:Gravity itself won't compress (and 'flatten') the cores. "Shell theory" shows that gravitational force only counts from the proportion of the body that is within the radius of the bit you're concerned with. But there'll also be the external pressure (from being at the bottom of a thick atmosphere that ultimately ''is'' above far more of the planetary mass) and possibly a degree of compression density to make any Earth-sized core slightly heavier than if it was just a bare core of the same size but shorn of outer layers. | :Gravity itself won't compress (and 'flatten') the cores.

:As to flatness, I can take you to very flat stretches of Earth and very lumpy bits (depends which direction I go, from where I am now), all within 30 minutes' drive. We can'teven know how representative a sample of planetary cross-sections we are seeing (once we get over the issues of gas/space boundaries for gas-giants), but I bet there are bits that resemble the diagram... If you ''really'' want it to be so real.

There are several pieces of information here that are featured but don't make sense to me. What's the function of the dark polygon in the center? Why are the lines showing each surface going in random directions? Why is the surface of each planet so flat at a full scale rendition? When I look out my window at full sized Earth, it's not flat. It's quite bumpy, actually. But perhaps he doesn't mean these are full size, he might be saying that they're all shrunk, but the same amount, so 1:1:1:1:1... but even then, I'm totally lost. | There are several pieces of information here that are featured but don't make sense to me.
