Discovery channel

last night i was watching "the universe" program on the discovery channel, and i learnd alot.

it reminds me how much you can learn off of that, seriously.

back on topic.

There were alot of coincidence's on how earth came to exisist. Did you know there was another planet near earth, and they collided, and nearly doubled the size of earth? It was really cool to see the facts presented. Our planet survived because of valcanos heating our planet, not by magma, but by carbon dioxide. Venus has to much, Fail. Mars has to little, Fail. Earth, juuust right.

Comets hit the earth and gave us water. Under water valcano caverns started to create land. Than one cellular organisms (Life) started to pop-up in the ocean, likly sucking nutrients from the sea floor. THey eventually evolved and a billion years later after many changes, you have more and more complex cellular organisims, it came to a very small fish.

Then they talked about how the human race is affecting our planets climate, and that we are not making a huge contribution. Greenland, which IS a huge slug of ice, is-shrinking. The ice sheet is receiting, making it thinner. This is a process that happens like a cycle in earths history over millions of years. Did you know that the north and south poles used to be jungles?


That ends my discovery lesson, maybe ill post more of these

Like you said about Earth being just right; I believe that there may be no other life in the universe; and those infinite amount of other planets/solar-systems/galaxies were all failures.

This really explains the whole 'The perfectness of Earth is just to much of a coincidence for there not to be a God' Maybe it's because so many other planets were 'attempts' at this.

Also, discovery channel is pro.

Hmm, can you explain more deep the things about the planets colliding? What do you mean by Venus and Mars "Failing" (As in what term of failing, because they are still there) and by the way, its "volcanos".

And about us affecting the earth climate, I believe everyone in here is well awared of Global Warming.

The claim that some other planet hit earth and doubled the size of the earth is at best a hypothesis. Where are the remnants of this other planet? Unless you mean that it was something that created the moon. Two planets with the same mass and size are going to obliterate one another. Not sure what you mean when you say our planet survived through carbon dioxide alone. Survived from what?

The first organisms were extremophilic bacteria that used sulfur compounds near volcanic vents for their energy, they didn't suck nutrients from the bottom of the sea floor. I agree with you that global warming is a natural cycle but never in the history of the earth has the rate of warming been so rapid as it was in the late 1800s and today.

And the north pole and south poles have always been icy to some extent. Antarctica used to be green, but that was when it wasn't located at the south pole.

What perfectness of our planet? Just because our telescopes cannot detect earth-like planets at the moment doesn't necessarily mean we're alone in some big cosmic void. Absence of evidence is not evidence of absence.

Life is beauitful and rare, I am fascinated when I learn more about it but I find it funny that people actually run to religion even after they see the facts, it just shows how much brainwashing works.

[COLOR="Navy"]well when earth collided with theila, earth became larger, and theila (spelling?) exploded and earth increased in size. An asteroid perimeter was created around earth and eventually they all fall into the earth's atmosphere. Do i need to explain why they didnt have a mass effect on earth?

Earth "survived," as in had conditions for life, because carbon dioxide heated the planet.

Sorry, i dont remember too much. Im only 15 >.<[/COLOR]

to lylac, was the disagree ing necessary? im open to constructive critasisum, but i kinda feel attacked.

i just wanted to present some cool facts about the discovery channel program, The Universe, not prove we are unique ect.

Did you even read my first sentence?

I was referring to how Earth can support life.

@xCenario: He means how Venus and Mars cannot support much life if any.

This can be called as the situation of black swans. For a long time, Europeans believed that all swans were white. And that notion only held true as long as their discovered world contained only white swans. But then Australia was discovered and black swans were discovered. So the perceptions of the world and what swans were had to change.

This can be represented as any event that happens out of the box of expectations. We find casuality in all events based on past experience. But the biggest events cannot be predicted because they just never happened before, such as 9/11.

What I want to say is that as long as we don't find any proof of anything else existing we can say that we are the only thing alive in this universe. So the other living creatures that you say that may exist, have the right to say that too.

That would be a closed-minded and egocentric viewpoint of us in the universe. There's already evidence of salt beds and past water on Mars and lakes of hydrocarbons on Titan and elsewhere. There's no proof, I agree, but there's data and evidence.

I didn't mean to attack, I just wanted to comment on some stuff otherwise there would be no point of discussion other than a few posts of 'wow, cool.'

Look, im no expert in astronomy, I don't study the cosmos and from what I just saw neither do you. And that wouldn't be close-minded and egocentric because as you may know, life in another planet is just a theory for now. Such as warm-holes and having another parallel dimension simultaneously to us, is a theory, unproven theories until today. So if everyone still have believes that theories are proven wrong like it has been for the entire existence of Science, I have the right to anticipate that this one will be wrong too.

Now if you felt a little bit offended by my post, or if you felt like im an idiot for saying such. Then go ahead and continue to follow the same bit of info they give you in the internet of little robots landing in Mars and finding bits of particles that may bring the possibility of there being life in the planet. Go study the cosmos and complex world of the universe, I will be waiting for said proof to arrive. But in the meantime, I mantain my opinion of there not being any other life in the universe.

I am not offended, nor am I calling you an idiot. I'm also not clueless when it comes to space science because I've taken astronomy and physics classes in university. There is no need to get all defensive because this is, after all, a discussion and a debate.

Technically, all theories are unproven and that's why they remain theories and not become laws. However, theories are based on evidence. Worm holes are theoretical, but they're sometimes solutions to general relativity problems. Life on other planets is also theoretical, but there is evidence to support it, and there is nothing truly special about life. Miller and Urey created essential organic molecules such as amino acids just by using a spark of electricity and chemicals you can find in toilet cleaners. You've also got bacteria living in extreme environments that would easily freeze or boil a human alive. You've got 100 billion galaxies in the universe, each with an average of 100 billion stars. If none of those 10,000 billion billion stars contain any planets without any form of life, well then the universe is a pretty big waste of space to say the least.
