And there you go... there's the answer to everything. A black hole on one side and, on the other side (the side we don't know), there's a whole new universe being sprung up. Each input goes to the output of a different black/white hole combo.

So basically, we're in a cable?

How many universes can we daisy chain together?

I'm having some trouble understanding this sentence: " [...] our 3-D ‘reality’ (plus time) is contained in a 2-D surface on its boundaries." What, exactly, do they mean with 'on its boundries'?

This is a statement of the holographic principle, which is that a projection on the surface (boundary) of a volume completely encodes the contents of that volume. You then no longer need the volume at all, you can perform all operations on the surface projection instead.

It's an awkward sentence. The 2-dimensional surface is the boundary of the 3-dimensional surface. I think what they're saying is that they believe the 3-dimensional universe is a 'reverse-projection' from the 2-dimensional surface.

It's interesting that to a layman this seems like almost the exact opposite of what string theory proposes dimensionally. Holographic universe theory is stating there are effectively less dimensions, while string theory shows there could be significantly more.

I'm not sure you're a 'layman' if you understand string theory.

This is the first time I've read anything about Holographic universe theory and I really don't understand anything about it yet. But, does this mean we were the ones living in a 2-dimensional "flatland" the whole time?

Actually, the big bang bears a pretty striking resemblance to a white hole. That's the time-reversed version of a black hole. Whereas with a black hole, all paths lead toward the singularity at its core, with a white hole, all paths lead away from the singularity.

And there you go... there's the answer to everything. A black hole on one side and, on the other side (the side we don't know), there's a whole new universe being sprung up. Each input goes to the output of a different black/white hole combo.

Tempting, but there's no evidence to support that.

I'm more worried about when the universe decides to start dropping ports and making everything wireless. :-P

Right... that's why it's a theory. A humorous, non-serious theory, but a theory nonetheless. (Replace with hypothesis if you want to get really pedantic about it)

I'm familiar with the idea of coordinate transforms and projections, so I get the idea that you could project our 3D universe onto a 2D surface, and I kind of see how a hologram encodes 3D information, but I don't see how that is a useful idea. Or are there only certain kinds of 4D information that can be encoded in the 2D surface, so our 4D model of space and time gets reduced to a theory of only 2 dimensions? Are there conceivable arrangements of a 4D universe that can't be represented in this way?

What does this mean? The universe is fake? Is this along the same lines as "everything is a simulation"?

Holographic means that the universe appears 3d but is actually 2d.

'appears' means that for us it is three dimensional.

'actually' means that the amount of stuff universe can hold is limited by 2d surface area, not 3d volume. Information/matter contained in universe is in '2d container surface' while interactions between them seem to happen in 3d universe.

In other words, the information/matter you can keep in volume of space is limited by it's surface area and not it's volume. If you try to add more, it becomes black hole.
