Birth of the Earth
Our Earth was spinning very fast when it was spit out of the Sun as a molten glob four and one half billion years ago in the initial explosion.
Venus was spinning in an opposite direction when it was spit out and is still doing the same.
The Earth settled down in a very fortunate orbit for the existence of life. At 93 million miles distance from the Sun it receives just about the right amount of radiant energy.
Its spinning has gradually slowed down over these billion of years and is now settled into a comfortable 24 hour rotation at the present time.
It will be millions of years in the future before it slows to a complete halt as our less massive moon has already.
In the days of the dinosaurs when the Earth was spinning faster, the days/night cycles were shorter.
Going back a couple of billion years further, at one time the Earth was spinning so fast that it may have had a ring around it, similar to Saturn.
The Earth was much more oblate at that time, the oceans were more concentrated around the equatorial zones, with much more shallow ocean depths at the poles.
The oceans are still deeper at the equator then they are at the poles and the Earth is still slightly oblate.
It seems unlikely that the earth was spat out of the sun. Earth has a huge iron core. Stars do not produce iron until the end of their life and it appears that our sun has not reached that stage yet.
It was a good film altho my rather intelligence states that you your bad and #blameben so sad so sad:(
Great film, but if I hear the word "astounding" one more time I'm gonna scream.
Like being recited your favourite story for the umpteenth time as a child, watching this documentary had the same reassuring effect.
You've heard it all before, but not in a bad way. It's interesting, yet simply explained. If this sort of thing already interests you, then you probably know much of what's said. Despite that, it's still fascinating to hear it all again.
we just have to keep the balance and take care of the earth
I find it disturbing that no mention of Bill Hartmann was made for the theory of the origin of the Moon. It was in 1975 thatHartmann first proposed that the moon may have formed by an impact of the "Mars-sized" planet. His theory was then tested later on and confirmed by computer models!
Good comments from everyone. Another good doc is "The Privileged Planet"
@ Epicurus ...
Yes, there is something more I want to know. I wanna know what is the origins of life, the universe and everything.
@ David Pirtle ...
How do you know The hydrogen and helium in our solar system condensed shortly after the ‘big bang’, as energy began to cool. All the heavier elements were fused in stars which died, and the resulting nebulae from those dead stars is what forms new systems like ours?
I'm not saying that's not what happened, I'm just asking how it is you or anyone else could possibly know?
Either way, the little evidence we have does not constitute proof so saying that you "know" is not entirely accurate, is it?
@ dude7474 ...
Don't be silly, whatever God might be it's of Love and ain't gonna strike anyone down.

I think they just never said the word "nebula", because they had pictures of them during the scenes explaining how the sun formed.
the swimming baby?!?!?!?!
Post Script - Thank you Vlatko for putting all this information at our fingertips, you're making the world a smarter place, and I think that makes it a better place to live. keep up the good works.
The Sun did not "spit out" the earth, if it did the planet would be so intensely radioactive that life could never take hold. Venus is spinning backwards because of a massive impact that reversed it spin. If the planets where already formed when the nuclear furnace that we call our Sun went critical, they (the planets) would've been destroyed. I don't know where this doc came from, but it is horribly inaccurate. Just because something sounds right , doesn't make it science. Try doing the research and subjecting the hypothesis to the scientific method, BEFORE making the doc.
[00:46:50] Sometimes its better to not follow internet links put up here.
[00:49:14] I have to limit myself to listening only to websites that
recognise the importance of disseminating info that is based on rigorous usage
of the scientific method.
[00:54:51] Everything said (as well as how it is said) has to go
thru rigorous peer review.
@Cliff T, I don't think the expanding earth hypothesis is laughable. I think it has absolutely no evidence to support it. Evidence for plate tectonics and Pangaea is extensive, and most would say overwhelming.
@intbel The hydrogen and helium in our solar system condensed shortly after the 'big bang', as energy began to cool. All the heavier elements were fused in stars which died, and the resulting nebulae from those dead stars is what forms new systems like ours.
@princeton Its not accurate to say we've never found water while investigating comets. It is fair to say we have found far less direct evidence of water than was first exected. However, what the documentary was referring to was not direct observation of water, but observation of hydrogen isotopes through spectroscopy.
hi vlatko this link is not working on 11/11/2010 hope to watch this one soon it sounds interesting
its on Google video in 3 parts, maybe the link could be replaced?
enjoyed it thoroughly.
this is my first post so thanks for a great site Vlatko, im on here almost every night.
@Intbel....You should look into the universe with stevan hawkin!
So ... our planet began as a dust cloud? Okay - where'd that come from, please?
The dust being tiny chunks o' this an' that - sounds similar to a cloud o' sand ... which was originally a chunk o' rock.
No answers to origins at all in this movie.
I also question "Our only safe haven" - that is an assumption based on what? Nothing as far as I can see.
Sorry, guys, I have learned nothing from this documentary.
@Cliff T
I'd consider Pangaea a little laughable but the continents seem to fit together rather nicely. :)
But that's why science is so great. We go with the best theory until it's proven wrong, or added to. Everyday something unimaginable could be learned.
@ Lester W
I think you are referring to the fact that if you were to look down at the plane of the solar system from its 'north pole' you would see the planets orbiting the Sun counter clockwise, and rotating on their axis counterclockwise. Except for Venus. Venus would be rotating clockwise as it orbited the Sun counterclockwise. Scientist think this is due to some traumatic event in the far past that affected the planet while it was being formed. Perhaps a collision with another planet, or a huge asteroid impact caused this odd behavior. Hope this answers your question.
Earth moves toward the sun, thanx figured it out. I'm dum.
You know, if it's found that the Earth is growing, this will all be blown apart and they will have to rethink how the universe formed to how it is today. I may be one of those that accepts that way of thinking but I'm in a minority which I can accept, but I would encourage people to look into it more rather than just laugh at the very idea of it. To me, Pangaea seems more laughable, but I still acknowledge it as the current accepted theory.
@ princeton, you are certain that you mean comets or are you getting mixed up with asteroids? (Apparently some scientists have observed asteroids with tails made of ice, when it was previously thought they were too close to the sun to retain water in any form)
Oh, and by the way, EZ try to look up the name on Google. Certainly when it's first posted.
I personally use orbit to download the file. I then convert the .flv to an avi file. After that, I use windows media player to open up the file because my settings in WMPlayer are set to "Share" to xbox.
I then watch them on the big screen. :)
