Originally proposed in 1899 by German physicist Max Planck, Planck units “…are also known as natural units because the origin of their definition comes only from properties of nature and not from any human construct.” (Wikipedia 5 Nov. 2016) The Planck length is 0.000000000000000000000000000000000016 meters: supposedly the shortest length possible in the universe.
How small is small? How big is big? How long is the shortest Planck?
There is a planck so short that anything shorter can't be measured, not now or ever, no matter how small your ruler or big your budget. The length of that planck is 0.000000000000000000000000000000000016 meters: supposedly the shortest length possible in the universe.
According to Wikipedia (5 Nov. 2016) “It is impossible to determine the difference between two locations less than one Planck length apart”. At that scale, Reality is discreet, i. e. lumpy, as opposed to continuous, i. e. without any breaks.
How quick are the breaks that Reality takes? As long as the Planck-time: a duration so short you can’t measure it, not now or ever, no matter how quick your clock.
There are many plancks in the ramshackle shack that we know as the universe. There’s a Planck mass, Planck area, Planck energy, even a Planck particle. How many plancks are there? Too many for Einstein: he wanted less wood, more marble.
Originally proposed in 1899 by German physicist Max Planck, Planck units “…are also known as natural units because the origin of their definition comes only from properties of nature and not from any human construct.” (Wikipedia 5 Nov. 2016)
Planck units are based on the Planck constant, “…a physical quantity that is generally believed to be both universal in nature and having a constant value in time” (Wikipedia 5 Nov. 2016): in other words, a number that applies everywhere, always, and never changes.
But what if they’re wrong?
