Hi Alea....
Actually the holographic universe idea goes back
over 10,000 years and is found in ancient Indian
texts....Susskind's hypothesis is that the
maximum information that can be held in any
volume of space is dependent on the sum of the 2D
surface area,and that is holographic by nature....
A hologram is a 3D representation of 2D information.
You may well believe that human civilisation is
at its peak in terms of scientific knowledge,i
believe we are just uncovering what the ancients
knew over 10,000 years back.....civilisation travels
in cycles of knowledge that is lost and then
re-discovered.
