You make me a headache. You just do not want to get the point.
We base our philosophies on different axioms - mine that thinking leads to useful ideas, yours, presumably, that the Quran is the Word of God. Those different axioms lead to different philosophies, and a variety of different conclusions. As long as our axioms differ, we will continue to disagree about a wide variety of things.
Ok. You seem to like astronomy. You say you have a very very good knowledge in astronomy - better
then the ancients.
Close enough. "If I have seen farther it is by standing on the shoulders of giants." -- Newton.
I saw an explanation in physics literature on why and how the earth orbits the sun. But could
you please answer me the following question:
Question: Why does the earth rotate around itself?
Did you ever see an answer for this question in any book? I think it is a good question
taking into account that all life on this earth depend on it.
After you solve this one - I have a few more others for you.
Lets leave the fancy words (quantum, chaos, and other latin stuff) aside for a while - ok?
I'm not sure I /can/ avoid fancy words completely - but I can at least try to explain what they mean. After all, it's said that you don't truly understand something unless you're able to explain it even to your grandmother.
Q: Why does the Earth spin?
A: Fancy-word version: "Conservation of angular momentum".
Nonfancy-word version: Have you ever heard of that law of physics, "An object in motion tends to stay in motion, and an object at rest tends to stay at rest, unless acted upon by an outside force"? It doesn't just work for pushing things around, it also works for spinning things; in a closed system, one where you're not adding new pushes, this thing called "angular momentum" is a constant. If you ever have a chance to play with a gyroscope, you can learn a lot about how angular momentum works, hands-on. If you've ever seen a skater doing a spin, when they pull their arms in they spin faster, and when they spread their arms out they spin slower - using a bit of math, based on the principle of "conservation of angular momentum", it's possible to figure out how /much/ faster they will spin when they pull their arms in, and that when they stick their arms back out, they'll go back to the rate of spin they started with - their rate of spin has been 'conserved'.
What does all this have to do with the Earth? Well, a long, long time ago, around five billion years ago, what is now the solar system used to be more like a cloud of gas. The bit near the middle happened to pull itself together with gravity, and started turning into the sun. The rest of the bits of cloud hanging around started falling towards the forming star; those bits that hit it became part of it, but some happened to fall at an angle so that they fell towards the sun and /missed/. Because of the way gravity works, they kept on falling, circling around and around the sun. The bits going in circles bonked into each other, and eventually settled into something like a disk circling the newborn sun. Then, the same way that the sun formed by bits of stuff pulling towards each other with their gravity, some clumps and bumps formed in the disk, and once they started forming, they pulled in more and more of the stuff. Now here's the part that brings us to the answer to your question - the bits of stuff that fell into these new lumps did so by spiralling and circling in, and when they did, they added new "angular momentum" to the lump they joined, which just means that they gave it pushes and started it spinning. After a while, all the bits of stuff finished falling into the bumps; the bumps and lumps became the spinning planets and moons we know today, and they were spinning from the get-go. Now there wasn't anything else to give them any big pushes, to speed them up or slow them down, so they just kept /on/ spinning. And, aside from the occasional bonk that knocks one thing or another askew, they've been spinning steadily ever since.
(As an aside, there's one last little complication about the Earth's spin - it's been slowly slowing down for a while. This is because the Earth isn't quite a closed system, and there /is/ some pushing being done on the Earth... by the Moon, using gravity.)
