What could be said about the Holographic universe theory by Craig Hogan, and similar proposals by L. Susskind?
Do these Theories really state, as some magazines suggest, that the universe is only 2 dimensional, or is that just a mathematical simplification to explain certain phenomena?

Can the universes have less then 3 dimensions?
Would gravity work in such an universe the same way as we know it?

What do you think?

Sure it is possible. A better question is whether or not it matters.

I haven't read about the Holographic universe to be perfectly honest, but other dimensions can be effectively represented in other ways so the laws of the universe don't change.

Using maps as an example, elevation is often indicated by colour on a 2D surface. So, equally, the universe could be represented as a colourful 2D sheet. Equally it could be represent as a coloured 1-dimensional line with a third "hypercolour" property that defines the third dimension.

The opposite of doing this is to assign a property of the universe that we can observe (such as the curvature of space due to gravity) to its own dimensional axis, which is essentially what is happening in all those "rubber sheet" demonstrations of gravity which you have probably seen - gravity is being represented as a 4-dimensional effect in an apparently 3-dimensional universe.

Going back to our universe of reduced dimensions - all physical laws would operate in the same way because these colour and hypercolour properties would presumably be representable on a continuous spectrum upon which (speaking mathematically) each shade could be assigned a number which could be translated onto a dimensional axis.

Following on from this analogy... just as reducing the (apparently) 3D universe to only 2 "real" dimensions could be a mathematical "simplification", it is perhaps possible from some perspective that it is actually a mathematical overcomplication to consider each of the 3 spatial dimensions as equivalent, and, in fact, each represents some unique property which we can (presumably) not perceive, and their apparent equivalence is just an illusion of our viewpoint (from, obviously, within this universe of ambiguous dimensions).

Not sure if that was the sort of answer you were looking for but hopefully you find it of some use in your understanding.

Any new Ideas on this?

The idea for the universe as a hologram sounds me quite strange.

The theory demonstrates the fabric of spaces potential, this is a dimension much as our material dimension holds potential. It's a shame that it has to be glamorised to get destract/entertain, Black holes anyone, get your blackholes here, buy one get 3 free, Universe sold separately. WARNING: Not all Universes are compatible!
