I read that if the earth was just a very short distance closer to the sun, it would have been too hot - or just a very short distance farther from the sun and it would have been too cold. As it turns out, it's just right.
Can't remember the distance, but it was really short. If anybody knows it, I'd love to be reminded.
Hey Barb,The distance from the Earth to the Sun varies by a bit less than 3.5% over the course of a year. To give you an idea how much difference that makes, in June, the Northern Hemisphere is about 3 million miles farther from the Sun than it is in December.
Inverse square law, and things like that. In June, the Earth gets about 0.9989 times the radiation from the Sun that it gets in December.
If the distance veried by 10%, then it would be about .99 times the energy. That might make a difference...(Barbarian checks)... No, it likely wouldn't matter.
So the "Goldilocks zone" is wider than most people would expect.
Now.....for other life in the universe we look for water and oxygen...but ANY life form could exist that may not need either water or oxygen.
Yes and I heard our moon must be in its exact orbit else chaos on Earth.I read that if the earth was just a very short distance closer to the sun, it would have been too hot - or just a very short distance farther from the sun and it would have been too cold. As it turns out, it's just right.

I also saw a show with a physicist who said the vast amount of mass formed in the nano-seconds of the initial Big Bang and the physicals laws governing this mass were so complex and almost instantaneous(as if created as spoken) that it is inconceivable that if one saw the data remain an atheist.Also, when the Big Bang happened (as in Genesis) the amount of every chemical was exactly right. The force of the explosion should have immediately caused it to implode -- instead it didn't.
Alas, the big bang theory has been "proven" to be correct and is, today, accepted as common knowledge. Is this good for science?
Are they happy the big bang theory has been accepted?

Hi everybody!
As a physiscist, I would like to share what I think is the strongest rational argument for God's existence, i.e. the mathematical representability of the natural laws.
Just the earth and the thin blue line of air that cling to this one planet.If the universe and mathematical relationships were different, the universe would be uninhabitable by mankind. The universe is fine tuned to make it a suitable home for people.
Just the earth and the thin blue line of air that cling to this one planet. The rest is nearly infinitely hostile hostile.
I am not a knuckle head going to Mars unless they find an ocean there.Indeed. The rest is just there to help make earth a cozy place.

What kind of strange medical things? Just curious.Doctors keep finding strange medical things in astronauts that have been in space for months on the space station. I can't even imagine what going to Mars for decades would do.
