Logic is my book on gravity. Just because there is mathematical agreement doesn't mean you understand the mechanics behind it all...just that the sums add up.
The way I have it is that gravity pulls the Earth towards the sun and brings it round the first corner when the planet is centrifugally discharged. It then soars out on its long path away into space but this loses its momentum and the motion changes into free fall. This is when the planet is again captured by gravity and pulled back towards the sun. This is why there is always an elliptical orbital pattern and why planets that erupted out of the sun cannot wander away from it...The clues are all contained within 'pendulum' motion...but it is a bit too advanced for you yet.
Better to just follow the accurate teaching of Jesus Christ and leave the heavy stuff to those righteously trained.

Actually....
... of whats the use.
So, what you're saying is that gravity pulses, the sun pulls on the earth when the gravity is on, then the earth moves away from the sun until the gravity is turned back on again?
Gravity is constantly pulling on the earth and the earth's movement is always pushing against it. You need to study the theory of gravity a little more and stop trying to insert your mythology into it.
I'm no scientist so I have a couple of questions:
1) How does "free fall" work in space?
2) Wouldn't this idea mean that the speed of the Earth's rotation would change a bit? Wouldn't the effect of this change be noticeable on Earth?
3) What the fuck does this have to do with what Jesus taught?

Many people know more than I do, but I know more than the average guy on the topic and will try to answer your questions.
1) Free Fall is not no gravity’. We don’t know a place in the Universe that is not subject to any gravitational force at all. The closest we can come is where gravitational forces balance, but they are a rare exception. For the purpose of this discussion accept that every place is subject to the pull of gravity.
When we fall, whether on Earth or in Space, we accelerate under the pull of gravity. We don’t feel the pull of gravity, though we sure do feel the impact when we hit.
If we’re standing on the surface of the Earth, we feel gravity (1g, 9.8 m/s2) because we’re not in free fall. Our feet press down against the ground, and the ground presses up against our feet.
The late great Douglas Adams defined flying as throwing yourself at the ground and missing’. This is a pretty good definition of an orbit.
At the height of the International Space Station, Earth’s gravity has 89% of its strength at Earth’s surface. If you stood on a tower next to the Station and dropped a rock, it would hit the Earth’s surface a few minutes later. The reason the Station doesn’t hit the earth is that the station is also moving under the effect of its momentum. The curve of the earth drops away at the same rate as the Station falls. The station falls eternally. Or until minute traces of atmosphere slow its momentum.
Every orbit, whether Earth around the sun, other planets around the sun, other planets around other suns, satellites around earth, spacecraft around the moon, is the balance of momentum and gravity. Technically, acceleration due to gravity.

2)It’s a bit hard to comment on your point about the speed of Earth’s rotation changing. It’s both true and false depending on the nuance of meaning. Earth’s speed of rotation is steady at a thousand miles per hour. But the length of a day DOES change a bit due to the ellipticity of its orbit around the sun. The 24 hour day is an average over the year. It’s not a bad approximation, it’s plus or minus 20 to 30 seconds per day. Yes the effect IS noticeable on Earth. The total discrepancy moves midday by up to plus or minus 16 minutes total from clock time. Any sundial will generally have a clear explanation next to it.
3)I LOL with you at that comment of his. I’d paraphrase it as it’s all too hard, abandon all rational thought to experts, and join me in mental masturbatory dreams of Jesus.’
The Fundy is prattling gibberish when he speaks of corners, centrifugal discharge, motion changing into free fall, planets erupting from the sun. He’s also mistaken when he says planets cannot escape from the sun’, but that knowledge is only 200 years old, and thus far too recent for a Fundy.
This kinda reminds me of Nancy Leider's notions of orbital mechanics.
She thought comets fell STRAIGHT toward the sun, and were only deflected at the last instant by the solar wind.
Her proof? When a baseball is batted high into the air at an angle, it is moving STRAIGHT downward by the time it lands in the outfielder's glove. (It doesn't, of course, but little things like facts never stood in the way of Nancy Leider.)
Just because there is mathematical agreement doesn't mean you understand the mechanics behind it all.
We have to give him credit for at least getting that part right. There are a few models, but nobody really knows how and why gravity itself works, only its effects.
On the other hand, that's probably not what he meant.
Now THAT is an epic and entertaining thread. 300 pages of people trying, desperately, to knock some sense into the TC, or hoping that he is trolling (he isn't by the by). Fantastic read, far better than any Nicholas Sparks works!

o.O You'ew nor too good at logic
"Better to just follow the accurate teaching of Jesus Christ and leave the heavy stuff to those righteously trained"
Like those that know what they're talking about. Not NicholasMarks
Confused?
So were we! You can find all of this, and more, on Fundies Say the Darndest Things!
