You might think your fifty inch 1080p screen has a pretty high  
resolution, but reality is a quadrillion times better - a hundred  
trillion dots per inch.  A collaboration between Fermilab scientists  
and a hundreds of meters of laser may have found the very pixels of  
reality, grains of spacetime one tenth of a femtometer across.
The GEO600 system is armed with six hundred meters of laser tube,  
which sounds like enough to equip an entire Star War, but these  
lasers are for detection, not destruction. GEO600's length means it  
can measure changes of one part in six hundred million, accurate  
enough to detect even the tiniest ripples in space time -  assuming  
it isn't thrown off by somebody sneezing within a hundred meters or  
the wrong types of cloud overhead (seriously).  The problem with such  
an incredibly sensitive device is just that - it's incredibly sensitive.
The interferometer staff constantly battle against unwanted  
aberration, and were struggling against a particularly persistent  
signal when Fermilab Professor Craig Hogan suggested the problem  
wasn't with their equipment but with reality itself.  The quantum  
limit of reality, the Planck length, occurs at a far smaller length  
scale than their signal - but according to Hogan, this literal  
ultimate limit of tininess might be scaled up because we're all  
holograms.
Obviously.
