Cameron :
we define it by 1 Mississippi ofc

DanaPhysics :
Regarding measuring it precisely anywhere in the universe is not true. Around massive objects it'll tick slower.

Stephen :
So our second is based on the length of a second in the 1950's and standardized by the Cesium?

does a second imply the existence of a first?

Didn't the metric system get a complete overhaul in recent years? So the kg is no longer defined by a block of metal in Paris?

The only issue that I see with this is high gravitational Force will cause the electrons to jump at an alternate rate

The problem isn't the second, it's the month.

theMostDangerousAnimal :
Well, we look at the first and then we define a second based on the first 🙄

Tom :
isn't wavelength defined in metres, which are defined as the distance travelled by light in a specific fraction of 1 second - defeating the point?

Why only Caesium atom though?

Michael is no :
define a second using a resistor and a capacitor

Will Strontium clocks replace Cesium clocks in near term future?

A pendulum Length one meter has a period of 2 seconds so half a period is 1 seconds

Every GPS satellite has 4 cesium clocks on board.

and how do we know that is consistent

"FREQUENCY" frequency is defined by second

how does the change in measure of a second change our m/s measurements. shouldn't it vary now proportionally to the change¿

Does this change with gravity?

looooongname :
its kinda like chicken and egg. to define the exact amount of vibrations of cesium atom in a sec, you would first need to know how long a second is.

why was caesium chosen?
