Assume an infinite number of brains. Is it still possible to figure out a way to break the Laws of Nature? Yes or no, please.

What laws of nature? Gravity?

Sure, why not.

Just please note, aeronautics does not defy gravity. It makes use of knowledge in mechanics of fluids to produce vouyancy, which ultimately is a manifestation of gravity.

To be more clear, infinite knowledge does not allow you achieve any arbitrary goal you care to imagine. It informs you on what means can be used to achieve the subset of goals that are feasible to begin with.

Throwing arbitrarily large amounts of computing power to the same problem may as well result in a flood of responses: "No. Nice idea, but it has been tried before N times, last time at T. It never worked because of X, Y, and Z"; "No. Nice idea, but it has been tried before N+1..."

Until extremely recently Africa has (with the exception of the Nile delta) been very under-populated. Even today it's regions do not rank amongst the most populated regions https://en.wikipedia.org/wiki/Population_density (with the exception of the Nile delta) Historically Africa had very little population growth compared to the tiny population that survived the "out-of-africa" exit. I would speculate: part of the re…

Scarcity of reliably arable land combined with extreme disease burdens probably have something to do with that.

It's actually much more simple. It's just urbanization vs rural. As urbanization increases, population density can increase. Until very recently Africa was mostly rural.
