Because you have no means of validating your measuring system by direct observation.Originally posted by Scott J:

So just how far away are the clouds of Magellen, naked eye objects that they are? Why doesn't seeing them at 200,000 light years distance qualify as seeing things outside our solar system?
You can assume things constant so long as you acknowledge that they may not be and that the results could vary radically if they are not.
All I am really asking for is basic honesty and integrity. </font>[/QUOTE]In 1987 astronomers in Australia observed a supernova in the clouds of Magellen. Over the years since that time they prepared pictures of the light spreading out from that supernova and illuminating dust in the neighborhood. The light spreading out from the supernova takes up space in the sky and shows us how far away they are merely by how much room in the sky a light year or so actually turns out to be in the neighborhood of the clouds of magellan. The distance turns out to be 170,000 light years.

Now I know I'm slow and dim and such, but these seem to be honest folks, with integrety, and I begin to form an alternate opinion of people who say these observations aren't observations and that seeing and measuring these things isn't seeing and measuring things.
