I knew about redifining the kilogram as it's related to gravity beforehand
But not the next part about kg and photons and planck etc etc. I learned all that just now by reading a response to my comment
I genuinely did not know about the relationship to light until just now.
So, yes. But again, your comment alone didn't help me understand about the relationship beforehand. I wasn't sure what you meant at all, so just responded with my understanding of it
