[quote:SaveTheLivingEntities:MV8xNTU2MzY0XzI1NzA3OTE1XzYzNUVDNDY1] Actually, here is what I'm really going on about. http://astronomyinformation.org/astronomy/3.htm [face=Verdana]"[i]In previous chapters we have proven that the ability of telescopes to see distant stars has been greatly exaggerated. Experiments have also proven that the distance at which the sun would be barely visible by the naked eye or a telescope has also been greatly overstated. Here we will explore some of the problems regarding parallaxes and star distances. Astronomers have tried to determine star distance by a method called trigonometric parallax. The distances that astronomers calculated using this method are in turn used as yard sticks to determine the distances of all other, much farther, objects. Trigonometric parallax is one of the main methods that astronomers use to estimate the distances of remote objects such as galaxies. If this foundation is proven to be doubtful, then, automatically, the whole scale of measurements in astronomy regarding the distances of stars, star clusters, galaxies, etc., like falling dominoes, comes into question.

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.
[UPDATE]
Hello everyone. The topic has evolved to a discussion on this information.
