The Universe in 101 words: Is it all a hologram?

Do physicists watch the Matrix too much? That‘s the first thing I think when I hear theories about the Universe being a huge 'hologram'. 

And, knowing my fellow physicists... yes. Yes they do.

But give them a chance: What they mean is that holograms are 2D surfaces containing 3D information, and our Universe might be 2D with the data for our third dimension stored on it. If that's so we’re part of the 3D information trapped on its surface... So how could we know? 

Well University of Southampton physicists may have found the signatures of a hologram in the cosmic microwave background...
