Number of Planck volumes in the observable universe

This is the largest number that can be directly applied to observations of our 3 spatial dimensions.

On the scale of this number, ‘1’ corresponds to the Planck volume - the smallest space physically possible.

Each side of a Planck volume is called a Planck length, this is attributed to wavelengths, temperature & energy.

The reason for this is that if an object is heated, it radiates different wavelengths (sine waves that are core to observation) than it did beforehand, the differences created include:


 * Length. Each wave will take up less space, these short waves are used to observe small spaces.
 * Energy. Each wave will take up more energy, this interferes with observations.

At first the interference does not definitively limit how small an object can be observed but if a certain threshold based on \( e=mc^2 \) is met, the energy creates a kugelblitz (black hole).

Therefore, nothing can be observed smaller than a Planck length or volume.

The Planck volume (1) helps define a scale for the number at hand, allowing it to equate to the total Planck volumes that have emitted wavelengths to us.
