Seventh Earth

[chequerboard]

Hi,
I was wondering what anyone thinks of this website on the possibility that the planets in our galaxy reflect a timeline?
It seems pretty well researched.

I'd say that a lot of effort went in to making a nice looking web-site for this idea.

Personally, I think the idea ignores a lot of knowledge and science in order to achieve something that might make good background for an interesting fantasy novel.

The idea is too way-out to make it worth trying to debunk.

Very slick design, with lots of terms that sound similar to those used in conventional theories of tectonics, etc. but with some pretty fantastical premises, that are certainly not supported in any substantial way by what's presented on the site.

Even on its own vague terms it is scarcely convincing, but there is a symmetry to the gross concept that is quite appealing to a mind seeking order in a not especially orderly solar system.

There are so many aspects of planetary sciences that are blatantly disregarded by this site that it seems incredibly unlikely that this is anything more than well-illustrated "crankery." Given that the site is not specific enough in its claims or its explication of a so-called "theory," it is impossible to refute -- as it is hardly saying anything that can be verified, proven or disproven....

Well anything is possible, but remember about 1000 - 2000 years ago, when a certain somebody said the earth was round, and at that time every one believed it was flat, and the center of the universe!!

Interesting find. i would go along with it.

i refuse to believe in that theory, because of some holes in it, like that metallic hydrogen. it doesn't exist normally as metallic; only under extreme pressures (jupiters pressure, imagine about that: at 1,000 km there's 2,000 bars pressure; i think earth nor mars can do that easily. besides both planets are R-O-C-K planets) i hope my clarification made some sense... i'm not even sure myself what i wrote... (just quick typing, no thinking involved)

Ooo, almost forgot: where to get all that hydrogen/nitrogen/neon/argon/krypton? for example Jupiter has krypton 2.5*10-9 per atom of hydrogen, when sun has 9.2*10-10

I guse i could go along with you point to it has some promising points.

poor me, it was from space towards center what i meant... anyway, i claim seventh earth theory (though it's quite imaginative) to be.... well... too imaginative to be true

Honestly chequeredboard...going off the original question...I see the planets as much more than in sync. I gather eaach in their own has a different lapse. Perhaps, one or two may have been the first to finish and begin all in time...though, the few I personally view on a clear night is always a most beautiful sight

Interesting Idea. Very nice website. I wouldn't be suprised to see a theory stateing that the Gas Giants were a falied companion star to the sun, like the Alpha Centauri system. I think there is as much evidence for the timeline as presented, in reverse, expanding sun blowning gas to the outer planets consuming the inner planets to feed the expansion, ( I think that is the currently accepted scientific theory?). I don't think either theory contributes much to current observations of extra-solar planets.



Nice picture

[KeiZka]

I don't know about if gas giants are failed companion stars to sun, but maybe if they all were combined, they would have sufficient mass to ignite fusion in their core. or maybe not. hard to say.

[damienpaul]

So if this theory is to be believed, (i am still not 100% convinced) then in some future time, there will be a gas giant where Mars is, a 'mars' where Earth is and an 'earth' where Venus is....what is the implication for life in all of this.

I think I may have missed it, but what is teh timeline for all of this?

[KeiZka]

it was stated somewhere upper this topic: quite flashy lie. I'm also against this, it breaks too many laws of nature to be true (like getting massive amounts of hydrogen from nowhere? yeah, right´, i'd like to see that happening...)

[Betelgeuse]

I think it's avery interesting idea, however, I do not agree. The website does have promising points and ineresting views but overall, I don't think there is a strong enough argument (by far not as strong as the big bang) for it to actually persuade me to believe it - if you understand what I'm getting at!!

Hi All

The web-site is just plain kooky. If the terrestrial planets are in an evolutionary sequence with the gas-giants it would be in reverse - the terrestrials are exposed cores of gas-giants, like Marvin Herndon's theory, or the Capture Theory which has Earth/Venus form from a gas-giant collision.

According to work done on migrating planets if a Neptune/Uranus class planet ventured too close to the early Sun it would lose its H/He envelope through hydrodynamic escape and the enhanced solar-wind. To imagine that such an envelope would appear out of nowhere is just nuts.

The sole basis for the theory in question seems to be "Earth expansion" which attempts to explain the same geophysical evidence as plate tectonics. Personally I think plate tectonics is the more parsimonious. Mass creation and energy from nowhere, as required by expansion, are big violations of physics as we know it. I'd want a lot more evidence before giving any such theory the time of day.

To invoke energy creation at the Big Bang as analogous is senseless ignorance - energy creation only happens when the conditions are at extreme density and pressure allowing a GUT phase transition. Such just don't happen in our current Universe because nothing can contain them. Not even star collisions let alone planet centres.

Opt for an easier explanation - plate tectonics. It may have problems but smaller ones than Earth expansion and mass creation.

I looked at that page again, with utter disgust.

A further contraction will cause the original entry point and it's antipode to converge. They are the two weakest points on the planet surface. When they meet, the crust ruptures. The result is an enormous ball of metallic hydrogen, which settles and follows the now almost entirely parallel lines of the surface magnetic field of the empty shell deep inside it.

That was from the website. Note this part:

It seems, that the author of this "Seventh Earth" hasn&#39;t done his homework about Earth&#39;s endogenic happenings, or my school books are obsolete, because I&#39;ve never heard that Earth holds anything else besides minerals and molten stone, or magma, refer it any way you want, in it&#39;s astenosphere. And I highly doubt that magma would "separate" into hydrogen. Maybe it&#39;s possible, but still highly doubtable (God I love debunking this topic <_< ) And by the way, I&#39;ve always thought that Earth&#39;s magnetic field has lots to do with astenosphere, and convection which happens inside there? To scientists knowledge, both Saturn and Jupiter have magnetic fields. But if to believe this theory, which is quite baffling because it makes at least me think, that Saturn and Jupiter ("Former Earths") had all this hydrogen come from interior of their rocky crust. Yes, they both have rocky interior somewhere deep, but they still have convection going on, forming beforementioned magnetic field. But, to gain such amounts of hydrogen, you would need to change everything below crust into hydrogen in order to get that theory&#39;s mentioned necessarily hydrogen. And let&#39;s not forget that before Earth would change into gas giant, it would have to go through Mars -phase, where it has NO magnetic field which this theory requires (Mars, as you all well know, doesn&#39;t have such global magnetosphere as Earth does), and this transition from Earth sized planet to Mars sized planet, is so damn unbelievable. If Mars was once like Earth, how come it has decreased in size? Or why it has less mass? And to make things even more immeasurable, where does it gain all that mass to become something like Jupiter? Truly, there&#39;s been found that exoplanet, which is almost big enough to be giant itself, and note that this is rocky planet, and isn&#39;t aforementioned planet 14 times as big as Earth(can&#39;t remember, was it in mass or in diameter)? It&#39;s almost as huge as, was it Uranus or Neptune?
About plate tectonics... I&#39;m not going to talk about them, as didn&#39;t qraal. I understand him, quite well. Tectonics aren&#39;t that big in this, only that losing mass/gaining mass/getting hydrogen (and metallic) out of nowhere...
Oh, damn, I went into rambling again, really sorry about this... But, I truly like to debunk this.
