It has facts. One I particularly appreciate is that he mentioned that if you put a Crook's radiometer in the freezer, it goes backwards. Haven't tried it with mine yet, but interesting science. Next, it contains some scientific details well explained, but it also contains models that are poorly constructed, for example his estimation of the forces acting on the end of a tectonic plate are so poor as to being useless because his model is essentially a straw man. But most importantly, his writing does not establish there was actually a flood.Dr. Walt Brown's book is full of facts that describe in scientific details what caused the flood and its effects.
If you read it carefully, everything about the alleged flood starts with the assertion that <something> happened, but he has not established the fact of it happening. Anyone can write that all comets and asteroid zoomed off the surface of the earth, but we have discussed here the evidence that shows that asteroids were never on the earth. Anyone can write that there were massive chambers full of water, but he gives no evidence that unambiguously shows they ever existed. Anyone can write that radioactive elements were produced a few thousand years ago, but his mechanism does not have the required energies, and we can see those same elements being formed in stars, which do have the required energy.
Mr. Brown has a nice story to sooth christian fundamentalists, and there are some good moments of science education in it, but if you want to take it as a whole, it's not true, it's not a theory, it's not even a hypothesis actually, and the premise of what his flood can do is not directly supported by any evidence at all, so I would recommend being quite careful about calling it your truth, because it's not truth in any honest sense.
The kindest thing you could call Mr. Brown's hydroplates is science fiction.
I don't 'like' evolution by natural selection. You don't see me ignoring that.That you continue to ignore everything that you don't like is your own problem.
