effect analogous to the so-called "overview effect" experienced by astronauts. Attempting to conceive of one's place in cosmological time is great exercise.

#mefour. I have recommended this article in various conversations over the years. I love how it's grown to include projections from various diverse fields. I feel I have lived forever after reading through it. And the mind-numbing scale eases fears over death for me.

Earlier quoted context omitted.

I would just change the duration of a second. It would be probably easier to change a few physics constants here and there than to fix all the broken code.

If only you were manipulating second only. You would also be manipulating metre, candela, and ampere, assuming old definition of SI , or metre, kilogram and kelvin assuming new definition of SI .

Can you explain how the duration of a second affects the metre?

One of my favorite Wikipedia pages of all time. A little sad that there are only three Biology events there though: North American earthworms spreading to Canada, coral reefs recovering, and C4 photosynthesis no longer possible. Can anyone think of more possible biology events?

We have added a second language of relication, language itself, to biology, and are using it to alter the first language in a rapidly expanding way.

It’s not easy to make predictions, short or long term, given this. The coral prediction, which does have the word “if” in it, also assumes we

Not OP, but "The metre is defined as the length of the path travelled by light in a vacuum in 1/299 792 458 second" - https://en.m.wikipedia.org/wiki/Metre

I still remember the first time I found this page, and the deep existential crisis that followed!

> The length of the day used for astronomical timekeeping reaches about 86,401 SI seconds. Under the present-day timekeeping system, either a leap second would need to be added to the clock every single day, or else by then, in order to compensate, the length of the day would have had to have been officially lengthened by one SI second. Can you just imagine the amount of legacy code with DAY_SECONDS=86400 out there 5…

They're missing a bunch of possibilities. Maybe a second is lengthened? Maybe we decouple timekeeping from the rotation of the Earth? Maybe we spin the Earth back up?
