Goodness! PINGING KOSTA50 THIS TIME, TOO.
What do I know. Just one of the massive number of threads I scan so frequently—98% on FR. I’m very sure it was on FR.
I don’t recall anything about the title.
I was just very struck by this rather longish lasting “truth” about light being proven wrong suddenly. I think it was a European experiment. But I think it was quickly verified in the USA. It was a very clever experimental design. I think it involved splitting a laser beam etc. etc.
It was on the outer limits of my easy understanding of such things so I didn’t dwell overlong on it. Sorry.
I think that’s the best I can do. But I’m certain the thread was on FR. And, I think in the last 3-6 weeks.
Thanks, Q. Much obliged.
