This idea was first but forward by one of the best Theoretical Physicists alive today – Gerard ’t Hooft. One of the great things about this man (aside from the plethora of academic credentials) is that he has created a website which brings together resources which are designed to help people who want to pursue Physics as a challenge. This website can be found here and I cannot recommend it enough.
The core principle at the heart of this theory is that a 2D surface can contain all of the necessary information to project a three dimensional world. The idea is simply that all of the laws and phenomena we have come to accept as common place in our world today are encoded on a thin brane which projects a three dimensional “reality” to us.
The idea was actually first banded about in the 70s, but until string theory made some significant progression the idea seemed nothing but sci-fi. With the increased understanding of string theory the idea has become more and more viable as a picture of the world we live in.
These spooky flat spaces first arose in what is known as curved anti-de-sitter space; a scientific construct which allows scientists to consider quantum theory in a 2D setting incorporating gravity in a 3D setting (if you know anything about quantum theory, you probably know of the long and turbulent relationship it has had with gravity). In fact it turns out a lot of things that didn’t previously make sense actually start to look a whole more realistic when you flatten out the universe.
Whilst the progression is very exciting and truly gives soome food for thought, there are a number of known truths that don’t quite marry in with the theory yet: one of the most notable being quantum entanglement. What do you think? Is this a step to far or a step in the right direction?
