Sounds pretty ridiculous...please don’t tell me people get paid for this nonsense.

[Do the math]

A projection is a mathematical operator. An simple example of a projection is the shadow of a football on the ground as it flies thru the air. The football is three dimensional, and its projection ( it's shadow) is only two dimensional. We do not know how many dimensions exist in our universe. I suspect that our universe is essentially an infinite dimensional vector space unlike the proponents of string theory who want it to be finite dimensional. However, since we live in 4d space-time we can only perceive the projection of the universe onto our observible 4d subset of the universe.
So what we perceive is more like a shadow than a hologram. Does this explanation help?
