Pixelated Universe

Do we live in a pixelated universe?

Max Planck theorized a minimum measure of length (the Planck length) of the universe.  This length is the shortest measure above 0 that can distinguish "things" in the universe.  As a consequence there is also a minimum of time, the Planck time, that can be  measured.  This would be the time that light in a vacuum would take to travel a Planck length.

If there is a minimum length, then we can think of the universe consisting of nothing but pixels of Plank length in size (A Plank pixel).  If the universe consists of pixels, then is it possible that it is a giant very very powerful computer simulation?  Could God be the master programmer? 

It gives pretty compelling evidence for deja vu.  If the master programmer stops the simulation, winds "time" back, changes something, then restarts.  If not every bit of the old programming data was deleted, then deja vu could be the remaining bits of the previous trip through....

Many more questions are raised....  Are we all sentient beings?  Or are only a few set individuals sentient, while the rest are programed responses?  If the sentient beings can't see it, is it rendered? 

The sentient ones would be very powerful, self morphing, self programming, constantly changing and evolving programs. 

Perception then becomes something to think about.  When we "see", we don't actually "see", we perceive something.  The same is true for our other senses.  So we don't actually "see" a tree, we perceive a tree.  Does it make it any less "real" that we perceive?
