A well-intentioned friend of mine alerted me of the video link below. This is the first time I am hearing of this holographic universe term. The video claims that this so-called holographic universe "proves" that the physical world we believe is real is in fact illusion. Apparently there are five parts to this series; I didn't go beyond Part 1. I thought it was Neurology at its most rudimentary level!
Happy watching - if you have time!
