For a hundred years, Uncertainty has been a cornerstone of quantum mechanics, preventing the measurement of two factors at once. Werner Heisenberg, who first proposed the Principle, needed to explain that the position and momentum of a quantum object (such as an electron) could not be determined simultaneously. If you are measuring one, you cannot concurrently measure the other.
Now, Uncertainty has had an extension built, and the doors are open for further interpretation. Truly, after so many decades of fierce opposition to any extrapolation of the U.P., scientists have come round to the idea that the matter of inescapable fuzziness in the quantum world may well hold keys to other mysteries in Nature. Should you look up 'Expanded Uncertainty' on your search engine, you'll find a lot of maths and very little else, so rather than send you to links that are full of numbers, I'd like to invite you to join an expedition into unchartered territory.
We know that Nature doesn't like straight lines, or symmetry, or identical versions of things. Nature likes uniqueness, asymmetry, and fractal patterns. All natural objects, including snowflakes and sand grains, are unique. That's not to say that randomly across the desert there wouldn't be one or two granules that match, but if you were to look closely at their atomic structure, you would most likely find a difference in there somewhere.
This video explores the ramifications of the Uncertainty Principle and its extensions, wherein your own world may benefit from the opportunities it represents.
