hi doma,
i believe it was actually the other way around. the holographic universe idea is derived from scientific hypothesis. i've linked to the holographic principle on a few occasions. here it is again.
http://en.wikipedia.org/wiki/Holographic_principle
"The holographic principle is a property of quantum gravity and string theories which states that the description of a volume of space can be thought of as encoded on a boundary to the region—preferably a light-like boundary like a gravitational horizon. First proposed by Gerard 't Hooft, it was given a precise string-theory interpretation by Leonard Susskind[1] who combined his ideas with previous ones of 't Hooft and Charles Thorn.[1][2] As pointed out by Raphael Bousso,[3] Thorn observed in 1978 that string theory admits a lower dimensional description in which gravity emerges from it in what would now be called a holographic way."
