Gravity as the breakdown of conformal invariance
... In summary cosmology appears to love the assumption that the universe starts 2-dimensional, with gravity switched off, or with all matter conformally coupled to gravity (just as happens with standard radiation subject to Einstein gravity). Then, the correct kind of fluctuations can be produced witho ...

... 3. Least Complex Level: Content target: Identify when a flat surface (2-D) is separated into equal parts. Example: Use a simple shape that is easy to identify for sameness when divided. Use only one type of shape per set of examples and no other changes in attributes across shape (color, size, ...
