Yes I have read the things that he’s written. I also have a doctorate in physics and there is nothing in there that answers my questions. What Brown has done is cherry picked a few bits and pieces of physics and smashed them together in a way that doesn’t tell any coherent story and mixes together different ideas and experiments that are unrelated to each other. Take for example his ‘logical conclusions:’
Logical Conclusions
Because Earth’s radioactivity is concentrated in the crust, three corollaries (or other conclusions) follow:
- The Earth did not evolve. Had the Earth evolved from a swirling dust cloud (“star stuff”), radioactivity would be spread throughout the Earth. It is not.
- Supernovas did not produce Earth’s radioactivity. Had supernovas spewed out radioisotopes in our part of the galaxy, radioactivity would be spread throughout the Earth. Again, it is concentrated in continental granite.
- The Earth was never molten. Had the Earth ever been molten, denser elements and minerals (such as uranium and zircons) would have sunk toward the center of the Earth. Instead, they are at the Earth’s surface.
All three of these are really one single argument, not three separate points. Supernovas do indeed produce some of the elements in our universe but the heaviest ones tend to be produced by an even rarer process of merging neutron stars. A summary of how elements are produced can be found here:
It turns out that we have observed neutron star mergers in real time and we see exactly those elements heavier than iron being formed (including many of the radioactive elements)! (well the light took hundreds of millions of years to reach us). We know for a fact where all these elements came from and they did not come from the processes Brown describes. This is a great summary of a neutron star merger event:
As for the question of why aren’t the elements evenly distributed throughout the earth when the earth was first forming, that is a good question to ask. The answer relies on the properties of radioactive elements like Uranium, Thorium, Potassium and other Lithophile (or rock-loving) elements and a short accessible summary can be seen here:
