To quote Isaac Asimov: “The most exciting phrase to hear in science, the one that heralds new discoveries, is not ‘Eureka!’ but ‘That’s funny…'” This is another “That’s funny…” moment, and I’m very curious to hear what the cause turns out to be. Along with some other recent and curious discoveries, it suggests that the universe isn’t quite as ordered and predictable as we’ve thought.
Neat! A that’s funny moment led to the discovery of the microwave background radiation (big bang evidence) that accident gave Arno Penzias a Nobel Prize.
