Don't know where else to ramble about these things, so I picked here.
I was doing some routine surfing of some of the science sites I try to follow when I saw an article about evidence for an expanding Earth.
Naturally I was curious. It seems plate tectonics isn't the only theory out there to explain how our geology formed. There is a theory that the Earth was smaller as recently as 140 million years ago (smaller Earth= smaller mass= less gravity= larger the math...140 million years ago would be smack dab in the middle of dino-age, but that's a whole nother aside!) The idea is that there is a continual flow from the interior of the earth that pushes old crust outward and drapes it in new crust. I'm still shakey on the details casue I just did a marathon hyperlink crusade and haven't digested everything yet. But I got to thinking what this would mean if it were true. Wouldn't such a situation require a continual generation of matter, and isn't that suppossed to be impossible?
Then I recalled another theory, one that claims there is a nuclear fission reactor at Earth's core. So I went in search of information. How would this effect the expanding earth idea? Turns out that there is a type of reactor called a "breeder reactor" that generates its own fuel until there is no more source of fuel to burn. Again, pardon the sketchy details, still nead time to digest. So, if a fission reactor exits at the core, and if it generates new particles et, what does this eman for the above stated theory. Not sure, because I got side tracked! I discovered that there is 1) a hell of a lot of uranium in Africa (specifically the general area where humans are suspected to have originated ...general area defined as several hundred/thousand mile area) 2) in West Africa a natural fission reactor existed some two billion years ago and ran for some undetermined length of time (possibly sevral thousand years.) BTW The natural reactor was a "breeder", hence the reason it came up in my search at all.
So here is what I throw out for thought :
Does anyone know how long radioactive waste from a nuclear reactor stays "hot?" Is it possible that all the primate variation that existed among human ancestors from several billion years ago to recent millenia was the result of radioactive decay of natural uranium deposits and the waste of the natural fission reactor in West Africa? If so, doesn't that speak volumes for human evolution? And, just in case you thought I forgot my original thought, if the Earth does expand, and its mass and gravity change, did the meteor strike really kill the dinos, or was that just a traumatic moment and what really did them in was a slow and steady increase in the Earth's mass/gravity? And, last but not least, if the earth is expanding, where the hell does the extra mass come from!!
Still researching, but I would love some input from anyone else.
More to follow, one day!
