Planck's law … fails … - SlideRule - 10-28-2019 11:48 AM

Excerpts from A Fundamental Physics Law Just Failed a Test Using Nanoscale Objects, MIKE MCRAE, 5 SEP 2018

"Planck's law of radiative heat transfer has held up well under a century of intense testing, but a new analysis has found it fails on the smallest of scales.

Exactly what this means isn't all that clear yet, but where laws fail, new discoveries can follow. Such a find wouldn't just affect physics on an atomic scale – it could impact everything from climate models to our understanding of planetary formation.

The foundational law of quantum physics was recently put to the test by researchers …

Not only does the law fail, the experimental result is 100 times greater than the predicted figure …

It's important to experimentally measure something, but also important to actually understand what is going on.

This hyper-efficient rate of energy transfer could feasibly change how we understand heat transfer in the atmosphere, or in a cooling body the size of a planet. The extent of this difference is still a mystery, but one with some potentially profound implications .…

This research was published in Nature."

Any Theory referred to as a Law (Newton's Law of Gravity et al) will eventually get its comeuppance Smile
