Visualizing the Planck Length. Why is it the Smallest Length in the Universe?

Just a short while ago, I shared a phenomenal science video that provided you all with some great insight relative to the smallest object in the Universe and progressed to the largest object in the Universe... Now I am going to take you on a Video trip with some great detail on the Smallest Object in the Universe... A little beyond Physics 101...and you must focus if you haven't been this far in negative numbers territory...

It starts out like this:

"The scale of the universe is bigger than you can imagine. It is also smaller than you can imagine. The smallest length theorized to be possible, the Planck length is about 4 X 10^-35 meters. Just imagine things that are about the size of your body. Things like the giant earthworm that lives along streams in Australia. Or a big beachball, which can be found near oceans and beaches all across America.

Now, lets go smaller by one order of magnitude, so now we are looking at things that are on the scale of about 10 centimeters. These are things like the shrew, or a chicken egg.

Now let’s go a thousand times smaller than the scale of a human being, on the order of 1 millimeter or one thousand of a meter. Here, you’ll find things like a grain of sand or dust mites.

Let’s go 1000 times smaller than this scale. Now we are going a hundred times smaller than the width of a human hair. And ten times smaller than even bacteria. Here, we are going to find things like large viruses." -Arvin Ash

And it goes on from there... It is fascinating and I hope you enjoy it!
