edit: These forums suck. They used to let you preview the poll before you submitted the thread to masses of NSG.

Anyway... I came across this site whilst I was browsing the wonders of the internet.
http://isthis4real.com/orbit.xml

It's a need little... thing... that lets you model orbits. Specifically a earth-moon type orbit.

It poses the idea that moon cannot have came into orbit from outer space because it would have spiraled and crashed into the earth many years ago. It also says that the moon cannot have entered into orbit due to a comet crashing into the earth and spitting up the moon into orbit as it would have escaped the earth's gravitational pull many years ago.

It then goes on to suggest that it must be god who put moon in orbit as it cannot have occured naturally.

Being a godless infidel I couldn't accept this explanation and pondered on the subject for while before coming up with two distinct ideas. I . (which I can't numerically prove are.

This is no mere time warp; I think the thread was going backwards.

This site ignores the fact that the moon is drifting away from Earth at a constant rate and will eventually be lost from its gravity. Dur. Trust creationist morons to selectively ignore facts to suit their worldview.

they have this test, where it asks three questions, and they are yes/no, but you can't choose no to any of them. They make it to where you have to fall into their trap...damn them

I hate it when people have impossibly high standards. This is why I don't like religions like Christianity. They are purely for people to control others with.

The moon is going away and eventually will be gone...although the sun might engulf us first...

I think that thing is purpose built to not work. Encarta has the same thing and it works almost every time it should. This thing doesn't even let you move the starting point like Encarta does.

the model is flawed. it gives the size of the moon as too small, and the gravity of the earth is way too large.

Anyway i had a go, and i managed it. try "outer space, 180, 5"

Oh dear lord. So much wrong with this thing.:headbang:


For instance, I think the moon is a bit bigger in comparison to the earth, than what the model shows. Which would give a more balancing act of the gravitational pulls of bodies. But as it is, they make it as if the earth is a giant vaccuum cleaner. Stupid creationists.

In addition to the fact that the model is not at all to scale, it also completely discounts external forces. Besides, the moon is not in a perfect orbit, it gets farther from the Earth every year.

The average distance from the Earth to the Moon is 384,399 kilometres (238,854 miles), which is about 30 times the diameter of the Earth.

Looking at the source code I can tell it's purposely designed to fail. It's set to use 0.9m/s2 (a bad approximation) for Earth's gravitational pull and 0.5m/s2 for the Moon's, which is completely off since it's true value is closer to 1.6m/s2.

It's also flawed in assuming that angle values etc must be whole numbers. Again, the simplistic science-naive viewpoint of creationists proves only their stupidity and nothing else.

Hmm...You can put in decimal amounts for the power...Wouldn't it be so awesome if, knowing it's designed to fail, someone put it up anyways?

Yeah, but the actual value for an impact angle could practically be an irrational number.

Pfft. That people fail at everything. I was able to put the Moon into an orbit on my third try using an angle of 15 and force of 4.

Note that I said an orbit because that's all that's really required. Unlike the ridiculously close circle they put in there, in nature orbits are elliptical and they tend to be further from the main body.

Oh, well, it's an interesting game, though.

Incedentally, and ground level, launch 180, the difference between flying into space and rolling on the ground is somwhere between power 11.2666787776875 and 11.2666787776876

it's somewhere between 11.2666787776875940707554946129675 and 11.2666787776875940707554946129676

Obviously the exact value is what you need to make it orbit. My friends, this number will clearly delineate between Science and Religion. Comrades, we have found...The God Number.

It's like Pi. All we need is a program that can do this mechanically.

Than we can solve their problem, and wait for them to deny that it was only one possible way, and when we find a bunch of answers (getting rid of the one that starts from outer space, since by design, that one is suppose to be flawed I think. Notice how it always returns to the point of starting.) and they'll say that the model was wrong because the true size of Earth in comparison to the Moon, and the size between them, and a bunch of other wrong things in this model.

I can't remember precisely, but it was a really low launch angle (like 2degrees) and probably power of 9.

EDIT Yep, that works. People would be constantly crushed on one side of the planet, mind...
