The rotation of Earth around the Sun.Just dumb luck or...?

[Papay]

Life is based on Liquid water.Without Liquid water Life,as we know it, cannot survive.To keep water in liquid form you need a temperature between 0-100 degrees celsius otherwise Life seizes to exist.This is the temperature of Earth and this is why Life survives here for so long.Of course we take this for granted and we dont analyze it.
Lets hypothesize that the maximum temperature that could be measured on this universe is 10.000.000 degrees celsius(the core of the sun is supposed to have this temperature).From these 10.000.000 degrees the 9.999.900 degrees are hostile to life since Water can not emerge in Liquid form.Luckily here on Earth we have the perfect temperature that helps Life survive without problems.The chances for this to happen are very low.But here comes the Best part:Earth's rotation means that this perfect temperature is sustained indefinitely.What are the chances for this to happen?Of course science will play down the fact but in reality if Earth was just a little bit eliptical then Life could not survive....

Its a random fluke no doubt repeated somewhere else

Given this is in the Ethos I have to assume that after the ellipsis you left out the following "ergo God did it."

Are you taking a scientific position here Papay? If so it should be in the Athenaeum. Inhave to say though that's got to be the worst version of fine tuning/Rare Earth that I've seen. By necessity, the Earth's average temperature must be greater than 273K otherwise we wouldn't survive. Without the Earth's atmosphere it would only be at about 253K or -20 celsius if you prefer, this is called the Greenhouse effect which I'm sure you have heard of. Without liquid water, life usually dies. There's also the possibility that, less that 20 years after the first exoplanet was discovered, we have found an Earth-like planet orbiting within another star's habitable zone. http://arxiv.org/abs/1105.1031

The best comparison is to Venus, which would otherwise be able to sustain liquid water if it wasn't for its massive greenhouse effect. In fact we are almost certain that Venus did have liquid water on its surface in its early history. This is because we observe an increased concentration of Deuterium molecules which can only be explained by the evaporation of water, and subsequent destruction of such by UV radiation. This is also probably why Venus has such a large greenhouse effect.

On the point about ellipticity, do you mean the Earth, or the Earth's orbit? Because the Earth's orbit IS elliptical, as is every other body's orbit in the Solar System and probably in the Universe (that has a closed orbit). The orbits of most planets including the Earth's are approximately circular, however it was realised by Hipparchos (The Greek Philosopher not the satellite) that they couldn't be perfect circles, he then adopted a geocentric model, because he thought that heavenly bodies had to move in perfect circles, this is one of two reasons why the geocentric model of the Solar System survived for so long. It was only when Kepler used Tycho Brahe's observations of Mars for the Czech King that it was realised that the orbits of the planets were elliptical.

Actually, the entropy drive provided by the Sun is far more important that keeping the planet at precisely it's current temperature. There is a fantastic video describing this somewhere on the internet, though I'm afraid to say I can't find it at the moment. As long as the initial conditions in which life arose were suitable, life now appears capable of surviving at temperatures below freezing, or well above current levels. You're also drawing a hypothesis based upon a single sample, which is a fairly dodgy premise to begin with.

... as for the Earth's rotation. What? The Earth's orbit is elliptical. If you're referring to it's shape, then I have no idea what you mean, as all gravitationally bound objects are spherical(ish) by virtue of having sufficient mass.

Actually this thread belongs here: http://www.twcenter.net/forums/forumdisplay.php?f=18

Papay's posts have dropped to the point that even someone with no knowledge on the subject could look at his post and say "that is a load of !"

If you say that the earth supporting life seems unlikely when it already does... That's confusing: How can you attach a probability to something that appears to already be so?

Probabilities are for predicting the future; and so how likely the 'improbable' is when it's right in front of you is a non-issue. That's the way it seems to me.

For example. I toss a coin. It lands on tails. The chance of it being tails is now is always 100%, so no point talking probability. The chance of my next (future) toss landing on tails is ~50%.

Or I enter a lottery, and I win it at 50m to one odds. The odds are no longer relevant from the moment I win.

Finding life on other planets is the only sensible use of predictions about planets producing life.

wow just stop right there.

There are whole textbooks that describe why the earth rotates around the sun. I am quite sure philosophers and scientists have discussed this topic before analyzing every bit.

Nah, the universe is really big.

See ? even God says you're wrong

You're actually understimating by several orders of mangnitude. The coldest possible temperature is 0 kelvin, minus 273 celcius. The highest we understand is 1032 kelvin.

Of course science will play down the fact but in reality if Earth was just a little bit eliptical then Life could not survive....

The Earth's rotation IS eliptical, not circular.

Of course science will play down the fact

Despite the fact even you are vastly underestimating how many variables had to be just right for life to exist, it's still so likely it's almost inevitable. There are approxiamtely 250 billion stars in our galaxy. That's 250 billion chances for the right conditions in our galaxy alone. Here's our galaxy:

And that's just our moderately sized galaxy. This is our sector of the sky within a few hundred million ly:

There are approximately 250 trillion stars in the above picture. Yet that's still a miniscule fraction of the observable universe. So small it doesn't even appear on this representation of the observable universe. I won't even hazard a guess as to how many stars are in it.

And we don't know anything about the universe beyond that edge. It could be infinite.

[MathiasOfAthens]

Like Ireland said the chances for life or even a habitable world are highly likely.

[Sphere]

I'd say the probability that life requiring liquid water to survive would only develop on a planet which has liquid water is about 100%.

You're lying.
The Earth is elliptical.
The diameter of the equater is 43,000 meters larger than the diameter of the poles.

The chances for this to happen are very low.

You're lying.
Actually given the size and the most common elements of the universe the chances are guranteed and it is guranteed that there are millions of other similar planets.

I am quite sure papay was not referring to the shape of the planet but to the orbit of said planet around the sun.

I thought that at first, but I regarded that as being so retarded and obvious that I couldn't believe it.

The Earth's orbit is very clearly elliptical, there are three year old's who know this.

I, too, have seen the message Papay is trying to spread here. The FSM is real. He created this world and the universe. We should all be thankful of his noodly appendages holding us down. You people and your religious belief in gravity need to wake up!
