Calling All Amateur Astronomers! How far away are stars? How do we determine this distance? What makes it reliable?

[quote:Anonymous Coward 1417231:MV8xNTU2MzY0XzI1NzE4NDk1X0M2NUNFNEQ4] [quote:Astronut] [quote:Anonymous Coward 1417231] [quote:Astronut] [quote:Anonymous Coward 1460071] Stellar Parallax appears to be one of the biggest scams in scientific history. If you really want to understand this subject, please read the papers by Dr. Neville Thomas Jones, [/quote] I had a feeling this thread was connected to geocentrism. Sure enough, no sooner do I make note of that than Neville Jones links start popping up. Yes, here's a guy who, in order to explain the existence of geostationary satellites in geocentrism, denies the inverse square law of gravity and the law of inertia. He claims that [i]velocity[/i] ceases as soon as a spacecraft's engines are cut off. Yes, this means he claims that deep space travel is a hoax (manned AND unmanned) with the exception of ion engine powered missions, which must run the engines at all times. It's hysterically bad. [/quote] This is a mighty big speculation based on the assumption that most factors involved in the calculations are constant and known. Calculations and formula's are useless when the input info is not verifiable! [/quote] Orbital mechanics is completely verifiable, that's the problem facing Neville. Geostationary satellites in particular are some of the most widespread verification since so many people have satellite dishes that depend on them, which is probably why Neville decided to trash any semblance of plausibility in order to force a solution which would allow for geostationary sats, even if it meant just about everything else had to be a hoax. Few people can verify the rest, so it's easier for him to claim that the rest is a hoax and anyone who says otherwise is just in on the conspiracy. [/quote] Geostationary orbits are easy they are very close. We are talking about distant galactic objects. One idea in particular that puzzles me is the assumption that we know exactly how light travels and behaves. How can we be so sure? All your calculations are based on the theory of how objects in space behave. Basically assumption and speculation, in other words you are guessing. Still they are intelligent and well thought out but just guesses. [/quote]
Original Message
How do we measure how far away stars are from us?
What method of measurement is used?
How do we know its accuracy?
I bring up these questions out of serious curiosity.
