Someone posted this video elsewhere taking the position that geology says the earth is growing over time. I don't know enough to know, but found it interesting. Hopefully Rockdoc and others can view and make comments. I've never heard this idea before.http://www.youtube.com/watch?v=oJfBSc6e7QQ

Just looked at the video, the first question that jumps out is "where did all the sea water come from to fill in the oceans?"
Did it just appear like magic!

I've got a better question.......86 million barrels of crude being turned into heat, energy and
co2, every day. A major percentage of this mass escapes into space. Is our orbit changing due to the decreasing mass of the earth? Anybody? 86M x30x6x365=56 trillion pounds +- every year, of course decreasing backwards in time, but it is still alot of angular momentum being lost. No?

Hmmmm.....I read that three times and I am not sure it is talking about heat and energy.

A planet is a closed system as far as mass goes. It cannot grow.

Except situations like how our moon formed, after a planet collided with the early Earth and a big molten blob plopped out and our moon formed from the debris.. the net effect probably added mass to the Earth, since scientists believe it was a Mars-sized planet that hit us and the Moon isn't Mars-sized so the extra mass went somewhere..

[peeker01]

No strings, my question is one of mass reduction, not growth.

The gravitational force at the surface of the earth places a limit on the size of land animals with elephants being the largest today. Elephants are significantly smaller than the largest known dinosaurs of 65 million years ago, which were huge by comparison; these dinosaurs could not possible have lived if the gravity was the same or greater back 65 million years ago. Their massive bodies could not have been supported by their bone structure. The logical conclusion is that gravity was less 65 million years ago.

Could this fit in with the idea that the earth had half the diameter 65 million years ago as Neal Adams suggests? It could if you assume that as the earth doubled in diameter since then it also increased mass in proportion to its new volume as calculated using its new diameter plugged into the simple formulas for the volume of a sphere. If you go back in time 65 million years, shrinking the diameter by 1/2 then the volume would shrink by 1/8, and if the mass decreases by 1/8 also, then surface gravity would have been 1/2 of what it is today. This is interesting because if the mass 65 million years ago and the mass today did not change, but the diameter increased, then surface gravity back then would have actually been 4 times what it is today, making it even more impossible for dinosaurs to have existed at the sizes their fossils show was the case.

So the size of the dinosaurs suggest that Neal Adam's idea of an expanding earth has validity. It also suggests then that the earth's mass does increase with its diameter, and that surface gravity increases by a factor of 2 when the diameter doubles. This opens a whole set of questions about how the additional mass gets here, and it also suggests that if the growth continues, eventually gravity will become overwhelming for all but the smallest land animals here on earth.

Neal Adams presents additional visual evidence using other planets and moons at this site and also details some of his arguments at the bottom of that page:

I was curious about certain "facts" put forth in the video, to see if those are in fact "facts." The video states as fact that all the continents, including the poles, fit perfectly together. Is that true? The video then states as fact that the sea floor is 70 millions years old while the continental land masses are over 100 million years old, thus implying the earth is expanding. Is it fact that the sea floor is much younger than the continents? It states the gorge marks on the ocean floor point direction of movement (east and west). True? The video states that certain forest in the upper continents are all of the same type, even though now separated by oceans and that remnants of those forest have been found in the north pole (I believe it said). Is that a fact?

Peak Oil is a blog about geology and economics. Not hokum flat earth, hollow earth or earth is growing BS.

$this->bbcode_second_pass_quote('Plantagenet', 'N')o. The earth is not expanding.

This is a curious idea from the 19th century that can be easily disproved using modern geophysical data on plate motions and subduction rates.

The earth has had oceans for billions of years. Some of the water in the oceans outgassed from the earth as it cooled after planetary accretion. Other parts of it may have accumulated from comet impacts on the earth.

$this->bbcode_second_pass_quote('Pops', 'T')ake a pill:
$this->bbcode_second_pass_quote('', 'T')he Open Forum is for other topics that may be of interest or benefit to our members.

Well, I'm still interested in verifying the "facts" put forth in the video that I posted earlier. The benefit of forums like this is people with vast experience and knowledge in particular areas. I'm not even close to a geologist, so, I would hope that some of our resident geologist would indulge me for a second here. There are many things I find interesting for fun.

[Oakley]

$this->bbcode_second_pass_quote('steam_cannon', '
')Yep and if they post poor quality ideas they are going to openly get knocked down. I know you're responding to my bold text about this being a geology and economics website. Of course we don't need to discuss only Geology or Economics. Personally I think other topics that relate to the community are worth discussing. But tinfoil hat topics like the old "out of this world" section took away from the forums quality and the subject of peak oil in general which has had a lot of good research go into it. So I'm glad the "out of this world" section is gone and I'd rather the open discussion section doesn't turn into the same thing. Tinfoil science is bad science and conspiracy talk makes me itch.
