I thought a second was exactly one Mississippi long

What if the cesium atom is speeding up?

but.... we could know... because it's specifically a fraction of the year 1900, not a fraction of every year.

A second has always been exactly one second long.

if the rotation of the earth is slowing even slightly then I think the laws of thermodynamics can explain climate change...

when he says "we", what has he invented aside talking too much? 😂

Making our concept of “time” a property of matter/light/energy & not of space, or its own “dimension” or “thing” in itself. Just an observational property of “things”. No spacetime, no flowing “river”

I’ve often wondered how we would be able to communicate with an intelligent alien race when our entire conceptions of time and counting, etc are based on no universal standards?

so our days are getting longer?

wouldn't that run into the same yardstick problem where you don't know any changes because the yardstick is changing.

This goes right along with my theory that the calendar is shifting. One year is 365.25 days right? You’re telling me it’s EXACTLY that? Or is it off that slightly so we feel like it’s getting colder

It’s still relative because there is no certainty that the transition of a cesium atom is constant. The time frame in which it exists may be changing.

so how will we know if atomic transition speed changes

does gravity affect the vibration of cesium atoms?

well, now we won't know if atomic vibrations changes over time.

Let’s all slow down and just think about this and never understand time🧠

Why does the Georgia guidestones have a hole that you can see Polaris everyday.

How do we know if this Earth slowing down or Cesium at Homs maybe speeding up?

weird, u mean the earth is getting old?

If gravity changes, doesn’t that change time?
