Actually I do have to say that I'm quite interested in SSL, the super velocity and selection theory of light that is the topic of Geoff Stone's book "But Where is the Rainbow?"... I'm more than happy to see Albert Einstein be nudged a bit off his pedestal. Not disparaging his work. But not every idea of his deserves to go undisputed, especially 100 years out!
I have thought a lot about time in a cosmic sense from hearing statements which I consider ridiculous such as that past and present and future are all the same, but this video made me think of how time is actually measured and kept in sync on planet earth. I didn't realize how complicated it was! With it being synchronized between the rotation of the Earth and the atomic clocks that are used... So I learned that the rotation of the Earth is on average slowing, and that they have had to add leap seconds in most years to catch up, but that recently there was one year where the Earth instead sped up its rotation! So they didn't have to add any leap seconds and were considering whether they would have to remove one.
We have to have a lot of confidence in the integrity of the atomic clock based system in order to consider it to be more reliable than UT1. There is a mountain of assumptions underneath.
Very well done Geoffrey. Very thought provoking and interesting. Hope everyone finds their "Rainbow" in Life.
बहुत बढ़िया वीडियो, जियोफ्रे के साथ दूसरा भाग कब आ रहा है?
Amazing guest❤
I hope this conversation will be continued soon since the surface has barely been scratched on these interesting topics!

@@St37One it's an interesting topic for sure. I liked the idea have you seen the motion of a distant galaxy to keep track of time
This discussion will improve once it gets more views
