RE: Defining time with atomic fountains
There's something I'd like to understand. Is UTC the same as GMT? While growing up, I heard majorly about GMT, but it seems UTC has overridden that.
An unrelated question: I read an article that stated that the earth's day is getting longer by few miliseconds every 100years. Does this have effect on the Gravitational time dilation?
PS:
hold on for a second. I know: I ate a clown today and here is the proof.
Huh? You ate a clown? :D
There is a slight difference, at the conceptual level: UTC is a time standard and GMT is a time zone. But the time itself is the same.
Every thousands of years actually. In principle, there is an impact, but you need to integrated over billions of years to notice it.
Thanks a lot for the quick lectures.
Always a pleasure my friend :)
