I have sat on the sidelines on this one so far but feel compelled to jump in now. I haven't looked at the original post or the web site that talks about the expanding universe applying to the Earth. But lets look at it this way: 1. The previous comment made about having rift zones with new oceanic floor forming in both without having Earth expansion could be. But while new oceanic crust is being formed throughout the mid oceanic rift, older crust is being destroyed by subduction. This is well evident by the violent volcanism along the subduction zones. 2. There is no evidence of the Earth having gone through our currently experiencing expansion. Granted on the large scale, the universe is expanding but its individual components remain static in volume. If everything in the universe were expanding (including Earth) there would be no relative expansion and it would only appear that the speed of constants such as light was slowing down. Do I make sense with this?

Thanks David, I enjoyed reading that. A part II on this and perhaps what I find more fascinating is that this theory seems to explain aspects of Lunar and Martian geology that can't be explained by Plate Tectonics, because there isn't any there. Valis Marineris has always bothered me. I never liked the water theory as the valley is just far too wide to have been caused by water. If you haven't looked at the Adam's videos that refer to Mars and the Moon from the original post's link I invite you look at them, if nothing else they are a different way to explain them. Also I don't like that we have expansion joints in both the Pacific and Atlantic Oceans that appear to expand into each other, and why are the Ocean floors made up of such young rocks? They should be much older if in fact the continents have been drifting for as long as the Plate Tectonics Theory would have us believe. We have rocks on land that are Billions of years old, yet right off shore they are no older than 125 million, does that make sense? Subduction should provide a more even transition in the age of rocks. Certainly the Pacific Ocean's floor should be much older than the Atlantic Oceans floor, but it's not. I am still lost as to why we didn't figure out the South America and Africa fit together until about 70 years ago, every school child knew it, hmm, our maps weren't that bad in the 40s and 50s. Plate Techtonics is still a very young science. http://geology.about.com/library/bl/maps/blseafloorage.htm BTW: Adams is not the only person studying the expanding Earth theory, there are others, it is not as fringe as you might think. I personally don't have any issues with the current Plate theories although I try to be open minded. Often the real breakthroughs come from the fringe, ask Galileo, or Einstein, or Hubble who were all ostracized by the mainstream at one point in their careers before they were shown to be correct. I'm just playing Devil's Advocate, I think it's a fascinating theory and may be correct about a few things, but I'm not a Geologist, although I do know a few if that counts.

Robert: It is my understanding that gravity can counter-act, and even overcome the expansion. Which is why they theorize that Andromeda and the Milky Way will someday collide even though the space between them is increasing. I'm bored, might as well. _______________________________________________ Utah-Astronomy mailing list Utah-Astronomy@mailman.xmission.com http://mailman.xmission.com/cgi-bin/mailman/listinfo/utah-astronomy Visit the Photo Gallery: http://www.slas.us/gallery2/main.php Visit the Wiki: http://www.utahastronomy.com
