Interesting article. GPS time even incorporates leap seconds to account for the Earth’s slowing rotation.

Not all seconds are the same!
One second of kissing a girl for the first time is not the same as one second of placing your hand on a stove burner on high!

Why do we drive on a parkway and park on a driveway?

Why 31 days in some months, 30 in others, and 28 in one ... unless there are 29?
It is NOT a funcion of the lunar cycle. Some months have two full moons.
Why not 10 36-day months with one 5-day “slack week” which stands on its own?

I want to know why the ocean hugs the shore.Good question. I don't know why but that fact makes the beach really nice. It's convenient having the shore and the ocean at the same place.

Does this mean a second measured by atomic cycling in radioactive elements will be the same on any planet, in any galaxy, since it is no longer tied to Earth’s rotation?
Would anything impact the atomic measurement?

They used to be a couple and are still friends. If you go to a point where two oceans come together you will see a group hug.

I don't know this but I'm guessing early christianity dumped the true lunar calandar, and because 12 months doesn't fit neatly into the year like 13 months of exactly 4 weeks each (plus a day or two extra), they had to add a few days to each month. Why the differences for each, I don't know either. To me, all the months being exactly 4 weeks each would be much neater. The 14th of every month would land on the same day all year long. The math would be much cleaner too. Superstitions i guess. heh ¯\_(ツ)_/¯

It is the amount of time it takes for a pendulum that is exactly one meter long to travel from one end to the other.

I even believe GPS factors in general relativity to compensate for time dilation.

Interesting article.
Some functions of time are based on natural cycles that can be measured here on earth. These would include a year, a season, a lunar month, and a day.
Other functions of time are human constructs. These include calendar months, weeks, hours, minutes and seconds.
What they're describing in this article is an attempt to convert seconds from a human construct to a period based on a natural cycle. This is a similar process that we've seen with metric measures that have been standardized over time.

Why 31 days in some months, 30 in others, and 28 in one ... unless there are 29? It is NOT a funcion of the lunar cycle. Some months have two full moons. Why not 10 36-day months with one 5-day slack week which stands on its own?
It is because the calendars would be wrong if it were any other way.

Actually it’s based on what a New York second is.
