all knowledge is Gods first it is he who gets all the Glory not me Doc.I always credit my sources. I suggest you do to. Plagerism is not good.

I've been looking on the internet for how astronomers calculate distances and it seems like they all assume at least one thing and then take that assumption and apply it to the rest of the solar system and universe.
I don't really understand exactly how they go about it but somehow they figure when Venus is tangential to the Earth and the sun that gives them a proportion for how much farther away the sun is from the earth than from Venus. They state Venus is 70% as far from the sun as Earth. And apparently some guy named Arius or something did the same thing except with the moon.
In geometry you have to know a distance before you use a sin or tangent. So someone is guessing at something it seems to me. Unless you really did run out there with your tape measure...
I don't know. I still say they assume too much.
Grandpa, all cosmic distance measures are ultimately based on plane geometry theorems.
For example, if one knows the length of the base of an isosceles triangle, then measurements of the angles at either end of the base will deliver the distance to the vertex of the triangle. This is known as the direct distance method. There are indirect methods as well.
Here's how it's done: Properties of Stars
Good one AOK I was beginning to think I was the only one here with any triginometry skills!
Of course in 3 dimensional calculations you need 3 points of referrence for calculations but that's another ball of wax..
word play or an honest question?

Oh goodie.
So tell us what the baseline is for the triangle when measuring star distances. How do they determine the baseline?
Don't confuse them. We have to convince them that the earth revolves around the sun and is not flat... lol.
Well its not flat. You can watch a boat come over the horizon to see the Earth isn't flat. And probably some satellite imagery could show us. I'm not trying to be purposefully dense. I accept science, its just their assumptions I'm not sure about.
Ha ha. I was going to ask that question.
Oh goodie.

Why not just take the time to read the article as that's clearly explained instead of not reading the article and asking a question that is already answered in the article? You make no sense.

hehe let the circular reasoning commence.

Satellite imagery proves the earth rotates so that assumption is debunked!
Well its just using proportion, isnt it? They don't have actual distances. They use the distance from the earth to the sun as an AU and everything else is proportioned off of that. So the nearest star is 200,000 au's. They've got an idea of proportion but size they are probably guessing.
How do you know satellite imagery isn't proving the earth is still? Because it looks like the earth rotates? How would you know which one was still? without assuming.
