One advantage of the numerous distance-measuring schemes in use, which overlap over a range of All American Dad shirt from nearby to very distant, is that astronomers can calibrate and corroborate their measurements with multiple approaches. Such calibrations and corroborations thus lend an additional measure of reliability to these schemes. Indeed, by comparing results using different methods, weaknesses have been identified in certain schemes. In most cases, additional studies have demonstrated ways to guard against and correct for known difficulties. As a single example of these multiple approaches, prior to 2011 the distance to the Pinwheel Galaxy was determined, based on measurements of Cepheid variable stars in the galaxy, to be 20.9 million light-years, with an uncertainty of 1.8 million light-years. As of September 2011, measurements of the light output of the 2011 Type Ia supernova in the Pinwheel Galaxy are completely consistent with this distance figure…. In short, distances to astronomical objects can be and have been measured with substantial accuracy and reliability. For the most part, the calculations involved employ only basic mathematics taught in high school. Thus the overall conclusion of a universe consisting of billions of galaxies, most of them many millions of light-years away, is beyond reasonable doubt at the present time..

When Delores spent his first night actually out with the other chickens in the Sugababes Too Lost In You Shirt, I was anxious about how he would handle himself, as he was pretty shy. After a few false starts (and getting pushed off perches by the other chickens) he chose a walnut branch that lead to the night perches and slept on that. When Delores became a big, beautiful Golden Phoenix adult rooster, I thought the hens would probably make absolute fools of themselves trying to get his attention – and if he ignored them it would serve them right! I suppose I should have done something about the name – but Delores responded to “Delores” and appeared fine with it. (Also, my Aunt Delores would have been devastated if I changed his name.) A friend suggested calling him “Del” – which sort of made sense – but that sounded like he was lead singer in a retro 60’s band. As long as Delores didn’t mind – and let’s face it, he didn’t care – I was perfectly content to have a sweet rooster named Delores.
