Planck Length facts
While investigating facts about Planck Length To Inches and Planck Length Time, I found out little known, but curios details like:
62 decimal digits of pi is all that is needed to calculate the circumference of the known universe to Planck length precision
how planck length is calculated?
Humans are closer to the size of the observable universe than they are to the smallest unit of measure (Planck length)
What is smaller than planck length?
In my opinion, it is useful to put together a list of the most interesting details from trusted sources that I've come across answering what happens below the planck length. Here are 16 of the best facts about Planck Length Comparison and Planck Length Explained I managed to collect.
what happens at planck length?
-
If the Planck length is the smallest possible thing, and the observable universe is the largest possible thing, then an object which would roughly sit in the middle of these two sizes would strangely be.... an adult human body.
-
Humans are, logarithmically, in the middle of size on a scale of planck length to the size of the universe.
-
It would take more Planck lengths to span a grain of sand than it would take grains of sand to span the observable universe.
-
One of the smallest known measurement is a Planck Length. It's so small, if you were to magnify a 0.1mm dot to the size of the universe, a Planck Length is a 0.1mm dot inside that universe-sized "dot".
-
The size of the human body is almost exactly halfway between the size of the known universe and that of 1 Planck length (smallest known spatial unit.)
-
Graham's number is so large, it couldn't fit in the universe even if every digit was a Planck length, the smallest measurement.
-
Quantum Foam measured at Planck length is comparable in size to a .1mm dot as that dot is to the entire observable universe
-
A Planck length is SMALL Imagine the smallest particle you could see with the naked eye (about 0.1mm across) expand to the size of the observable universe. At this scale, a Planck length... would be roughly the size of a particle 0.1mm across.
-
If you took a human hair and blew it up to the width of the observable universe, Planck length would be blown up to only 1/4000th of an inch
-
The number of planck lengths you could fit across a single brain cell, is equal to the amount of brain cells you could fit across the entire observable universe.
Why is planck length smallest possible?
You can easily fact check why can't anything be smaller than the planck length by examining the linked well-known sources.
On A Scale of the Smallest to Largest Measurable Distances, the Planck length & the Observable Universe, the Logarithmic mid point is a human brain cell. That is, a neuron is as many Planck lengths wide as the universe is neurons across. o_O
The Planck length has no particular physical significance - it's simply a ratio of fundamental constants that has units of length. - source
The Planck Length, the shortest measurable distance. In theory, no matter how much technology advances, it is physically impossible to measure a distance smaller than a Planck Length.
