Apparently, there is enough uncertainty in measuring the diameter of a proton , about a factor of five. Maybe we shouldn’t ooh and ahh so much. Especially when scientists, for whom I have great respect, weaponize their prestige to influence public perception and debate in untestable and even unknowable areas.

All scientific knowledge is nothing BUT defining statistical measurement thresholds.

In this case however, it seems that they’re addressing the issue of even HAVING a statistical measurement threshold, not refining it.

So I guess that counts as a discovery!

I would reply to this thread but the act of doing so would alter what I was going to say

"Testing these relations, we are now able to show in the lab that we can actually reach this ultimate limit of accuracy," he said.

OK, but how certain are they of their findings ??

Article speaks of “incompatible” quantities whereas Heisenberg spoke of conjugate quantities ( like position and momentum). ——?
