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

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.

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..

I'm waiting for the question referring to this piece of scripture.
  1. Revelation 12:4
    And his tail drew the third part of the stars of heaven, and did cast them to the earth: and the dragon stood before the woman which was ready to be delivered, for to devour her child as soon as it was born.

Don't confuse them. We have to convince them that the earth revolves around the sun and is not flat... lol.

Oh goodie.

So tell us what the baseline is for the triangle when measuring star distances. How do they determine the baseline?

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.

you could also travel due east for a while and end up where you started. Kinda rulez out a flat earth...duh.

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.

He doesn't want to learn because he thinks he already has the answer poor lost soul:(

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.

We measure with light Doc. if you did a little research you might understand such things instead you chose to bury your head in the perverbial sand.

Tell you what go to home depot today and buy an infrared tape measure (they measure with light)
and then check the distances with a standard tape measure in your own house maybe then you won't be so quick to scoff at modern science.
BTW to answer your next question before you ask they use the same principles used in astronomical calculations in the infrared tape measure TRY IT

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.

Nope sorry grandpa the principles used are the same whether figuring out how far it is to the sun or across the room as I said to Doc. go to home depot and buy an infra red tape measure same principles apply try it.

Why don't you go up in a shuttle and see for yourself?
